Carbon Dioxide-CO2 is a natural refrigerant which turns cold if moving a higher to a lower pressure. This being the same for all refrigerants.

This process occurs when a block of Dry-Ice is put into the DaS turbine boiler.
The Dry-Ice at -40*C flashes of into gas and rises to 10,000 bar pressure at +100*C. Pressures of that force require construction using Stainless Steel.  Lesser pressures need lesser less grade material.  The working pressure is that found between cold point and hot point. The process works by having fluid block the CO2 gas from getting to the expansion chamber. This causes the CO2 to built up enough pressure to force the fluid out of the way. The fluid pushed out of the way drives a hydro turbine. When the CO2 has pushed enough water out of the way it trips an escape valve allowing the CO2 to travel to the expansion chamber. In this happening the cold gas held in the expansion chamber exchanges place with the CO2 in the boiler. During this process the fluid is draining back to again block the CO2 movement. Once started it will never stop due to the fridge physics of always returning colder gas to the boiler no matter what the boiler heat may be.
Construction including the turbine requires pipe, one way valves and a floating ball.

Interesting concept indeed, had a thought like this before. Found a clock that is driven by a chemical vacuum sealed system on wikipedia awhile back. But it would just react from simple temperature pressure changes from within the room it was in.

Have a look at this material:

Similar concept?

Hello Developing The Future,

Thank you.  I have seen the perpetual wound clock.

The irony I guess is it uses change in room temperature to create a vacuum and we use change in room temperature to create force.

Should you wish to built you need plumbing pipe and a squash ball.

For the turbine you can cut and weld pipe, buy a second car water pump, buy a turbine.

This all sounds so simple Peter.
How much work would it be for you to come up with a really basic sketch showing how it could be put together, with all the necessary valves/pipes/flanges etc there are for example filling CO2, putting the turbine together etc etc?
Prefeably also with dimensions so we know what sizes/volumes/flows/displacement we're talking here.
Thanks.

Hello Lynx,

Yes, it all so simple.

The attached is again the attached first posted as that is blueprint.

Follow the picture no matter what size is made.

The turbine is made from two lengths of pipe,  one twice the diameter.

Plastic or metal construct varies with pressure.

Volume replaces pressure in power production.

When making it leave it so the heater can be accessed.

Fill the water compartment first.

Put Dry-Ice into the heater and seal.

Dry-Ice flashes of at -40*C.   Absorption fridge Refrigerant is heated to pressure. Refrigerant always cools to lower heat than original.  It remain working to -30*C.

Care needs taking with the heating as pressure of 14.2 PSI at -40*C becomes 142,000 PSI at +100*C.

Hello Lynx,

Making the turbine,

Ok, thanks Peter, much appreciated
