Allow players to construct a steam engine significantly more powerful than the vanilla version. Its ability to recycle water would compensate for the lack of high-stress power sources in the Nether (and encourage players to start experimenting with building large-scale turbine systems). However, this enhanced steam engine would be much larger, far less efficient than a turbine, though slightly better than the vanilla engine, and its steam throughput would be drastically lower compared to a turbine.
