I like that thought. Assuming the heat exchange plumbing and attendant sensors could be made efficient and reliable enough to be relied on, the ability of panel designers to optimize their panels for operation in a tighter temperature band, should allow for improved efficiency of primary generation as well. Sounds like this mega plant is designed with a fair amount of redundant capacity; for cloudy days, maintenance etc. If so, this may facilitate "real world scale" testing of approaches like yours without unduly affecting "production."
