We'll see if this is real or another 'cold fusion' story......................

I am skeptical of what a modified microwave can do here.
I suspect an idea that is begging for money / funding.

Kirk: Spock, where the hell's the power you promised?
Spock: One damn minute, Admiral.

Who needs that when you can just use your Interrositer?

“The microwave cavity thruster as set-up by Tajmar continues to violate momentum conservation and thus does not work as advertised,”

This strikes me as a "no true Scotsman" fallacy.

I was really looking forward to that 18 month slog to Pluto!

But...it has graphics.

Physics question for those smarter than I am (can you say everyone?)

Newton's Law - for every action there is an equal and opposite reaction.

Given that, wouldn't the top speed of any interstellar craft be limited to, or less than, the speed of whatever is coming out of the tail end of the craft?

Asked another way, if you have a rocket, in a vacuum, with an exhaust speed of 15,000mph, would the rocket be able to travel faster than 15,000mph?

It`s true.
When I turn on my microwave, the flat round thing inside goes `round and `round and never stops until I turn it off or set the timer.

They are skeptical and rightly so until one of these things gets off the ground which may well happen. It is about time in the technology evolution cycle for such a breakthrough.

“The microwave cavity thruster as set-up by Tajmar continues to violate momentum conservation and thus does not work as advertised,” says Eric W. Davis, a Senior Research Physicist at the Institute for Advanced Studies at Austin.

What hogwash. Sure, it appears to be in violation of conservation of momentum, but if it works experimentally, then obviously that is not an impediment. Perhaps the law is not actually violated somehow, or the law is not as inviolable as we suspected (if the device works).

[Moltke]

Not confirmed? Well, so much for the V3.

[Rockingham]

Funny that you mention cold fusion because physicists here and abroad are again working on it, both experimentally and in search of a sound theoretical framework. A practical cold fusion device seems to have been invented and to have passed several third party verification tests. The rights were purchased by a North Carolina investment group and an initial production run is expected soon, with the devices used to provide hot water for large commercial applications. A comprehensive peer-reviewed paper by outside experts is also said to be in preparation.

I think that the EM Drive may move along a similar path but at a more rapid pace. As positive experimental results accumulate, they will be disputed by naysayers. Yet, assuming that the science is valid, preliminary working devices will soon follow and be tested in orbit, by NASA, and perhaps the Chinese, the European Space Agency, the Russians, and the Indians. In addition, tech titans Google and Apple are both sitting on immense stockpiles of cash and aching for new tech fields to conquer.
