Any one out there care to try this? The UK’s Register Hardware this week features a video in which Blake Farrow, a US “boffin” (for “eggead”), as they describe him, shows how to make a working solar cell using such odd ingredients as powdered donuts, Starbucks tea, a pencil, cellophane tape and Everclear. It might sound crazy at first, but the science behind it seems pretty sound … and Farrow actually demonstrates at the end how the offbeat device generates real electricity.
You can check out the fascinating and entertaining video here.

Oy, I’m not american, eh! Just a visitor from the cold north.
hmm… microamps… Interesting, but this type of solar cell has been around for a while. Considering cost/time/effort/performance it is probably a lot easier to just buy a cheap surplus cell. But perhaps this is useful to motivate the children…
