Moderator, please kill this stupid, stupid thread. It hasn't got a single thing to do with electric motorcycles! If necessary, please terminate participants as necessary to keep this thread dead.Truth hurts [emoji23]
The arc reactor lives! And here I thought Tony Stark was a fictional character. Silly, naive me.
I am starting to think that this thread is an example of "perpetual motion".
I like it richard.......so to keep the motion going, I beg to fifer Justin

It's just as common knowledge also that Boeing/ US government maybe testing the em drive on the X-37B.
If you consider that the transfer of information was back in 2007 and the 10 year anniversary/deadline is nearly up on that.......... then just last month Roger Shawyers patent for the device in the UK was published, I believe that's highly unlikely.

You can quote as many Eagleworks papers as you like, but that paper is the one that casts doubts on if EM-Drive actually works the way Shawer thanks it does.
During the test summaries they quite clearly point out that the thrust was likely due to CG loading due to thermal effects.
Important quotes
Forward test
"This displacement was also in the same direction as that due to the CG shift from thermal effects."
Reverse Test
"As the test article assembly was rotated by 180 deg, this displacement was also in the same direction as that due to the CG shift from thermal effects."
Null Test (device rotated to make any thrust detection impossible due to how the balance works)
"the CG shift from thermal expansion caused a downward drift in the optical displacement sensor."
In all cases the tests suggest that the thrust signal is caused by a shift in the CG of the device due to thermal expansion.
So no definite signal was detected.
In their conclusions they mention the thermal effects, and how to go about making sure any CG shift does not influence the balance.
As for the X-35B test Yeah I remember that excitement, however it turned out to be an improved standard Ion drive. I have a good friend in the field (actually he's a cubesat plasma thruster specialist) and he burst my bubble there.
I'm not saying the EM-Drive does'nt work, but I am pointing out that if it does work has not yet been confirmed, it's from the data gained by the experiments run so far there are a lot of doubts about its viability.

Could not find much info at all but tastes like snake oil!
Hey everyone. I'm Jeff.
I'm hoping to sell the race fairings I used on my Zero SR last year and Maria from Hollywood Electrics used this year. I am racing a different bike now and I don't use the fairings any more. These fairings are fiberglass race fairings for a 2008-2012 CBR1000RR. I had brackets made to adapt them to a 2014 Zero SR. These brackets will work on Zero SR, S, and DS from 2013-2018. The brackets include a mount for the upper fairing stay, a custom aluminum tail section, an aluminum stiffener for inside the "tank", and other small brackets to stabilize the fairings and mount the seat. Also included is a CBR seat and a windscreen. Installation requires installing a couple of threaded inserts under the seat but is straight forward. Changing from stock to race fairings takes less than 1 hour. The yellow vinyl stickers on the fairings have faded a lot from when I put them on but the fairings are in good shape with only typical wear from the few race weekends they were used for. These fairings were never crashed but Maria did tip over! She didn't damage anything though.
If somebody wanted to install some lights, these fairings could be used on a street legal bike. The fairings got a lot of attention and looked great on the Zero. More photos can be seen on the Hollywood Electrics Facebook and Instagram pages.
I would like to get $975 o.b.o for the fairings, windscreen, upper fairing stay, seat and custom brackets and tail section. Local pickup in the Los Angeles area is preferred because this would be a big box to ship. Make me an offer please!

I'm highly aware of the EM drive and have followed Paul March and Sonny Whites over at Eagleworks labs work on it as well, I find how Shawer interpreted the Eagleworks tests to be amusing at best...
That the null device produced an effect on the thrust balance was pretty much a fatal stab in the heart to the EM-Drive and a huge disappointment to me, as it basically invalidates Rogers interpretation of how the drive works. (This was the entire reason to build the null drive in the first place). It's generally suspected that the device is thermally heating up and producing false readings on the thrust balance, I'm aware of tests that are on going to confirm/rule out that possibility at the moment. But its notable that both the Chinese and Eagleworks have given up further research into the device at this time. There is also a very outside possibility that the EM Drive is exploiting an actual effect, but if so then their is a better way to do this (possibly) than the EM Drive, this effect is the so called "mach effect", its quite possbile that Shawer has accidentally created an inefficient Mach thruster, and is one interpretation by Paul March as to why the null device might have caused the thrust balance to register. However its not impossible that the EM Drive works how Shawer believes it does, its just not that likely either...
If you are really interested in propellentless drives, then I suggest looking into Woodward and Fearns so called "mach effect" thruster, which has a much better grounding in physics, and while still not confirmed as an actual effect, does look to be less of a bust than the EM Drive.

