Holey graphene might make better batteries

At Northwestern University, engineers have made a new type of graphene* electrode: one punched with many microscopic holes. It could store 10x as much power (30,000mah instead of 3000) and charge 10x faster. As with any new technology, a big problem is to make it cheap enough for consumers to buy.

* Graphene is a single layer of carbon atoms, usually on a substrate.

Monsanto faces more new cancer lawsuits

Monsanto is facing more lawsuits, and a bundle of 3 lawsuits was filed in St. Louis recently. The claim is glyphosate exposure caused them to get non-Hodgkins lymphoma, for which there is some correlation to glyphosate exposure.

This graph of correlation shows how closely the studies found glyphosate exposure was related to certain illnesses. Non-Hodgkins lymphoma was the most correlated.

Joule Thief circuits

A Joule Thief is a circuit that can boost voltage. It can be useful to make LED flashlights, or for emergencies, where you only have a single 1.5vdc battery. The Joule Thief (JT) can be used to boost the 1.5vdc to 3.0vdc or more. All the parts can be bought at Radio Shack, or Ebay.

The below Joule Thief is very efficient. It can be made from simple parts and is powered by one AA battery (or any 1.5v battery).
This Joule Thief needs 0.4v-1.5vdc as input. You will have to make your own custom toroid though.
Below is another simple JT circuit.

DIY batteries and choosing an electrolyte

When making DIY batteries, which electrolyte should we use? It should be easily found in stores, inexpensive, and fairly safe. But which liquid electrolyte works best? 
The best electrolyte we found was hydrogen peroxide + table salt. Hydrogen peroxide is available at drug stores and safe to use, but we suspect the solution has to be made up fresh -- it won't keep.

Another battery they talk about uses 2 different electrolytes:
copper metal | copper sulfate solution | salt solution | zinc metal

This uses 2 different paper layers soaked in each electrolyte: copper sulfate and a salt solution. The problems with this is the paper would eventually dry out unless it is in a sealed container. Putting shrink tubing around a penny and zinc battery might help.

But ethanol, ammonia, vinegar, sulfuric acide, and muriatic acid can also be used. But saltwater can be very harsh on certain metals like magnesium.

By looking for a "galvanic potential" chart we can see that aluminum and graphite in a solution of hydrogen peroxide and salt can work well, but the hydrogen peroxide will not last long, especially if exposed to light.

Broken energy meters report up to 600% more energy used than actually used

A new study by the University of Twente in Holland shows many meters can give inaccurate readings, in some cases showing up to 582% more energy used than was actually used. The most problematic meters are the newer digital "smart" meters. Older meters with a rotating disk are more accurate.

Monsanto defeated re: PCBs

PCBs are highly toxic to people and the environment, and Monsanto has been dodging lawsuits for decades. PCBs were banned by the EPA in 1979. Various cities, like Portland, and even Washington state, want Monsanto to pay for cleanup costs. Monsanto didn't want to be responsible for chemicals it no longer manufactures. Monsanto requested a judge for a motion to dismiss lawsuits but the motion was denied, and the lawsuits continue.

Farmers know how dangerous dicamba is

Highlights: 
  1. Dicamba use will expand a lot in 2017.
  2. Make sure to wash dicamba tanks REALLY well. Not doing so can result in crop damage and legal problems.
  3. A triple rinse is advised.
  4. Damage from that chemical "shows up at much lower levels" than some other herbicides, said Fred Whitford, a professor in Purdue University's pesticide program
  5. Disposing of rinse water can be tricky as even small amounts of dicamba are dangerous.

Food additive might be linked to stomach and several other problems.


Researchers at Binghamton University in New York found that chronic exposure to titanium dioxide — an additive present in chewing gum, candy and bread — changed digestive cells’ structure and function. Ultimately, the study suggests that frequent consumption of foods with the additive may lead to less nutrient absorption, impaired digestive function and a slower metabolism. Chronic exposure also led to more inflammation, an effect that is tied to chronic diseases such as cancer and heart disease.

Is Power over Ethernet cable the next big thing?

New CREE light fixtures (not just bulbs, fixtures) use power from ethernet cables. They can also be controlled by the computer over the network. It looks like a special router just for these lights is needed.

