Scientists unveil fire-safe fuel
UC Riverside chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn’t react to flames and cannot start accidental fires during storage or transport, it is a “safe” liquid fuel.
for anyone not wanting to read the article, it's bmim perchlorate, and works because of very low vapor pressure
there's gotta be many more ionic liquids like this
actual article: https://pubs.acs.org/doi/10.1021/jacs.3c04820 supporting info has some details
I'm really interested to know what the environmental impact of this could be compared to conventional fuel sources
