Electric Vehicles (Save The Earth)

Due to the pollution made by vehicles various kinds of effects are been made to the nature. It is directly effecting the the nature as well as the living being's health. Pollution is like a slow poison which creates various natural calamities as well as various kinds of diseases. So as to minimize the problems we can use electric vehicles and solar vehicles. The companies concerned with making various petrol and diesel vehicles should make a effort to launch the electrical vehicles which would be beneficial to the peoples health as well as it would save the eco-system. Electrical vehicles also helps to reduce the Noise pollution. The vehicles are itself very silent than other vehicles which are operated from petrol and diesel.

Multistage Rockets

Multistage rockets are launched by the recoil pressure of the burning gases. As the fuel burns it emits. There are more than one stages before they get empty. One or more then one rockets are attached parallel next to each other. It reduces the total amount of the massive structure which is needed to be accelerated to its final speed. In each stage it consists of more than one motors, fuels and oxidizer tanks, which is termed as staging in rocket science. It gives high speed and great accuracy in the distance. Rocket boosters which are in Solid or Liquid form are also used for parallel staging. And all the motors are switched on for more efficiency.

Cruise Missile

Cruise Missile is a object which is based on lifting wing basis. It is generally designed to carry a huge amount of nuclear to be used in the wars, it can carries huge amount of nuclear displacing hundreds of miles distance with the excellent accuracy. Daily more and more advanced missiles are being made. It travels a long distance without any man in it, so it can also be considered as unmanned aircraft. It gradually travels at a high speed, it can be navigated by itself. In order to avoid radar detection it flies in low height. It is perfect weapon for wars but is a lot destructive.
