i saw a program on dicovery channel which was discovery project planet earth
they had the idea of sending a huge solar panels to space and they would collect the energy from the sun and then beam down the electricity to recievers using microwaves. they did it on small scale and it worked!!
can any one explain me how can we beam electricity using microwaves?

That's actually fairly easy.

When you boil water in a microwave over, you are transmitting energy
from the feedhorn in the over to the water, using microwaves.

When you listen to a crystal radio, you are receiving energy transmitted
to you over radio waves.

Solar Power Satellites would use large antenna farms in the desert to collect
microwave energy beamed down. This would be converted to AC current in
transmission towers and sent to your house.
