Fermenting the earth, Wiring the mud.

 Microbial fuel cells (MFC) / mud cells: 
 - fuel cell system powered by bacteria (or other microorganisms)
 - convert chemical energy to electrical energy
 - produce very little, precious electric current
 - energy can accumulate over time (and multiple cells) and discharge at once

 Useful species of bacteria:
 - Clostridium butyricum: common fermenting bacteria found in cheese, soil and the human gut
 - Shewanella oneidensis: versatile bacteria
 - Aeromonas hydrophilia: aquatic bacteria, can metabolise many fuels
 - Geobacter metallireducens: breaks down toxic chemicals, therefore useful in bioremediation
 - Geobacter sulfurreducens: breaks down toxic chemicals, therefore useful in bioremediation

 Mark Tildan: B.E.A.M. Robots (Biology, Electronics, Aesthetics, Mechanics)

 The Miller Solar Engine: yet another way to use a 1381 voltage defector

 LoRa: radio wave communication technique; LoRaWAN (long range wide area network): wireless, low-power communication protocol

 Mud cells > Capacitor > Switch > Arduino
 - mud generates electricity
 - mud sends data (temperature, time frames)

 Discussion: What can be done with the tiny amount of electricity and the data from the mud?
 - Generate a poem that grows over time: can either be online (on a website [on demand], sent via a mailing list) or local / "off the grid" (on an e-ink display, written into the sand with a plotter, on a USB stick...)
 - Extract sounds from the mud and play them with the help of the electricity
 - Think about collaboration and collectivity!

 Output (by Youjung, Mikki, Raimundo and me): Mud-cell Poem (1.0 ?)

Fermentation Workshop / Tasting / Story Sharing

- Fermentation: umbrella term for chemical processes that involve microorganisms (bacteria, fungi, yeasts); conversion of carbohydrates to alcohol or organic acids

- Pickling: can be fermentation (anaerobic fermentation in salt water), or not (immersion in vinegar)

- Zymology: science of fermentation

- Leuconostoc mesenteroides: a lactic acid involved in fermentation (of vegetables) > "The Legend of Luca"

- Saccharomyces cerevisiae: first used for brewing beer, then also for baking bread; refined over centuries through advancements in microbiology (ability to produce pure yeasts)

- Lactobacillus (genus): first discovered in milk products; also very common in vegetable fermentation

- "Do you consider fermentation to be very spiritual?"

- Rotterdam DIY fermentation kit: "Rotpot"
