Either do not supply water or feed it oxygen.How do I do this? I can't place a heater because the bottom slot is the power input, the friction heater says it's a non-heatable machine and simply giving it more power or varying the torque/speed ratio does not appear to do anything. I've tried maximum torque at lowest possible speed and maximum speed at 1 Nm, for a total power between 2 and 8 MW. I get 873C all the time.
