Here’s the (allegedly) world’s first biodiesel powered arcade. Sorry for the poor picture, but didn’t take my camera as it was raining in London (as is usual on a bank holiday) so this is from my phone. There was just one guy playing pinball in there so I didn’t venture in, but it seems a good idea. Even if biofuel isn’t a realistic solution, for things like this it’s ideal. More (and better pictures) can be found here.
