Is this the new Clippy?
This is a company that used to be a part of GM and when GM spun it off into its own business they used it as a way to jettison all of the most useless members of upper management. These folks ran the company into the ground in a very short amount of time and then went through the longest bankruptcy in US history.
There have been a number of really cool products that they were developing that they inexplicably shelved, so I won't be surprised at all if they get this working really well and then decide to pack it away and never do anything with it.
It's also used in the aerospace industry a fair amount.

Perhaps I should have been more clear. I think it's a bad unit to use, because it's being used to purposefully scare people. The large order of magnitude of the measured values is misleading. Saying 1 Trillion Becquerels makes it sound a lot worse than it actually is.
While it's not a good thing, using Becquerels is a convenient way to make something sound worse than it actually is. It's 27 Curies, which is about 0.18% of the activity of the sources they use for some gamma sterilization machines (which can be around 15000 Curies or 555,000,000,000,000 Bq). Now that is a scary amount of radiation.
Something something...Magnuson–Moss Act has nothing to do with being able to buy aftermarket parts. It's about warranties.
Some friends of mine did exactly this as a research project last year.They did some testing at NASA Langley using some of their low pressure testing facilities.
It should be possible in a few years for sure and it may even be possible now. That being said, it's quite possibly the least efficient way to do anything anywhere, especially so on Mars. The rotor blades have to be enormous in order to generate enough lift. They also made some assumptions about materials used that aren't realistic right now, 5 years from now, probably, but not right now.
You definitely weren't hearing sonic booms from a B-52! It's max speed is 650 mph which is a whopping
That being said, B-52s are really loud and their engines do have a very distinct scream.
