Re: Terraforming Venus will be easier

Besides our badly terraforming Venus, how about first doing something,
anything with our moon, then we go for Venus and proceed to screw that
planet up the way we've tinkered with Earth. This following actually
has a great deal to do with Venus, or that of our affordably
contacting whomever on Venus.


GUTH MOON DIRT EXPRESS (GMDE), and those Flywheels of Tether Energy

Regarding ESE From: Bob Munck
"For example, at 18,000 km -- half-way up -- gravity is down to .07 g.
If at that point you can switch from 200 kph rollers to 1000 kph
magnetics, you cut three days from the trip."

If the half way ESE point is 18,000 km, then 36,000 km is certainly
right smack in the middle of Dr. Van Allen's zone of death, of
receiving only 2^3 Sv/year behind 2 g/cm2 and, that's not actually
including any significant solar contributions per say, just the
typical environment + whatever.

Shielding requirements, such as those currently utilized for the likes
of ISS, for spending any amount of time at the ESE depot are going to
be limited to hours unless you're surrounded by several hundred g/cm2.
I for one would start off at a full meter worth of moon dirt (341
g/cm2), a longer stay (months) might require a habitat surrounded by
as much as 3 meters worth (1023 g/cm2). Per m3 we're at the mass of
3410 kg or 3.41 t/m3. Exactly how much cost and energy effectively
that sort of mass can be delivered via ESE is going to be doable, but
certainly not cheap nor without creating large amounts of CO2.

The energy to accommodate such terrific lifting is potentially
available via tether dipole and, of that energy being stored via
substantial flywheels. Being that the Van Allen zone of death most
likely holds all sorts of electro-magnetic energy potential, there
should not be any shortages of energy (too much if anything).

A 10x10x10 meter abode interior will subsequently require at least 728
m3, 728 * 3.41 = 2482.5 t, that is if you're going for a modest shield
surround density of equal or better than 341 g/m2.
