Not to mention that the flames while combusing are invisible by sight. It’s also really difficult to keep contained and if it leaks it has ~11x the impact of CO2 per this article.
I used to like the idea of hydrogen as an energy medium but all of its attributes combined just make it really infeasible to use except for immediate applications.
We need better propulsion methods than Helium…
…but we don’t exactly have other lighter than air alternatives.
What about a really big kite?
Well, there’s hydrogen, but that has its own downsides. Like it’s a bit explody, for example.
