But I wondered, if we added to the "Feedstock list" (Electricity & Deuterium) a gas like Uranium Hexachloride, could some applied physics experts get the Particle Collider to work in less of a vaccum & at hotter temperature ?
Nearly all the helium
on Earth is thought to be from the natural decay of uranium and thorium, but the amounts of these radioactive elements is huge compared to the amount you could put in a machine like a particle collider.
You could get small amounts of helium from nuclear fission reactors, but I think (From the lack mention of it in literature, not from doing calculation) the amount is so small that it’s not worth building the reactors to do it.
Hydrogen is unacceptable in our current hyper-medicalized, hyper-comfortable, and hyper-safe societies. And I think it's kind of a good thing overall...but limiting in some ways.
You got to give people, investers, insurances etc a gas that does the job and never explodes.
I don’t think hydrogen is unaccepted worldwide, just more limited in its applications than some people wish. For many years, it was considered a promising alternative to petroleum fuels and electric batteries, but since the cost of petroleum has remained low and the cost, energy density, and lifetime of batteries improved, burning hydrogen in engine
or using it in electricity-generating fuel cells
, both mature but expensive technologies, hasn’t gained much popularity. Hydrogen remains a popular fuel in high-performance rockets, like the upcoming SLS
, but outside of rocketry, seems to me to be limited to , like toy rockets
and emergency power supplies
The danger of hydrogen gas is IMHO mostly a myth, due mostly to the spectacular 1937 Hindenburg disaster
. At atmospheric pressure, burning hydrogen produces about 1/3rd the energy of burning methane, so doesn’t produce as much heat or explosive energy, so hydrogen gas fires are among the least dangerous. The Hindenburg fire, for all its infamy and spectacle, killed only 35 of its 97 passengers and crew.
Me & you can agree, other people may not. It's not a bad thing, take it as a challenge...
Some people say that if the Gasoline Engine Car was invented today, it would be judged too dangerous & maybe even forbidden regards current legal policies BULLSHIT ! Everything's freaking forbidden now.
I’m not aware of any laws in the US forbidding experimenting with various kinds of engines, surface vehicles, or aircraft, as long as they’re done on private land and don’t endanger aircrafts. Laws and regulations become a major time and money expense when you want to use new machines on public roads, sell them, or carry passengers.
God bless America, and Helium Airship Transportation for Civilian, Military & Rescue applications !
While there are some cool modern lighter-than-air airships, like especially the semi-rigid Zeppelin NT
, I don’t think airship, which these days are of value mostly as advertisements and for sightseeing, have much of a future in transportation, militaries, or rescue.
Airships are inherently slow – The USS Macon
, lost in 1935, cruised at 63 and maxed at 87 miles/hr, while the Zeppelin NT cruised at 71 and maxes 77 (though its highest officially recorded speed is 69.6). Though capable of carrying cargo comparable to modern cargo aircraft – the Macon could lift 152,644 lbs, which fully fueled was 100,000 fuel + 52,644 payload, about half of a Boing 747-8
’s 500,000 = 378,200 fuel + 121,800 payload – with about 2 times the 747’s payload/fuel efficiency, an tractor+trailer road truck
can haul about up to 38,000 = 2000 fuel + 36,000 payload at about the same speed, with nearly 6 times the airship’s efficiency. A railroad train
is even more efficient, about 4 times as efficient as a truck.
The only way I can imagine airships successfully compete with trains and trucks is if there were many people someplace with few or no high-speed rail or paved roads. The only scenario I where I can imagine this happening is some sort of Mad Max
-esque collapse of civilization where rail and paved roads are desroyed, but somehow the technological and manufacturing infrastructure to build airships survives.
One application where airships may shine is as alternatives to communications satellites
. Another is for a few very heavy-lift airships like the Aeros Aeroscraft
