-====Microbial Fuel Cells====
+====Quick & Dirty Microbial Fuel Cells====
+A Microbial Fuel Cell (MFC) is a renewable electricity source based on soil microbial life. Anaerobic bacteria (living without oxygen) are produce electrons we can harness to feed our electrical circuits. It is a low-power energy source, working fine for lighting, or communication circuits sending data at low frequency.
+MFCs are the object of advanced studies in many laboratories across the world. My objective is to design a MFC which can be build by anyone without specific prior knowledge out of abundant waste or bio- materials found in his/her close environment. The power is this quick & dirty MFC should be able to power a low-power LED.
+I am currently playing with parameters: sample source, design geometry, electrode materials, nature of the proton exchange membrane (PEM), water source... To understand better the drivers of electrical power delivered by these Quick & Dirty MFCs.
+So far, the peak power I measured was 0.5 mW [[michka:research:microbial_fuell_cells:Bruxelles2|during my experiments in Brussels]], which is still not sufficient.

 ===Sludge===
-   * Could we use compost tea as a sludge source ? Does it also work with usual soil ?

+     * See [[michka:research:microbial_fuel_cells:Bruxelles2|here]] for performances obtained with compost tea.

    * How can we keep feeding the sludge, to make the fuel cell operation continuous ?
