Closed loop low Boiling point steam engines

Here is an animated representation of the idea:

As for its practical applications:

-I believe that this device coupled to any internal comustion engine could produce power from the engines exhausted heat waste thereby making the engine more efficient. When coupling this closed loop system to a combustion engine I would imagine gearing it in a 10 to 1 ratio so that the steam engine creates less friction on the main engine while the system heats up and then provides more tourque when heated. The best expansion liquid I could find for this was for this CFC-113 chemicly known as Trichlorotrifluoroethane. Its critical temerature (417.4F) is optimal for carbon fuel exhaust and its boiling point (117.7F) is high enough that a quick moving wind on a radiator/condesser can reliquify it rapidly. For home generator purposes I would assume a large volume of water a few feet deep in to the groud would be able exchange heat quickly enough to sustain itself.

-Most importantly is its near solar applications to marine travel. Most of the oceans water is well below 70F but the deeper you go the colder it gets until it nears 34F several thousand feet under the ocean. By using this natural temerature difference to drive these closed loop piston systems one could provide electrical or mechanical power. The best expasion liquids I have found for this application have been Acetaldehyde (CH3CHO)and CFC-11 (Trichlorofluoromethane). By exposing the gas to dirrect sunlight while it is contained in slim black ultra heat conductive panels the liquid will vaporize, and exposing the condeser to the ocean will condense the vapor to a liduid.

If anyone has any input, questions, or other refrences on safer luiquids that boil at room temperature, please share any info you can. I have been having quite a hard time finding data on the liquids (expansion rate/time) and (volume/temperature). I hope others have an interst in this, while its not even close to overunity its a step in the right direction... MORE EFFICIENCY!

No questions, suggestions, or criticizism?!?!?!

Is it just bad idea or is it just of no intrest to this group?

Hi
Your URL does not work and what kind of format is that *.swf-file.

bye

The url works just not the links, you either have to copy and paste or or right click and save. SWF is macromedia flash animation.

I'm having trouble finding out how they got these numbers. Does anyone here know how I could calculate this information for the chemicals I listed???

Chlorethan (Ethylchlorid), C2H5Cl

@Dingus


try it with propan.

fill 2.2 atm in!

will work

Well hopefully someone with the means to test this concept will give it a try in the mean time I'm focusing PMM technology. How did you determine that information?

Try it ! It work.
I have "repaired" (filled) my frigidaire with them !

That I can understand but this concept is not relying on a chemicals ability to be used as a refidgerant but a chemicals ability to vaporize at near room temperatures. The most important aspect of any fluid that can boil at room temperature is its volume curve in ratio to H^2O steam. This is why I'm curious to how you calculated 2.2atm's of a liquid that boils at -42c would work? (I know the boiling point of the fluid increases under pressure, but how did you calculate the proper bar density)
