Gosh .. living on a moon colony? What a boring place that would soon become. No Kentucky Fried Chicken, no Mc Donalds, no Burger King, no whiskey!! No thanks, I'll stay here with Brittney.--- CHAS
[quote author=JohnFornaro link=topic=15838.msg370225#msg370225 The kind of leadership required in the space community would acknowledge the need to plan for the political independence of our future colonies. This is not a hare brained utopian dream, it is the reality we need to face.
So, building a giant space frisbee to shield the Earth from the Sun while we burn the rest of our fossil fuels represents the business mindset at work?
This is not applicable to lunar colonies since they will not be able to survive without support from earth.
"If it's cheaper..."Big if.
"Non-Plausible, too many assumptions" I actually read what I write, and I was hoping to make only three assumptions, but I kept on going to see just what it would take. So I hear the plausibility argument. But the technical argument is still mine. We coulda done it if we wanted to.
The top quote about 1/3 SaturnV per person above came from the following thread:
That was off the top of my head to give an orders of magnitude idea of how much energy material it takes to put a person on the moon. Go look at a Saturn V, and think about launching 2 of those per day, for 40 years. Work how much of world jet fuel production you'd burn in the first stages.
2x365 = $730bln. We have just spent a great deal more than that bailing out a bunch of bad businessmen. Let's say it costs $270bln a year to build an maintain the 2-launch/day infratstructure. Thats a trillion dollars a year, which sounds enourmous, but is still only a fraction of the US budget.

Work how much of world jet fuel production you'd burn in the first stages.At two a day - not a noticeable fraction of world jet fuel production. If nothing else, consumption at such a rate would spur production.

It's a fraction of the US budget *now*(roughly 3%), but in 1970 it's roughly 130%
