Years ago there was a city bus somewhere that ran off of hydrogen. They used liquid in a dewar, so it boiled off some every day. At least you don't have a pressure issue. -Original Message- From: dmmoff...@gmail.com Sent: Friday, November 4, 2022 9:25 AM To: 'AnimalFarm Microwave Use

Yeah I found a source on the web saying it's compressed to 3600-10,000 PSI in a vehicle fuel tank, but not stored as liquid because it has to be chilled to -270c to become liquid. Still, any gas at 10,000 PSI sounds scary. A punctured tank would decompress like a bomb. If there's an ignitio

I don't think it's practical to liquefy it for hydrogen cars. At higher temperatures, it's easier to make seals that work. bp On 11/4/2022 8:30 AM, Nate Burke wrote: But don't they have cars that run off Hydrogen?  Do they all leak too?  I could be driving along next to leaky H-bomb on wheel

Hydrogen is hard to seal because (1) it's the smallest molecule, and (2) It needs to be ridiculously cold to liquefy. That said, it is the most energy-dense of the options. but it's also why SpaceX uses kerosene or methane. bp On 11/4/2022 8:12 AM, Nate Burke wrote: I've only been reading ar

I've only been reading articles in the local paper, why are they having such a hard time plugging the hydrogen leaks? Back in College I worked at Argonne labs, and we used lots of helium/nitrogen for cryogenics. I don't remember having leaking problems. -- AF mailing list AF@af.afmug.com htt
