The DaS Valve in effect is a possitive action pump with close to no wear parts. All mechanics is fully fluid arrived. The system may use any liquid that can be heated to a gas. The system requires 9 bar pressure for full operation. System output of 720 watts for each litre flow per second. Output increases by pressure or flow. Recycling Co2 is ideal as it has sufficient pressure at minus 10^ Celisus and builds upon extra heat. Water is just as easily used however its 720 watt output at plus 100* Celsius, is less than the 720 Kilowatts using Co2 at plus 100* Celsius.
