Twirling Battery Provides Instant Energy for a Dead Cellphone
- ars 17y agoCute, but twirling is not really the best way to harvest energy from a human. Even if your goal is a really really small generator.
- radu_floricica 17y agoIt would probably be more effective to twirl the phone too. Easier, less space taken by the ring. You just need a system that makes sure you won't drop the phone by mistake.
