IMHO "it does not solve the issue of intermittency at all" is a nirvana fallacy. Reducing the effects of intermittency on production by bumping up the throughput of interconnections (in order to aggregate production on a vast geog

Each and every parameter (even "population size") has an interval of 'adequate' values. Too few of anything, or too much of it, leads to major downsides.

Too much or too few of anything isn't (by definition) adequate. By craving for material comfort we want: to possess more => better yield => economies of scale. This leads us to live in conditions which aren't appropriate to
