Don't get me wrong, it's definitely interesting that this thing keeps making headlines after all these years, but if the drive is capable of the kinds of thrust they say it's getting, why haven't they been able to prove it beyond a shadow of a doubt? Every space agency and their dog would already be sending prototypes into orbit if they didn't think that this was a scam.
If I read it correctly, an image of one of the slides says that it has been confirmed by 2 independent parties.
I kind of understand space agencies not trying these out. They are government funded with tight budgets. If they chased all of these and only 1% panned out, they would get lambasted by their ruling bodies as wasting money. Also where the inventor can’t explain how it works, it would make it really hard to support with the reliability we want in stuff we send to space.
"Since the reported thrust was on the level of a merest fraction of a Newton,"
Yea anything like this cries measurement error or unconsidered factors. What I find hard to understand is how often experts in their fields are the ones claiming these advances.
