Electric CarsAn electric car is a plug-in battery powered automobile which is propelled by electric motor(s). Electric cars have the potential of significantly reducing city pollution by having zero tail pipe emissions. Vehicle greenhouse gas savings depend on how the electricity is generated. With the current U.S. energy mix, using an electric car would result in a 30% reduction in carbon dioxide emissions. Given the current energy mixes in other countries, it has been predicted that such emissions would decrease by 40% in the UK, 19% in China, and as little as 1% in Germany.
Full Cell VehiclesFuel cell vehicles (FCVs) have the potential to significantly reduce our dependence on foreign oil and lower harmful emissions that cause climate change. FCVs run on hydrogen gas rather than gasoline and emit no harmful tailpipe emissions. These vehicles are in the early stages of development, and several challenges must be overcome before these vehicles will be competitive with conventional vehicles. However, the potential benefits of this technology are substantial.
Gasoline-electric Hybrid CarsGasoline-electric hybrid cars contain the following parts.Gasoline engineFuel tankElectric motorGeneratorBatteriesTransmission
Solar CarsA solar car is an electric car powered by solar electricity. This is obtained from solar panels on the surface (generally, the top or window) of the car. Photovoltaic (PV) cells convert the sun's energy directly into electrical energy.
Compressed Air Cars
Electric cars have the potential of significantly reducing city pollution by having zero tail pipe emissions.The most obvious difference is the fuel cell stack that converts hydrogen gas stored onboard with oxygen from the air into electricity to drive the electric motor that propels the vehicle.
Advanced electronics allow it to act as a motor as well as a generator.When sunlight (photons) strikes PV cells, they excite electrons and allow them to flow, creating an electrical current.The car can be powered solely by air, or combined (as in a hybrid electric vehicle) with gasoline, diesel, ethanol, or an electric plant with regenerative braking.
