Have Universities and Industries got it wrong?

Any 82% efficient hydro turbine produces 720 watts for each one litre flow per second at 9 bar pressure. 
Carbon Dioxide above +32*C is a Supercritical gas, meaning its acts as if it were liquid.
One litre of Carbon Dioxide heated from +50* to +100*C has 8,000 bar pressure.  This converts to 640Kw.
To heat one litre of water by 1*C in one second takes 0.076Kw.
To heat one litre of water from 0*C to 50*C takes 38Kw. To heat one litre of water from +50*C to +100*C takes 38Kw, a total of 76Kw.

Electric input 76Kw, electric output 640Kw.

Further to previous post, "Electric input 76Kw, electric output 640Kw."

76Kw max? is needed to hold the CO2 at +50*C raising the input total to 152Kw, leaving an output of 488Kw, which may be higher as the temperature base needs be held at +50*C not raised 0*C to +50*C every second.

Instead of burning  of fuel in gas turbines, it would be a better idea to heat  a inert gas and use it to run the turbine.  When gas in a closed container is heated as shown in your diagram  it developes tremendous pressure.

Is there any practical device based on that principle?

Original post show only Chart for Critical CO2 not Supercritical CO2 and had a pressure of 8,000 bar at +100*C, not pressure of 10,000 bar at +80*C.

DaS Turbine works on the fridge principal that high pressure refrigerant stripped of if its energy turns cold. This energy stripping being done by the turbine. Vacuum immediately after the turbine is cooling booster. DaS compressor with no solid seal yet is solid sealed is part of the turbine so only one moving part exists.

Working at lower temperature fields the DaS Turbine absorbs heat for function. For every 9 bar variant in hot and cold Refrigerant a return of 720 watts is obtained.
