As we become more and more reliant on electricity, power outages hit us harder and harder. The solution is simple: build a bicycle generator.
A magnet DC motor is spun 50 times for each revolution of the bike wheel, a home-built charge controller monitors the batteries for when to kill the charge, and a power inverter lets you take advantage of the accumulated juice. How do you prepare for when technology fails you? Use technology to prepare for the worst.
F**k it, we'll do it live!
