There's only one way to prove this thing works... get Musk to send one up.

The thrust is so ridiculously low that there's no way to know if it's working or not. And even if it produces thrust, chances are it's just going to be one of the many sources of measurement error, and not any "real" effect they're trying to prove the existence of.

That's actually why they need to test it in space. Once it's in orbit its not going to change its trajectory. You turn it on and leave it be for a while. Over days, weeks, maybe even months you watch its orbit. If the orbit is changing you know there is a non zero thrust occurring which would be fucking crazy.

My scientist friend explained to me that it's cheap acceleration that is exciting. Low thrust is a non-issue.

thats because thats not the kind of ship engine this is

this doesn't go fast, but it runs cheap and builds up speed slowly. slow acceleration building over time adds up to higher speeds total in zero gravity, then a short period of fast speed

There's absolutely a way to know, when the thrust causes the object to change course or slow down, two things that don't happen in space without an outside influence acting on it.

LOL. He cant even deliver on production , itll never get done
