Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It’s called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can’t explain why.
Shawyer’s engine is extremely light and simple. It provides a thrust by “bouncing microwaves around in a closed container.” The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusts can work forever unless a hardware failure occurs. If real, this would be a major breakthrough in space propulsion technology.
Obviously, the entire thing sounded preposterous to everyone. In theory, this thing shouldn’t work at all. So people laughed and laughed and ignored him. Everyone except a team of Chinese scientists. They built one in 2009 and it worked: They claimed they were able to produce 720 millinewton, which is reportedly enough to build a satellite thruster. And still, nobody else believed it.
Now, American scientist Guido Fetta and a team at NASA Eagleworks—the advanced propulsion skunkworks led by Dr Harold “Sonny” White at the Johnson Space Center—have published a new paper that demonstrates that a similar engine working on the same principles does indeed produce thrust. Their model, however, produces much less thrust—just 30 to 50 micro newtons. But it works, which is amazing on its own. They haven’t explained why their engine works, but it does work:
this is NOT hd
HD???….. i have been deceived…. its LD..Low Definition.
What we imagine will happen eventually. Our imaginations are a glimpse into the future.
how on earth or anywhere else in the universe is this deffined as HD?………..
not HD or anywhere near it. I don't like deception.
To put space travel in perspective the distance light travels in one year is called a light year. To cross from one end of the milkyway galaxy to the other at the speed of light it would take you around 100,000 years. That is about 1,428 human generations at an optimal human life span. The next nearest galaxy is 2.2 million light years away. 100,000 light years / 70 avg human life span.
I can not begin to stress enough how big of a money pit space travel is until humans find a way to travel many times faster than the speed of light. If you want to invest time, energy and money on something I would start with our own earth for the foreseeable future.
Brings to mind when Winston Churchill's top science advisor during WW2, said the jet engine "couldn't knock the skin of a rice pudding"
