The Sol Cinema is a tiny, solar-powered movie house that seats eight adults or twelve children. While it might not be the best screen for watching Avatar, I'm sure it will sell out for An Inconvenient Truth 2: When Zombies Attack!
The cinema is a converted two berth caravan from the 1960's commissioned by the media arts charity Undercurrents. It runs on four large lithium ion batteries charged by two 120W solar panels. Undercurrents encourages people to make environmental films.
