I was the first invited speaker, and had intended to travel in person. Circumstances stopped that; it's a shame I couldn't interact more with the people at the meeting, including Prof Kevin Anderson, but at least I didn't have to spend days on a plane, and my carbon generation is a bit less. Instead, I recorded my slides a few day ago. My slides (with recorded voice) are now posted on slideshare; maybe also on You-Tube if I can figure it out. Note, that to hear the voice you need to download the file, which is almost 80 megabytes.
Susan and I first met during Diwali in Delhi, in 1985. On the next night I left Delhi to travel by train for three days to West Bengal. I still vividly recall my emotion as I passed through what seemed miles lit by thousands of candles, with no electric light anywhere.
