Yes, that's what I thought. Many people seem to ignore gas turbine option, even if those are very reliable and efficient power sources. If there's interest towards different engine designs, it might be a good idea to check this out too: https://en.wikipedia.org/wiki/Wave_disk_engine https://en.wikipedia.org/wiki/Wave_disk_engine and another interesting design: https://en.wikipedia.org/wiki/Swing-piston_engine https://en.wikipedia.org/wiki/Swing-piston_engine There surely isn't shortage of engine designs, most of these designs are from 1800's. So nothing new.
