  • Using old laptop batteries to build homemade powerwalls

    UHVDC is something like 800kV. DC is much less workable at low voltages like 12v or 5v common in household application -- the P=IV equation is more dominated by current, so with more current the resistive losses add up quickly even in a run across your house (itll be down to 10 or 8v by the time the wire reaches the far end of your house).
