I know that at 8km/s it takes 8.6 hours to get from earth surface to
GEO, which is only 41,000 km up. At 11km/s it should take around 6
hours. Given the goal is reaching the L1 point (at around 185,000 miles)
with excess velocity, I'm guestimating off the cuff around 50-60 hours
at a bare minimum to reach the moon with conventional propulsion.

Hey, I'm not saying its not possible. I just think that people are
giving earth governments too much credit. They are way too incompetent
for this to be probable.

To who? TO you maybe because you have a modicum of vision. The average

Destruction of facilities would be acceptable. Desctruction of civilians
would raise such a ruckus in the UN that it would likely break up. Japan
alone would walk out of the UN if the subject of nuclear bombardment
came up.

What do you mean, as far as I see, its lunocos fifth column. The
stockholders would be the most likely to push earth gov to acceed to
lunar independence, as they would probably control a large percentage of
the lobby and reelection money that politicians slather over.

True, but when in history has that ever really worked? All it would take
is one rogue nation willing to act as a landing field for lunoco
transports. Promise them the earthside He3 concession, and you'll have
two bit countries falling all over themselves to toe the lunar party
line.

Possible. I just think that given gov'ts past record of incompetence,
and the added weight of supporting whining retirees and welfarees that
contribute nothing productive, will doom any earthgov enterprise.

Yeah but the levels of flux that are run through such coils for use in
induction guns is extremely high, I would guess, until I dig up my
formulary for pulse power devices, that it is as high as that which
would be induced by an EMP from a near miss. Its the microelectronics
that can't stand EMPs. Thats why survivalists all drive cars with
point/coil ignition systems, so when doomdsay comes they will have cars
that still run.
