Never mind all that. How much wood could a woodchuck chuck if a woodchuck could chuck wood?
So the members of One Direction are really woodchucks?
I thought that was mackerel-more

Yet more fusion talk:
In 20 years--no...we mean it this time...
Now, I was matching Nat Geo's Mars.
I wonder if inflatable wind blades may be light enough to use in a dust storm--maybe a way to harness static...
What is the lightest fusion reactor that can be built for the output required? Would it be practical to launch into orbit? Could it be assembled on orbit?
My guess is that--even if this pans out--it is still going to be like an ion engine--something that has to be built in space.
Right now--folks want to combine both nuclear electric and nuclear thermal:
So an EM drive might look like that--just with frustrums in place of the NEP bits

An article with a critical review of "the paper" concludes with this:
I would add that anything similar to the phrase "breaks the laws of physics" is hype because physics defines itself. We don't fully understand something or there are physical laws yet to be discovered. We don't define the laws by popular vote. We merely observe and use them. Anything that expresses breaking the laws of physics is reporting, exposing or counting on ignorance.
The point made that the device should be tested in a much larger vacuum chamber to help eliminate interaction effects with the environment is valid. Perhaps the large vacuum chamber at the Space Power Facility at NASA Glenn Research Center's Plum Brook Station in Sandusky, Ohio could be used if no space-based testing is feasible or too expensive?
If the device is proven to work, it would demonstrate that linear momentum is not conserved and would likely open up vast areas of research -- can the laws of conservation of angular momentum and energy similarly be overcome? If the device works against the vacuum field, it implies that space-time is not Lorentz invariant and that a preferred rest frame might exist. It might also explain why the Universe appears to be dominated by matter rather than anti-matter.
Or local inequities will be compensated by nonlocal consequences.
By the way, there was recent confirmation that a hydrogen atom has exactly the same mass as an antihydrogen atom.
Gravitational mass or inertial mass? I assume the latter. The two seem to be the same for matter but one shouldn't assume equivalence for anti-matter on that basis.
I've seen electrical equipment jerk when turned on--this might be all this is.
I wonder if this can be used in any way:
Probably as much use as the snake in my boot.
Everybody knows snakes are for planes. In fact, I can just see a sequel film now: "Snakes on an EMDrive Ship".
PBS Space Time finally makes an episode about the EM Drive, including addressing Pilot Wave Theory:
