What We Do
We are an internationally recognized educational non-profit organization bringing clean, free fuel and nutrient dense fertilizer to people around the world. We deliver biogas systems to suburban and urban gardeners everywhere, to farmers in the U.S., and to remote villages and refugee camps around the world. Our mission and educational program is based on the work and vision of Dr. Thomas H. Culhane.

Where We Work
Check out the map below to see where Solar CITIES has implemented biogas education programs – and biodigesters – through “hands-on” workshops. Some of these locations have two or more biodigesters in place, as part of our mission is to have two biogas education “hubs” in each location in order to build continued community learning support.
If you’re interested in working with us to bring biogas to your community, we invite you to get in touch with us directly. We have detailed reports about all of our projects. We would be delighted to share our information with serious enquires about partnership. Please contact us directly to share your thoughts on how we can be of assistance to you.