There are several levels of PoE:
  1. PoE (IEEE 802.3af) provides up to 13 W (37 to 57 V, max 350 mA).
  2. PoE+ (802.3at) bumps it up to 25 W (42 to 57 V, max 600 mA), but requires Cat5 cabling or better. (If each LED draws 3.3vdc then PoE+ port can support up to 7 of those LEDs. The volts drawn by each LED seems to be the limiting factor, not the amps.)
  3. UPoE: 60vdc limit but at how many amps?

Self-charging battery from Phys.org

Usually 2 separate units are used to generate and store energy. 1. Something to generate the energy, like solar, coal, gas, etc. 2. A battery to store the energy. Now for the first time, using nanomaterials, a self-charging battery has been made.

They used a PVDF film, which is a piezoelectric material. That means when it's compressed, it generates a small amount of electricity. This is how many cigarette and barbecue lighters work. You have to press that "ignite" button pretty hard to make a spring-loaded hammer smack a piezoelectric material, to generate that spark.

A compressive force at 2.3Hz could generate 327 to 395 millivolts. While that is not enough to power an LED, which requires about 2200mv, that voltage can be boosted somewhat. This important because it creates energy from mechanical movement in one step.

A compressive force with a frequency of 2.3 Hz could increase the voltage of the device from 327 to 395 mV in 4 minutes.

GMOFreeUSA testing foods for glyphosate

GMOFreeUSA is testing foods in the US for GMO content along with glyphosate. This program is called Operation Label GMO. In the future they also want to test 2,4-D, dicamba, atrazine, and neonicotinoid insecticides. A combination of these toxic chemicals is likely responsible for lots of bee deaths around the US. The chemicals overwhelm their immune system, and they can get fungal or mite infections, and die. These infections then spread to the rest of the hive and can wipe out most of the hive. Commercial bee keepers, who help pollinate many of the US crops, are very concerned.

Sunchips and Gerber Lil Crunchies have already been found to contain pesticides by GMO Free USA. So have Cheerios, Doritos, Goldfish crackers, Oreos, and Ritz crackers (source).

Second class action lawsuit against Monsanto for dicamba damage

2/16/2017

A new class action lawsuit against Monsanto, in US district court in Missouri, is about damage from dicamba. Even small amounts of dicamba are dangerous to crops, and can directions advise triple rinsing dicamba tanks and carefully disposing of rinse water. Even spray that drifts from one property to another can kill many crops costing the farmers a lot of money.

Monsanto's Xtend cotton and soybeans are resistant to dicamba, and so farmers spray them to control weeds. But spray drift can kill neighboring farmers' crops.

A Missouri bill wants to stop illegal dicamba use. And farmers must be careful about spraying in windy conditions.

Research continues on non-exploding lithium batteries

Researchers at Tufts University continue to develop their lithium battery that does not explode or catch fire or even heat up when punctured or cut. Prof. Zimmerman does not use an electrolyte and instead uses a plastic barrier between the anode and cathode. This could be a great leap in safety, and storage capacity, for lithium batteries. But can they scale up production?

There was even a Nova show (Search for the Super Battery) with Prof. Zimmerman.

Low levels of Roundup cause liver disease in rats

A long-term, low-dose study by Seralini and others shows Roundup causes liver disease in female rats. The study took 2 years and...
The dose selected was below what people are commonly exposed to in the everyday environment and 75,000 times below what is permitted by EU regulators.
The study found Non-Alcoholic Fatty Liver Disease in the rates. NAFLD is found in 20% of the general population today, making people wonder if there's a link between Roundup (which contains more chemicals than just glyphosate) and NAFLD. Naturally, a study was warranted. In a previous study, even rats given 0.1ppb (parts per billion!) over 2 years showed liver damage. In the current study, 214 proteins out of 1906 were "disturbed". That's 11.2%. But hundreds of proteins being disrupted is still very bad.

Thin film cell generates 6vdc.

This cell is no more than 1mm thick and about 2x2 inches. It generates 6vdc. I'd like to figure out how to make one to test how many amps it has.

This guy has been doing a lot of work over a year and he might be on to something if he can scale up production.

Youtube.

He also has a prototype called  mini generator. He uses a silicon graphite cell but with a slightly different electrolyte. These are not capacitors, they are generators that make their own electricity. The voltage is 3.5-v4dc, good enough to power 1-2 LED lights, or more with a voltage booster. Magnets are used to compress the layers to increase efficiency, but if he uses neodymium magnets the cost could go up to $10usd for the one cell he displays in this video. NDs are not cheap.

