TODO; though/also - after a gas turbine or solid-state TPV cell array - you have to store electricity, which is lossy and inefficient:
An electric motor's efficiency is not necessarily the same as its generator efficiency in reverse.

> Electrical conversion efficiency: Of all of these technologies the solar dish/Stirling engine has the highest energy efficiency. A single solar dish-Stirling engine installed at Sandia National Laboratories National Solar Thermal Test Facility (NSTTF) produces as much as 25 kW of electricity, with a conversion efficiency of 31.25%.
