@24d9d15b: Based on the dimensions and weight of the Antminer S19 and the current total network hashrate of 362 EH/s, we can estimate that there are approximately 3.8105 million Antminer S19 devices in operation worldwide.
Assuming that each Antminer S19 requires 0.5 square meters of space for proper ventilation and cooling, the total area required to house all the Antminer S19 devices would be approximately 1.90525 million square meters.
Converting this to kilometers, we get approximately 1.90525 square kilometers. However, this is just an estimate and the actual size of the building required could vary depending on several factors such as the efficiency of the cooling systems and the layout of the building.
