I had a strange weird idea about all this, you might not be able to generate enough power to do mechanical stuff, but I wonder if you could power nano-robots and micro power bio-telemetry gadgets using this? The problem with magnetic fields is the area of the pickup coil of something the size of a blood cell is so small.

You couldn't do anything bulk physical, but you might safely generate enough power to do ultra low power telemetry. Like hold this piece of natural granite to activate the glucose monitor sensors in your hand's blood vessels walls or something.

Or using a really good switching power supply like design you could eat a banana, all of which are somewhat radioactive, and some sensor could very slowly charge up for an hour (or a day, or a week...) and then use all that power in a millisecond to squeak out your blood pressure to your phone.

Something good might yet come of this. Probably not this decade, maybe this century though.

If somebody at YC turns this into a startup I'll be impressed.
