DC for your home?

looking at several DC/AC converters etc i think one should generate DC power with solar panels, store it as DC, and use it as DC

every half-way decent and affordable converter comes only with some 80-90% efficiency, and the waste is always heat! that’s ok in winter, but realistically: who will heat their water or room with that heat?

one could easily have their A/C rebuilt using a DC motor, use DC for lighting with LED lights, install a DC outlet for the computers etc – apparently a regular PC powersupply can work with a (higher voltage) DC input as they are right now, even without any changes! (got to verify that though)
