“Other Cleantech News” Page

September 7th, 2011 | by Zachary Shahan

This is just a reminder that I've started a page here on CleanTechnica for sharing other notable cleantech stories from around. You won't see this in the article stream on the front page or in your RSS/Twitter/Facebook feed if that's how you follow us. You have to go directly to: Cleantech News (http://cleantechnica.com/cleantech-news-daily/), also linked in the left sidebar of all CleanTechnica pages. I update the page almost daily. This is my roundup from the past day or so (it's been an exceptionally busy day after the long weekend)
