In 2002 John Howards Office fostered DaS Energy development in Carbon storage. It was soon realised with the help of American NASA that CO2 is an excellent Refrigerant.

This proceeded in development of a fridge like design that replaced the Refrigerator restriction valve where the hot high pressure Refrigeration (absorption fridge)is stripped of its energy turning it into cold low pressure liquid.

In this method the energy is wasted as opposed to being converted to shaft power.

By replacement of the restriction valve with a turbine the same hot high pressure gas energy stripping occurs and the Refrigerant turns cold and liquid which like a Steam turbine is pumped back into the boiler.

To drive a 350 megawatt turbine a drive force of 200 bar is required, and if such is provided by Steam then it needs be +600*C.

This same force is obtained using CO2 at a temperature of +50*C.

CO2 if further heated to +100*C provides a force of 10,000 bar.

All of which is web published as Open Technology meaning any person can copy and use.

However there appear little point in doing so in Australia as the LNP has decided all Green Energy must be backed by coal burning such as Photovoltaics and Wind Power.

Set against Tarong Power QLD burning 240 tonne of coal per hour a massive Carbon reduction occurs but does by less coal burning and no need for water.

This is felt to be odd given a massive cost reduction in the production of electricity be of benefit to all.

Full blueprints are available at now cost.

The same design if having a three litre flow per second at +30*C will provide 10KW.

Hello All,

DaS Energy,

Not bright at computers, and now see bad spelling in last post, DaS Energy CO2 turbine should read at no cost, not now cost, it being Open Technology.

Thank You!

DaS, your post does not make sense. CO2 is never a low pressure liquid.
And a bar isn't a unit of force, it's a unit of pressure (10^5 Pascals, which is approximately atmospheric pressure)

Do you actually understand what you're saying?
If so, please rephrase it in a technically accurate way without the rhetoric!

Hello Aidan,

CO2 not above +33*C(70 Bar pressure)can be held as liquid, 1 bar being equal 1 atmosphere.

Above +33*C no amount of pressure shall turn CO2 liquid.

Pressure is a force!

Hello DaS,
"CO2 not above +33*C(70 Bar pressure)can be held as liquid,"
Correct, but that's not exactly low pressure, is it?

"Above +33*C no amount of pressure shall turn CO2 liquid. "
Correct, it's a supercritical fluid.

"Pressure is a force!"
No it's not "a force", it's force per unit area.

Are you able to rephrase your original posting in a technically accurate way? Because right now I can't even tell what you think CO2 turbines are capable of, let alone whether you are correct in that assessment.

Hello Aidan

I usually speak in layman's terms. Unit force is applied to stationary containment.

A 70 bar force is generally known as being low when compared to 10,000 bar.

We passed through thinking in 2002 when we first began modelling.

To obtain the turbine/generator output (82% efficient) 1 litre per second at 9 bar produces 720 watts.

This we developed to replace the 350 megawatt steam cycle turbine +100* to +600*C, by using absorption fridge physics, +30*C 70 bar to +10,000 bar +100*C, leaving a clear 9,000 bar at one litre per second (60RPM) 720KW.

For domestic purposes 3 litres per second (60RPM) -10*C 20 bar to +30*C 70 bar, 10KW.

Wattage output doubles by doubling volume or pressure per second.

After being given to the world in Open Technology at Copenhagen in 2010 the Chinese made the 10KW model(100,000 per year) operating at top heat of +20*C and uses a 1KW electric compressor boost.

Both Engineering forum and Refrigeration forum have the blue prints.

The last development before closing the company is a one piece mechanism which is turbine alone (Engineering forum picture the vertical shaft) whilst the horizontal shaft uses the same part but in different layout.

Quite happy to post on this site the entirety, however as yet not known how this be done.

Its development began after a Church ask to reduce the Carbon levels (in the sealed jar if you like) which is essential our home Planet Earth and it atmosphere.
