| One of the big news is that crude oil hit $135 per | | | | Hydrogen Powered Cars : It is run by the help |
| barrel and it is really going to affect every people | | | | Hydrogen as a fuel. The power plants of such |
| directly or indirectly. New report says that it will reach | | | | vehicles convert the chemical energy of hydrogen to |
| $200 barrel very soon. Then there will be chances | | | | mechanical energy (torque) in one of two methods: |
| that we would not be able to afford it and after | | | | combustion, or electrochemical conversion in a |
| some time petrol will extinct from the earth. We | | | | fuel-cell. In fuel-cell conversion, the hydrogen is |
| should ready for that condition and start looking for | | | | reacted with oxygen to produce water and |
| alternative option of petrol cars. I have found some | | | | electricity, the latter of which is used to power an |
| alternative and made list of it | | | | electric traction motor. A potential advantage of |
| Solar powered cars: They are best alternative of | | | | hydrogen is that it could be produced and consumed |
| petrol cars because it runs by the help of sun energy | | | | continuously, using solar, water, wind and nuclear |
| and there is no end of sun energy it will remain as | | | | power for electrolysis. Currently, however, hydrogen |
| long as earth. But major drawback of it is that we | | | | vehicles utilizing hydrogen produce more pollution than |
| wont be able to drive it at night time and in that you | | | | vehicles consuming gasoline, diesel, or methane in a |
| would not be able to go on night drive with your girl | | | | modern internal combustion engine, and far more |
| friend. | | | | than plug-in hybrid electric vehicles. This is because, |
| Compressed air Cars : The air car is powered by an | | | | although hydrogen fuel cells generate no CO2, |
| electric pump that compresses the air into a tank, | | | | production of the hydrogen creates additional |
| the air in turn pumps some pistons. The cars top | | | | emissions. |
| speed is 70 mph (115 kph) and it can travel up to 50 | | | | Battery electric Cars: The battery electric Cars utilizes |
| miles (80 k) on a full 'tank'.(supposedly further at | | | | chemical energy stored in rechargeable battery |
| lower speeds). The pump that is used to power the | | | | packs, and electric motors and motor controllers |
| car simply plugs into a normal household socket and | | | | instead of internal combustion engines (ICEs). The |
| takes four hours for a full charge. As fro the cost of | | | | main advantages of battery Cars are that no |
| a full charge, apparently only $2.50 at French | | | | pollutants are emitted directly by the vehicle |
| electricity prices. The only emission to come out of | | | | potentially reducing urban pollution and petrol is |
| the exhaust is cold air. The only emission to come | | | | replaced by electricity. The electricity stored within |
| out of the exhaust is cold air. It'll cost next to nothing | | | | the battery can be generated by any source, |
| to run (how do 30,000km service intervals sound?), | | | | including renewable, nuclear, natural gas, coal and |
| have a range of up to 1000 miles, and retail for well | | | | petroleum. Battery cars are getting popular these |
| under US$20,000. it will launch up to 2010 in America | | | | days. There is also reduction in noise pollution. |
