I like this, although I'm more of a modular guy than a monolithic guy and would prefer to see the means of power generation separated from its storage.

I believe that an interesting corollary to devices which have become increasingly efficient in terms of power consumption and increasingly mobile in terms of usage scenarios will be that the means of generating power for them will become increasingly manual and simple. For example, I'm a big proponent of gyroscopic hand and wrist exercisers for anybody who uses a computer on a daily basis. These can be found under a few different brands, and I'm aware of (but have neither tried nor even heard many first-hand accounts about) an adaption of these called “manual power” which translates the spinning of the internal rotor into electricity that be made to power devices over an attached USB connection. I believe that Freeplay also has similarly portable, manual power generators to quench our little gadgets.

It seems logical that if you're functionally dependent on your mobile technology then you should have your own means to generate power for it. I'll stop short of calling that logic a “no brainer” because it would imply that almost nobody actually has a brain.

People in an earth quake prone areas will never have to worry about a dead battery?

Perhaps those who use the virbrator exercise devise could also be recharging their batteries by using these new one?
