Challenge: Can we heat food-growing environments by harvesting surplus heat generated by digital technology?
Project description: The Blockchain Dome Heat Station is a solution for providing low-cost heat all year round for greenhouses and other agricultural applications. Modern, high-powered computer servers (such as those used in blockchain operations) generate large amounts of heat that is normally wasted by venting it into the atmosphere.
Instead of treating this surplus heat as waste to be disposed of, the Blockchain Dome treats it as a valuable economic resource. Each server is located next to a vertical pipe connected to a series of underground cooling tubes using a ‘Canadian Well’ system, where air, drawn in from outside, is cooled by the surrounding earth. The air passing over the warm server rises to the top of the building where it is transferred to adjacent greenhouses via a tube located in the roof, cascading through a series of applications, starting with a tropical greenhouse and moving to more temperate environments, with any residual heat being used for agricultural drying.
Each dome has an electrical input of 1.5 to 2.25 megawatts, and produces 5-7.5 m British Thermal Units (BTU) of heat per hour, and 200,000-300,000 cubic feet of heated air per minute (CFM).
