C Scientists have figured out how to make large amounts of oil from duckweed (浮 ).Processing such plant oils into biodiesel(生物柴油) for transportation and heating could be a big part of a future looking for clean energy. Researchers could use duckweed plants to produce seven times more oi...
When your car is driving on the freeway, about 4-7 percent of its potential energy is lost to the rolling resistance of the tires. Tires bend and deform a lot as they roll, which uses a lot of energy. The amount of energy used by the tires is proportional to the weight that is ...
This process is called co-generation of heat and power (CHP) and it improves the overall efficiency of the system. Alkaline Fuel Cell (AFC) This is one of the oldest designs for fuel cells; this type was the first the United States space program used to produce electricity and drinkable ...
