It's time for power beaming in wireless electronics

Bob Russell · 09-28-2005, 07:25 PM

There's an excellent article at Mobile Pipeline that has a lot of information about energy harvesting and beaming power wirelessly.

"Today’s much touted wireless gadgets could be more properly called wireless 'communication' devices since, at some point, a wire is still needed to convey power from the wall to the appliance. On the other hand, hundreds of kilowatts (kW) of power have been successfully transmitted wirelessly across long distances for quite some time. While the focus of wireless power transmission has been so far in the megawatts (MW) , such as in solar energy harvesting or milliwatts (mW)as in RFID (Radio Frequency Identification), the time should be ripe for porting this technology into many different portable wireless applications."

I just hope that my internal organs don't become the receiver! Read the full article here.

Remember Slashpower? It's also about wireless power recharging, though not over long distances as suggested in your article, Bob.
