Technology Review: Wireless Power Harvesting for Cell Phones

 

Should we start a book on when a working prototype gets developed?

why not stick the gyros like you get in watches into the phones? then when i walk it charges.

i was about to suggest that kinetec charging i believe its called so as it moves round in your pocket/you move it adds to the charge probably not going to keep it fully charged but should prolong battery life

I think that the phones and devices of the future should integrate all sorts of power harvesting technology. Gyros for motion energy, solar absorbant materials (http://www.treehugger.com/files/2007/04/new_zealand_solar.php) for the cases, wireless signal power harvesting and high efficiency Seebeck effect [ame]http://en.wikipedia.org/wiki/Thermoelectric_effect[/ame] harvesting for temperature.

 

All of these technologies exist today and with the possible addition of new antennas and transmitters based on synchotron research (Table-top Synchrotron Defies Convention) they could also use far less power than they require now to emit a signal recivable by satelitte base stations rather than the more conventianal and numerous ground based units.

Not self-charging, but a step in that direction...

Possibly due to the much higher power requirements of a phone it wouldn't make any difference. It would probably last minutes longer. Newer phones are a lot more power hungry, especially with touch screen as of course the screen has to be fully illuminated.
