We could install these receivers on people's roofs or in big parking lotsCopper wouldn't cut it, too much resistance. You need a superconductor... only problem is how to keep it cold enough at below 1000C.Easy, just cool it with some sort of space refrigerator. Solar powered of course. Net electricity arrived on earth after cooling cost: 1kwh/day
