Hi everyone,
We’ve been experimenting with a setup that reuses
heat from mining rigs — both GPUs and ASICs — to drive a
membrane distillation process for desalination.
Key idea:Mining hardware produces a lot of low-grade heat (around 45–60 °C).
That heat can be redirected into a compact thermal desalination module.
With a 25 kW heat source, the system can generate up to
10 m³/day of clean water, depending on local humidity and feed salinity.
What we’re doing now:We’ve already built and tested lab-scale and 25 kW pilot units.
https://www.solarprint.tech/mining-desalinationAt this stage we’re mainly running
thermal efficiency calculations — looking at how output changes under different conditions (ambient temperature, salinity, water vapor pressure).
We’re open to sharing these calculations with anyone interested in collaborating or exploring waste-heat reuse.
Why this matters:For regions with cheap power but limited water — mining could actually support local sustainability rather than just consume energy.
Turning ASIC heat into water changes the narrative:
heat can become a resource, not waste.If you’re running immersion or liquid-cooled miners, we’d love to hear your thoughts:
– What’s your typical coolant temperature range?
– Have you tried using waste heat beyond space heating?
– Would data on real heat–water conversion efficiency be useful for your setup?
For now, we’re not sharing full schematics — but we can discuss performance models and the physics behind it.

Mining can be sustainable. When its heat creates water, not waste.” 💧
