I'm re-posting from a question someone had on another thread. might be a clearer on the concept.
"We are based in the US and while there are definitely mining applications, the idea is that the computational load across a larger distributed network essentially becomes the "fuel" to keep the components hot and transferring heat. There's also local computational demand, so theoretically, the device could control anything in your house with a CPU or GPU. Globally, the collective computational power could be tapped by you, or third parties for whatever it's needed for - advanced math, research, whatever. It's not an uncommon model actually. SETI uses a similar platform where they will use a portion of your home computer's power to run calcs - but it's extremely limiting. This prototype is VERY powerful computationally speaking. Essentially, when you plug it into a network of other "like minded" devices, you've got access to a super computer that just so happens to heat / coool your home, give you got water, and act as a smart meter for all of your other digital devices.
That's the idea anyway!"