Radioactivity spreads over Europe

No one can figure out where the radioactive Iodine-131 comes from. Wikipedia says:
It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production. It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Fukushima nuclear crisis.
It was first found near the Norway Russia border in January 2017. Perhaps there is a nuclear site near there. It also appeared in Finland, Poland, Czechia (Czech Republic), Germany, France and Spain but details of the problem were only release recently.

DIY Magnesium, graphite, and salt water battery

Here's a Youtube video about making a DIY battery from magnesium, graphite, and salt water as the electrolyte.

  1. I got magnesium ribbon from Ebay. 
  2. Graphite is what's in most US pencils these days, it's not actually lead, the metal. So carefully cut away the wood from a pencil, and you are left with a graphite core. 
  3. Any saltwater solution can be made. You can start with a weak one: 100ml water, 1tsp salt. Take a voltage reading with a multimeter. 
  4. Add another 1tsp of salt and stir well. Take another voltage reading. 

  • How good is this battery compared to other DIY batteries in this series? 
  • What if you change the electrolyte to vinegar? Lemon juice? Soda? Do the volts go up or down?

India: spinach from Hyderabad contains pesticides

Spinach can be good for you, if it doesn't contain pesticides.

A survey by some research scholars of Jayashankar Agricultural University revealed this startling reality after testing the samples secured from Rythu bazaars in Mehdipatnam, Gudimalkapur and Shamshabad. The survey found that the leaf vegetable contains 11 types of pesticides, including five commonly used, like chlorpyrifos, triazophos, cypermethrin, deltamethrin and profenofos, Dr Narasimha Reddy, a scientist of Pesticide Action Networks India told The Hans India. He said the pesticides were found to have been sprinkled on the leaves of the vegetable to prolong its longevity post-harvest, after cutting.
Pesticides are in more foods than you think, which is why it's time to have a portable pesticide detector for consumers to check all food. Not all organic food is pesticide- or gmo-free.

Lantern receives free data 24/7

The Lantern device from Outernet receives data for free from their collection of L-band satellites.
  • It is solar charged. Battery holds 4000mah.
  • It receives 20mb per day. That's about 20 minutes of good quality audio, average quality video, or 40 minutes of mono audio.
  • It does data to the internet, communication is receive only. 
  • A DIY receiver kit is $100.  It comes with the CHIP single board computer. (This means it requires a monitor, keyboard, mouse.)
  • It saves data and becomes a wifi hotspot, so you can share data with others. 
  • It currently receives content from offline Wikipedia files, and news stations like BBC, Medline, WHO and Al Jazeera. 
  • It has a USB for output, an SD card slot.  
  • You need to install an Oracle VM in order to update the hardware for Skylark.
  • The CHIP computer uses the OS called rxOS. 
From Wikipedia:
The Outernet broadcast is broken into three categories: the Queue, Sponsored Content, and the Core Archive.[5] Content in the Queue is decided via votes on Whiteboard as well as requests via the Outernet Facebook page. Outernet plans to expand the avenues through which it is able to receive requests for content. Anyone can view what is being broadcast on Outernet at any time.

  2. How can I request a specific file, ebook, or video? Use their Whiteboard, as a way to suggest content.Or their Filecast Center.
  3. Is the hotspot secured with a password that I can give to other people?  
  4. For the hotspot, is there user-level security where some people can access only one or two folders? 
  5. Can it connect to a Windows PC via wifi or USB port? Or do I need a separate keyboard, mouse and monitor? 
  6. How can I remove and manage content on my own Lantern hotspot? 
  7. Can I name the hotspot? Does it need it's own IP address? How do I get an IP address?  
  8. Can I leave it out in the rain? What about the snow?  A plastic enclosure is due soon.
  9. The DIY weather kit is not weather-proof. Are there any cases for the receiver?  
  10. How do we point the receiver to make sure we get the strongest signal?
  11. It uses a battery pack for power, but can it use 5vdc connected to mains power?

DIY AA battery delivers 1.6vdc!

Yes I'm Jonesing for DIY batteries! There will be several articles on different types of DIY batteries.

