I bought 2 solar panels on Ebay. The dimensions of each are 55x80mm. These are both encased in clear resin. I connected them in parallel and got 7vdc, and 60ma from both of them combined. This is pretty respectable seeing how it was a sunny but winter day about noon. Each is rated for 6vdc 0.6w, so that's 10ma max. But solar panels don't ever get the output they are rated for due to how they are rated in the lab.
For $1usd with free shipping, that's enough to charge a small battery, like an AA, but not really a powerbank.
Update June 2019: The epoxy-coated solar panels get cloudy the more they are in the sun, thus reducing their effectiveness. Caution is advised when using these.

Pesticides found in 207 food samples by FDA study.
The FDA's Pesticide Monitoring Report from 2015 contains a report on what pesticides were found in foods. It's a good idea to show these studies to show how dangerous some of the pesticides are, and how widespread they are. Organizations have known this for quite a long time. But some organizations that claim to protect your health are bought out by industry.

Excerpts:
In FY 2015 (October 1, 2014 through September 30, 2015), FDA analyzed 5,989 samples in its regulatory monitoring program: 5,572 human foods and 417 animal foods. Because the violation rates of import samples are generally higher than for domestic samples, FDA tests more imported than domestic commodities (4,737 import and 835 domestic samples). We collected imported human food samples from 111 countries and domestic human food samples from 39 states, the District of Columbia, and U.S. territories.75% of food samples were found to be contaminated.

Glyphosate Use and Cancer Incidence in the Agricultural Health Study
Glyphosate Use and Cancer Incidence in the Agricultural Health Study
JNCI: Journal of the National Cancer Institute, djx233, https://doi.org/10.1093/jnci/djx233
Published: 09 November 2017
There is strong evidence of glyphosate exposure linked to Non-Hodgkins Lymphoma (NHL). The study did not links between glyphosate exposure and NHL, but did find some links between glyphosate exposure and acute myeloid leukemia (AML) compared with people who never used glyphosate.
The study covered licensed pesticide applicators from North Carolina and Iowa. This graph shows some correlation between glyphosate exposure and NHL, but not with other cancers.

Some EU members say no to glyphosate 5 year renewal
Some EU members, realizing the danger glyphosate puts humans and wildlife in, have voted no to renew Monsanto's 5 year license in their areas.14 countries voted for the renewal, 9 against, 5 abstained, including Germany. France has already agreed to a 3 year renewal so the deadly chemical can be sprayed on GMO and non-GMO crops. For the vote to pass, two conditions must be met.

- 55% of EU countries must vote in favor, and
- countries that support the vote must represent at least 65% of the total EU population. So larger, more populous countries have an advantage in voting.

Can Tesla help rebuild Puerto Rico's power grid?
Tesla (maker of electric cars) wants to help Puerto Rico rebuild their power grid. The hurricane destroyed most of the power grid, and in some areas, 100% of people were out of power for 2 or more weeks.
Tesla wants to help build a new solar power grid by storing power in giant battery banks, and distributing that power over power lines. This would be a networked design so there would be solar collectors and battery banks in several different cities. The PR power company was on the verge of bankruptcy when the hurricane hit so the power infrastructure was already poor, damaged, and need of repair at best.
Tesla has already sent hundreds of Powerwalls to help people, but those need electricity to recharge.

1985 EPA memo says glyphosate causes kidney tumors
A recently found archived document form 1985 shows, before the EPA was bought off by Monsanto, that the EPA thought glyphosate caused kidney tumors. Monsanto claims tumors are unrelated to glyphosate exposure by showing past studies. EPA claims past studies have too much variation to nullify the no tumor claim.

DelMonte to eliminate BPA and GMOs
Del Monte, a major US food producer, announced that it would be eliminating BPA in can liners. But they must use another phthalate, which has not been shown to be safe. They also want to eliminate GMO foods in their products. But Roundup is not just used on GMO food, it's used on all crops to kill it all at the same time, whether the crop is GMO or not.

BPA found in 16,000 foods and beverages
EWG now has a database showing 16,000 foods contaminated with the endocrine-disrupting chemical BPA. BPA (bisphenol A) can disrupt hormones in the human body creating a host of problems. BPA is a one of a class of chemicals called "phthalates". BPA makes plastics softer so they don't crack. So they are used in plastics for can liners, plastic containers, and just about every plastic. Plastic without phthalates is brittle and breaks easily. Plain plastic is simply not usable in everyday life.
Containers that are BPA free are not safe. Manufacturers simply replace one phthalate with another, which would be even more damaging to people and animals.
How to avoid exposure to BPA
Containers that are BPA free are not safe. Manufacturers simply replace one phthalate with another, which would be even more damaging to people and animals.
How to avoid exposure to BPA
- In most cases it's impossible to completely avoid exposure to BPA. Food ingredients are shipped to factories in plastic wrap or plastic containers. But the longer the food sits in contact with the BPA, the more BPA it likely has.
- Buy food sold only in glass jars.
- Store food in glass jars. The resealable glass jars with a latching lid and rubber seal are more and more common in the US these days.
- Most cans have plastic liners, but especially for acidic foods like tomatoe products and green beans. Avoid canned foods.
- Avoid freezing food in plastic bags unless the food is wrapped in waxed paper.
- Do not allow food to come into contact with plastic for long periods of time.
- Plastic syringes and IV drip bags also contain BPA.

