| # One of the premises of the free software movement is that: proof of concept, running code, and presence of community are all that are necessary for success. A wiki cataloging a critical mass of models, spreadsheets, simulations, and documentation, in open formats, will attract people to help find and solve problems.

| # [[SpaceElevatorSoftware|No toys.]] Anything can be modeled in software so we will increasingly aim to simulate the real thing.
| |
| # Crawl, walk, run. We have big goals which is fine, and we will get there one step at a time. Any progress is good, however, we are too small to do waste, which is the "No toys" mantra above, and why we should reuse as much as possible -- standing on the shoulders of giants. The best way to make a wiki is not to start writing, but to gather existing things that belong in it!

| == CAD models ==
| |
| We need 3-D models in free formats usable by apps like this:
| |
| http://sketchup.google.com/
| |
|
| |
| (I suspect there is a free app to make models in that is better than sketchup, but with free formats, we don't care.)
| |
|
| |
| We could build all the basic parts as a 3-D model, then get people improving on all of them in parallel. What really does a climber need to look like?
| |
|
| |
| Here is a list of people who will build models for sketchup. http://sketchup.google.com/3dwarehouse/cldetails?mid=c9bd5e6d5b511d0e6c58fbbbefee0599

| A few space elevator models:

| This task is initially an archaeological expedition. Brad finds 3-D models he knows about and puts them up here. (I will go through the sketchup warehouse and create links to any that are cool.)

| Imagine you built a simulator so that when you added weight to the climber, the ribbon dimensions got bigger. If a spreadsheet created calculations that boiled down to simple algebraic formulas, those could be put into a video game.If someone improves the spreadsheet, they can swap in a different algebraic constant.

| There is also Finite Element Analysis software:
