Boom doesn’t actually have a turbine yet. Their design partner publicly pulled out of their contract with Boom a while ago.

Boom has been operating on vaporware for a while. It’s one of those companies I want to see succeed but whatever they’re doing in public is just PR right now. Until they actually produce something (other than a prototype that doesn’t resemble their production goals using other people’s parts) their PR releases don’t mean a whole lot.
