Martin Rigley and Laura Porcu

This evening on an absolutely foul night I attended a Bright Sparks event in the quite wonderful Over Haddon Village Hall.
The hall has a very low carbon footprint and it was a fitting venue as the subject matter of the evening was sustainable energy, green things and the like.
I must confess to it being a bit over my head and the speakers seemed to be speaking in braille!!!
Here's Martin Rigley and Laura Porcu who were talking about converting waste i.e. crap into energy, I think!
