Nasa is a major player in space science, so when a team from the agency this week presents evidence that "impossible" microwave thrusters seem to work, something strange is definitely going on. Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion.

British scientist Roger Shawyer has been trying to interest people in his EmDrive for some years through his company SPR Ltd. Shawyer claims the EmDrive converts electric power into thrust, without the need for any propellant by bouncing microwaves around in a closed container. He has built a number of demonstration systems, but critics reject his relativity-based theory and insist that, according to the law of conservation of momentum, it cannot work.

According to good scientific practice, an independent third party needed to replicate Shawyer's results. As Wired.co.uk reported, this happened last year when a Chinese team built its own EmDrive and confirmed that it produced 720 mN (about 72 grams) of thrust, enough for a practical satellite thruster. Such a thruster could be powered by solar electricity, eliminating the need for the supply of propellant that occupies up to half the launch mass of many satellites. The Chinese work attracted little attention; it seems that nobody in the West believed in it.

However, a US scientist, Guido Fetta, has built his own propellant-less microwave thruster, and managed to persuade Nasa to test it out. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio. Astonishingly enough, they are positive.

A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive deep-space missions, and take astronauts to Mars in weeks rather than months. In hindsight, it may turn out to be another great British invention that someone else turned into a success.

AWESOME.

Now, let's fund NERVA again.

2   The Original Bankster   2014 Aug 5, 3:53am  

why dont we fund space programs any more?

geez its the only thing I can actually get excited about.

3   The Original Bankster   2014 Aug 5, 3:55am  

just watch this to give you an idea of how small our little planet really is

also, Gary- does Jesus also rule other planets?

Supporting microwave research will be key in harnessing solar energy via satellites and deep space probes. But of course, with all that coal underground, who cares.

Because they are hugelly expensive and have diminishing returns. There is also nowhere to go that isn't instantly lethal.

Now if astronomers were to discover a planet populated exclusively by insanely amorous, unimaginably attractive, STD free young third world women I have no doubt there are many on this forum would sell their RE empires in a heartbeat to fund an interplaetary expeditionary force.

The good thing is that coal-to-gas synfuel production will keep chemical engineers employed.

If this holds up to peer review it will be a big break through in not only space craft propulsion but also QM theory.

9   Tenpoundbass   2014 Aug 5, 5:33am  

Are you guys still bitching about Coal?

You won already, don't you even follow the news?

http://www.nytimes.com/2014/05/29/us/politics/obama-to-offer-rules-to-sharply-curb-power-plants-carbon-emissions.html?_r=0

Florida has projected that our already $300 electric bill will raise to $500 in the next three years. FPL is just going to do away with coal plants because it would cost to much to meet the fantasy target. Clean coal has reached the ceiling. Plus they know if they did find another way. The next populous moron will demand even higher electric bills.

They are also a major player at my airport - as long as they are getting funding they will stay and expand at my airport. Works for me.

This was an episode of The Big Bang Theory. The Chinese team said they validated the results simply to get credit for doing work, but really they did nothing, assuming that Sheldon had gotten the theory correct.

Even if this turns out to be a lot of hot air (sorry, plasma), the work in microwave transmission and containment will be useful for when future solar collecting satellites, start to delivery 24 hour energy to the surface.

Give it a century or so for development.

In the meantime, the US is already finishing up a coal-to-gasoline facility in West VA and it's scheduled for 2016.

Thus, there's no impending energy shortage, only profiteers who prosper from inside information.

14   Shaman   2014 Aug 5, 7:50am  

Do you really think we haven't cracked cold fusion yet? Talk about your disruptive technologies... No effing WAY the energy lobby would let that come out! Free energy would drive an entirely different sort of economy that land barons, rentiers, and warlords would have no part in.

Ask about the soap less washing machine. Invented decades ago and promptly acquired by the detergent conglomerates.

Yes, I agree, as I get dividends from not only tobacco but also, utility stocks.

No free energy until I'm in the grave. Between now and then, it's King Coal baby!

Well, peak oil's a myth, as there's already 200+ years of coal underground, regardless of the projected fracking and sand tar supplies. That's a fact and coal to gasoline is a proven long term technology solution, as indicated by Sasol Corp in South Africa.

Thus, current gas prices support coal to gasoline build outs and those projects are already in the pipeline.

Green means 22nd century, not today.

In that distant future, solar satellites, using special materials, will convert a bulk of solar radiation into microwaves, and beam it back to collecting stations to earth, to feed the grid.

18   Tenpoundbass   2014 Aug 5, 9:11am  

I totally agree with about the supply and availability of Oil.

But Green energy could be a reality today if America was more industrious and we had more entrepreneurial spirit over novice investor society that we are.
As long as starting a Green energy endeavor is more about investment, dividends and projected profits based on Federal programs and mandates.
Then Green energy will never see the light of day. Not in the 22nd or 23rd century. That's not to say that those who can't afford it, wont have to do with out. Sooner than later a technology that has 80% administrative and profit costs baked in will be mandated on the public whether they can afford it or not. and Like Mandated healthcare using the same 80% model has been imposed on the most destitute public since the start of Postwar America.

There's a cultural change here. The 20th century is over and thus, the rest of the world will not be looking at the US, as the R&D workshop of the globe.

