Sure nanoprobe. The problem with AC is that you basically spend one kilowatt cooling energy for one kilowatt of crunching power. And the cost of the kWhr where I am is pretty high. So full power when external temps are under 8 degrees Celsius and very little when we reach 25 or more like these last days. Installing forced ventilation is the solution but in my small basement place it is not practical at all. The only solution is to move everything somewhere else. But where? That is the 10'000 $ question. I tried to negociate a solution with the Swiss Federal Institute of Technology that is 500 mt from where I live but they have also terrible problems of space and cooling issues. I should move everything in Finland over the arctic circle. I should have no problem the whole year there.
