Many traditional ships had ballast,the old galleon had rocks,the viking long ships had rocks.Carrying rocks as ballast till you loaded up with cargo,is still...
Test this outside so you don't burn your house down and stand way back so you don't end up dead or maimed. Steam can be seriously dangerous. I do this for a...
Btw, if you're going to try to run it on low pressure steam it'll take a HUGE quantity of it to make the engine run. You still need a huge boiler to provide...
... I did that. My parent model was a beamy, double ended boat with a deep V. Equivalent to a small boat with a beam of 4 feet, length of 8'10", draft of 2...
Yea he showed me that different boat with different dimensions have different quantities . Is that what you got from it Jon? Or did it confirm that all ideas...
... With "sharpie" being an undefined term now-a-days ... The original sharpies were quite narrow, and could slice through the waves. The story I hear from...
Doug: I can't help but wonder if a hot air engine (stirling) would be better for this application? The reason steam went to high pressures is because a low...
Does anyone know if Bolger's Illinois design has ever been built? This page <http://www.hallman.org/bolger/Illinois/> , an excerpt from MAIB circa 1998, says...
T. a "sharpie" is and will allway be the classic New Haven model. It has known dimensions , attributes , and sailing qualities. They were uses for oystering...
So, take a wild guess at the number of boats in the world that have engines. Now, gives us an estimate, in percent, of how many run their engines in the ...
... Youre right of course but I was not referring to the site being green but the fact that it is running off of low pressure steam and that I am not the only...
... So is sailing in the ocean, sky diving, flying small planes etc. I'll bet bill in spite of all you're steam knowlege you don't know much about low...
... I am setting in Bridgewater Va. where we have a lawn party every year. There are 20 or thirty steam tractors running off of 30 psi because that is the...
... This is not a matter of practical, it's a matter that some people want to play with steam boats. A hot air engine is not a steam engine so it doesn't fit...
... Highly unlikely, if it had, we likely would have heard of sightings. Interesting concept, it could make a nice 'vacation' or retirement platform for about...
30 psi is not 5 psi and look at the size of the boilers, they are huge. It takes a very large amount of surface area to generate enough volume of steam to do...
Btw, there is nothing at all wrong with a steam engine boat, I know a couple guys that use theirs all the time and they are very cool. But they both bought...
Forgot one important thing. Every state has regulations reguarding boiler construction. Do yourself a big favor and look at these before you actually build...
High pressure steam doesn't necessarily mean using a boiler. For small engines especially it makes more sense to use a "flash" or once-through steam generator...
It's long past time to realize that all forms of energy impact the environment, it's a question of how much and in what ways. Can you extract enough solar...
... I under stand a lot more about making steam the some might think. For example I know how much heat it takes to convert a gallon of water to steam at 5lbs...
The boiler by itself doesnt' generate any hp, the engine the boiler drives does. There are far too many variables to give a simple answer. Do a web search for...
Well, so be it. Yet surely there's some means used to size one to the other, the boiler to the intended use. I suppose the method involves taking into...
