I understand you believe that but he has had his peer reviewed and already published papers blocked by arXiv for example and stuff like so I don't think good faith applies here at all.

This article about his first DARPA funding https://www.plymouth.ac.uk/news/scientists-receive-13-million-to-study-new-propulsion-idea-for-spacecraft

I meant QI theory, that it has seen lot of headwind not this IVO company his been working with. I've been following Mike Culloch's journey through his tweets. He is politically on the right so his theory has been getting bit headwinds of because his political views. Which is sad because science so be matter on its merits not how scientists view the world. So if you follow him expect some right wing stuff as well ;) DARPA for example has been funding him as well so they at least they thing something might be there.
Of course company would get headwinds as well because if they prove theory is right then quite likely all that huge funding for dark matter will be gone forever.

Drive is based on Mike McCulloch's Quantized Inertia (QI) theory. It gets lot of headwind partly because theory removes possibility of dark matter and lot of people in science circles are affraid of losing their funding.
