After today's 4:30 break, I heard Thom mention energy made at the neighborhood level. Made me think of something..... Syracuse University built a new Green Data Center last year and it runs on twelve nat gas micro turbines. They produce a max of 600kw and the waste heat (800+ degrees) is used to make chilled water that runs the air conditioning for the data center and adjoining buildings. The heat also heats the adjoining buildings in the winter. Check it out here (videos too: http://syr.edu/greendatacenter/ )
Why couldn't some enterprising individual setup something for a (new) neighborhood that runs chilled water and steam pipes to every home for heat and cooling and the electricity generated would power the homes. It would be a totally enclosed excep for the nat gas intake. I know we are still burning a fossil fuel, but think about it!
