UA, how much of the effectiveness of a thoery of "curved space" can
be attributed to assuming Pascal's absolute vacuum, "in" space?

thus:
isn't the "recoil of atoms,"
the change of orbitals of electrons?

thus:
to put it differently, Bucky thought that "behold,
the tetrahedron" was a proof of 4CT, but
it just shows the *neccesity* of (at least) four colors,
not the sufficiency thereof. (and, of course,
since the tetrahedron is self-dual,
you can color the vertices, instead. which is to say,
almost all treatments of 4CT use graphs, because
it is exactly equivalent.)

thus:
so, a lightmill is that thing with black & white vanes
on a spindle in a relative vacuum?
you can't rely on "rocks o'light" to impart momentum
to these vanes, only to be absorbed electromagnetically
by atoms in them; then, perhaps,
the "warm side" will have some aerodynamic/thermal effect
on the air in the bulb, compared to the cool one.
thus:
even if neutrinos don't exist,
Michelson and Morely didn't get no results!

thus:
every technique has problems. like,
you can't grow hemp-for haemorrhoids under a photovoltaic,
without a good lightbulb.
the real problem is that, if Santa Monica is any indication,
the solar-subsidy bandwagon is part of the cargo-cult
from Southwest Asia (as is the compact flourescent lightbub,
the LED lightbulb etc. ad vomitorium).
