The Prometheus Gas Turbine Project Introduces A New Electric Gas Turbine
Is this for real? Something fishy about this (okay, yes, diesels have a better SFC than gas turbines), since this doesn't seem to be a special case of a generic turbocharged diesel. There have been direct compound piston diesel gas turbine hybrids before (turbo-compound) in aviation, and a terrestrial version could easily include electric reheat of the diesel exhaust before turbine entry to emulate this concept. I suppose decoupling the diesel from the compressor/turbine (turbocharger) stack via electricity gets over the mass flow limits of the diesel. In some ways this is similar to the newer electric assist turbochargers, which can function in both motor and generator modes (generator mode limits turbo RPM to eliminate the need for a wastegate).

Interesting arguement that a SPS demonstrator can be built now with COTS/near COTS hardware, taking advantage of mass production of terrestrial products to reduce costs. The primary tricks being accepting losses in efficiency and overcoming it by reducing system mass, so the actual W/Kg is still higher. Thin film solar, carbon fiber booms, thin film inflatable reflectors and optics, power equipment mass reductions, and lower cost space access (SpaceX) are the COTS components that make at least the demonstrator possible. There is the interesting talk of making sure most technology/products are dual use, such as wireless power transmission to HALE LTA UAV sensor blimps to offload payload power requirements.
