Re: for the close of all fission nuclear reactor in the world

Some answers:
If K-40 is the source of random genetic changes, how does one explain that
quite a few species, e.g., beetles, have existed for millions of years with
very few genetic changes?

K-40 affects every cell that uses Potassium, in proportion to its
concentration. The use of potassium varies immensly among life forms.
If the "creature" benefits by a change its genetic structure it will
change and produce a new variant, if not, the current version
continues to dominate. Beetles and flies are relatively simple, with
little redundancy that allows permanent improvement, which is why we
experiment on fruit flies; they change easily, but the changes are not
usually profitable to the gene line. Sure they change; and die and die
(but sometimes not, so there are several kinds of beetles now, but
still beetles). Some fish did quite well after a series of
developments; some even crawled onto dry land and took to climing
trees and eating bananas; sharks: well, there are bigger and smaller
sharks, but really they were already too specialized 'way back.

Then, you also believe this is the primary energy source for Earth's
geodynamo? What about lightning?

Sorry, but that is free for the taking. Lightning is just another
energy redistribution method in a conservative system.
Try pumping air up a vertical plastic tube about 1 Km long that has a
wire running to the top. Eventually you won't need to pump air since
warmish air will start entering by itself and exit at the top end;
water will descend the tube and free electricity from the wire will be
available for frying things. It all comes from cloud formation by sun
's heat on the oceans (we call it a heat pump with side effects).

Given "safe transport", what's the energy cost to haul this *** up out
of Earth's gravity well?

Actually about $32 per kilo. Not the way NASA does it, but by
electrical rail gun (not suitable for humans but fine for solid
materials). First get really high up a mountainous area (using same
electical method, but very small acceleration initailly); then use
high acceleration to escape velocity though very thin air.
On the moon this would be the easiest and cheapest method by far. The
two-step Earth-Moon-Sun method is better because you have to kill most
of the Earth's transverse (tangental velocity). I'ts easier to first
reach the Moon, then choose your direction and timing right; you can
get the Moon's velocity to cancel a lot of the the Earth's at parts of
the Moon's orbitt, so you can shoot pretty much "straight down" from
there.
