Time for a fresh open thread! (the old one being weighed down by over 1000 comments).
The Open Thread is a general discussion forum, where you can talk about whatever you like — there is nothing ‘off topic’ here — within reason. So get up on your soap box! The standard commenting rules of courtesy apply, and at the very least your chat should relate to the general content of this blog.
The sort of things that belong on this thread include general enquiries, soapbox philosophy, meandering trains of argument that move dynamically from one point of contention to another, and so on — as long as the comments adhere to the broad BNC themes of sustainable energy, climate change mitigation and policy, energy security, climate impacts, etc.
