Good news for the developing world. If you can’t afford Fusion in the coming decades, how about Potato Powered Batteries!

From the creator’s press release:

“Cost analyses showed that the treated potato battery generates energy, which is five to 50 folds cheaper than commercially available 1.5 Volt D cells and Energizer E91 cells, respectively. The clean light powered by this green battery is also at least 6 times more economical than kerosene lamps often used in the developing world.”
