43KW for a House?! Dang!!!
I worked on a Go-Generation project, where two 60KW Generators with Gas-Turbine Prime Movers (using the Utility type Natural Gas), were used. This was within a 4 floor Commercial Office Building, and load calcs showed this 120KW would be ample for normal usage, plus some overhead to be sold off to the PoCo.
Just wanted to say a few things...

P.S.: The setup also used an evaporative chiller, which took the "wasted" heat energy and applied it to heating the Building's Water - in conjunction with a Storage type Water Heater.
Great idea on the reuse of as much energy possible!
