    Argh I hate how they never show installation costs upfront…

      People think the cost of the panel is the most expensive, but it’s actually the 151 million km copper cable

        Why can’t we just wirelessly transmit the power, maybe have it hit a collection device that can harness about 4 kwh/m^2/day

          Hey that’s not a bad idea. We could install these receivers on people’s roofs or in big parking lots

        Copper 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
