Forget about kiloWatt. GigaWatt is needed, maybe TeraWatt, to make sense in the future energy market. Now try to focus GigaWatts of energy in a beam and see what it does to air. Or maybe what it does to a bird flying by :-) The security measures for microwaves is 1Watt/m2. So 1GW would require a beam with an area of 1000000000m2 to be below the security level, or a "focused beam antenna" having a diameter of 36km (equivalent to 22,5 british/american miles). Any antenna smaller than 36km requires measures to ensure that no bird or similar passes through the beam, or a change of security levels. Doing 1 TeraWatt would require an antenna with a diameter of more than 1100km. I'd really like to see the power satellite that is capable of doing that.
