Presumably you wouldn't want to use something that violently catches fire (sodium) in a vehicle designed to tolerate nearby explosions.
- hliyan 3y agoAlso a vehicle that is immersed in a liquid that violently reacts with it.
- acidburnNSA 3y agoPresumably. The USA did build a sodium-cooled submarine at one point, the Seawolf. Having high thermal efficiency increases range, and liquid metals can be pumped electromagnetically and completely silently, with no moving parts. It was converted to water coolant later due to technical challenges though. https://en.wikipedia.org/wiki/USS_Seawolf_(SSN-575) https://en.wikipedia.org/wiki/USS_Seawolf_(SSN-575)
