 I've been involved, as has Ron obviously, but in this programme from the start over the last five years, it's been a significant part of my life in NERC, but this day really served as a reminder to me of just how much has been undertaken within this programme since it was launched and again how many people have been involved in the delivery of all of those various funded activities. So for the majority of today we've been talking about the demonstrators, but there are also a large cast of actors associated with the feasibility studies, two waves of feasibility studies that were carried out and obviously with the mini demonstrators as well. So, you know, we may just happen to be sort of front of house talking about this stuff, but we're part of a much larger cast and community that have been delivering and building what will be a significant legacy, I think, and that's already embedded within a lot of NERC ways of working that will be carried, will be carried forward. So, again, making these sort of events happen take an awful lot of work. I've been acutely conscious of the fact that I handed a difficult task to the champions and their colleagues at Cranfield in the sense we had a very big event at the British Antarctic Survey only a matter of a month or two ago. And with August in the middle we had to do it all over again but with a much more applied focus at the Royal Society in early September. So that's taken a huge amount of effort and there are people here like Critty and John who have, if you could both stand up just so people know who you are, who have really worked day and night to make this happen. So the last thing I'd like to say, and Steve, I think it's your turn to say something next, is we're having a small reception immediately after this, which will involve champagne, I've been told. So if people would like to remain and mingle then please do so.
