Helium is a non-renewable substance which there is a global shortage of. I wonder how much it takes to lift that thing 😅

Wouldn't hydrogen be better for lifting something like a wind turbine.

Yes, but I think hydrogen likes to go bang 🧨💥

No worries, that only happens if there's a spark, like for instance some static electricity. Shouldn't be a problem here, surely this thing won't generate any of that.

[-] GreenShimada@lemmy.world 3 points 1 week ago

Not necessarily. It's not about the boom factor alone - hydrogen is a small atom, and so under pressure, most commonly used materials are permeable to it. It leaks through every material. It really takes something as solid as steel pipes for hydrogen atoms to not work their way through and escape. So while hydrogen would be cheaper to produce at scale, it's also constantly leaking out of any container.

For wind turbines, static electricity and storms would be huge risks as well, so the application of a floating wind turbine would not be ideal.

Yeah, that's what the folks who designed the Hindenburg thought as well.

Helium may not be renewable but we can manufacture it from things like boron

Not once we get fusion reactors up and running, then we’ll be drowning in that sweet sweet helium-4
