Carl, Sounds like you have been having a great weekend! The papercrete sounds like fun. I should very much like to meet up and discuss possible joint developments. I'm in Surrey - I believe your not too far away- Hampshire? Have you seen Alex English's Big Top design. Sounds like your onto a similar winner. We should get our wives together - they can freak out together - "Wood Gasification Widows Society" Drop me a line -we'll arrange a meet. Ken Redhill, Surrey.
