One of that article's points was that nuclear plants only succeeded as mega projects, because:
1) they dovetailed with weapons programs so had a huge additional funding pool,
2) big projects add thermal efficiencies that bring the cost per kwh down significantly
3) any project needs near military grade security, which doesn't doesn't suit small sites
sample excerpt:
To be clear, if SMRs made sense, existing nuclear power generation facilities are the place to build them. They are already at the centre of the seven overlapping layers of defence that nuclear generation sites require from the international, all supply and waste chains and the physical and electronic security of the facility itself.
I've found this to be correct on most every e-bike I have rented. You can "feather pedal", just spinning the cranks without engaging any energy, and the e-bike will send power to "assist".
