2. Contact everyone I know who is passionate about whatever it is they do, and inform them that they can live here, as long as they're productive and clean up after themselves, etc. Focus on people I know who are into green technology, and people that are just generally awesome.
3. Spend the rest of my life learning, implementing, and creating awesome stuff with other people doing the same. I personally would be making music, implementing an mmo where the npcs learned from their surroundings and the actions of past npcs, and were controllable by a human at the individual and group level, learning and working with electronics - making effects pedals and similar, and researching and implementing ways to use technology to improve the average humans existence without totally raping nature.
3.1 Try to set up more places like that.
EDIT: I wrote out a bit of an extrapolation on this idea, you can see it here: http://kaens.blogspot.com/2008/09/what-i-would-do-if-i-had-1... if you're interested.
