Ah I see you googled "efficiency of a gas power plant" and ran with the first result. Excellent! The efficiencies of gas power plants are not measured in the same way as water heaters and the two numbers are not comparable. It is also not because turbines generate more power. They do, but most vessel's speed is limited by physics, not the amount of oomph they can put into the screws. Think of it this way: if gas turbines were less efficient that boilers, why has every navy on the entire planet moved away from boilers? It ain't because maintenance is easier or costs are lower with turbines, that's for sure. Gas turbines compress the gas. They are much more efficient than dribbling gas out of an orifice at 1 ATM and getting a nice blue flame out of it. Also, good job ignoring the fact that you were wrong about water heater efficiency and then dismissing my correction and then immediately changing the thrust of your argument. It warms my heart to see that people never change. Finally, your information about heat pumps is extremely outdated, from the 80s or 90s, I'm assuming you're older and don't keep up with technological developments? (or are an oil and gas lobbyist)
