Crowdfunded 'PowerWatch' Runs on Body Heat, Never Needs Charging (engadget.com)

Engadget reports on a new watch that suggests the possibility of a future without chargers: This thermal-powered wearable doesn't need one -- it gets energy by converting your body heat into electricity. It's been a year since I saw an early prototype of the PowerWatch -- a smart(ish) watch that tracks basic fitness metrics. Now, the self-proclaimed energy-harvesting company is finally ready to ship PowerWatches to the early adopters who backed its Indiegogo campaign...

Because its functions are pretty basic and its LCD screen is relatively low-powered, it doesn't take too much electricity to keep the watch running... The PowerWatch can not only tell the time, set alarms and timers but also track your activity and sleep... Matrix co-founder Douglas Tham said the PowerWatch will keep running for up to 12 months if you don't wear it, and a PowerSave mode kicks in to conserve energy by killing non-timekeeping functions.

Not what was promised

When this first came out, the makers promised a fully fledged smart watch. Now this thing could easily be powered for 5-10 years with a button cell and many âoeregularâ models like it have existed for at least a decade.

Watch the thing dying on everyone after 13 months, right outside the warranty.
