Rehoming the PCGS Biodigester

Biodigester

Biodigester (Version 1) in CGS 134

After years of sitting proudly in the CGS 2nd floor lobby, the original Version 1 Biodigester, built by Dr. Culhane and his PCGS students, is moving to its new home in CGS 134. This iconic model will now reside in the classroom where students can learn firsthand how food waste turns into renewable energy.

Biodigester - Version 1.0

The "Domestic Dragon" started in Netanya, Israel. Dr. Thomas Henry Culhane visited the company called Home Biogas in Israel,which provided him with a simple box of biodigester equipment for him to build the system and figure out what was to be included in the manual.  After that experience, Culhane ventured into the Negev Desert, visiting Bedouin villages where T.H. and company assembled and installed similar systems.

How Biogas Works

At first glance, a Home Biogas system looks like a large plastic bag filled with liquid. But inside,through biological processes, these food scraps turns into natural gas. As a byproduct, the biodigester produces liquid fertilizer perfect for gardening.

Bringing Biogas to Different Communities

After the success of Version 1, then came versions 2 and 3 of the biogas systems, which further expanded the reach. Culhane traveled across Israel and the West Bank,installing these systems. But one of the most remarkable experiences was bringing the technology to a refugee camp in Jordan.

Biogas in a Refugee Camp

One of the most impactful moments was bringing the technology to a refugee camp in Jordan, where political barriers prevented some of Culhane's Israeli colleagues from crossing the border. Culhane, however, carried the equipment through customs, delivering biodigester technology to people in need.

Biogas Arrives in Tampa

Today, these biodigester are making their way to Tampa, Florida, bringing the benefits of renewable energy to U.S. communities. Over 80 households in Tampa will soon have access to biogas setups, allowing them to convert food scraps into gas for barbecuing or composting in their backyards - a direct result of the work the PCGS students have been doing over the years.
