The mod doesn't seem to work with Steam Turbines, Nuclear Reactors and Heat Exchangers.
Also, with the Factorissimo2 mod, it shows 0% on every in/output of the buildings, which is really odd.

I think steam turbines, nuclear reactors and heat exchangers work differently than other factories. Do you know how to calculate the utilization of these? I can add support for those if i have a formula, but in my experience the performance of nuclear reactors and the other nuclear objects are very predictable.

I don't know where the 0%'s coming from in Factorissimo2 input/outputs, need to investigate that. Thanks for reporting it.

Released 0.2.2 which does not show the 0%'s on the Factorissimo2 factories. They use mining drills to show the arrows. Let me know if you find other issues.
