Played around with it for a couple hours and it's not bad. It has two new water boilers, one the same size as the vanilla one, and a 3x3 monster that I think you only need one of for max heat. It adds a type of currency in the form of "diamonds" that you can make with coal, or sell things for. You can refine raw ores for more output. Some badass looking caps and solar panels. It also has a 2x3 steam turbine that puts out 2.8 MW using two of those giant boilers, they are amazing when they are running of processed carbon coal.
