We need better propulsion methods than Helium...

...but we don't exactly have other lighter than air alternatives.

    Well, there's hydrogen, but that has its own downsides. Like it's a bit explody, for example.

    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.
