Shiny stainless steel window sills on the inside of the house. When the sun shines in. They heat up and radiate heat. Inside the house. The warmth radiated wouldn’t be that much. But some.
The sun-facing exterior of a building could be clad with a passive solar collection system such as black tubes enclosed in a translucent casing. In winter, a solar-powered fan at the bottom could draw in cool air and circulate the hot air at the top back into the building. In summer, the hot air could potentially drive a turbine to generate power to cool the building.

Have solar panels on the roof of the car collecting and storing energy to help when the car is plugged in to recharge. It would save some of the energy in recharging.
I have an idea for creating steam power with magnifying glass heating water pipe to create steam to run generators. Has anyone done this yet?
