What is a hydrogen car???

  1. Internal combustion engines, e.g. the Otto-cycle engine used in most cars, can burn a variety of fuels. Gasoline works, but so does propane or hydrogen. It's comparatively easy to change fuels on an existing engine, or, better, design an engine to run best on a specific fuel such as hydrogen (H2).

    Why H2? It burns cleanly, with no carbon dioxide emission and other pollutants, such as nitrogen oxides, are easily controlled. Why not H2? Because hydrogen must be produced; it is not naturally occurring in large quantities, unlike propane. The process of making H2 from water uses energy, often from a fossil fuel such as coal.

    Another problem with H2 is storage. Since not much mass fits in a tank, a car won't go far.


  2. A car that has hydrogen as its fuel. The car would be equipped with a hydrogen generator which would convert water (old H2O) to hydrogen gas which is used for fuel. It is not expensive as some have said. Chemistry labs have been using these generators for 15 years or more and they are safe. All one needs is water and 22% Sodium hydroxide and both are cheap. The cars are expensive because they are not mass produced as yet.

  4. a car that runs on a hydrogen instead of gas.

  5. It is a car that runs on hydrogen gas instead of gasoline or diesel.

    Hydrogen cars designed so far either use one of two types:  a combustible piston type engine or a fuel cell.

    Fuel cells have been used by NASA since about the 1960's.  They are more efficient than an engine that combusts hydrogen with the standard piston type engine.  Fuel cells use more of a chemical process than a mechanical one to combine the hydrogen with oxygen, creating water, electricity and heat in the process.  The electricity and heat collected can be used to power the car.

  6. Hydrogen is the most common element in the universe.  It can be compressed in metal tanks - which look just like oxygen tanks - and used to run car engines.

    Hydrogen can also be produced from water (water = 2 molocules of hydrogen bonded to 1 molocule of oxygen.  H2O)   Some scientists are working on an engine that will use water as fuel, produce the hydrogen needed to fuel the engine, and release only oxygen back into the environment.

    The main problem with hydrogen cars right now is that virtually no gas stations sell hydrogen tanks so you can't fill up anywhere.

  7. a car similar to any other car, except instead of burning gasoline, it uses a special "fuel cell"

    this cell works by collecting hydrogen on one side of a special net, and regular air (and therefore oxygen) on the other. Because pure hydrogen is unstable and air is not, the hydrigen wants to fill its electro shells by bonding with oxygen to make water. when the hydrogen passes through the special net, the net removes the electrons, and terfore the energy, and then puts them into an electric motor.

  8. A hydrogen car is a sad excuse for alternative energy, especially considering that there were electric cars in the USA not too long ago. The hydrogen car costs about $100,000 and the fuel is so expensive.

  9. a non-existent potential auto to run on H20.  You full your tank with water - aluminum and some other ingredient are use in a catalyst to transform the water into Hydrogen gas fuel and give off oxygen as an exhaust
