Hi I have a question about a steam engine, is it possible to make a system where a steam engine could power an alternator by using a condensing method to condense water from the air and put the water on
a hot plate to vaperise it and use it as steam and make the steam go into a designed engine
which using steam engine tech you turn the alternator to produces eletricity??

Would thiat be efficient??

Like I mean would it take more or less energy to do such a thing since your condesning water vapor's to water, and then back to water vapor's.

I was just courious .

Sure. It´s possible; however, there are losses (entropy) in both the steam engine and the ¨alternator¨ (generator) as well as in the heating elements for the hot plate.
It is not efficient under ¨normal¨ conditions.

ok, then if you turned the alternator with magnet's not perment but ones what using current meaning eletricity, would that be more effecient, if I can get in at leas 50 rpm ??

just an example and hear of such a thing.

The reason I ask these question I wounder and saw a guy in navada making a wind mill that produces eletricity and that can condense water and use the water vapers that turned into water into drinking water.

what this prinicpal or tech be more efficient than using steam engine??

[zmike1]

With your new idea, the alternator has become a motor and the condensing water vapor is effectively a compressor (read air conditioner), which, of course, is known technology. Perhaps I don´t understand what you are saying. Perhaps some reading on carnot cycles and thermodynamics would help.

Hmmm maybe?? I am trying to have a generator run one water from the air and able to power up

a computer, that's mainly what I am trying to do.

ya I want to try use air condesioning to cool the air to a point where water vapor's or also can be called humidity, to be as water and then the water would be headed back into vaper to turn or run a small generators to products 12v .

but I have been told that it's not the best way becuse you will use more energy to do such a thing,
they say that your input is alway's more than your output.

Their was a guy that made a windmill the fans were made close to what a airplanes wing is and it has a place on it where it cools the air and creates water then used to provide water for the home even in the desert.

they guy tested it in cali and also navada and works, the wind mill te blades on a clam day has a rpm of 50

he said that he can power the aircondesioner and also the home and the pump to shoot the water down in a hose to the water pipes of the home.

I was trying to use that concept in my computer , just courious ect.
but instead of wind I would use steam, to turn a generator to produce power to my computer.

Really have a whole summer to do somthing so I want to do something productive other than play videos games.

I want somthing that if I monkey with it I will at least learn somthing out of it.

But I will search on google for that I have seen some stuff on thermodynamics.

Hi, I think your machine would be a bit complex and not efficient. First of all, you want to condense the water (humidity) from the air... to do so, you will have to refrigerate the atmosphere air and you will need lots (I mean LOTS) of condensed water to use it in the hot plate (because you are going to need to heat that water over 100 ºC, to produce enough pressure and mass flow to move the engine).

That engine, would be an "external combustion" engine. That's because you must heat the water before it goes into the machine.

Between al those process, your system will loose a lot of heat (pipes, etc.). That lost of energy causes the positive variation of entropy...

Hope you found this explanation useful!! ;)
