We Make MFCs

What is an MFC?

Strictly speaking, it's a microbial fuel cell; a combination of the amazing science of Mother Nature and the creativity of scientists and engineers.

The science is driven by natural selection. The technological scaling is the product of hard-core engineering and chemistry.

The result: we use naturally-occurring microbes to solve difficult problems and generate energy.

Natural Aeration

Water is naturally aerated by brooks, rocks, and gravity; that babbling brook oxygenates the water and breaks down organic content. The result: life in the riverbed thrives - a healthy stream, full of bio-diversity.

Natural aeration is the inspiration and basis for modern wastewater treatment...

Municipal Aeration

This is how  Municipal wastewater is aerated - blowing air into water  24/7.  It's very energy intensive (even with newer, efficient systems).  Mechanical aeration uses 3% of US Electricity  (120,000 GWh of power.)  Every year. That equals more than 89,000 Metric Tons (annually) of CO2.

So, although industrial aeration is effective, it's costly. Financially and environmentally. 

Of course, there is another way...

How MFCs Work

A biofilm of naturally-occurring microbes (mostly electrogenic) live on the Anode (left), consuming organic waste and generating electrons.

On the right, our set of proprietary materials are assembled into a conductive cathode, to accept the electrons. (AKA, DC Power)

Notice, rather than aerate all the water, a very small amount of Oxygen is provided to the cathode, as the ultimate electron acceptor. 

The Result:  Microbes treat the waste, as usual. Plus Energy-Positive Wastewater Treatment, without the high power bills.
