solar power generators
Is it technically possible to collect solar power in orbit and transmit it to earth ?
Or to build a nuclear power generator in orbit (safely) and do the same. Could enough electricity be generated and sent in this way to substantially aid our energy needs?
The advantage of doing this in orbit would be 1. 24 hour sunlight for solar?, 2. Send the mess out into space if there is a mishap re nuclear?
Yes, technically possible and it even has been done on a small scale by converting the raw electricity into a beam of microwaves. At the receiving end, the microwaves are converted back into raw electricity. On a small scale, this is used in smart RFID tags used by stores to tag pilferable items. The radio beam powers the circuit in the tag so it can transmit a reply. There is no power source in the tag itself. They deactivate the tag by causiing an overload which burns out the circuitry. The problem with large scale is one of focus of beam over large distances. The beam would have to be very strong to transmit usable power, and if the beam strayed, would cause heat damage, especially to living things, cooking them much like a microwave oven does.
