minus-square dom ( @dom@lemmy.ca ) linkfedilink33•1 year agoPeople think the cost of the panel is the most expensive, but it’s actually the 151 million km copper cable
minus-square FZDC ( @FZDC@beehaw.org ) linkfedilink16•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-square dom ( @dom@lemmy.ca ) linkfedilink11•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-square jarfil ( @jarfil@beehaw.org ) linkfedilink13•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.