U.S. experts doubt EPA curbs on Monsanto, BASF herbicides will halt crop damage
US specialists doubt that reducing the sale of dicamba, sold by Monsanto and BASF, will actually slow down crop damage. Monsanto is releasing dicamba-resistant soy beans. Does dicamba get into every cell, so that it ends up in the food system?
Overspray of dicamba, trade name Xtend, to neighboring fields is responsible for millions of dollars in crop damage. Depending on soil conditions, Roundup can remain in the soil for up to 4 years, damaging future years of crops. Does dicamba do the same?

Roundup kills your energy system?
What is the Shikimate pathway?
The Shikimate pathway is a seven step metabolic route used by bacteria, fungi, algae, some protozoan parasites and plants for the biosynthesis of folates and aromatic amino acids (phenylalanine, tyrosine, and tryptophan). Since animals need these folates and amino acids, but do not have this pathway, these nutrients must be provided by gut bacteria. Is this how Roundup interferes with a human's energy level, by disturbing gut bacteria?
From Wikipedia: The seven enzymes involved in the shikimate pathway are DAHP synthase, 3-dehydroquinate synthase, 3-dehydroquinate dehydratase, shikimate dehydrogenase, shikimate kinase, EPSP synthase, and chorismate synthase.Even since the 1980s, one cause of Myalgic encephalomyelitis (formerly Chronic Fatigue Syndrome) has been thought to be a dysfunction of the human cell mitochondria. But now with more research on how critical gut bacteria is to humans, and how glyphosate (and a diet with sugar) destroys the good gut bacteria, this study might be able to show how Roundup causes its damage, and may be a cause for CFS.
Full study is on Elsevier, which is paywalled. But here is the abstract.
Abstract
The shikimate pathway is a metabolic route for the biosynthesis of aromatic amino acids (AAAs) (i.e. phenylalanine, tyrosine, and tryptophan). A key enzyme of shikimate pathway (5-enolpyruvylshikimate-3-phosphate synthase, EPSPS) is the target of the widely used herbicide glyphosate. Quinate is a compound synthesized in plants through a side branch of the shikimate pathway. Glyphosate provokes quinate accumulation and exogenous quinate application to plants shows a potential role of quinate in the toxicity of the herbicide glyphosate. Based on this, we hypothesized that the role of quinate accumulation in the toxicity of the glyphosate would be mediated by a deregulation of the shikimate pathway.
In this study the effect of the glyphosate and of the exogenous quinate was evaluated in roots of pea plants by analyzing the time course of a full metabolic map of several metabolites of shikimate and phenylpropanoid pathways. Glyphosate application induced an increase of the 3-deoxy-D-arabino-heptulosonate-7-phosphate synthase (DAHPS, first enzyme of the shikimate pathway) protein and accumulation of metabolites upstream of the enzyme EPSPS. No common effects on the metabolites and regulation of shikimate pathway were detected between quinate and glyphosate treatments, supporting that the importance of quinate in the mode of action of glyphosate is not mediated by a common alteration of the regulation of the shikimate pathway. Contrary to glyphosate, the exogenous quinate supplied was probably incorporated into the main trunk from the branch pathway and accumulated in the final products, such as lignin, concomitant with a decrease in the amount of DAHPS protein.

Sherman County may be issuing a Court Order on May 22, 2017, to quarantine Azure Farms and possibly to spray the whole farm with poisonous herbicides, contaminating them with Milestone, Escort and Roundup herbicides.And then the state will charge them for the service. Like the Chinese government charge the family of the dead after a criminal has been executed.

How to power things using batteries and alt power, part 2 of 2
Part 2 of 2
Power draw from the battery
If all 4 amps is being used on the Amazon inverter, how many amp hours are actually being drawn from your battery? 4 amps / 0.8 (efficiency rate), or about 5 amps per hour. Worst case scenario for an inverter that provides 4 amps: If your battery holds 20 amp hours, it will last for 20 amp hours / 5 amps per hour, or 4 hours if there is no power being added to the battery. If your battery holds 80 amp hours, it will last for 80 / 5 amps per hour, or 16 hours of continuous use with no power being added to the battery.
Examples of batteries
Below is a variety of batteries. I don't know about their quality, but let's compare the cost per amp hour of capacity. Do not use "cold cranking amps" for capacity, find the amp hours rating.
- Optima Marine battery, $200 for 55 amp hours. Cost per amp hour: $3.64usd
- 12v battery, $100 for 35 amp hours: $2.86usd

