Review of Ebay Solar panels

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.
