What readers are talking about on the blog this week

This week on Gristmill, the big debate is over ex-Schwarzenegger adviser Terry Tamminen’s support for hydrogen cars. He’s taking a lot of heat — so if any hydrogen supporters are lurking out there, now’s the time to speak up. In other bloggy news, staff writer David Roberts’ cathartic rant about mythical dirty hippies provoked some amens, nature writer Jenny Price prompted some oddly intense literature review, and Andrew Dessler went to Nashville to learn climate-slideshowin’ from Al Gore. Drop by and share your two cents. Maybe together we can generate a dollar.
