Pulse Jet Engine Powered Bathtub Boat

White pine County Rec. Ely Nevada Cave lake Bathtub Races Summer of 2010.
My entry was a Lockwood Pulse Jet Engine Powered Bathtub. Just burning off some excess propane. And entertaining the crowd.

For more information about future tub race's. Call the Ely's, Bristlecone Convention Center at: 775-289-3720

Dear Santa...

@johnny1bucket Their be no guessing having this land on your roof ?!?!?!?!?!?

[55dcyinely]

@johnny1bucket No melting! It would just stop working. And that is the down side of a Pulse Jet, you can't combined it with (or as a pair) anything as functional engine. It would how ever if submerged in water create steam.

Thanks for the reply, I hadn't realised you answered the exact same question in a previous post, sorry for being dumb!

[55dcyinely]

@landyladv8 It's cool! Build a bathtub boat and join us next year in Ely's bathtub boat race.

-43 F == -41.7 celsius.

Do you mean propane gas will condense and boil at such cold temperature?

[55dcyinely]

@Austyg So, Propane is Condensed into a -42° Fahrenheit Liquid until we make it boil and release it as a gas to BBQ.

[FreedomRebel]

won't it melt without cooling ???

and can't you combine this maybe with a steam boiler for extra power & cooling...

or even a peltier element to generate electricity ?

That gas cylinder's getting nice and warm

[Georgieisaporgie]

I wanted to see it cool down ):

[55dcyinely]

@Austyg (NO! it looks to boil like water at 212° Fahrenheit.) Both BOILING AND CONDENSATION points assume a standard of 1 Atmosphere unless otherwise noted. A 20 gallon tank of propane at 70° Fahrenheit the liquid boils and turns into gas the pressure will be 109 PSI, another at 80° Fahrenheit the liquid boils and again turns into gas the pressure will be 128 PSI. See a trend? Temperature is the key factor! Lower temperatures the less the pressure is. And “Vice Versa”
