#1) I LOVE the idea. Freeplay demonstrates the innovation that only a Free Enterprise system of economics can achieve.
#2) In ANY battery technology, you are working against the 2nd Law of Thermodynamics--or what most scientists simply call The Law.
STORING energy is extraordinarily difficult, which is why petroleum was such a God-send to the western world after whale oil as it stores potential energy so well.
Battery tech, currently, must fail vs active, petroleum-based energy.
i have one of these wind up freeplay chargers and they work very well for charging up devices , and yes its only used for an emergency as you have to crank hard and fast to get the 12 volts that is needed to charge the device
I noticed you showed the winding for a few seconds only and with no sound. I know why; there is no way to wind in a more or less continuous way. I bought one and it's a nice gadget. The winding is EXTREMELY hard though. For an emergency I would recommend the freeplay weza.
