I've always wondered why we use wind and solar cells, make electricity and try to store the energy in expensive batteries. Why not use wind power to power a heat pump, make hot and cold water with the freon? Cold water for cooling and hot water to heat.
Wind farms have a big problem getting the electricity from where it's generated to the big city. Seems power companies don't want to share power grids. Is it possible to use the electricity from wind farms, convert water in to hydrogen and oxygen? Hydrogen could be used to power cars using fuel cells or burn it like gas. Hydrogen pound for pound has about 2.5 times the energy of other fuels. Have a feeling that's why NASA used it.
I'm sure the green people would like hydrogen. When you burn hydrogen the exhaust is water.
