So I'm wandering, if you had a bike pump and pressurized it, at what pressure would you need to get it up to 212 degree and how long would you have to hold it to kill viruses? I would think the heat in the tank would convect out to the open air quickly once you came up to the temp/pressure not giving enough time to kill pathogens.That would probably be where vacuum jacket would help, but would crush under pressure. Force=Area(in Square inches)X Pressure. It would be interesting if you have a laser thermometer and measured the outside wall as you brought pressure up, and looked at how fast it dissipated.
