Hmmm . . . It does not say. I assume it is a conventional turbine, driven by kerosene. Aeroderivative turbine generators are the most efficient in the electric power biz. They are combined cycle; the waste heat from the turbine is used to boil water which drives a steam turbine. This article from Boeing says that batteries are nowhere near good enough for this airplane, but improvements are expected: http://www.boeing.com/Features/2010/06/corp_envision_06_14_10.html - Jed
