Solar power

They say the future is solar power. Well, I did not see that in remote viewing. A time trip to 2052 shows a world with tiny car. They do not use electricity, but run on gas. Hate to break it to you. Fossil fuel will be around a long time and then some. People wonder how solar power derives its energy. Well, the photovoltaic cell convert sunlight into electricity (DC) which is stored in a battery and from there it goes to an inverter that generates 120V AC for you. Problems are many. This is an inefficient process. Solar cells are very expensive. Batteries are good for about 200 cycles and they are also expensive. Basically, the cost of each kilowatt of power using solar is a lot more.
