On the Ottawa Citizen's website, David Reevely touches on a topic, that is, running a city like a business, that came up early in the thesis that Kate Murray, Chidi Ogbuagu and I did last year (here's the version of the resource guide with working hyperlinks). We were trying to create a business case for sustainability for cities. Cities aren't businesses, and the motivations that drive cities are different - they need to build more than just economic capital. That's why we instead did a report on how building community capital (including economic, built, natural, social, cultural, human and political) to move towards sustainability.
The comments on this posting are also pretty intelligent!

Thorium - will it give nuclear energy a future?
Just posted this on Facebook. Would like to hear the opinions of others.
Is there a place for nuclear energy in a sustainable energy system? What if its radioactive byproducts only needed 300 years of storage instead of tens of thousands years? And they couldn't be converted into nuclear weapons?
If we moved to thorium instead of uranium, maybe the threats posed by nuclear energy would be far smaller. I kept this in mind after Karl-Henrik Robèrt mentioned thorium in a session at Blekinge Tekniska Högskola last year. There may be a future for nuclear fission that is different from the past.
Your thoughts?
