minus-squaredom@lemmy.calinkfedilinkarrow-up32·1 year agoPeople think the cost of the panel is the most expensive, but it’s actually the 151 million km copper cable
minus-squareFZDC@beehaw.orglinkfedilinkarrow-up16·1 year agoWhy can’t we just wirelessly transmit the power, maybe have it hit a collection device that can harness about 4 kwh/m^2/day
minus-squaredom@lemmy.calinkfedilinkarrow-up10·edit-21 year agoHey that’s not a bad idea. We could install these receivers on people’s roofs or in big parking lots
minus-squarejarfil@beehaw.orglinkfedilinkarrow-up13·1 year agoCopper wouldn’t cut it, too much resistance. You need a superconductor… only problem is how to keep it cold enough at below 1000C.
minus-squareredcalcium@lemmy.institutelinkfedilinkarrow-up10·1 year agoEasy, just cool it with some sort of space refrigerator. Solar powered of course. Net electricity arrived on earth after cooling cost: 1kwh/day
