Tom - Great! Perhaps we should all grow gills? The energy required per person is likley to asound most.
One reason why I don't hardly trust any proposals other than O'Neill's: large gossamer-thin Mylar mirrors reflecting natural sunlight into agricultural areas. Zubrin has commented on the power requirements to reproduce Earthlike levels of sunlight via artificial means, and they are rather astounding.

Mylar is likely to have a lifetime of around 5 years due to atomic oxygen from the solar wind. So, routine replacements will have to be planned if his approach is used. Glass and auminum are more durable materials.

Mike Combs
