Posted by miljacEV on April 23, 2008, 10:39 am Please log in for more thread options is it possible to buy somewhere a small steam turbine? with minimum efficiency of 30% and power ratings from 1kw to 5kw. i am not intrested in DIY. tnx Posted by on April 23, 2008, 11:12 am Please log in for more thread options > is it possible to buy somewhere a small steam turbine? > with minimum efficiency of 30% and power ratings from 1kw to 5kw. > i am not intrested in DIY. I'm interested as well, but in a smaller size: 1 Watt would be plenty. What I want to do is set up a small steam-powered generator to recharge batteries while camping. I'm thinking of using an old pressure cooker for the boiler, along with a steam engine or turbine to power a dc generator of some sort. I want the whole thing to fit inside the pressure cooker for easy tranportation to the campsite. The output would be directed to a standard 12 volt car-jack, so that I could plug in anything that uses a car charger. Is this a foolish, hare-brained scheme? Or might I be able to put this together and have some fun with it? Specifically: I've looked at miniature steam engines on the 'web. I find none with any output power measurements. Is that because those little steam engines produce almost no power? I'm thinking that using a DC motor as a generator might work. What kind of specs should I look for in order to find a suitable motor? Will this be all trial and error, or can I calculate the suitability of the engine and the motor using their specs? Am I barking up the wrong tree, thinking that I can mate a small/light steam engine or turbine with a DC motor or other dynamo to charge up my cellphone? I hae no "feel" whatsoever for the power output of miniature steam machines, nor the torque necessary to get useful output from a small DC generator. Anybody got a seat-of-the-pants asessment of this idea? -- The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts.         -- Bertrand Russel Posted by sno on April 23, 2008, 11:45 am Please log in for more thread options EskWIRED@spamblock.panix.com wrote: > > > is it possible to buy somewhere a small steam turbine? > > with minimum efficiency of 30% and power ratings from 1kw to 5kw. > > i am not intrested in DIY. > > I'm interested as well, but in a smaller size: 1 Watt would be plenty. > > What I want to do is set up a small steam-powered generator to recharge > batteries while camping.

Their featured product is a cute little model power plant, complete with a steam engine and an AC generator, which lightsup a cute little LED lampost. That is what made me think that little steam engines may be wholly unsuitable. The rest of the sites I get from the Google search seem similar: Cute little models with no specs for output. IOW, toys. Which makes me ask my threshold question: Does anyone have a "feel" for this? Is it maybe workable or definately foolish? -- The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts.         -- Bertrand Russel Posted by Vaughn Simon on April 23, 2008, 4:43 pm Please log in for more thread options > definately foolish? In my opinion...totally usless. If you want to charge batteries while camping and you don't need much power, think of solar. If you need a bit more than that, get a small generator (make it an inverter generator if you can afford it). You could possibly run the generator just an hour or two a day to charge a battery, but it depends on your power consumption. Vaughn Similar Threads Posted EskWIRED Still looking for a Steam Turbine?
