NASA tests ‘impossible’ microwave engine that produces fuel out of empty space — and finds that it works
AUGUST 04, 2014 11:52AM

‘I CANNAE break the laws of physics” Star Treks’ famous engineer “Scotty” would retort.

But NASA has. They’ve produced something from nothing, and perhaps opened a way to the stars in the process.

Scotty has to eat his hat: And the new microwave propulsion system has been named the “Cannae Drive”.

An initially sceptical NASA decided to test a widely criticised concept from inventor Roger Sawyer — even though established thinking said it wouldn’t work.
It did.

The engine appears to produce propulsion through electricity. And nothing else.

The usual expectation is that thrusters need to eject some kind of mass in order for the old law of physics “equal and opposite reactions” to kick in. For example rocket propellant is burnt and ejected from a thruster in order to propel a rocket upwards.

It’s the major problem all rocket scientists face: How to get the maximum thrust from a minimum weight of fuel.

This does not appear to be the case when it comes to quantum vacuum plasma thrusters — or microwave drives.

If proven, the engine would have significant implications for the space program.
Solar panels would provide satellites with all the energy they need to constantly adjust their orbits — boosting the life of such expensive devices significantly.

NASA’s Harold White — who is leading research into “warp drives” — has previously said engines such as this microwave drive have the potential to propel humanity to the closest star to the sun, Proxima Centauri. It could reach the red dwarf star, some 4.2 light years away, within 30 years.

They’re not sure how it works.

But NASA has gathered a pool of data suggesting it does.

It’s not a huge result: In fact, the thrust appears to be tiny — leading to some suggestion the experiment itself is flawed.

But the original microwave drive inventor has taken the opposite stance, saying NASA’s experiment produced far lower thrust outputs than his own.

Perhaps they should listen: Roger Sawyer has been met by largely deaf ears for the past decade as he attempted to extol the merits of his new drive.

While criticism of his concept was abundant, nobody has managed to prove it wrong.

Behind it all is some pretty speculative quantum physics.

At the tiniest of all known scales, the universe does not seem to obey its own rules.

One of the concepts this drive claims to exploit is an effect called quantum vacuum fluctuation: Where particles spontaneously create themselves in the vacuum of space, before quickly blinking out of existence again.

Somehow, these rare — here one minute, gone the next — particles are being captured and turned into plasma inside the microwave drive. This plasma, when directed, imparts thrust.

If true, it’s a source of fuel delivered direct to the engine — without weighty or dangerous fuel tanks.

And it’s constantly re-creating itself.

Too good to be true?

bingo!

something from nothing

therefore....sound may exist too

Heh... perhaps the laws of physics are really more like guidelines Very Happy

It is extremely fascinating and I'm looking forward to further study as the kinks are worked out . It will take time and money but the spark is there... now to perfect the flame .

Certainly looks promising. Even a tiny bit of steady thrust, will accelerate an object through space.

Yep Mordman. The Photon drive will do that if it ever gets started.

The claim that this donk produces power from nothing is not quite true though. It needs a supply of electricity be that external or internal, to work. So it's not producing "Something from nothing"!

It would not necessarily work in deep space if it had to rely on sunlight to power it. Not many suns nearby to give it juice!

True, but if you can get the acceleration while your still "in-system" it may not be to big an issue. Add to that the option of "sling-shotting" around planets further out and it still may be viable.

I wonder if this type of power engine could also be adapted for a home attached power generator?

Yep. There are always ways around such a problem. According the Physics Laws, a body accelerating will keep on doing so until something else changes it (i.e. like something dark and rocky!).

That power system would be good for zipping around our solar system but.

Interesting concept Len. EIEO is the equation. Work around that and you'll be rich beyond your wildest dreams!

I just wish to be comfy for my remaining years, and to liberate people from the tyranny of the fossil fuel power companies, and stick it in their eye
