And yet you've decided you're going to continue to live in just such
a world.


Why, Brad?

The Moon is a Harsh Mistress - Robert Anson Heinlein


This is a good book.


All these plans are fantasy unless and until we build up our lift
capacity to match our needs. *We have about 2,000 tons of fissile
materials on Earth. *This is processed into 2 billion fissile triggers
1 gram each. *These triggers, using zeta-pinch techniques, create
micro-fission explosions which are used to detonate lithium-6
deuteride fusor elements, or boron fusor elements ina modified
miniature Teller -Ulam two-stage design. *These 2 billion pulse units
are used to power thousands of vehicles each capable of carrying
50,000 tons to 500,000 tons across the solar system in weeks.


A small fleet of a few hundred 50,000 ton ships - carrying millions of
pulse units - set out for the asteroid belt looking for rich
asteroids. *When found, the ships shepherd the asteroids or fragments
of the asteroids, back to Earth orbit, using a standoff propulsion
technique - which vaporizes a well defined section of asteroid in a
well defined direction producing a rocket like effect. *While each
pulse is small, thousands of them produce a highly controllable delta
vee - and in this way, asteroids are harvested and placed into a sun
synchronous polar orbit.


Very large solar power satellite arrays are placed in GEO using
nuclear pulse ships as well. *Power is beamed to Earth and to remotely
controlled factories lofted into orbit along with the rich asteroids.
The factories produce large pressure vessels whch are then populated
with crops and trees to create teleoperated farms and forests to join
the teleoperated factories on orbit. *Food, fiber, and every manner of
consumer good is deorbited directly to consumers anywhere on Earth in
minutes, following a satellite telephone call - in unlimited
quantity. *In regions where local government does not allow people to
enjoy this abuandance in peace, floating cities are deorbited, and
float overhead to collect anyone who wishes to leave.


Laser propelled spacecraft are ultimately deorbited and give everyone
the capacity to own their own personal space colony on orbit.


Or we could use that cache of fissile materials in order to greatly
improve the quality of life on Earth,



Umm... ridding the world of nuclear materials and nuclear weapons
improves life on Earth.

Using nuclear pulse engines built around old weapons materials to
orbit large solar power satellites that beam infrared laser energy to
users anywhere on demand, improves life on Earth, by lowering the cost
of energy, making energy more widely available and more abundant, and
ending the endless pollution of our air b ending the use of
conventional fuels.

Putting in place a large network of multi-point comsats to turn the
world into a global wireless hotspot, that supports billions of
biometric and VR signalling channels, does the same thing. Humanoid
robots like ASIMO work anywhere driven by workers who live anywhere -
this immediately improves life on Earth by providing meaningful and
profitable work for all.

Capturing rich asteroids, using nuclear pulse techniques to bring them
into Earth orbit, and using nuclear pulse lifters to place significant
remotely controlled factories on them to manufacture stuff and deliver
it anwhere its needed on Earth at extremely low cost - dramatically
improves life on Earth.

or at least within our Selene/
moon.


The moon is not particularly rich when compared to some asteroids,
riches on the moon are buried deep within the moon and must be
extracted, the moon sits at the bottom of a substantial gravity well
that without aerobraking adds significant cost to getting materials
out of the moon and back to Earth, the moon is more than 1 light
second away which means we cannot use present telerobotic techniques
as effectively as we can within 1/5th light second of Earth. The moon
will one day be a valuable resource, and one day be a vital inhabited
world, using the moon to resolve our materials issues on Earth quickly
is more problematical than asteroid capture and processing on orbit as
described above.

*Much like Earth, our Selene/moon even has a sufficient core of
geothermal energy.


No it does not.

Too bad we still do not have a viable fly-by-rocket lander for getting
ourselves safely to/from our Selene/moon


Your boneheaded contention that the Apollo flights did not occur as
described marks you as a profoundly troubled personality.

and its nifty L1.


Lagrange point 1 between Earth and Sol is more important. Lunar/Earth
L1 is a good place for a communications satellite - that's about it.

*I guess we
can only go so far on a given cesspool of mainstream lies.


The only cesspool of lies are yours sir. You love projecting your
reality to those outside you. Fortunately, no one is fooled - except
perhaps for you.

Since there's most of everything we need on or within our Selene/moon,
what exactly are we waiting for?


Please explain in detail how you would proceed and why it would be
less expensive speedier and more reliable than what I have described?

To recap;

1) sign an enhanced nonproliferation treaty and put all 2,000 tons
fissile material under international control - Ends the threat of
loose nukes
2) use weapons lobs to convert bombs and materials into micro-fission
pulse triggers - keeps the weaponeers busy
3) develop nuclear pulse engines around fusion elements triggered b
small micro-fission triggers - insipres universal cooperation, unites
world in a positive vision of the future.
4) build a fleet of 200 ships each 50,000 ton capacity as
interplanetary cruisers - provides substantial capacity at less cost
than US Navy.
5) put up a communications satellite network - provide global
wireless broadband - establishes mass produced space hardware achieves
early price point and productivity needed to advance, provides
seamless means to work remotely through telerobotics.
6) put up a power satellite network - provide global wireless power -
ends our pollution of the atmosphere, lowers energy costs, and ends
energy limits to growth
7) survey the small bodies of the solar system - select the richest
of these for retrieval - expands the availability of raw materials
while reducing the impact of human industry on Earth's biosphere.
8) retrieve the richest small bodies to sun synch polar orbit - ideal
location for orbiting factories, they pass over every point on Earth
twice a day.
9) place remotely operated factories on the captured asteroids -
using materials in captured asteroid, processed into useful goods that
are then delivered directly from orbit in minutes to anyone anywhere
in response to a satellite phone call.
10) expand orbital infrastructure - build products for use IN space -
large pressure vessels to house farms, forests and eventually people -
adding food and wood and wood products to the products available from
space.
11) build large pressure vessels that are capable of floating in
Earth's atmosphere - by heating the air within. These are similar to
Buckminster Fuller's Cloud Nine cities proposed in 1962. Tens of
thousands of these cities, each housing up to 100,000 people float
through the skies of Earth- supplied with food and water and fiber and
products from Orbit - communications available to all. People work
telerobotically anywhere on Earth or Earth orbit from these cities -
the cities float to any point on Earth and pick up anyone anywhere on
request - freeing the poor and powerless from tyranny. Large pressure
vessels are also built on orbit to house people who arrive there from
Earth.
12) homes powered and supplied and connected to space based
infrastructure are landed and self-erect anywhere desired. Many have
automated well stocked green houses providing minature farms - all
have teleoperated robots that allow people to recieve all manner of
personal services in their home telerobotically. All have a
teleoperation suite that allow homeowners to work anywhere and recieve
compensation to buy goods and services from the orbiting
infrastructure. MEMs based laser powered rocket arrays - forming
propulsive skins on the surface of personal spacecraft - make the home
spaceship possible - these too are delivered to people on demand -
anywhere - allowing them to travel anywere in minutes, or travel to
orbit and back at ease.

All these things improve the quality of life on Earth - and it starts
with converting nuclear weapons into nuclear triggers for nuclear
pulse rockets of tremendous capacity.
