I don't know really know this, not without some knowledge of calculus.
The average diameter of an ellipsoid should be the length of all the
possible lines crossing the center of the ellipsoid divided by the
number of the lines.

Here is determination using electrolysis and the electric charge
of an electron.
The Faraday constant is the electric charge of 1 mole of
electrons. It can be determined by using electrolysis. The amount of
metal deposited on an electrode is proportional to the electric
current times the time (which is electric charge). Faraday's constant
is the proportionality for a monovalent metal. The Faraday constant
was determined in 1834 to be experiment to be F=96485 C /mol. See the
links
http://en.wikipedia.org/wiki/Faraday%27s_law_of_electrolysis
http://en.wikipedia.org/wiki/Faraday_constant
The Millikan oil drop experiment in 1909 determined the
electric charge on a single experiment. The charge measured on a
single electron is q=1.5924(17)×10-19 C. See the link:
http://en.wikipedia.org/wiki/Oil_drop_experiment
Avogrado's number N can be easily determined by the simple ratio
N=F/q
The answer is
N=6.022x10^23
I am sure there were other methods to determine an estimate of
Avogrados number before 1909. However, I think this method is one of
the simplest, conceptually.

I bet if you try real hard you could come up with the average
diameter of potatoes.

yeah, but what is the integral value?

do you know the surfer's value of pi?

thus:
well, that is where the problem with assigning a particle
to a wave, a la de Broglie et al, comes. the assumption,
that causes folks to say "particle," is that because a quantum
(wave) of light is absorbed by one atom of siver dioxide (say,
in the photographic emulsion; or, other detector) --some how--
that it must be that a rock of light hit the electronic orbital
(although
this is never specified, as to how it could be, and the whole problem
of EM is also hard to describe, and variously is).

this is really all of a confusion from Newton's "geometrical optics,"
that is, the "ray" of light, which is just one "normal"
to the wave (or Huyghens wavelet).

thus:
about your five "cloture" events, the real problem is that
"the Fed" was never properly ratified (and is unconstitutional
for that reason, if not directly; it is modeled upon the Federal
Reserve System
of England). of coursel the 527 cmtes. have essentially taken
over the TV advertizing on all national issues & candidates,
through an Act that was passed unaanimously in both houses.

thus:
I've been saying, for a while, that if "green" gasoline can
be made, and gasoline fuel cells, what is the problem
with Fossilized Fuels (TM), which ain't fossilized? ... anyway,
see "Green Freedom" in the article,
which is not quite what I was refering to!

thus:
Copenhagen's "reifiying" of the mere probabilities
of detection, is the biggest problem, whence comes
both "perfect vacuum" and "quantum foam" etc. ad vomitorium,
as well as the brain-dead "photon" of massless and
momentumless and pointy rocks o'light, perfectly aimed
at the recieving cone in your eye, like a small pizza pie.

thus:
all vacuums are good, if they suck hard enough, but
there is no absolute vacuum, either on theoretical or
Copenhagenskooler fuzzy math grounds.

thus:
magnetohydrodynamics is probably the way to go, yes;
not "perfect vacuum or bearings" -- and,
where did the link about YORP, include any thing
about the air-pressure?... seems to me,
it's assuming Pascal's old, perfected Plenum.
twist your mind away from the "illustrated
in _Conceptual Physics/for Dummies_" nothingness
of the massless & momentumless & pointy "photon"
of the Nobel-winning "effect" in an electronic device -- yeah,
CCDs -- the Committee's lame attempt to "save the dysappearance"
of Newton's corpuscle.
also, please don't brag about free God-am energy,
til you can demonstrate it in a perpetuum mobile!
> It stops because it has bad bearings. These asteroids

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!
> Could neutrino availability affect decay rates?

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).

A whirling cylinder has a spherical envelope.
