New research: Combined Gas cycle

For late game, please add a new research item "Combined Gas Cycle" and add a new building, Gas Turbine, with 3d based on Steam Turbine with different color texture, and a new recipe for Gas boilers .
The new item, Gas Turbine, in input accept any gas derivative like actual gas boiler, in output mechanical power of 1MW (?) and hot waste gases
The new recipe for gas boiler: use hot gases for generating hi-steam and normal gas waste as the other gas recipes
So can increase the overall perfomance for converting gas to electric power like the modern combined cycle power plants

For a better explanation see the image of a generic combined cycle power plant:

This would be a great addition. Right now COI feels kind of like an RPG where you just have to grind to get to the next level. This would give players a genuine alternative to nuclear power, so you could choose which path to go in the late game. I already have an idea how to balance the gas turbine.
Gas turbine produces 18MW of mechanical power, like a super pressure steam turbine. It can burn diesel, light oil, naphta, ethanol, fuel gas and hydrogen. With fuel gas as an example, 120 fuel gas + 24 water --> 120 CO2 + 24 high pressure steam.
You could then build a set of level 1 high and low pressure steam turbines for 27MW of mechanical power, or build two gas turbines and a set of level 2 steam turbines for a total of 54MW of mechanical and 45MW of electrical power. This would be more compact and slightly more efficient than with gas boilers and steam turbines, much like in real life.
