Saw the saddest thing in the world today: party balloons peeking out over the top of a dumpster.
I started thinking about the buoyancy of H versus its flammability. H is 6-7 times more buoyant than He. It would be more more economical to use H if we could eliminate the explody bit.
If you can find an expedient way of keeping them from separating, could you mix He with H sufficiently that the H could be rendered non flammable? What concentration of He mixed with it might make the H non flammable?
(Is my logic here correct? Fuels like propane gas need a sufficient concentration before they will ignite. Is it sufficient to keep the H diffused in an inert gas so that it will not explode in the presence of oxygen and a spark?)
