Wireless energy from space

Japan has serious plans to send a solar-panel-equipped satellite into space that could wirelessly beam a gigawatt-strong stream of power down to earth and power nearly 300,000 homes.
The satellite will have a surface area of four square kilometers, and transmit power via microwave to a base station on Earth. Putting solar panels in space bypasses many of the difficulties of installing them on Earth: in orbit, there are no cloudy days, very few zoning laws, and the cold ambient temperature is ideal.
A small test model is scheduled for launch in 2015. To iron out all the kinks and get a fully functional system set up is estimated to take three decades. A major kink, presumably, is coping with the possible dangers when a 1-gigawatt microwave beam aimed at a small spot on Earth misses its target.
The $21 billion project just received major backing from Mitsubishi and designer IHI (in addition to research teams from 14 other countries).

"A major kink, presumably, is coping with the possible dangers when a 1-gigawatt microwave beam aimed at a small spot on Earth misses its target." Then somebody has toast. But it's not difficult to overcome.

this was attempted on one of the discovery channel shows and at 5 miles or so the atmosphere degraded it to much to be useful. but maybe someone came up with a new way of doing it:) solar farms above supplying power to the world would help clean up the earth at least but someone would still control the project for there own gain

Right now today using the same concepts of Black and Decker portable power station and car jump starter, you could use solar panel on ground to charge backup battery 12V, it takes a bit longer though, solar panel to a solid state protected 12V battery charger with automatic shutoff, connect the 12V battery to 120V AC Power invertor or cig lighter 12v DC power out, using the battery inline 30 amp fuse with appropriate gauge wires, connect the wireless power device such as powermat.

Technology I got for $20 at walmart similiar I've been using for over a year now to charge my ipod touch, phones, wireless bluetooth set, and other things. This thing in space it sends high amount of amplified electricity focused and at great distance sending it back down to earth is nothing it uses the same concept as the atomic clock, wireless power with the cell phone broadcast sat methods and solar cell and inductive plasma laser.

They powered home, low powered electronics such as cell phone, and instantly recharged massive 12v car batteries which powered the homes low powered appliances and lighting which upon charge 1 time lasted over 45 days.

They also send power from satelite across globe as in space the sats orbit planet can constantly recieve power more so from sun as in space and the planet on ground rotates so solar panels face weather and blackout conditions.

They already did this, and Sandia Labs has been working on the power of a star to power homes a longtime they've been able to do it for very short periods of time.

yay its a teleporter!

Focus that light better and you will burn everythig down there.
