Photovoltaics actually shaves off peak quite nicely, and reduces 
the price of electricity. If you don't want to invest into MWh
storage (redox flow or otherwise) you could checkpoint a bit
before sunset, and resume when power is available. 


You mean.... supercomputing types coming out in the DAYLIGHT? Working normal hours?
That will never work. 


Joking aside, that is a good idea. Just have to manage user expectations when there is a cloudy day!
