    china already have a supercritical carbon dioxide system integrated into a functioning powergrid and operating commercially. The system exploits an exotic phase of co2 which expands to fill a volume like gas, but moves frictionlessly through tubes as a liquid. There are concerns about lifespan because of how caustic the system is, but apparently some new materials are being trialled which negate this.

      This is mainly integrated AFAIK in industrial processes with high amounts of low entropy heat available (i.e. big volumes of not-that-hot liquids), and it allows for electric production from said heat with unprecedented efficiency. Cool shit