Science R&D, corporate or institutional, will be a global thing. I wouldn't be surprised if the Singapore-to-Seoul Pan Pacific consortium, circa 2030, launches the first solar satellite with microwave transmitters. And from there, they can make either gradual or dramatic R&D in those areas, without support from the US's Dept of Energy or any of our alphabet soup depts.

Our universities are already starting pilot programs abroad, to spread their brand name with Asia-Pacific denizens. I believe the Univ of Chicago has a campus in Singapore already.

So I wouldn't worry too much. We can get fat and lazy on our coal deposits, while the rest of the world makes advances in real science and engineering.

20   Tenpoundbass   2014 Aug 5, 9:41am  

I happen to know that you are correct on all counts.

The whole South Asia region get's technology two years before we hear about a future release date.

South Asia is India and that's not where it's at. Albeit, it's the current popular offshoring destination for corporate America but for the most part, it'll languish as a body shop for decades.

It's the zone from Singapore to Seoul, the east Asian Pacific Rim, which is the future, as they're nimble, more interested in technology, and don't have a century to wait, by sitting on a pile of coal.

22   Tenpoundbass   2014 Aug 5, 9:55am  

I never understood why East Asia is South of India.

I was in Malaysia in 2008, they had things I didn't see in the States until last year.
Like our short lived Clear internet company. That quickly came and went.
They had G4 access points with reasonable prices for people on their wages.
I remember seeing an advertisement for the Galaxy S in 2008 in the Singapore Air port and wondering if Apple would ever allow them in the states.

23   Rin   2014 Aug 5, 10:15am  

I'd been to a number of countries in Asia-Pacific: Indonesia, Singapore, Malaysia, Thailand, PRC, Korea, and Japan. The difference between there and here is that they're not sitting around and waiting for the the future to arrive.

Granted, China's a small 'King Coal' country but the rest of them aren't these mega energy mills like the Middle East, Russia, or North American Union.

For east Asia, it's about making the future happen w/o the luxury of simply logging one's hours, at some energy company. As a result of this hastened attitude, if solar-microwave becomes real, it'll happen on their watch and not ours.

24   Tenpoundbass   2014 Aug 5, 10:19am  

Well if you've been there, no wonder you're not getting married.
I really had to struggle with my self to come back.

Yeah, thank goodness that women in Korea, PRC, & Japan were shy, otherwise, I would have been dodging 'em all over the place.

I was in SE Asia in 2004, and tech, both devices and services, were everywhere at far more reasonable prices than the States.

Funny how Windows XP cost like $20 in Thailand but $100+ in the US. Who knew CDs were so heavy. "No customer support outside Asia." the box said.

That happens to everyone in the touristy areas of Thailand. The grand majority of the people are quite conservative however. They don't even like wearing bikinis to the beach, let alone going topless like the acres of European revelers.

30   Shaman   2014 Aug 5, 11:53am  

I'm fairly convinced that technology is being actively suppressed in the USA. Anything that is disruptive, that is a new technology that would harm current industry is being quietly killed or acquired and buried. There are a lot of American inventors in shallow graves. When the choice is between a ten billion dollar industry and a couple of guys with post docs from MIT, the math becomes crystal.
Read "Influx" by Daniel Suarez for a look at what might be.

Here's the thing about the EmDrive that fascinates me (assuming it holds up..unlike Cold Fusion, or the faster than light experiments).

In the Pantheon world of The Science, shouldn't Elon Musk and Stephen Hawking have discovered this. And wouldn't Jeff Bezos and Richard Branson be building these right now at their private space companies.

Instead, what seems to have happened is what I would expect in the real world. A truly new idea appears and it's roundly dismissed as impossible. Then, a group that has no stake in the Old Order, looks at it and says...mmm...interesting and makes it work (China). Then the Establishment awakens and says....oh, yeah, we can do that too! They being dowdy old NASA...not Entrepreneurial Billionaires.

This process, by the way, has nothing to do with Neil deGrasse Tyson.

33   HydroCabron   2014 Aug 5, 12:12pm  

It isn't a viable technology until Elon Musk is losing money on it.

For one, I work in finance and have met CEOs, portfolio managers, private equity partners, etc, and let me tell you this ... many of those folks are a bunch of well-connected bozos. In other words, attending Wharton, London Business School, Harvard Business, etc doesn't make one a visionary or a next generation Nikola Tesla.

At the same time, I realize that if one isn't truly financially independent, one doesn't want to work for an organization which will either steal your ideas or fire one for having 'em, then one can't really innovate.

Thus, I don't believe that Musk, Branson, or Bezos are creative geniuses. These are rich folks who like the media attention of being eccentric or eclectic but have their noses on what enhances their public image.

When they say that this technology is "potentially demonstrating an interaction with the quantum vacuum virtual plasma," is that their way of saying that they have no fucking idea why it works ?

Btw zzyzzx, congratulations on posting something other polls about how much everyone hates Obama. This is very interesting.

Pretty much. A couple of well-informed sources have laughed heartily at this characterization of the quantum vacuum.

Also: they even measured thrust when the device was turned off, which does call into question their setup.

I hope this is true. I am nearly certain it's not, but we'll have to wait.

37   marcus   2014 Aug 5, 1:10pm  

Nasa is looking at warp drives too. Although, that's even less likely, unless all this stuff is being reverse engineered from crashed alien ships (as long as we're talking unlikely).
