Experiment "Marseille3"
Crate Design #1
Design features:
- Substrate: topsoil gathered from La Friche's garden - two days before assembly - inoculated with 10 mL of clay gathered in Niolon on the day of assembly.
- Volume: 80*30*2 cm3
- Container: crate, covered with a transparent garbage plastic bag.
- Proton Exchange Membrane: printer paper with low amount of ink.
- Surface: 80*30 cm2
- Water comes from La Friche's tap - maybe chlorinated.
- Anode: copper covered with carbon, extracted from a dead DELL PC battery found in the LFO storage space.
- Surface: 70*5 cm2
- Cathode: copper covered with less carbon, extracted from the same battery.
- Surface: 70*5 cm2
Performances:
- Voltage: started at 30mV, went up avove 40, and dropped down to 0 in 2 hours.
- Current: started at 0.125 mA, and dropped down to 0 in 2 hours.
Max Power Measured: 3.75 microW
