Banned Engines That Will Never go Into Production and Here's Why!

Mankind has dreamt of travelling to other galaxies for many years. But what will the ships that carry us to the stars by powered by? Definitely not jet fuel – it’s too expensive, and there are limitations to speed. One possible alternative is a microwave engine! Yes, you heard that correctly: the very microwaves that heat up your leftover pizza! For example, the EmDrive engine, which was developed by Briton Roger Shawyer could be used. NASA even recognized the technology as perfectly viable. No chemical fuel nor any waste! Impressive, right? However, there are still some large unknowns regarding the EmDrive. Researchers have not yet been able to prove whether this engine can actually power space flight or not. As they say, the truth lies somewhere in between!
