> Ask HN: How to reuse waste heat and water from AI datacenters?
- Steam Turbine
- Thermoelectrics (solid state)
- Gravel Battery, Sand Battery (solid state)
- OTEC: Ocean Thermal Energy Conversion (needs a 20C gradient)
- Water Sterilization
- Heat Pipe contract
- Commercial and Residential HVAC Heat
- Air Filter Production (CO2, Graphene, Heat)
- Water Filter Production (CO2, Graphene, Heat)
- Onsite manufacturing with Carbon & Heat (See: Datacenter Inputs)
- Carbon-based Chip Production (2D Graphene and other forms of Carbon)
- Thermoforming products (e.g. out of now easily-captured CO2 to Graphene and other forms of Carbon)
- Geopolymer production: pads to mount racks on, bricks, radially-curved outwall blocks
- Open-Source CFD: Computational Fluid Dynamics; use the waste heat to pay for CFD HPC time to reduce the waste heat with better materials, better facility design with passive thermofluidics and energy reclamation
- Datacenter Inputs: [Earthmoving, Infrastructure], Water, Air, Concrete, Beams, Electricity, Turbines, Bolts, Racks, Fans, PCs, Copper power Wires and data Cabling, Bandwidth, Fiber Cabling
FWIU most datacenters waste the sterilized water as steam, which has some evaporative cooling value?
In which markets is it already possible for datacenters [and other industrial production facilities] to sell or give sterilized water to the water supply utility?

> - Heat Pipe contract
E.g. Copenhagen Atomics wants to sell a heat pipe contract promise and manage the (Thorium+ waste burner) heat production.
It takes extra heat to pump heat through a tube underground to a building next door,
but it is worth it.
> - Commercial and Residential HVAC Heat
The OTEC Wikipedia article mentions Ammonia as a Working fluid (a thermofluid), but Ammonia.
Sustainable thermofluids for heat pumps would be a good use for materials design AI.

Biocomposites and Titanium are strong enough for beams and fan blades; though on corrosion due to water, titanium probably wins. "Cheap yet ultrapure titanium metal might enable widespread use in industry" (2024) https://news.ycombinator.com/item?id=40768549
Is there a carbon-based copper alternative for cabling that's flexible enough to work at CAT-5/6/7/8 ethernet cable; 40GBase-T at 2000 Mhz?
There appear to be electron vortices and superconductivity in carbon at room temperature.
Can we replace copper with carbon in cables and computers?
