The only problem is it doesn't work

In the high desert of central Arizona, more than five thousand miles from the global-warming summit in Copenhagen, sits an aging and unfinished vision of the enviro-friendly, sustainable life that some climate change activists foresee for us all. It's called Arcosanti, created in 1970 by the Italian architect Paolo Soleri, and it is the prototype of a green community of the future.

The only problem is, it doesn't work. And it never did.

P.S. Don Surber, Via Steve Bartin:

The New York Times reported: “Gelbaum, an intensely private philanthropist who has long insisted on anonymity in exchange for his gifts, said in a statement that he had made more than $380 million in donations over the last four years to the A.C.L.U. and two other organizations, the Sierra Club and the Iraq-Afghanistan Deployment Impact Fund of the California Community Foundation.”

What did him in?

Obamanomics and global warming.

He invested heavily in alternative energy projects.
