Bruce Hardy, a Manitoba-based entrepreneur, has sought to repurpose the heat produced by his Bitcoin mining rig to produce edible plants and fish that are suited to the temperatures generated by cryptocurrency mining equipment. Mr. Hardy owns and operates 30 mining rigs, which are housed in a 20,000-square-foot building situated in the Rural Municipality of St. Francois Xavier, Manitoba. The heat produced by the miners is then circulated throughout the building, and used to grow edible plants and fish.
Approximately 800 Arctic Char are raised in a large fish tank located on the first floor of the building. The water that the fish are raised becomes highly rich in nitrates – and thus comprises an excellent plant fertilizer. With the press of a button, Mr. Hardy is able to remotely pump the nitrate-rich water to feed the lettuce, basil, and sprouted barley fodder which is grown aquaponically on the floor above the fish. “It’s all connected, much like Earth,” Mr. Hardy told local news. Mr. Hardy is also the president of Myera Group – a company that seeks to develop innovative and sustainable systems for food production.
