Re: Idea
Incidentally, this is why helium is a rare and valuable resource on Earth, despite being the second most abundant element in the universe, and why we shouldn't be wasting it on party balloons
Helium is obtained from natural gas extraction; sticking it in party balloons might be "wasteful" in a strict sense, but pretty much the only other option is to just vent it, which is wasteful by anyone's definition. And even when we do run out of dead dinos, helium's a natural product of radioactive decay; pass alpha particles through a long enough pipeline to eliminate beta and gamma radiation and you've got a perfectly serviceable production line.
