[SIZE="4"]On a string – generating electricity with a kite [/SIZE]

Kites can climb up to altitudes kilometers higher than the vanes of wind turbines. As they pull on their tethers, they create forces that can be used to generate electricity. A system of spools and winches could then be used to power an electrical generator. Yet this vision can only be realized if the kites are both strong and light.

I was about to post a question on how my electric toothbrush charges when it doesn't have any metal contacts with its cradle. Eto na pala yung sagot:

Power pads
Another type of wireless electricity technology can send large amounts of power over very small distances, often not more than a few centimeters.
Such technology is available today, but only in minimal ways. Think, for instance, about electric toothbrushes that sit on charging cradles but don't actually plug in.

Power tools need this technology.

I remember tripping over power cables during my short stint doing carpentry.

wireless electricity sounds scary... lol

though di pa ma prove yung cellphone signal delikado... medyo ok pa pakingan... but a power to light a 220v bulb wireless?

why not invent something like a bulb that is 1watt and 1volt... mas ok pa pakingan. haha...

induction charging ang tawag dito. eto ang link sa wikipedia, http://en.wikipedia.org/wiki/Inductive_charging

yan ang next e-revolution sa celfon charging, lalu n sa next gen Ipod ( sabi daw).
