  •  Didn't MIT or someone just transmit power? (1+ / 0-)

    I thought I saw something last week about a group doing a very basic version of Tesla's dream of transmitting electricity wirelessly.

    The Cubs WILL win the World Series in '07. I'm not saying which century, though.

      Quinton, wondering if

      There is enough worry about RFI now, do you REALLY want enough potential current to run a modern technical civilization zapping between the interior of the planet and the ionosphere or something?

      Tesla thought he could make it work, and if anyone could have he probably could.  However, would it ahve been a GOOD THING?

      I have my doubts.

      Look, I want to try microwave PowerSats in Geostationary orbit.  Put receivers in deserts and beam the power down from big solar to microwave stations in high orbit.  Could I even get the superGreens to let me try that without a fight over disrupting bird migration paths and frying endangered spiders?  I doubt it.

        Flying electric generators seem a lot more practical than solar satelites.

        Why put equipment up 22236 miles (at $3000-$5000 per pound) when 3-6 miles will do the trick?   When the very turbines that generate the power can be used to hoist it aloft in the first place?  When you can assemble the equipment on the ground instead of in space?   When you can generate power for 1.4 cents per kilowatt-hour?

        Even the Audubon Society is endorsing wind power and FEG have the potential to fly above the birds.

    •  Yes, it was the type of power to... (0+ / 0-)

      charge a cell phone.  Small, but effective.

      I wonder about transmitting the type of power to runa  bus, however.

      Really, WWFSMD?

      and it puts power out there for anyone to tap into. Laws of nature get in the way of wireless power, things like the inverse square law.

      And yes Tesla did spend a lot of time on broadcast power, and claimed to be able to do so. However by that time he was also deathly afraid of pearls, declared that "There is no such thing as an electron", and apparently did not believe the ionosphere exists. Claims of his regarding his later work should be evaluated carefully, noting that many of those were never demonstrated in a fashion that allowed verification.
