“After the carbon dioxide passes through the turbine, it’s cooled and then repressurized before returning for another pass. “
I fail to see how this as a positive return on energy because more energy will always be required to pressurize it than will be extracted from it.
I believe they would use hydro power...................
He’s not selling this as an energy source but an energy transformer. Heat to rotational energy to electricity.
It requires energy to operate just like any other turbine. The only difference is that it is more compact.
