500 MW GE turbines claim 64% efficiency, and one can use the wasted heat for district heating. If we have to burn something then using these turbines seems to be the best option, running 2-3 electric cars for the emissions of one. And probably 3000 e-bikes. Shouldn't you compete in this range of efficiency?
There's only so much district heating that is needed. And mostly only in the winter. You'd actually need more energy for cooling in the summer when nobody wants to heat their place. District heating is a nice creative solution for waste heat. But there's a limit to how much of it you can use and how practical it is to use it. Mostly it's still waste heat that's going to be wasted (blasted straight into the atmosphere and space).
And we don't have to burn stuff. Which is why coal and gas powered electricity generation is a bit under pressure in most markets. There are cheaper and better ways to get energy now.
