Space! EM Drive really does work

Submitted by: Goshin @ 02:41 PM | Monday, November 7, 2016 | (url: http://www.nextbi...)

MAN, it's fun being right

I posted about this in my giant space thread in the first few pages and you guys called me a crack pot! Well you can crack your own pot!

1.2 millinewtons per kilowatt in a vacuum
http://forum.nasaspaceflight.com/index.php?topic=40959.2480 has a ton of posts regarding stuff

propellant-less space flight
that means mars in 70 days whenever we want + more

fart in a bottle for me

so they got that figure by "measuring" 40 uN at 40 W and then scaling that up linearly, I FUCKING LOVE IT

STICK A TRUMP SIGN ON IT AND SEND ER UP TO SPACE

imma go ahead and trust them on this
especially since NASA has been discounting this technology for a decade while quietly trying to figure it out

now they have
and their brains is exploded

Goshin put his EM drive in a hot blonde once and documented it and shared with TribalWar.

Stuffed her with millions of killanewtons motha fucka

i totally believe these clowns have the equipment to measure micronewtons of force accurately

yea! fuck nasa scientists! think they're so smart...fuckin rocket scientist whatevers

But the EM Drive works without any fuel or propellants at all. It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity. That motion causes the 'pointy end' of the EM Drive to generate thrust, and propel the drive in the opposite direction.

Despite years of testing and debate, the drive remains controversial. The bottom line is that, on paper, it shouldn't work, according to the laws of physics. And yet, in test after test, the EM Drive just keeps on working.

Last year, NASA's Eagleworks Laboratory got involved to try to independently verify or debunk the EM Drive once and for all. And a new paper on its tests in late 2015 has just been leaked, showing that not only does the EM Drive work - it also generates some pretty impressive thrust.

To be clear, despite rumours that a NASA paper on these tests has passed the peer-review process, the version that's been leaked hasn't been published in an academic journal. So, for now, this is just one group of researchers reporting on their results, without any external verification.

But the paper concludes that, after error measurements have been accounted for, the EM Drive generates force of 1.2 millinewtons per kilowatt in a vacuum

That's not an insignificant amount - to put it into perspective, the super-powerful Hall thruster generates force of 60 millinewtons per kilowatt, an order of magnitude more than the EM Drive.

But the Hall thruster uses fuel and requires a spacecraft to carry heavy propellants, and that extra weight could offset the higher thrust, the NASA Eagleworks team conclude in the paper.

Light sails on the other hand, which are currently the most popular form of zero-propellant propulsion, use beams of sunlight to propel them forward rather than fuel. And they only generate force up to 6.67 micronewtons per kilowatt - two orders of magnitude less than NASA's EM Drive, says the paper.

The NASA Eagleworks team measured the EM Drive's force using a low thrust pendulum at the Johnson Space Centre, and the tests were performed at 40, 60, and 80 watts.

They were looking for any sign that the thrust could be a result of another anomaly in the system, but for now, that doesn't appear to be the case.

"The test campaign included a null thrust test effort to identify any mundane sources of impulsive thrust, however none were identified," the team, led by Harold White, concluded in the paper.

"Thrust data from forward, reverse, and null suggests that the system is consistently performing with a thrust to power ratio of 1.2 0.1 millinewtons per kilowatt."

But the team does acknowledge that more research is needed to eliminate the possibility that thermal expansion could be somehow skewing the results.

They also make it clear that this testing wasn't designed to optimise the thrust of the EM Drive, but simply to test whether it worked, so further tweaking could make the propulsion system more efficient and powerful.

So where does this leave us with the EM Drive? Again, the results haven't been published as yet - although rumours are circulating that we're getting tantalisingly close to that happening - so we need to take these leaked results with a grain of salt.

But they do offer further evidence that the thrust produced by the EM Drive is real. So it might be time to start trying to figure out how the system could work - and, more importantly, start testing the drive in space.

Thankfully that's scheduled to happen in the coming months, with the first EM Drive already having been launched into space back in September.

And back in June, a team of researchers from Finland proposed a way that the EM Drive could work without defying Newton's third law, by propelling photons as a type of exhaust - although that hypothesis has yet to be tested.

We're still a long way off understanding how the system works - or if it works at all - but a lot of brilliant minds are now seriously considering the possibility that we might have a way to get to space without rocket fuel. We're excited to see what happens next.

anyone that describes it as "pointy end" is allllllright in my book

Fucking clickbait bloggers, how do they work?

No seriously, let's cut THEM ALL open and find out.

hey fuckhead, I don't feel like spending 5 minutes finding a suitable website with the info
hence why the clickbait quote is 8 posts down

the technical shit is up top. but you faggots don't read so the click BS website does a decent job giving you the take away

they test this shit in space yet like they said they were going to?

anyways, we know light has momentum and you can already build a nuclear powered rocket that emits light as propellant. this drive is controversial because it supposedly generates more thrust per watt than you would get if you just fired microwaves out the back end. it also violates conservation of momentum if it is actually reabsorbing every photon that it emits.

u kno wat doesn't work?

goshin

lmao amirite

I'm still not over how you called this "warp drive" in an earlier redundant redundant post.
