We stayed at Curious on Hudson to meet the Envisaj Club from Mercy Collage. This club is run by professor TH Culhane. At his spare time professor Culhane is into mini biogas systems (1 to 20 qm). He is doing development aid with his German NGO "Solar C3ities" in developing cuntries. He writes article for National Geographics as well as for his blog.
On the photo you see TH Culhane (left) filling a demonstration biogas system with duck shit from the local pond.
