High efficiency drives

Bill,

I see. Your scenario is way out there in the future, and I am looking a the near future to see how we can build the 1st colony.

Since the earth's population only increases at 80 million/year, why move 1/2 million per day? Why not 1/4 million or 1 million while we are on the topic?

How much of the infra-structure would be build in space and how much supplied from earth? What is your presumed launch cost per KG? Presumably this would be low enough for the average person to afford, say around $1/KG?

What is funny is I have no way of complying with your request at the
moment. I have no windows machines at my house, and the zip program on
unix doesn't produce a file that pkzip can uncompress.

I'll get it into a zipfile and post it.

To give you an idea of what I was trying to accomplish, imagine what
infrastructure you will need to move half a million people into space
a day.

This included things like ground transportation/storage large scale
launch facilities, construction requirements for housing, factories,
ships, power equipment.

With half a million people to huase in space every day, you have to
build a Oneil cylinder every day.
