True. But the photon thrust is 360 times less that the measured output here. And this is with an experimental device. That is a big deal.

I’ve been following McCulloch’s work and its completely in keeping with what my college relativistic physics prof taught – that inertia is approaches infinity at light speed, and that mass becoming infinite as it approaches the speed of light is a myth. That McCulloch has placed this concept in a theory that seems to explain concepts from the EM drive to being able to describe galactic movements without the need for dark matter is actually an even bigger deal. That the EM drive can be predicted with his theory seems to give it credence.

That said, people keep trying to kill off the EM drive, and it hasn’t happened yet. Cold fusion was killed off much faster. I say we give it time and see what happens.

Under ideal condition you can produce 1 Newton thrust by application of 300 MW (or 1 Milli-Newton by 300 KW, or 1 Micro-Newton by 300 W). So EM drive looks not very strange.

Even if the EM drive is only producing 2% of the thrust of a hall drive, it doesn’t need mass. That is a big deal. Station keeping, exploration, all open up.

You should check out the physics from the edge web site. Its interesting that he has developed a theory that flushes dark matter and seems to predict what the em drive is doing…

Would they produce enough thrust for this purpose?
