China is making quick changes to clean energy and investing considerable time and talent in new researches for green energy. Because they weren't aware of the ill effects of the use of fossil fuels, but now are beginning to pay attention to the environmental effects of the poisonous gases. So now china is working on a new type of internal combustion engines. They are also using new and more accurate computer models to assess the performance of the free-piston linear alternator.
