Cheap and renewable energy

Coal power plants are the cheapest energy producers (0.05 – 0.08 US dollar/kwh) but they produce the largest quantity of the global warming gas, CO2. Solar energy plants are the cleanest but their cost of investment is very high (2,500 – 3,500 US dollar/kw). Electrical energy is the best form of energy for the industry but storing big amounts through long times is insolvable at a low price.

The combination of our solar energy plant patents with our coal producing patents gives a really cheap and renewable solution and solves the problem of the unlimited time storing of the energy.
