In before somebody brings up dilithium crystals. I just did!

[grandpa jones]

yeah, this is the one the musloids used to go to the moon in 1635

In all reality. They need to stop talking theory and spend a million with a prototype, tracking suite, and a trip on a SpaceX Dragon.

Put one up and see how it flies. If its as successful as the theory purports, the proof of cost will be chump change.

The conservation of momentum isn’t violated just because the mass dispersed is too small to measure. If a miniscule even microscopic mass is dispersed at speeds approaching C, a great amount of momentum can still be maintained. The issue to me would seem controlled vectoring of such a device.

'The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.'

Anyone with a good physics background should be able to see that the thing produces thrust based on those 1/4-20 threaded rods.

[NonValueAdded]

Half the trip better be spent in braking.

EM Flux Capacitor Drive

[Rashputin]

Roger Shawyer got the idea from John Titor.

How long before some government bureaucrat declares that such an engine would damage the ozone layer upon activation, and make such engines illegal?

Oh Boy! Another perpetual motion machine.

Do some of you “old Freepers” remember about 10 years ago the guy who invented a perpetual motion device that was so amazing and secret that he could not demonstrate it in public? We had many hours of entertainment here at FR on that “amazing” invention.

I guess a new discussion on this wonder invention will be entertainment on FR for months to come.

It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber.

Well that’s good. I can’t imagine how you would generate just one microwave.

On a serious note it seems that the author is trying to make this out to be a GREEN rocket engine because it will be SOLAR powered.

But that would seriously limit the rocket’s utility to space travel near the sun. The further from the sun the spacecraft gets the less power would be available from the sun.

Bring her up to warp speed Scotty. :-)

[SgtHooper]

Solar powered. Hmmm, better travel in the light!! Keep it in the light!

[zeugma]

I want to see test results where they’ve actually been able to generate at least 10000 pounds of “thrust” with this engine. Then I’ll believe it.

[Pelham]

“has left scientists scratching their heads because it defies one of the fundamental concepts of physics –”

I suspect that there is very little head scratching going on, other than to marvel at the gullibility of journalists.

[ckilmer]

Why wouldn’t this technology be used to create vast amounts of energy at a fraction of prices currently paid?
