This one had wall to wall hype in the media. Odd thing was you only had to take the briefest of looks at the numbers to realize that even IF this device worked as advertised, it was almost completely useless.

100 millionths of a Newton of force for 100 Watts of power. Humans typically run at 100 Watts, and just me blowing on a balance can produce about 100 times that force.

Basically even IF this device worked as advertised, and was hooked up to a nuclear reactor, the extra power density of the nuclear fuel would mostly be cancelled out by the inefficiency of the engine, and you would be back at about the thrust to weight ratio of conventional rocket fuels.

Honestly though, this is going to be a rerun of that 'particles traveling faster than the speed of light thing'. It was a very difficult measurement that showed a speed slightly faster than light. Everyone knew sooner or later they would find the mistake in their experiment.  Same here. The difference between no thrust and the thrust measured here is almost nothing. 

Then you factor in the guy who came up with this idea is a crank who thinks this will give us hovercars.... and you just gotta be honest..... you have one very difficult to measure anomalous measurement. Whats more likely, a slight error in their measurement based on the ideas of a crank.... or we need to rewrite physics.....?

EM Drive BUSTED!

The hype of the EM drive has been truly remarkable. The creator claims they it will give us flying cars, cheap access to space, and solve global warming. The come the ground breaking news its passed peer review!!! Then you look at the details.

Did he think we could make a vessel that would not absorb the microwaves and convert them to heat so you could put more and more in and get more and more force??? I had a look at some of the more recent papers... if there numbers are true it may be worth switching over to EM at around 1/4 to 1/2 the speed of light or so compared with a pessimistic ion drive? But considering it should have a tiny thrust even compared with a photon drive because so many of the photons are leaking out the sides and top ... something for the researchers to clutch at anyway and they may find some new errors in measuring really small forces.

Can you imagine a world where engineers who promoted bullshit machines couldn't become engineers at all? Also, that entire peer review committee should be busted! Who is paying these people? The whole video looks like a sales pitch from Nigeria. He most certainly is not one hullava engineer. Send him back to India. And if he were Indian, you should do that anyway. Brain drain is great when it happens because you deny the adversary the information it needs to outsmart you. (Eg. The case where USA drains its own brain by returning foreign nationals to their own establishments.) Sometimes, it can be better to deal with less intelligence in exchange for more cohesiveness as a nation. Let France have their H1B1 visa recipient back. France deserves him. Now wait while this message produces loads of villainous pseudo-American adversaries. We should send them all to India. Lie: With their abortion rate, I heard India has plenty of room for our Syrians as well. They found space for the Dalai Lama. Perhaps we should be allowed to invest in cybernetic technology to balance our own intelligence in the global arena as a reward for not being reproductively selfish. And, that's good for the environment, too! There's no point in intellectual trade when you can't keep your secrets because half your workers remit them to their respective homelands. If we developed solar technology that worked, China would have a huge demand for that. We could encrypt the engineering methods and sell it to them, if the engineer leading the project weren't Indian or Chinese. He also shouldn't be Nigerian, for obvious reasons!

Thunderf00t is politically correct like I'm a social scientist. He's correct and not politically correct, and he's a scientist and not a social scientist. He's certainly not a social engineer! This is why the CIA *hates* Socialism.

would a sperm drive be more efficient than than the EM?

Can you imagine if someone were trying to kill you and you had to rely on technology like this? That's the horrifying truth for many of America's enemies. They are savages; They are inferior; They are losers. And we should not inherit their problems by sympathizing with them. If the Jews don't have enough space to move into their divinely ordained land, then perhaps we should make room for them. Instead, you get these Sarkeesian interdictors who defend our adversaries by delivering our super weapons to them to save them from the destiny that awaits every regressive answer.

Never allow idiots to have political power. Never under-estimate the power of idiots in quantity. They will all agree with each other on some wrong answer to get what they want in the short run.

If you steal all of someone's individual effort and the product of someone's merit, that's Communism. If you allow someone else to do the same, that's also Communism. Capitalism happens when money is an incentive that creates the optimal, broadest reaching wave of motivation for the good of the State and the world. Communism happens when a few have thousands of cars they don't need (and a yacht) and no one else can get one at all! So, then, they do nothing. If there's a big pile of food in the middle and all the nations surround it, then conserving that food becomes a team decision. That means that nations that do not comply must be ganged up on by the other nations so that no one nation can steal more than its fair share of food. Conservatism must be enforced! One nation in particular has stood out as a paragon or a bulwark in favor of this idea against the hordes of Socialists who despise conservative austerity. That nation is the United States of America, and it should take more nations to be able to overthrow our elder decision-making abilities. The proper purpose for money is incentivization. Money is not an instrument of avarice. That is what money is in Communist societies. We do not want a Communist society.

If you are afraid of a totalitarian society that cannot not face abolition, insurgency, insurrection, revolution, etc, then why the hell do you support globalism?!?! India is using austerity as a strategy to defeat us. We should be aware of that, adapt, and not allow our seeming inability to control ourselves to enable them to out-compete us. You cannot have success without suffering. There must be conflict. If it hurts to leave that hamburger on the shelf because you cannot yet afford it, that's pain leaving your body. By the same token, if you flaunt having something that other people can't get, no matter how hard they try, because you are just fitter and more pumped than they are, be afraid of the evil eye. You no longer have to be smart enough to be afraid of the evil eye because I just told you about it. Embrace shabby rich. Do not invest in unnecessary, gloating opulence unless your doing so is the outcome of an unequivocally fair competitive process. The world has been working this way for a long time. Progress has been made. And where the world hasn't worked this way, progress has not been made!
