 I'r hatteilwyr, you've got to recognise as a huge mental risk with us associate... who've taken in new technologies. But there's also real demand from utilities to see new technologies come through. And what I like most about this conference over all the who are the ones... is that real mixture of both really really good academics here, some of the best academics in the world, but talking to people involved in utilities and actually people whose job it is to develop technologies... and make them fit and ready for the world. The leading edge technologies attract people from a business-side perspective, they are looking into selling products, into commercialising, into implementing technologies to developers as well, so they are looking into where are the next opportunities to researchers to spread the word about some of the good work they are doing, and I think it's that really good blend that allows for the leading edge to be such a big brand and known worldwide. So it's the ideal place to pick up the overall overview of the field. It's helping me know what I didn't know before, and so the more unknowns I know, the better armed we'll be to solve our problems in the future.
