We had this on RMMB and it was a great thread. Post your questions here, and hopefully people who are knowledgeable will be able to answer. There was one thing from the old thread that really had my interest. Did anyone ever really come to a conclusion one way or the other as to whether or not roads with built in solar panels were feasible, based on that link someone had posted? Chater Edit: This is a great thread and since most of us have gone to school, I'm going to ask you guys to brush up on some of the skills you learned there, primarily citation. If you're making an argument, provide links to legitimate sources to back your point. Arguing without citation and supporting your points is moot. Conventional wisdom is often the most inaccurate.
