I hope we get away from centralized power generation because of the huge waste in delivering the electricity.
That depends on the fuel. All a stirling needs is a heat differential, and sunlight is pretty clean "burning" (at least from 93000000miles) as are geothermal and some others that can be used in home generation systems.
Solar power currently requires very large cells, but just as batteries are tiny compared to the original wet cells, I have a feeling solar cells will be downsized to the point of being practical for small transportation devices. Of course that is speculative, but I have yet to see new technology that didn't improve a lot over a short period of time. Calculators, computers and battery development are good examples of that.
My point was more that we have seen about as much improvement as we are going to in cleaning up fossil fuel power generaation (including running cars).
