Makes a lot of sense as described, basically recycling using turbines retired for flight, but I wonder how efficient these retrofitted gas turbine generators are compared to turbines originally designed and built for this fuel and application. Edit: Turns out GE makes these things called LM2500 gas turbines and they're pretty much the same thing, CF6 aero turbines set up for power generation. They're advertised as being 35-39% efficient, which makes them rather on the less efficient end of the gas turbine spectrum. But they're light and quick to start so they have seem a lot of use in ships and some peaker plants. They definitely aren't the best turbine to be running a data center with long term, but if they can make them cheap and available that might be good enough. Not a new idea though.
