Fascinating, and awesome for people in need, but a whole new level of battery anxiety.
I hope that it has some sort of self-charging mechanism that is entirely human-powered. You would think that they'd design it that way.
But even then, batteries and capacitors eventually go bad. So they'll still have to be replaced every few years.
I don't imagine you get enough power from a gyro to be worth the added complexity. Plus of course if you never stopped working you would need an alternate way to charge it which means you still need an external power supply even if only for emergencies.
