  Hybrid Electric Vehicles   (Site not responding. Last check: 2007-10-14)
This vehicle is an electrically charged battery pack, coupled with a small internal combustion engine, capable of producing minimal emissions with a longer range than that of a battery run vehicle alone.
Ultimately, the hybrid electric vehicle design is to be a cost-effective, highly efficient, ultra-low exhaust emission vehicle capable of equaling or exceeding present vehicle performance, safety and customer appeal standards.
The electricity used to power electric vehicles is readily available and can be produced from a wide variety of sources including coal, natural gas, nuclear, solar and various other power sources.

 Hybrid Electric Cars and vehicles, Her Electric Vehicle   (Site not responding. Last check: 2007-10-14)
Hybrid electric vehicles are, again, simply those vehicles with an on-board source for generating electrical power.
The disadvantage to such a hybrid vehicle is that its piston engine has all the drawbacks of the engines in conventional vehicles: Noise, pollution (unless powered by compressed or liquid natural gas [C/LNG] or propane [LPG]) high moving parts count and poor reliability with age.
Instead of spinning a mechanical generator to produce electrical power, the fuel cell produces electricity by capturing the electrical discharges produced when certain chemicals are combined (or, as is often the case, re-combined).

 Hybrid Electric Bus
BC Transit purchased six hybrid buses to evaluate environmental and economic benefits of operating hybrid electric buses in the Kelowna and the Victoria regions.
This captured electrical energy is then used to assist in powering the bus using quiet electric motors and adding to the vehicle's efficient use of the diesel engine.
Hybrid electric buses utilize two power sources: a smaller than normal internal combustion engine and an energy storage unit (the battery).

 Hybrid Electric Vehicles
Hybrid electric vehicles (HEVs) combine the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle.
The electric motor is used primarily for low speed cruising or to provide extra power for acceleration or hill climbing.
When braking or coasting to a stop, the hybrid uses its electric motor (3) as a generator to produce electricity, which is then stored in its battery pack (6).

 Hybrid-Electric Drive   (Site not responding. Last check: 2007-10-14)
Unlike the mechanical torque generated by a conventional system, the hybrid's electricity can be stored temporarily in a small battery or other similar device until it's needed for extra acceleration.
Additionally, the electric motors of a hybrid vehicle can recover part of the braking energy that would otherwise be lost as heat in the brakes.
Hybrids generate their own electricity onboard, so they don't have to haul around hundreds of extra pounds of storage batteries, nor do they suffer from the short driving ranges and long recharging times of battery cars.

 Hybrid vehicle - Wikipedia, the free encyclopedia
Hybrids other than electric-internal combustion exist, for example hydraulic and pneumatic hybrids, where compressed fluids and compressed air, respectively, are used for energy storage with regenerative braking.
Like many electric cars, but in contrast to conventional vehicles, braking in a hybrid is controlled in part by the electric motor which can recapture part of the kinetic energy of the car to partially recharge the batteries.
Hybrid drivers also benefit from a discount in their insurance if they are insured with "MORE TH>N" who recently announced a discount for hybrids drivers in the UK of up to 13 per cent.

 How Hybrids Work   (Site not responding. Last check: 2007-10-14)
Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.
The electric motor applies resistance to the drivetrain causing the wheels to slow down.
In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.
