  • The issue is that none of those have the energy density of nuclear power. A single mid-sized nuclear plant can power a small city, where that same city would need at least a half-dozen solar farms around the area (assuming there’s enough cleared land to support it - rooftop solar can offset, but it generally will not replace mains power), or tons of wind turbines (again, subject to area - not every place is a good candidate). Geothermal and hydroelectric are subject to that same issue - you can’t place them anywhere, there are very specific requirements to get one up and running.

    I agree we should work towards 100% green energy, but nuclear is an effective option dollar-for-dollar and acre-for-acre until we figure out a good way to increase energy density of wind or solar to a point where we don’t need enormous tracts of land dedicated to them in order to support places where people live.

    Mhm, society persists even through collapse scenarios mostly for exactly this reason. John the Butcher in 13th century Scotland might have lost his entire village to The Plague, but those guys in the village 3 miles down the road still have people who know how to forage, or hunt, or grow food, etc etc etc.

    Pretty much this. The average gets dragged down by a HIGH infant mortality rate - nest predators from snakes to raccoons to hawks and vultures kill a lot of hatchlings, as well as things like simple accidents (falling out of a tree, for instance).



  • Pretty much this. Elon was never interested in what he SHOULD HAVE BEEN: making an inexpensive electric vehicle that’s widely available. Tesla had the tech to do so, but they were being driven to make insane decisions like moving the gearshift to a touchscreen (gee, I love taking my eyes off the road to shift gears), or making “futuristic” doors that actually cannot physically open from the inside (whoops, guess those just can’t be recalled since DOT has literally no teeth).