How to power things using batteries and alt power, part 1 of 2
I've been looking into using solar power and batteries to power things. My first kit is used to charge a battery using a small panel, about 12" x 8", and the battery powers an LED light. The battery box also has a 5vdc USB port for charging USB things. Or simply for powering a USB device like a USB fan.
Terms
Here are some terms to get you started.
My next step was looking into using a solar and battery system to power my flat screen TV.
Alternative power usually uses an energy producing device to charge up a battery. If you use solar power (photovoltaics) you are using a solar panel to charge up a battery, and the battery stores energy for later use. You won't need lights during the daytime when the sun is out, so the battery provides power for nighttime use.
In the case of wind power or hydro power, in both cases they turn a generator to produce power, which then charges a battery for energy storage.
But how do you size the system to meet your needs? A battery provides DC power but your TV needs AC power. So you will need an inverter to change from DC to AC power. Buying an inverter based on watts it supports is not helpful. You need to look at relevant energy units, volts and amps. While watts = volts * amps, watts is just a very general way of looking at things. The inverter must provide both the volts and amps our TV needs.
My TV is rated at 12vac and 50 watts (labeled "50w" on the back of the TV). This does not tell us the amps that it draws/uses so we must calculate that. 50/120vac = 0.417 amps, or 417 milliamps (called "mA" with a big A). Amps is how much power it uses per hour. "Amp hours" is for battery capacity, and is how many hours a battery will provide 1 amp. A 1 amp hour (Ah) battery provides 1 amp for 1 hour before the voltage gets too low to be useful.
Terms
Here are some terms to get you started.
- Amps: how much current a device draws, per hour. A 1 amp device uses 1 amp per hour.
- Amp hours: the capacity of a battery. A 2 amp hour (Ah) battery provides 2 amps for 1 hour, or 1 amp for 2 hours, or 0.5 amps for 4 hours.
- Volts: volts is another measurement of a battery. Devices have a minimum voltage they need to run. A radio powered by 2 AA batteries needs about 3.0 volts to run (2 * 1.5 for each AA). An LED can work on a range of voltages. If the ideal voltage for maximum brightness of an LED is 3.3vdc, then as the battery is used up, the voltage drops, and the LED gets dimmer. The LED might go out at about 2.9vdc.
- Watts: A general unit of measure which is volts * amps used. A 12vdc device that uses 0.5 amps per hour uses 12 * 0.5, or 6 watts per hour. Electricity in the US is charged by 1000 watts per hour, or 1 kw per hour.
My next step was looking into using a solar and battery system to power my flat screen TV.
Alternative power usually uses an energy producing device to charge up a battery. If you use solar power (photovoltaics) you are using a solar panel to charge up a battery, and the battery stores energy for later use.

Report: Massive misconduct and corruption at CDC
The report points out Dr. Poul Thorsen, a Danish scientist who
has been indicted in 2011 by U.S. authorities for allegedly stealing millions
from the CDC and tainting research to hide the dangers posed by
vaccines. Thorsen remains on the loose.
Report PDF is here.
In addition to uncovering other information, Kennedy and officials at the World Mercury Project say they have found evidence that Thorsen and his collaborators did not get permission from an Institutional Review Board (IRB) to carry out their research, published in the New England Journal of Medicine in 2002 and the journal Pediatrics the following year.
“In 2011, the Department of Justice indicted Thorsen on 22 counts of wire fraud and money laundering for stealing over $1 million in CDC grant money earmarked for autism research,” the statement notes. “The product of Thorsen’s work for CDC was a series of fraud-tainted articles on Danish autism rates that, today, form the backbone of the popular orthodoxy that vaccines don’t cause autism.”The CDC must be covering up big time. I still wonder why people would assume a mercury compound, injected into people, is just assumed safe. Perhaps it was just for money. Like these other US products that were assumed safe.

Certification for glyphosate free foods
The Detox Project now has certification for glyphosate-free food products sold to consumers, and also ingredients used in products.
Why is this important?
Detox Project food testing FAQ here.
Why is this important?
- One German study found glyphosate and metabolites in urine of all people tested.
- High levels of glyphosate found in major American food brands.
- Glyphosate is thought to disrupt gut bacteria, which are important for overall good health.
- Most corn, soybeans, and wheat crops in the US are sprayed with glyphosate to kill it all at once for harvest a few days later. More food found with glyphosate in it.
- Glyphosate is absorbed into every cell of the plant, it cannot be washed off.

Teflon
Teflon is a brand of a type of fluoropolymer coating created by DuPont, is also called PTFE (polytetrafluroethylene). It's used on lots of cookware to make them non-stick, on vascular grafts used in coronary bypass surgery, ironing board covers, heat lamps and prosthetic limbs. But it can be dangerous.
EWG has some studies showing it kills birds. Here's a quick summary from EWG:
EWG has some studies showing it kills birds. Here's a quick summary from EWG:
Studies show that thermal degradation of Teflon leads to the slow breakdown of the fluorinated polymer and the generation of a litany of toxic fumes including TFE (tetrafluoroethylene), HFP (hexafluoropropene), OFCB (octafluorocyclobutane), PFIB (perfluoroisobutane), carbonyl fluoride, CF4 (carbon tetrafluoride), TFA (trifluoroacetic acid), trifluoroacetic acid fluoride, perfluorobutane, SiF4 (silicon tetrafluoride), HF (hydrofluoric acid), and particulate matter. At least four of these gases are extremely toxic - PFIB, which is a chemical warfare agent 10 times more toxic than phosgene (COCl2, a chemical warfare agent used during World Wars I and II), carbonyl fluoride (COF2 which is the fluorine analog of phosgene), MFA (monofluoroacetic acid) which can kill people at low doses, and HF, a highly corrosive gas.Teflon can also appear on heat lamps. One University of Missouri study showed a 52% mortality rate for chicks. These chicks showed severe pulmonary damage and lung lesions. Even temperatures as low as 325F can cause deadly off gassing.

