Those high efficiency gas turbine power plants have huge heat recovery systems that could not possibly fit into an airplane.
So a 500 hp engine uses more fuel then a 350hp engine. I don't think people 20 years ago thought you would be holding a battery powered supercomputer in you hand either, and it makes sense Orville and Wilbur's design might be more refined then Adolf's, especially when the technology is used widespread from lawn movers to supertankers. I still say give turbines a little more chance before writing them off.