This is a neat DIY project even kids can do. The voltage is so low it will hurt no one.


This delivers 1.6vdc. It probably costs more than batteries at the Dollar Tree, but it will work in a pinch. All you need is galvanized washers (which provides the zinc layer) and copper washes (for the copper layer), and cardboard soaked in vinegar or another acidic solution, or salt water.

An AA battery has a diameter of .53" (14mm) and a length of 1.95" (49.7mm) including the top button. If fitting this into a device is important, try to get 13mm washers (outside diameter) so you will room for the shrink wrap. A US penny can be used but it's too wide at 18.9mm.

Modern US pennies since about 1984 have a zinc inside, and thin copper layer outside. So you can sand off one side of the penny to expose the zinc, and the other side will be copper.


Some questions to ask when making this:
  1. Does the voltage or amps produced depend on the surface area of the washers? 
  2. What happens to the volts or amps if you change the electrolytes? 
Copper washers.
  1. Copper washers, 10x, from Hong Kong.
  2. Assorted copper washers various sizes, 200 pcs
  3. Copper washers, 6mm inside diam, 10mm outside diam, 1mm thick. 10 pcs.
  4. Copper washers, 14mm outside diam, 10pcs.  
  5. Copper washers, 13mm outside diam, 10pcs.

Zinc washers. (Galvanized washers means they are coated with zinc to resist rust.)
In various metric sizes.

Misc
  1. Washer dimensions.
  2. More metric washer dimensions (PDF).
  3. M6 washers have an OUTSIDE diameter of 11.5-16mm.

Study shows Roundup causes liver disease

Keep in mind that there's a difference between glyphosate (which is bad enough) and Roundup, which contains surfactants to make it better absorbed by plants. Some studies indicate Roundup to be much more dangerous than plain glyphosate.

The study was peer reviewed at Nature.comdoi:10.1038/srep39328
The impairment of liver function by low environmentally relevant doses of glyphosate-based herbicides (GBH) is still a debatable and unresolved matter. Previously we have shown that rats administered for 2 years with 0.1 ppb (50 ng/L glyphosate equivalent dilution; 4 ng/kg body weight/day daily intake) of a Roundup GBH formulation showed signs of enhanced liver injury as indicated by anatomorphological, blood/urine biochemical changes and transcriptome profiling. 
Wow! Damage at parts per billion! Or 4 NANOgrams per kg of body weight! Damage occurs at concentrations far below EPA standards.

This was a 2 year study on female rat liver tissue.  The rats suffered from Non-Alcoholic Fatty Liver Disease (NAFLD). NAFLD currently affects 25% of the US population. NAFLD can progress to the more serious condition non-alcoholic steatohepatitis (NASH). Over the 24 months the trigliceride levels rose in the rates. See Figure 1 graph in study.

Danish study: GM soy linked to sick pigs

Don't forget about this one from 2012. Farmers are learning how huge losses are caused by GM feed. But it's not the GM feed that's the problem, it's the pesticides, especially glyphosate, sprayed on the feed. Glyphosate is a systemic chemical, it's in all parts of the plant, and it can't be washed off. Many studies show it's harmful to mammals and mammal cells.
A Danish farming newspaper has caused quite a stir by devoting a sizeable part of its 13 April edition to the discoveries by pig farmer lb Borup Pedersen that GM soy has a damaging effect both on his animals and on his farming profitability. On the front page of the paper there was a lead story under the headline "Pig farmer reaps gains from GMO-free soy". On a sidebar the paper referred to Mr Pedersen's contention that DDT and Thalidomide were minor problems when set alongside GMOs and Glyphosate. In an Editorial Comment on page 2, the paper argued that it would be grossly irresponsible for the authorities to ignore or ridicule the discoveries made by the farmer in his pig farming operations, and it congratulated the authorities for commissioning a new study designed to determine whether stomach lesions and other effects might be associated with GM soy; in the study 100 animals will be fed with non-GM soy and 100 with GM soy in their diets.
Mr. Borup Pederson talked to a mainstream Danish farming newspaper (Effektivt Landbrug).


