Buzz, it sounds good but until it's cheap enough the average Joe won't buy into it.. Currently with the power wall battery you require a solar system still and inverters etc.. The cost per kW is still too high... Maybe in the future if its adopted worldwide... But holly crap batman, if EV and Hydrogen fuel cell vehicles take off aswell, where is all the extra nickel going to come from? That will increase nickel price which will then increase costs it's a double edge sword. Until the nickel industry finds many new resources, it may get interesting there...
