Speaking only about U233, produced in the thorium fuel cycle: it's been used in composite fission cores in several tests by USA and (then-) USSR. There may have been one small test of an unmixed U233 device by India. [1] So maybe U233

I would say "better adapted to an urban environment than a rural environment". That distinction may be different from smarter or more intelligent. I think it's complicated.

I agree with all but your last point. Facebook leadership's lust for power doesn't make politicians blush. It turns them green with envy.

Good idea. There may be enough impact and vulcanism events with reasonably good dating to search for the former as a cause of the latter.

One answer is to accept that unions, like other human organizations, will always have power-structure problems but that on balance, we do better when workers have actual bargaining power. Most of the problems with unions could be mitigated

Maybe. On Mercury, it seems the impact that created the Caloris basin [1] may also have created a seriously busted-up region at its antipode (opposite on the planet from the impact) [2]. This may have happened due to shock waves propagating

I flew when I could exit a departure lounge and walk up mobile stairs to enter the aircraft with no screening whatsoever. Like, none. Yeah, it feels really different.

Understood. I took the OP's "how much water flows past generators" to address whether all the dam's outflow goes through the turbines or whether some is diverted around them. The former is the case. The latter only happe

At Hoover Dam, 100% of the river flows through the turbines with no bypass. The dam was originally built for flood control. Power generation is driven by downstream water demands. [1] [1] https://en.wikipedia.org/wiki/H

RoI may go beyond financial measures for some of us. I'd invest even if the only yield is longer/better life rather than $. More $ - not terribly important beyond a threshold. Longer/better life - yeah, that's important