Solid electrolyte rechargeable alkaline batteries on the horizon
Newer, rechargeable alkaline batteries might be able to compete with lithium batteries by using a solid electrolyte polymer developed by Dr. Mike Zimmerman, who was no Nova Science Now (see this article). This solid polymer can be used in lithium batteries to prevent sudden explosive discharges, or in alkaline batteries that currently use a paste electrolyte.
But what is C? C is the capacity of the battery. If the battery has a capacity of 1000 milliamps, then charging at 0.5C means charging it at 500mA, which is a bit too high. For longer life, charge it at 0.25C, or in this case, 250mA.

Green Tech Media.
Zimmerman's company, Ionic Materials, says its polymer tech can make a rechargeable alkaline battery that can be charged and discharged at least 400 times.But the number of recharges depends on how much C you charge the battery at. "Fast chargers" charge at a higher C which reduces the number of times a battery can be recharged to as low as 20-30 times.

Many uses for foam ties
We are all familiar with the wire ties. They used to come on bread or baked goods. They are also used in the garden. But there is a better tie with many uses, it's a foam covered wire tie. Sold here. Here are just a few uses.
Sometimes these are sold at Dollar Tree or other dollar stores so keep an eye out for them.
- Keep headphone or USB cords neat.
- Tie up plants to stakes.
- Hold Christmas lights to a gutter.
- Clip alcohol gel to a cooler, picnic basket, or backpack.
- Keep all pens together in a drawer so you can find them.
- Hang paperclips or binder clips on them and take this with you in your backpack.

Turn any web page into an EPUB
I don't like PDFs because they can't increase the font size while reading them or wrap the words to any device screen size. On a tablet, a PDF leaves me zooming into a PDF and scrolling left and right, up and down, just to read the text. So I prefer EPUB. I found this website to change any web page into an EPUB. My first test was a journal article that had some type of Javascript left side table of contents, and it worked great. The resulting epub removed the Javascript TOC and the EPUB came out great.
They even have a bookmarklet that makes it easier to use. Go to dotEpub.com for more information.
I didn't do extensive testing with a variety of web pages but this would be handy for journal articles that are only available online, or newspaper articles, or saving project or how-to pages.

Micro hydro power can charge your power bank while you shower
There are a couple micro-hydro power generators on Ebay. These are not full kits, you will need to hook up a USB charger board to it to limit the output to 5vdc, and you will have to add a female USB port. This one hooks to any standard US pipe water supply, like your shower, and is said to generate 5-12v of power. But tests show it only generates 5v with no load, and 4.2vdc with a load. 4.2vdc is not enough to charge your power bank, but if you add a power booster to boost it to 5vdc it should work. This means it will generate power while you shower, wash your hands, or while the toilet tank is filling with water. You get more use out of the flowing water.
This is the same style as above and is stated to generate 100ma, at no load, which sounds more accurate.
This one has no case and is an open turbine. Again, it is unlikely to meet it's stated specs with a load on it. The threads might be for standard US water supplies, but I can't be sure. Also note that a US garden hose thread is not the same as a US water supply pipe thread. But there are adapters to go from one to the other. Some specs for this item:
This one with a case, claims to output 8.8vdc to 15vdc. At $8.10usd out the door, higher than the first item mentioned above, let's hope it outputs 5vdc even with a load.

Printable solar panels
There has been news about printable solar cells going back to 2008-2012, and it's worth looking into. There should have been consumer products on the market by now (2017) since these cells are cheaper to print (though the article I saw didn't say if they are cheaper per square inch or cheaper per watt of power generated).But I haven't been able to confirm that the flexible solar cells are indeed printed.
So here is a smattering of articles to get you going.
2008: This article mentions Konarka company making printed solar cells. http://inhabitat.com/printable-solar-cells-demonstrated/
2011: News from MIT. http://news.mit.edu/2011/printable-solar-cells-0711
2017: An article from Science Daily, Feb 2017. https://www.sciencedaily.com/releases/2017/02/170216142800.htm
June 2017. University of Newcastle in Australia print solar cells. These cells are translucent and let some sunlight in while at the same time generate power. These are great for putting in south-facing windows in the northern hemisphere. http://planetark.org/news/display/1281
If you have a link to print your own solar cells at home, please leave a comment with the link to share with others. Thanks!

