No more plugs and wires?

June 8, 2007

Laptops that recharge themselves? Toasters without wires? Light bulbs that light up without being plugged into a wall? Sounds like a haunted house! But, no, it’ll soon be our reality.

Drudge Report links to an article about a new invention: sending electrical power through the air instead of via wires. It’s been possible for a long time to send electrical currents through the air, but only via very short distances via electromagnetic induction. But scientists have figured out a way to send electrical power through at least 9 feet — and this would be ideal for recharging batteries used by bulbs, laptops, etc.

This technology may be called “WiTricity” (much like “WiFi” used for high-speed Internet browsing by computers and handhelds). Stay tuned — hope we’ll get this in our homes soon!

    It looked great idea! Will it be possible harmful to body by electric radioactivie? It may lead to lose hairs, develop cancer to body? Or safety proof?

    The article says that apparently it’s totally safe — that “there is little to worry about on safety grounds, saying that magnetic fields interact weakly with living organisms and are unlikely to have any serious side effects.” Hmm, “unlikely” isn’t too reassuring …

    I would love to have it in our house!! but yeah need to check to be sure there is “NO little to worry…”
