EcoDairy in Abbotsford, BC (Canada) has a Chademo charger that they run from an anaerobic digester, 'fed' by cow manure from the same farm. The owner came up and spoke to me - apparently we were the first to ever charge a Tesla there. He wasn't aware that Tesla's can use Chademo. Actually a really nice place for a stop with picnic tables etc. Smells a little bit at first... for obvious reasons, but you get quickly used to it.