In his discussions with GM-Free Cymru Mr Pedersen itemised the following effects:
  1. Within 2 days diarrhoea virtually disappeared in the farrowing house, whereas before we had used 50-100 ml Borgal / day.
  2. Since switching, we have not experienced death from bloat in sows or death by ulcers, as opposed to minimum 1 per month previously. (36 sows died due to stomach related sickness over the last two years before switching)
  3. No sows have died through loss of appetite, whereas 2 sows died from this cause last year.
  4. Even without washing between farrowings, diarrhoea does not now reappear. Previously when we failed to wash between sows, we noticed more diarrhoea.
  5. Previously we have struggled with diarrhoea in first layer sows, we do not have this problem any more!
  6. Two years ago when the diarrhoea was as its worst, we had months with nearly 30% dead in the farrowing house. At that time it was impossible to find sows that could nurse piglets.
  7. Before it was unusual to have a sow with 13 piglets weaned. The average was about 10.5 per sow plus spare mothers. Now we are getting over 12 piglets on average weaned and 14 piglets weaned per sow is common. We have fewer nursing sows, simply because the sows are milking better and eating more.
  8. Sows farrow better and we have 0.3 more live births per sow, of which 0.2 is gained from fewer stillborn. Now we have 14.9 liveborn and 1.6 stillborn, averaged over the past 7 months.
  9. The piglets weaned are stronger and more evenly sized.
  10. Man-hours are reduced by 20-30 hours per month, partly by washing less and because everything is easier.
 This isn't a full-blown study, but still, it's very telling and should point the way to a larger study.

Batteroo post updated

The Batteroo post has been updated as people test the device. Read up here.

Basically I thought it was possible to miniaturize a Joule Thief but this device doesn't even do that. It's a total scam.

Testing different electrolytes at home for DIY batteries.

For each DIY battery you make, you have dissimilar metals, like copper and zinc. But sometimes they are not always metal, like the aluminum foil and activated charcoal battery. In order to test the power output of different electrolytes we must make all other variables the same. Here's what you will need:
  1. Penny
  2. Nickel, post-1964 (1964 was a transition year so some nickels contain silver, get a nickel post-1964 to make sure it has no silver)
  3. 2 wires each with an alligator clip.
  4. Multimeter. If you want to use a USB meter instead you will need to buy this USB to test hook adapter.
  5. 3 beakers or glasses. Plastic cups can work also. 
  6. Salt
  7. Vinegar
  8. Lemon juice
  9. Measuring spoon of 1 teaspoon
  10. Measuring beaker of 100ml. If you don't have a beaker use a measuring cup for liquid measurements, not dry measurements.

Above: I use different containers, and I found a 60ml measuring cup!
Above: Find some wires with alligator clips on both ends. Hook the red wire to the nickel (+, red) and the black wire to the penny (-, black).

Now put 100ml in a glass, put both the penny and nickel in the water, and turn the multimeter to measure DC voltage. We get about 147millivolts with plain water, that's not enough to even light an LED.

Remove the penny and nickel. Now take the 100ml of water and add one level teaspoon of salt to it. Stir it well. Now put the penny and nickel back into the water. What voltage does the voltmeter read now?

If your multimeter reads a negative voltage it just means you have to switch the probes around. A negative voltage won't harm your multimeter. 

Remove the nickel and penny and add a second teaspoon of salt, stir it well. Put the nickel and penny back into the saltwater. How much voltage is being generated? How many amps?

Discard the salt water and rinse the glass well. Now make these solutions and test the voltage and amps they output. Write each result down.
  1. 50ml water, 50ml vinegar. 
  2. 50ml water, 100ml vinegar. 
  3. Discard vinegar water and rinse glass well. 
  4. 50ml water, 50ml lemon juice. 
  5. Discard lemon water and rinse glass well. 
  6. Add 100ml of soda. Take a voltage reading. Write it down.

What happens to the voltage and amps in each case? By adding more vinegar or lemon juice (both acids), does the voltage go up or down? What kind of voltage does soda give? Sodas are very acidic so they should work very well.

Summary
You can search the internet for different kinds of metals. Certain combinations of metals give higher voltages, and some give more amps, and some give a longer run time. Likewise, the stronger acids can also have an effect on voltage.

"I'm not dead yet!"

"I'm not dead yet!" said a plague victim in Monty Python. Well, we're not dead yet either, we're just busy. If you have an article to submit, please write it up and get in contact with me to have it posted.

Thank you and have a great new year!
