Butanol Fuel

A Brief Description:

Butanol or butyl alcohol is an alcohol with a 4 carbon structure. Butanol is primarily used as a solvent, as an intermediate in chemical synthesis. Butanol may be used as a fuel in an internal combustion engine. It is in several ways more similar to gasoline than ethanol is. Butanol has been demonstrated to work in some vehicles designed for use with gasoline without any modification. It can be produced from biomass as well as fossil fuels. Some call this biofuel biobutanol to reflect its origin, although it has the same chemical properties as butanol produced from petroleum.

Hybrid-Electric Vehicle

A Brief Description:

HEV is a vehicle using gasoline (petrol) or diesel to power internal-combustion engines and electric batteries to power electric motors. They are low-polluting and low-petroleum consuming cars.

Nuclear Power

A Brief Description:

The controlled use of nuclear reactions to release energy for work including propulsion, heat, and the generation of electricity. Human use of nuclear power to do significant useful work is currently limited to nuclear fission and radioactive decay. Nuclear energy is produced when a fissile material, such as uranium-235 , is concentrated such that the natural rate of radioactive decay is accelerated in a controlled chain reaction and creates heat - which is used to boil water, produce steam, and drive a steam turbine. The turbine can be used for mechanical work and also to generate electricity. Nuclear power is used to power most military submarines and aircraft carriers and provides 7% of the world's energy and 17% of the world's electricity. The United States produces the most nuclear energy, with nuclear power providing 20% of the electricity it consumes, while France produces the highest percent of its energy from nuclear reactors - 80% as of 2006.
