In the last week I have become involved with Energy Cafe.
This is an experimental project running until March in Gunpowder Park, Waltham Abbey.
Their aim is to set up a cafe/meeting area which is built entirely from recycled or donated materials and runs on renewables.
On Saturday we established the site and got the wood burning stove up and cooking. Yesterday, we built a "field kitchen" from old scaffolding poles, tarpaulins, pallets for decking etc.
Today, although I was not present, they have a bicycle pedal power generator running and have been refining their woodstove skills.
After March, they will be mobile, as the Cafe packs up into a horsebox, and hopefully touring the various green festivals. I've let them know about the GreenHorizon event and they seem quite keen.
