Hello everyone,

I mentioned the idea sometime in august of possibly building a steam powered bicycle and I was curious if there were any small high pressure steam engines whether designs or preferable casting or complete engines around?

Most if not all small engines only run at 100-150 psi like stuart, PMResearh and others yet if there were any that could run at much higher pressures 500-600 psi it would definitely save on steam consumption. I've read that the field steam bike run at around 600 psi. Could any of these smaller engines be adapted for higher pressures?

I think these smaller engines now that I have my steam bike are very much capable of higher pressures then they say, definitely not 500-600 psi, but I was running my stuart sirius on my steam bike at 225 and looking at a pamphlet of information I received with the bike. The primary steam automatic runs at 250 and the secondary one's supposed to go off at 350.
