Man builds a working hoverbike

[Duke]

Government: "Wait, this thing doesn't take gasoline?"

Inventor: "No."

Government: "So we can't make money off of this?"

Inventor: "Naw."

Government: "Sorry, can't use it. It's unsafe."

This isn't so farfetched, because supposedly there was a person who invented an engine that could run on water & guess what the government did???