A new innovation could make printing solar cells as easy and inexpensive as printing a newspaper. Researchers have cleared a critical manufacturing hurdle in the development of a relatively new class of solar devices called perovskite solar cells. This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator.Wikipedia: Inkjet solar cells. Retrieved Aug 21, 2017.

Low-powered LED light in the works
From Newsatlas: A new flat-panel LED light could reduce power use tremendously. Scientists at Tohoku University in Japan have made a cheaper LED lighting device in the form of a flat panel that gets efficiency of 60 lumens per watt, which is pretty darn good for their simple device that has not been tweaked. It uses nanotubes to get this kind of efficiency.
Each carbon nanotube acts similar to a cathode ray tube when a strong electric field is applied. The electric field requires 5kv to work but the device itself uses very little power.
People have been working on other ways for LEDs to use less power. Some pulse power so fast the human eye cannot detect the LED going off and on. One project is the TritiLED which aims to light a dim LED to be used as a marker, for about 10 years. There is also the Decade Flashlight.
Update Nov 2018: My Tritiled, acquired in July 2016, has been running for 2 years straight with no problem. It's never been turned off.

Super efficient nano-LED research
This is not the same as a super efficient LED circuit where a battery could light an LED for 10 years. This is a whole new LED technology at the nanoscale.
One of the larger bottlenecks between microchips is the data connections. An optical connection, rather than a wire connection, would speed things up, but a light source small enough was not available until now. Scientists at TU Eindhoven made a nano LED that is 1000 times more efficient and can communicate at gigabits per second.
But since this article is from 2017, expect to wait another 8-10 years before we see these things in consumer devices... if it can be made at a reasonable price that is.

Monsanto tries to get Seralini study retracted
The study by GE Seralini showed that even low amounts of Roundup had toxic effects on rats over the long-term. This includes liver and kidney damage. Seralini's other study where rats got tumors was done incorrectly as they used a type of rat that is supposed to get tumors.

Evidence Monsanto tried to bribe scientists
Roundup is a big money maker for Monsanto so it's no surprise that more evidence that Monsanto tried to influence writes and bribe scientists has come to light.
From this website, attorneys asked to see Monsanto's "protected documents". The more Monsanto tries to push, the more it looks like people are on the right track to exposing corruption. Quote:

NIH and EWH recommend ending use of triclosan
Triclosan likely hurts a person's health more than it helps it, and ever-present triclosan is instrumental in creating super bugs. The statement summary:
Source
The Florence Statement.
You can search the NIH NCBI library of studies here.
The Florence Statement on Triclosan and Triclocarban documents a consensus of more than 200 scientists and medical professionals on the hazards of and lack of demonstrated benefit from common uses of triclosan and triclocarban. These chemicals may be used in thousands of personal care and consumer products as well as in building materials. Based on extensive peer-reviewed research, this statement concludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms. Evidence of other hazards to humans and ecosystems from triclosan and triclocarban is presented along with recommendations intended to prevent future harm from triclosan, triclocarban, and antimicrobial substances with similar properties and effects. Because antimicrobials can have unintended adverse health and environmental impacts, they should only be used when they provide an evidence-based health benefit. Greater transparency is needed in product formulations, and before an antimicrobial is incorporated into a product, the long-term health and ecological impacts should be evaluated. https://doi.org/10.1289/EHP1788

California declares Roundup as cancer-causing
On some things California ignores the science, but since I've read the science behind toxic Roundup, and how you can't wash it off anything, and how it's absorbed into every cell of the plant, and how it's used on many more than just GMO crops, I have to agree with Cali on this one. Roundup is sprayed on non-GMO crops as well, to kill all the plants at the same time for harvest.
The US EPA says glyphosate is safe, but there are emails which show probably collusion with biotech. Another EPA scientist was fired for saying biosludge is toxic. Biosludge is what is left over after raw sewage is treated, and it is often sprayed on food crops in the US. Even a Monsanto exec admitted they faked data in studies. And Richard Goodman, a former Monsanto employee, was asked to write a piece supporting Roundup's "safety", and a few days later received a promotion at his university.

California will add glyphosate, the active ingredient in Roundup herbicide, to the list of chemicals known to the state to cause cancer on July 7, the state’s Office of Environmental Health Hazard Assessment (OEHHA).Well no, they don't know it, no one really knows if glyphosate causes cancer, but it's a good bet it does. Correlation is easier to prove, but causation is nearly impossible to prove. Let's call hyperbole what it is, since it's not news nor fact. Here are some interesting studies.
- PAN has list of studies showing harm of glyphosate.
- Graph showing multiple studies on glyphosate, study conclusions, and cancer risk. There is correlation between glyphosate exposure and non-Hodgkins lymphoma.
- Seralini wins lawsuit showing biotech is meddling in studies.
- Tests and studies about Roundup toxicity.
- Consensus by scientists: Roundup is bad.
- 2015: IARC declares glyphosate probable human carcinogen. Article here.
The agency originally announced the move in September 2015, but Monsanto—the producer of Roundup—filed a lawsuit to stop it.If Roundup is safe, why the lawsuit from biotech? What do they have to hide?

