Liquid Helium Pumps
- ioquatix 10y agoThere is a nice documentary about the search for Liquid Helium. https://www.youtube.com/watch?v=NzYdo1xEbQo https://www.youtube.com/watch?v=NzYdo1xEbQo
- kough 10y agoNot sure what prompted the post, but this reminded me of one cool use of liquid helium: as a scintillator for particle experiments. Huh, I was going to comment that SNO+ was planning on using a mix of liquid helium and argon for its scintillator, but after checking the site it looks like they've switched to linearl alkyl benzene (http://snoplus.phy.queensu.ca/About.html http://snoplus.phy.queensu.ca/About.html). Guess things have changed since 2012!
- maxander 10y agoRegarding what prompted the post, its probably not coincidence that the subject of liquid helium pumps came up in a Worldbuilding Stack Exchange question earlier today: http://worldbuilding.stackexchange.com/questions/70788/how-could-a-submarine-like-vehicle-steer-and-propel-itself-in-a-superfluid http://worldbuilding.stackexchange.com/questions/70788/how-c... .
- Create 10y agocern is recruiting scada (hv/lv) control disposable temp technicians through astrotrufing. see other post. their pr and tv studio(!) is bigger than some experiments. now that a grain of salt has been handed over, go ahead and downvote as usual
- ridgeguy 10y agoThis company also made the turbopumps for SpaceX' Merlin engine [1]. [1] http://www.barber-nichols.com/products/rocket-engine-turbopumps http://www.barber-nichols.com/products/rocket-engine-turbopu...
- GregBuchholz 10y agoWould have been more interesting if we were looking at a liquid helium fluidyne engine. https://en.wikipedia.org/wiki/Fluidyne_engine https://en.wikipedia.org/wiki/Fluidyne_engine
- guard-of-terra 10y agoI wonder if they ever tried mounting one of those on top of CPU.
- aunty_helen 10y agoIs this theoretically possible? Wouldn't the 'working gas' liquify since you're pumping LHe?
- peckrob 10y agoThe story of the hunt for liquid helium is one of the more fascinating and colorful stores I've read. The blog Damn Interesting weaves the story pretty well. https://www.damninteresting.com/absolute-zero-is-0k/ https://www.damninteresting.com/absolute-zero-is-0k/
