They are putting in mostly solar (CAT) turbines now, turbine engine, turbine compressor. The turbines require less maintenance, are smaller and are easier to manage emissions. The new turbines are physically a lot smaller than the GE series from the 70s and 80s. The downside to the turbines is that they do not handle small loads well without going into surge, so you end up recirculating a lot of gas just to keep them running in that state.

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
