user134450@feddit.deto World News@beehaw.org•The U.S. just sold its helium stockpile. Here’s why the medical world is worried.English6·2 years agooh i must have missed a few orders of magnitude there. 6Mt of helium is a ridiculous amount though … what is all that used for? according to WA that is about the water volume of the three gorges dam at STP
Edit: just read the report, wow, more than a quarter of all the helium is used just for “breathing mixes” which i assume means its for scuba diving.
user134450@feddit.deto World News@beehaw.org•The U.S. just sold its helium stockpile. Here’s why the medical world is worried.English6·2 years agofrom the wiki article on Helium:
an estimated 3000 metric tons of helium are generated per year throughout the lithosphere.
I think the main issue here is not that we are loosing helium on a planetary scale but that the easy to reach helium from gas wells is wasted. We will never run out of helium at our current rate of consumption before the sun goes nova, if we consider all sources on earth, but it will get a lot more expensive and the supply will get less steady.
”nitrogen-rich fossil fuels that feed our culture“ wow this article is really badly researched. the problem is of course real and has been described very well by William Crookes in 1898. The answer back then was the development of the Haber-Bosch process. The input was originally hydrogen from coal not natural gas which shows that the process is a bit more adaptable than this article makes us believe.
hydrogen can be obtained from many sources (including as a pure substance from wells as white hydrogen) and the reason why we use natural gas today is because it is much cheaper than the alternatives, not because other source materials would not scale as well.
how we will be creating inorganic nitrogen fertilizer in the future is a question to be solved but it is not an insurmountable problem – more like an upcoming shift in our economic practice because we will have to switch to more expensive sources.

woah this is awesome!
maglevs need classical wheel systems anyway because there might be a power outage, so simply having wheels that are compatible with the local rail system is a brilliant idea.
add in a tiny propulsion system so they can use the normal tracks at low speed without the help of the maglev tracks and you can sort of blend the two systems together in critical locations like switches and train stations.
