Nowadays, carrying loads into orbit is a very complicated process, and therefore very costly. Engineers from Escape Dynamics, however, are working on a completely new microwave-powered spacecraft propulsion system that should significantly reduce the cost of this venture.
Microwave radiation is used in a variety of devices, in military radars, as well as home cookers, allowing us to quickly prepare meals. Soon, however, it may find a whole new use, as Escape Dynamics plans to use it to revolutionize space travel.
Engineers have recently tested the new reusable space vehicle engine, which instead of expensive fuel, allows you to rise to the stratosphere using microwave energy.
In traditional rocket launch systems, liquid fuel engines are used, which is a very inefficient type of propulsion and at the same time extremely expensive in operation. Escape Dynamics, however, has a completely different idea, and instead of boosters, it wants to use a series of ground-emitting microwave emitters that will send energy to the heat shield of the rocket. This energy will be used to propel an electromagnetic engine that will use a small amount of fuel (hydrogen or helium) to propel it and it will bring the vehicle into orbit.
Engineers will ensure that a new helium-driven engine will be able to deliver the string for about 500 seconds. For example, the standard chemical fuel rockets reach it for a maximum of 460 seconds. When hydrogen is used, it will increase to 600 seconds.
