From this article:
"At 124.5 meters long, the [helium filled] Pathfinder 1 dwarfs the current Goodyear airships and even the massive Stratolaunch plane designed to launch orbital rockets. It’s the largest aircraft to take to the skies since the gargantuan Hindenburg airship of the 1930s."
"An MRI can’t function without some 2,000 liters of ultra-cold liquid helium keeping its magnets cool enough to work. But helium — a nonrenewable element found deep within the Earth’s crust — is running low, leaving hospitals wondering how to plan for a future with a much scarcer supply."
@Frances_Larina Sounds like a great idea if helium were abundant… otherwise just another project by people who have so much money they don’t know what to do with it. What I love is that its clean power is by “Twelve electric motors powered by diesel generators and batteries.” Diesel is such a ‘clean fuel’ 😮
@Frances_Larina Essentially. Mind you, where I live electric cars are mostly powered by coal because it’s what produces the better part of our electricity. And as demand from electricity goes up from an increase in electric cars we will need even more coal-produced power because we’re already struggling with too much demand from the grid. I see birds fly, squirrels run their entire lives, all without coal, oil or nuclear power. Yet we claim we are the most intelligent.