Pediatricians urge EPA to ban pesticides that hurt developing brains
Chlorpyrifos was scheduled to be banned but the EPA is not going to ban it after all. The American Academy of Pediatrics is a nonprofit professional organization, sent a letter to the EPA about this pesticide. Children and their brains are especially vulnerable to chemicals because chemicals can cause brain changes which are permanent. Big Big-Agro is more about money than safety, and this is why many dangerous chemicals are still used on food.
Some portions of the letter:

Some portions of the letter:
Children come into contact with pesticides daily through air, food, dust, and soil, and on surfaces through home and public lawn or garden application, household insecticide use, application to pests, and agricultural product residuesChemicals are especially dangerous if they affect brains (which affects later behavior) or act as hormones like other chemicals do, or remain in the food or environment long-term (like glyphosate).
Epidemiologic studies associate pesticide exposure with adverse birth outcomes, including preterm birth, low birth weight, congenital abnormalities, pediatric cancers, neurobehavioral and cognitive deficits, and asthma. The evidence is especially strong linking certain pesticide exposure with pediatric cancers and permanent neurological damage.

Lumir: a candle-powered LED light
Lumir, the LED powered by a candle. I can see why this would be useful. It's hard for many people, especially older people, to read by a single candle. But I can also see why people would not understand the concept. I can see them thinking "Why would I use a candle if I could just use my $4 LED flashlight or headlamp?"
That's a valid thought. But the technology in Lumir is pretty neat if a bit impractical for many western nations with power. However for nations without power, this might help them study at night by generating enough light to read by. However Lumir is much more expensive than some of the other solar charged lights for Africa.
There are several variations of Lumir and Lumir Spot would be the best for reading a book or magazine.
This appears to use a thermoelectric generator (TEG) and a voltage booster. But TEGs don't product much power, and the voltage boosters to boost the volts up high enough for an LED are expensive.
Wow! It seems they are $109usd on Amazon now.

The REAL story behind Trump and clean water
During Obama's reign, he extended the Clean Water Act to small streams, some of which only contain water for some months of the year. Trump's rollback of this rule would only roll back that addition: small streams that would be covered under the Clean Water Act.
The Obama rule tried to expand the definition of "navigable waters", waters where you can travel on a boat on them, to included 1 inch deep streams, and stream beds that didn't even have have water in them for parts of the year! This includes drainage ditches on the side of the road.
The claim behind the hysteria: 117 million people in the US get their drinking water from small streams. (The footnote says "Streams classified by the U.S. Geological Survey as intermittent, ephemeral or headwater streams.") Intermittent, and ephemeral, mean the stream is not even there the whole year! From the USGS PDF:
Since "headwaters" were grouped with temporary streams in the 2009 EPA study, this makes the 72 million number suspicious.

- Ephemeral: "Contains water only during or after a local rainstorm or heavy snowmelt."
- Headwater from here: "(1) the source and upper reaches of a stream; also the upper reaches of a reservoir. (2) the water upstream from a structure or point on a stream. (3) the small streams that come together to form a river. Also may be thought of as any and all parts of a river basin except the mainstream river and main tributaries."
Since "headwaters" were grouped with temporary streams in the 2009 EPA study, this makes the 72 million number suspicious.

LED light that creates more energy than it uses?
(This is from 2012 but it's still interesting to see if this technology became a product.)
With incandescent bulbs, only 10% of the energy used is converted the light, the rest is converted to heat. Current LED diodes, (as opposed to "LED bulbs" which can contain many diodes) use only about 17% of the energy of an incandescent bulb and do not create much heat, which is good for heat-sensitive applications. For example, when I used standard (incandescent) bulbs in my outside yard light, and winters got to -20F ambient temperatures, the heat from the bulb would eventually crack and destroy the bulb itself from the sheer difference in temperature and the speed at which the bulb heated up. This was long ago and we moved to fluorescent bulbs at the time.
What if there was an LED bulb that produced more energy than it used? MIT researchers claim they have a bulb that creates energy as it uses it. It is 230% efficient, and seems to defy the laws of physics. But how to harvest that energy?
They researchers had a theory of using less voltage.
(I seriously doubt the LED produced light visible to humans but perhaps this concept can be multiplied by using 100s of LED emitters.)

What if there was an LED bulb that produced more energy than it used? MIT researchers claim they have a bulb that creates energy as it uses it. It is 230% efficient, and seems to defy the laws of physics. But how to harvest that energy?
They researchers had a theory of using less voltage.
As you may have guessed, significantly lowering the input power creates a very weak LED bulb. In their tests, the MIT researchers succeeded in generating about 70 picowatts of light from 30 picowatts of energy — an efficiency of 230 percent!Artugo Verdugo comments on the Inhabitat story:
From what I know, this LEDs are more than 100% efficient because they are using electricity+environmental heat to produce light. That means that a large portion of the power being used comes directly from the environment.At this point, neither 30 nor 70 picowatts will light any LED, but it's an interesting observation.
(I seriously doubt the LED produced light visible to humans but perhaps this concept can be multiplied by using 100s of LED emitters.)

