.The most promising approach involves integrating ASIC heat with low-temperature Multi-Effect Distillation (MED) systems. These systems use the captured heat to evaporate seawater in the first effect, with subsequent effects operating at progressively lower pressures and temperatures. The vapour from each effect condenses to provide heat for the next stage, creating a highly efficient cascade process.
Good to see some information on this idea. Scaling desalination with Bitcoin has so much potential. We could easily grow a few hundred million bitcoiners in Australia with it.

It’d be interesting to know if heating water is cheaper right now than running a Bitcoin mining operation. I think that’s the real deciding factor.

It's cheaper to purify sewage than to purify seawater, so desalination is really only relevant in places without plumbing infrastructure... and even there it's the wrong approach.

Interesting... What makes sewerage cheaper to purify? Is it because its already liquid and contained?
reply
The composition of sewage is more predictable and a lot of the contaminants are organic, so bacteria can do a lot of the cleaning for us. If you go to a treatment plant, you can see that most of the process is just letting the water sit in big aerated tanks while the bacteria eat the poop.
The seawater has been sloshing around for millions of years and is full of minerals and things bacteria don't eat so you need to either distill it or pump it through a lot of filters.

wow, this is another level. Very good article !
