The EM Drive is possibly the key to space travel without the high cost of fuel. Some say with the speed to get to the Moon in only a few hours and to Mars in a week. The technology uses microwaves as propulsion in a non reaction type engine that if it truly works will turn modern day physics on its head. It would be amazing to see true consumer interplanetary travel in the 21st Century. The video above is from Scott Manley a fantastic Youtuber who not only plays space themed video games but really knows his science. The second video is also from a fantastic science based Youtuber the video is a little shorter and he does a great job explaining what the EM Drive really is.
