I've been playing with this mod since it was released a couple weeks ago and I absolutely love how it makes tank combat viable at high evolution factors without making the tank completely untouchable. That being said I have a couple things I feel could be improved.

The fuel cells seem to last an extremely long time. It may be worthwhile to reduce the efficiency of the turbine or even the tank itself. Reducing the efficiency to 1/5 or 1/10 may not be unreasonable.

Calling find_entities_filtered appears to become rather computationally expensive in large factories. The on_tick function should probably operate on a cached list of vehicles to prevent noticeable slowdowns.