Henry Miller: Small amounts of poison are good for you
When people selectively ignore facts, that could be called religion, or a cult. So here's Henry I. Miller. He was the founding director of the FDA’s Office of Biotechnology. He's written numerous articles about GMO foods. He is against labeling GMO foods and against informed decisions. He gets paid for writing articles supporting something so you know his opinion is biased.
Be careful with religious fanatics. The results could be bad.

Can LED lights run for 25 years? 10 years?
Some people are working on circuits to make a dim LED light run for a year, or even 25 years. The initial attempts are to provide "marker lights". These lights are not light enough to use to walk around in the dark or read by, but they are perfect for marking tent pegs, camp sites, or trails at, for example, concerts or camp sites. They can also be used to mark latrines which are often some distance from camp sites, and be used in astronomy to possibly read text (although the lights are not very bright).
Tritium gas tubes last about 10 years, but they are expensive and not available legally in the US for hobbyists. Also there are some fakes sold on Ebay that only last a few months. In the US they can only be sold as part of a watch, gun sight or compass. Ebay does not appear to regulate plain tritium vials sold to the US.

DIY camping stoves
Like to make new things? Like to make new things from discarded items? Like to have a stove to cook on during a power outage? Take a look at these easy to make DIY camping stoves.
The basic stove
The basic stove is called a "hobo stove" and uses small bits of wood or pinecones for fuel. Leaves or paper are sometimes used to start the file. It is normally big enough to put a small one-person pan on top or boil a quart of water. Fuel can normally be found all over the US.

What is the truth about GMOs and pesticides?
EarthOpenSource has a 330pg PDF for free that claims to cut through the corporate BS. But be careful, even well-meaning groups can misinterpret studies or even have their own agenda.
You can read the PDF here. But they want your name and email address, so you will surely be put on a "newsletter" list.
The truth is, many studies from many countries show the harm pesticides can do to people, not just farmers. Some of these studies are covered in this blog. You can click on the right sidebar to find a tag name to narrow down the blog posts you want to see. For example, all blog posts where the main topic is "glyphosate" have the "glyphosate" tag. But tags also are for the main agencies involved (like "FDA"), countries involved (like "India", but not "US"), and the pesticide name (like "dicamba").

Repurposing plastic bottles
In many countries, plastic bottles seem to be everywhere. So instead of filling the dumps up with them, or recycling them, you can make stuff from them. Check out these collections to get some ideas for you.
Many countries suffer from having too much plastic garbage. Many countries dump the garbage in the ocean, and contribute to the various garbage patches throughout the world. The plastic in the ocean breaks down into smaller pieces but never chemically degrades, so a recycling option would be helpful.
However there are some problems. Buyers do not want plastics of various types mixed together as they make a very low grade plastic. They want plastics separated. Illiterate populations will have a hard time telling the different plastics apart even if there are recycle symbols on the plastic, so this could be an impossible hurdle for most poor people in developing countries.

Brazil approves world's first gmo sugar cane
It doesn't matter if the sugar cane is GMO or not, if they spray it with glyphosate it will end up in our food. Glyphosate is sprayed on the leaves, and taken up by all of the plant. It cannot be washed off. Sugar cane is used in LOTS of foods that need a sweetener. Glyphosate is also used to kill a whole crop all at once to increase crop yields, whether the crop is Roundup Ready or not.

Reusing soap slivers
How does one reuse soap slivers? There are several methods.
There used to be a mold where the top and bottom came off. You soak your slivers for 24 hours to make them soft, drain excess water, and press soft slivers into this mold. Then remove a new block of soap. But I can't find this mold on Amazon, Ebay, or Aliexpress. If you can find this soap press, please let me know in the comments.
Some people mash the soap into a muffin tin with a sturdy plastic cup. I would avoid using a glass since some might break in your hands and cause injury.
Some people grate the soap, heat it up in a tin can (pop cans are too light for this), and pour into a waxed Dixie cup for a round soap. Some others use muffin tins, and pour the melted soap in there. You can use muffin tins from the Dollar Tree but spray them with oil before pouring melted soap into them. I'm going to try a silicone mold later because I can push the soap out through the bottom.
Aliexpress link to round silicone soap mold.
I tried to microwave some slivers on 50% power but they just bubbled like popcorn.
If you have an idea that worked well, please leave a comment! Thanks!

New study shows toxic environs cause cancer
- It's not just genetics, but a toxic environment can cause cancer, says a new study from the journal Cancer.
- Researchers examined hundreds of variables that contribute to the overall quality of the environment. These included air pollution, water pollution, pesticide and radon levels, access to health services, and healthy food. (Some studies suggest that tires going on the roads produce a black rubber dust which can make asthma worse.)
- The researchers concluded that poor quality of air and built environment as well as high sociodemographic risk factors had the strongest associations to higher rates of cancer, particularly in urban areas. (Sociodemographic risk factors mean, besides other things, poor people can only afford older, cheap housing, which often has lead paint, asbestos, etc.)

