Earth is getting crowded with every passing day. This forces man to look to the stars to live in. The situation gives rise to the idea of colonisation of space and the invention of EM drive, a space engine that moves forward without fuel makes it a reality.

EM drive is a comb-shaped chamber designed by Roger Shawyer, an electrical engineer. The device uses electricity to bounce microwaves in the inside. This movement creates a force at the end of the chamber that thrusts the engine forward. It still is in developmental phase, but it has passed the first stage of testing. During the process, EM drive speed was 272 degrees of rotation in 32 minutes. By then, the battery ran out.

Experts tried and failed to find if there was an unexplained fluke involved in the EM drive theory.

IBTimes UK obtained a copy of the EM drive paper but has refrained from publishing it as publishing it would go against journalism practices.

Pil Wilson, an EM drive fan from Australia, leaked the paper on the Internet. He feels that NASA will never publish the document. Besides, it is the taxpayers who funded the research. NASA is a US Government non-military organisation, and for this reason, what Eagleworks did does not belong to classified information. He also believes that information like this should come to the public view.
