CareX First Appearance For Net-Zero Scavengers

There is nothing new in terms of technology actually, because Robert Stirling had introduced this machine in the mid-19th century. Then NASA used it for its spacecraft several decades before releasing it to the public five years ago.

What’s new is its application in the Net-Zero industry which will be the next big thing in the next few decades. The engine which is generally called the Stirling Engine, or the one I hold which is similar in design to NASA — called the Free Piston Stirling Engine (FPSE), is one of the solutions to achieve the Net-Zero target.

In the CareX (Carbon Removal and Exchange) system, we function the FPSE as a cryocooler, which is a cooler that can reach temperatures of -150 C.

When brought closer to the source of CO2 emission it will immediately freeze the CO2 because it has a freezing point of only -78 C. While oxygen and nitrogen remain free to become clean air (not frozen) because their freezing points are -218.8 C and -210 C respectively, much lower than our cryocooler temperature of -150 C.

All the science and technology are complete, and we have even made the prototype. But we open up opportunities for engineers who love to work on machines — to disassemble these machines and improve the design.

In the Net-Zero era later, CO2 is like our everyday waste. Each party must be able to handle its own waste, or pay dearly to other parties who are able and willing to do so.

Just like garbage collectors who rely on their carts to collect valuable waste, in the Net-Zero era we need this kind of tool to collect CO2, which is still very valuable if we use it for microalgae cultivation.
