  • Essay / What should we drive when oil runs out? - 613

    In this report, I will discuss the advantages and disadvantages of various alternative fuels for cars and vehicles. Here are some of the fuels I will be looking at: -Bio diesel-Ethanol-Nuclear-Hydrogen-Compressed airBio diesel:Advantages: -It is safer to handle.-Bio diesel is a renewable fuel that can be made from vegetable oils. , animal fat.-It does not pollute the environment as much as gasoline does these days and creates 15% less greenhouse gases than gasoline.-Disadvantages:-Bio-diesel gels in cold weather , but the exact temperature depends on the material from which it was made. . (This won't be of any use to cold countries like Russia or Canada. - It gets moldy. I suppose if you collect it and remove it before it reaches that stage it should work but in some case, it could cause problems -It is expensive.Nuclear:Advantages: -It is not expensive.-It is the most concentrated source.-It is very efficient because it can create a lot of energy. and generate some pollution.Disadvantages: -It can be dangerous like nuclear power Electric power can be very disastrous because it can create health risks due to radiation -Nuclear waste will have to be stored somewhere, nowadays they. are packed up and put underground but in the long term this will not be the best solution because we are short on space, and nuclear power is currently indestructible (Getting rid of waste can be problematic.) - As I said. As already mentioned, radiation can cause health risks to people, including deformity, illness or death. ...... middle of paper ...... is estimated at $17,800, or approximately £10,852. 11p, which to be honest is cheaper than most cars. Disadvantages: - The air cools considerably when enlarged. in the engine, so it would be uncomfortable during the winter season.-Energy is lost when electrical energy is converted into compressed air.-The weight and price of many safety devices such as airbags may cause manufacturers to do not include them. in cars. This one is a bit off-topic because it writes more about the car itself than the fuel, but personally I found it very fascinating how a car can run on compressed air.
