Prelude has been mentioned in a peak oil-related commentary on The Huffington Post by writer Kelpie Wilson. I met Kelpie at a conference a couple years ago. She's currently the communications editor at the International Biochar Initiative. In that regard I recently wrote a piece reviewing Albert Bates' The Biochar Solution. Albert is active in the IBI as you might expect. The Huffington Post mention offers by far the most visibility for Prelude to date.
