the math is simple, especially for the min-value current, hashrate of bitcoin net is ~30 Mio TH/s, S9 Ant Miner does 14 TH/s so you need at least 2.1 Mio Ant Miners with a power consumption of 1.3 kW so you get ~2.9 GW, and and to get an idea of the future blockchain.info/de/charts/ha…

True. Where did you get the 1.3kW figure from? It’s advertised with 0.98W/Gh, which would yield >13kW for 14TH?
