To push waste heat to a building across the street, it's usually necessary to add heat at the source n order to more efficiently transfer the thermal energy to the receiver. OTOH other synergies that require planning and/or zoning: - Algae plants can capture waste CO2. - Datacenters produce steam-sterilized water that's usually tragically not fed back into water treatment. - Smokestacks produce CO2, Nitrogen, and other flue gases that are reusable by facilities like Copenhill and probably for production of graphene or similar smokestack air filters.
