Zero emission
A zero emission engine, motor, process, or other energy source emits no waste products that pollute the environment or disrupt the climate.
Zero emission engines
Vehicles and other mobile machinery used for transport (over land, sea, air, rail) and for other uses (agricultural, mobile power generation, etc.) contribute heavily to climate change and pollution, so zero emission engines are an area of active research. These technologies almost in all cases include an
supercapacitors, and flywheel energy storage
devices.
In some cases, such as
compressed air engines, the engine may be mechanical rather than electrical. This mechanical engine is then powered by a passive energy source like compressed air, or a combustible non-polluting gas like hydrogen
.
The above engines can be used in all vehicles, from cars to boats to propeller airplanes. For boats, energy sources such as nuclear power and solar panels can also be a viable option, in addition to traditional sails and turbosails.
A concept like
vegetable oil economy
produces emissions.
