Media Files====Experiment "Marseille3"==== These experiments have been conducted during the open workshops of the [[http://reso-nance.org/whattheflok/accueil|What the Flok ?]] festival taking place in Marseille, from Septembre 29th to October 4th. ====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 ====Crate Design #2==== __Design features__ * **Substrate**: mud gathered from La Friche's garden on the day of assembly. * Volume: 80*30*2 cm3 * **Container**: crate, covered with a transparent garbage plastic bag. * **Proton Exchange Membrane**: three to four overlapping sheets of newspaper, covered in ink. * Surface: 80*30 cm2 * **Water**: mainly rainwater from the mudsource, with some tap water (0.5L) to complement - 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__ Performances on Day0: * **Voltage**: around 5 mV. * **Current**: around 0.1 mA. Performances on Day1: * **Voltage**: around 45 mV. * **Current**: around 0.1 mA. Performances on Day2: * **Voltage**: around 130 mV peak. * **Current**: around 0.5 mA peak. * Strange measurement behavior: * Voltage starts at 80 mV, and builds up to 130 mV in about 15 minutes. * Current starts at 0.7mA and drops to 0.3mA in about 15 minutes too. **Peak Power Measured**: 65 microW. **Max (stable) Power Measured**: 39 microW Please fill all the letters into the box to prove you're human.
