CPST is still part of the solution
A big part IMO because of the fuel flexibility, low-maintenance, etc. for listing all its advantages.
The one missing ingredient is economies of scale that keeps the price too high for mass adoption by retail/residential customers directly.
That might be handled by neighborhood micro-grids if civil authorities (our builders) had the foresight and guts to educate their electorate, fight the big utilities (we have a couple communities in N.C. that did that to the cable cos., establishing much faster and cheaper community-wide internet availability) and roll out the first few demo installations.
Ah well. Such are dreams made of.
