NASA has shown how a fuel-free engine may lie in the cards. While for now it is pure sci-fi, in the future its an idea worth exploring.

A fuel-free engine is like a perpetual motion machine. This may look good in theory yet practically it has no value since it is impossible to make.

Yet NASA has set aside time and money for some research regarding an EM Drive. Testing mankind’s wish for a form of spaceship propulsion that does not require any input is something which is far out and wild. 

To make thrust possible in a vacuum without any propellant fuel is a dream of mankind. Reality is a more rigid form of obstacle though and does not allow for any such thing.

Termed an EM Drive, it is supposed to use microwaves that collide in a cone-shaped hermetically sealed contraption. The momentum of these microwaves builds up at the wider end of the cone.

Thus this is supposed to produce thrust. The thrust that is produced is higher than the sort of propulsion created by photons. The research paper presented by NASA has passed peer review. 

The lively discussion regarding the EM Drive is back with a vengeance. The scientists are formulating all kinds of wild theories. Yet as they say, an ounce of practical is worth a ton of theory.

What works in reality is what counts in the end. Were such a form of power caught in service of space travel, the very field would undergo a revolution.

We could in fact travel to Mars within 41 days using such a special futuristic technology. It has been labeled as the impossible drive for no reason other than the fact that it manages to flout a few of the iron laws of physics.

This may appear to be a travesty but that is the way science works. With every paradigm change, humanity moves forward accepting the new and discarding the old. 

Both the law of conservation of momentum and Newton’s third law would be virtually broken were this EM Drive to become a reality. That day may not be far off.

The problem the scientists have encountered is that they have no means of explaining away the thrust seen in case of an EM Drive. It is still a mystery.

A peer-reviewed paper, published online in the American Institute of Aeronautics and Astronautics' Journal of Propulsion and Power, may offer a peek at tomorrow yet a lot needs to be done before this dream is converted into reality.
