I've been to a few of these events, and every one is different.
http://r-urban-wick.net/events/open-workshops-775 covered the local maker movement workshops that were being founded all over different parts of London, and got a group of the founders together, where we had a lot of networking and sharing of idea's, as well as discussing what did and didn't work.
http://r-urban-wick.net/events/extra-ordinary-knowledge covered only some of the local initiatives that have been going on in East London.
http://r-urban-wick.net/events/local-waste-to-energy was part of the London Design Week events, and it covered some of the local projects that are aimed at sustainable production of energy.
http://r-urban-wick.net/events/micro-digestion covered the successful production of methane from local food waste. While it works relatively efficiently on a small scale, Hackney Council built this on a larger scale which gives greater efficiency of energy production, http://www.vitalenergi.co.uk/casestudies/shoreditch-heat-network/ The founder of the original project has gone on to work on projects in North Africa.
http://r-urban-wick.net/events/self-build covered the work being done by people who are choosing to self-build, rather than buy existing structures, and the ways that they were choosing more sustainable methods of doing so. There were also members of http://www.eastlondonclt.co.uk/ who were talking about the local initiatives that they've been using, to help stop people being priced out of the London housing markets.
Like i said, every event has been different, but they've all been interesting, practical and useful.
Whle these projects have a distinctly London-based focus, the original inspiration came from a project in Colombes in France, http://r-urban.net/