A long rambling argument over the feasibility of the Mach Effect Thruster.
https://forum.nasaspaceflight.com/index.php?topic=31037.0
As a final thought on the Mach effect. If it does work (still a big if) and if it works the way it is believed too (an even bigger if) then there is a really interesting consequence, in that it is in theory capable of generating negative mass. This is believed to be the critical ingredient for creating wormholes (again a big if here, as we don't know if this is actually true) if these three *ifs* are all actually true. Then we may actually be truely on the cusp of actual feasible (non FTL) interstellar travel. But I caution this is a *terribly* big IF (and if Stephen Hawking is wrong about radiation interference between looped wormholes collapsing the pair, then we are also on the cusp of Time Travel, though frankly I think that really is unlikely)
Yes, but Tesla hypothesised the universal force (ZPE?) was kinetic, and he did not say it was actually possible to extract energy from it, in fact he was quite agnostic on that front, which suggested he had no evidence on the matter. Not really a ringing endorsement.
Quote.if you read carefully I quoted Tesla
Hmm. Tesla was a gifted chap, but lived in a time before we really got to grasp with the details of Quantum dynamics, so his understanding of what ZPE entails was very limited, as such his views on ZPE are of periphery and generally historical interest only. Bear in mind the very early foundational models for ZPE was mostly developed in the 1930's only a few years before Tesla's death, and the most important breakthrough in demonstrating its existence occurred after Tesla's death.
Given the above, Tesla did speculate on the idea of a cosmic force that sounds like the quantum ZPE however Tesla did not know if a ZPE like effect was capable of producing work and he entertained the idea that it was incapable of doing so.
Its alright, I'm personally having a ball.
The worrying thing about people wanting stuff like ZPE generation is they haven't thought through the consequences of what it means if we do get it, and its open source and easily available.
Usable ZPE generators go hand in hand with concepts such as the EM-Drive which operates on similar principles, and when you couple generators which require no fuel with drives that require no onboard propellent. So let's say that both the ZPE generator and EM-Drive are practical, then, if you are sufficiently evil, then what you get a new class of weapon that makes nuclear bombs look literally like firecrackers.
While I could explain how increadably bad this weapon is.
Please allow scifi author's Charles Pelligrino and George Zebrowski to put it better than I ever could:QuoteIn the forests below, lakes caught the first rays of the rising Sun and threw them back into space. Abandoning the two-dimensional sprawl of twentieth-century cities, Sri Lanka Tower, and others like it, had been erected in the world's rain forests and farmlands, leaving the countryside virtually uninhabited. Even in Africa, where more than a hundred city arcologies had risen, nature was beginning to renew itself. It was a good day to be alive, she told herself, taking in the peace of the garden. Then, looking east, she saw it coming -- at least her eyes began to register it -- but her optic nerves did not last long enough to transmit what the eyes had seen.
It was quite small for what it could do -- small enough to fit into an average-sized living room -- but it was moving at 92 percent of light speed when it touched Earth's atmosphere. A spear point of light appeared, so intense that the air below snapped away from it, creating a low-density tunnel through which the object descended. The walls of the tunnel were a plasma boundary layer, six and a half kilometers wide and more than 160 deep -- the flaming spear that Virginia's eyes began to register -- with every square foot of its surface radiating a trillion watts, and still its destructive potential was but fractionally spent.
Thirty-three kilometers above the Indian Ocean, the point began to encounter too much air. It tunneled down only eight kilometers more, then stalled and detonated, less than two-thousandths of a second after crossing the orbits of Earth's nearest artificial satellites.
Virginia was more than three hundred kilometers away when the light burst toward her. Every nerve ending in her body began to record a strange, prickling sensation -- the sheer pressure of photons trying to push her backward. No shadows were cast anywhere in the tower, so bright was the glare. It pierced walls, ceramic beams, notepads, and people -- four hundred thousand people. The maglev terminal connecting Sri Lanka Tower to London and Sydney, the waste treatment centers that sustained the lakes and farms, all the shops, theaters, and apartments liquefied instantly. The structure began to slip and crash like a giant waterfall, but gravity could not yank it down fast enough. The Tower became vapor before it could fall half a meter. At the vanished city's feet, the trees of the forest were no longer able to cast shadows; they had themselves become long shadows of carbonized dust on the ground.
In Kandy and Columbo, where sidewalks steamed, the relativistic onslaught was unfinished. The electromagnetic pulse alone killed every living thing as far away as Bombay and the Maldives. All of India south of the Godavari River became an instant microwave oven. Nearer the epicenter, Demon Rock glowed with a fierce red heat, then fractured down its center, as if to herald the second coming of the tyrant it memorialized. The air blast followed, surging out of the Indian Ocean -- faster than sound -- flattening whatever still stood. As it slashed north through Jaffna and Madurai, the wave front was met and overpowered by shocks rushing out from strikes in central and southern India.
Its called a relativistic weapon, and if you don't have to worry about sustained power generation or on board propellant, they are actually quite easy to make (the reason we can't make them is because without the two aforementioned requirements, they are in fact nearly impossible to make)
Basically its a mass driver on a LOT of steroids, all you need to do is keep accelerating a chunk of iron long enough, something that a ZPE generator would make fairly easy...
So personally I kinda hope that ZPE generators are a bust, if simply because terrorists sure could have a lot more firepower with one...
(Tl:dr - Friends don't let friends have unlimited power generation and/or reactionless drives)
