Homemade Solar Cell Built Right In Your KitchenS

With The Man jacking up energy prices, it's probably not a bad idea to start investigating the benefits of solar power. (No, nobody cares about energy derived from the wind, Netherlands, thank you very much.) The solar panel in question is made from cuprous oxide rather than the usual silicon. Science Toys has the step-by-step instructions on how you can turn a trip to the local hardware store into a fun afternoon building a device capable of delivering a whopping 12.5 microwatts of power. Isn't learning fun?

Admittedly, this is more of a proof-of-concept than anything else since you probably won't even be able to power light bulbs or anything, but soon enough we'll be able to build bigger cells with bigger solar panels until we make a cell so large it will destroy us all. (Or something to that effect.)
