Bacteria Man

"Hey Buddy! Nice to see you again, but it´s freezing in here!"

"I am sorry, I forgot you are still refusing to wear a Shewanella Skin. I will turn up the heating. But I still don´t understand why you didn´t try it once at least . You would realize what a waste of energy it is to heat the whole flat just to keep your body warm."

"Don´t bother with me! I will not voluntarily cover my body with bacteria! That´s disgusting!"

"You think you are aseptic as a surgeon´s scalpel right now? There are about ten bacteria for every single cell of your body you are carrying around with you."

"That´s no reason to make it even worse by adding some billions more!"

"You don´t get the point! Bacteria aren´t necessarily harmful to your body. In fact you wouldn´t even survive without the bacteria in your stomach and...."

"No offense, but you seem to have gone a bit crazy about your bacteria suit since you got lost on the last skiing trip."

"Not crazy, just convinced. I was trapped in this glacier crevasse for three days and would have been frozen like a fish stick if I had stopped feeding the bacteria."

"How did you manage to do that anyway?"


"I took blood from myself with the small vials you normally fill with lemonade or whatever is around. So my bacteria could live on the blood sugar."

"There you go again! 'My bacteria'! You sound like they are a part of your body already! Watch out, here comes Bacteria-Man!"

"Well, I-Live-In-The-Past-Man could at least try it himself before distrusting everything new!"
Shewanella Skin
Shewanella Skin
On the search for new energy sources researchers are currently experimenting with electricity generating bacteria. One of the most promising bacteria is the resistant Shewanella species commonly found in deep sea and soil habitats. These Bacteria have the ability to couple metal reduction with their metabolism and develop a maximum growth rate at 35 °C.

The idea behind the Shewanella Skin is to amplify your body functions by interacting with bacteria worn on your body:
The warmest body regions (crotch and axles) are covered with a double membrane to provide a habitat for the bacteria. In return the Shewanella bacteria produce an enzyme that is used in a microbiological fuel cell to convert a sugar containing liquid directly into electricity. The gained electricity is employed to heat up a silver thread that is woven into the fabric and covers the areas of your body that are most sensitive to cooling in a cold environment.
To control the process the suit features a sleeve-integrated display and small refillable tubes that are plugged onto the fuel cell to supply the system with nutritions.
