OF RELATED LITERATURE Introduction Balloon powered car racers are driven by air coming from a deflating balloon. Instead of using electricity‚ these cars make use of the Law of Action and Reaction. The car is propelled forward‚ as a result of the air coming from an inflated balloon. As a reaction to the force produced by the escaping air‚ a force acts towards the opposite direction thereby pushing the car racer forward. Although balloon powered car racers have been around for quite a while

In regards to leaving Earth’s atmosphere‚ rocket engines haven’t undergone any drastic changes since their conception. Generally‚ rocket engines derive their thrust from a chemical reaction‚ involving a fuel and an oxidizer. This combination can be applied in liquid or solid form‚

Driverless cars should be on roads because they prevent car accidents‚ are self-evident and efficient. “Google has a fleet of driverless cars since 2009‚ and they’ve been driven over a half of a million miles without a crash” according to Jamie Page Deaton and Kristen Hall-Geisler in the article ‘Cars of tomorrow-still not fling.’ Humans get into an accident every a half a million miles‚ this shows that driverless cars are a safer alternative. These cars had a 3D model brain

Hybrid cars: Are Hybrid Cars Becoming Safer or More Harmful to the Environment? I. Introduction Hybrid cars have a very special technology because they boast two power sources: a regular gasoline engine and an electric motor powered by a huge battery unlike conventional cars which have only regular gasoline engine. These components generally work in tandem‚ though the exact mechanism varies depending on the car. When the car is at stop‚ the engine shuts off. While you push the accelerator