BHA and BHT in cosmetics
Butylated compounds, includes BHA and BHT are commonly found in cosmetics.
Butylated compounds are found in creams, lip products, makeup, hair products, sunscreen, fragrance, antiperspirant/deodorant, and more. Some studies have shown they can influence hormones in the body, can be toxic to some organs, can cause with child development, and may cause cancer. The compounds have many names, but here's one: butylated hydroxyanisole. It has a CAS No. 25013-16-5.
From the NTP report on Butylated Hydroxyanisole:
Currently there is not enough data to say whether BHA causes cancer in humans, but gathering more data on this can take years.
The best action to take is to avoid butylated compounds, and help your kids do the same. Check all lotions, chapstick, lip gloss, and anything they put on their skin.

From the NTP report on Butylated Hydroxyanisole:
Dietary exposure to BHA caused benign and malignant tumors of the forestomach (papilloma and squamous-cell carcinoma) in rats of both sexes and in male mice and hamsters (IARC 1986, Masui et al. 1986). Since BHA was listed in the Sixth Annual Report on Carcinogens, an additional study in experimental animals has been identified. Dietary administration of BHA to fish (hermaphroditic Rivulus marmoratus) as larvae caused liver cancer (hepatocellular carcinoma) in the adult fish (Park et al. 1990).
Currently there is not enough data to say whether BHA causes cancer in humans, but gathering more data on this can take years.

FDA resumes testing foods for glyphosate
- The FDA is one of very few labs that can handle testing of lots of foods. But they need to release the data too, like the amount of glyphosate found in ppm. Very much like lead, there is no safe limit where a person can be exposed to glyphosate. The EPA limits of glyphosate exposure are fake, disingenuous, and dangerous.
- Investigation started about collusion between top EPA official and Monsanto. Some people suspect data was cooked or data unfavorable to Monsanto was simply omitted in testing reports.
- A group of 20 scientists and doctors say glyphosate is not safe at any level.

PiTop: $89 open source laptop!
The PiTop is a laptop that has a Pine64 (similar to a Raspberry Pi) inside it. The PiTop has a 11.6" screen, keyboard, touch pad, 1.2MP camera, Bluetooth 4.0, and more. The MicroSD card slot supports up to 256GB cards. This is a low-end laptop with 2GB RAM, 12GB of storage, and it only runs Linux, not Windows. But there are many free apps for Linux like OpenOffice. This laptop will do fine for word processing, spreadsheets, but may not do great at streaming video.
The 11.6" screen version weights only 2.3lbs (1.04kg).
This might be worth checking out. See full article here.

Dicamba pesticide drift destroying more crops in Arkansas
- Dicamba spray can be lifted by the wind onto neighboring fields. This drifting spray is killing thousands of acres of cotton, soybeans, fruit trees, and more.
- Damage to people from dicamba shows up at much lower concentrations than originally though. (Source.)
- Insurance companies do not cover losses from dicamba. (See here.)
- And Monsanto has been sued over dead crops from spray drift.
- There has also been an assault over continued spray drift onto a neighboring field.

Bee-killing neonicitinoids approval violated the law
- A Federal Court in San Francisco has ruled that the Environmental Protection Agency (EPA) systematically violated the Endangered Species Act (ESA) – a key wildlife protection law – when it approved bee-killing insecticides known as neonicotinoids.
- The EPA also has rules where the cost of approval (or non-approval) must also be taken into account. This lets industry influence the approval process far too much if the company asking for approval simply reports there is little cost associated with the pesticide.
- Judge Maxine Chesney of the U.S. District Court for the Northern District of California held that EPA had unlawfully issued 59 pesticide registrations between 2007 and 2012 for a wide variety of uses.
- The more recent theory of bee colony collapse disorder is various pesticides, including neonicotinoids, harm the bees' immune system and allow infections of fungus and mite infestations on the bees, which eventually kills multiple hives. Hobby bee keepers have also reported large bee deaths when their hives are near a farmer's field.
- Neonics., as they are often called, can be sprayed on plants, and their flowers, and when bees touch the flowers the pesticide gets on them.

1985 memo: Monsanto suspected glyphosate caused cancer
Twitter pic.
The letter is as follows:
April 3, 1985
To: T. F. Evans
The following item of information is in addition to those included in the current monthly report.
Senior management at EPA is reviewing a proposal to classify glyphosate as a class C "possible human carcinogen" because of kidney adenonomas in male mice. Dr. Marvin Kuschner will review kidney sections and present his evaluation of them to EPA in an effort to persuade the agency that the observed tumors are not related to glyphosate.

El Salvador bans Roundup and gets record harvest!
- In September 2013, El Salvador passed a ban on 53 crop protection products for agricultural use. Among them, the large coffee, cotton, maize and sugarcane producing country was pulling off Roundup (glyphosate), a Monsanto star herbicide, recently listed as a "probable carcinogen" by the World Health Organization (WHO).
- GMO seeds cannot be saved from old crops, they must be purchased every year, leading to an increased cost for the farmers.
- The GMO seeds were not adapted to the locality.
- They are using H-29 maize instead.
