But the thrust can still be seen, and engineers still can’t explain what’s causing it.
If it becomes operatonal, the EMDrive propulsion system would permit travel at speeds until now only seen in science fiction.
But here’s my entirely ignorant prediction.
They need to weigh the drive. Accurately.
The thrust is coming from atoms (molecules? Protons, whatever) being knocked off the outside of the chamber by whatever is happening inside it. These are very few, but moving at relativistic speeds. Thus the thrust.
In effect this is a very inefficient ion drive. As such it won’t work for long distances as with long distances there won’t be a drive there.
Yep, I know nothing about this at all but as Ritchie would say, go on, prove me wrong! Thus I must be right, eh?
