Old meets new in surprising ways. From the Japan Times: Power for All the People
Fujimura has rigged up a ¥50,000 machine to refurbish the discarded car batteries that litter the Mongolian steppes. The batteries can then be fixed to a small cart that's pulled behind a galloping horse, turning a generator that recharges them. Fujimura says a two-hour sprint provides enough energy to light a yurt and power a small TV for one week.
Granted, it's not electricity-free technology, but it does no environmental harm, turns garbage into a resource — and may help make nomadic life a more attractive option for the 21st century.
