Researchers from Ohio State University have shown that the fermented, liquefied feed extracted from a cow's stomach can produce about 600 millivolts. The juice comes from the rumen, the biggest portion of a cow's stomach. Unlike converting methane from cow shit into electricity, a method that requires expensive gear, this method generates electricity as the microorganisms in rumen fluid break down the complex carbohydrates in roughage. From a press release:
While rumen fluid itself won't be used as an energy source, some of the microorganisms found in the fluid are also found in cow dung, which may prove to be a good source for generating electricity. In fact, in a related experiment, the researchers used cow manure directly to create energy for a fuel cell...
This study represents the first time that scientists have used cellulose to help charge a fuel cell....
(The) output reached a consistent maximum of 0.58 volts. After about four days, the voltage fell to around 0.2 volts, at which time the researchers added fresh cellulose to bring the voltage back up to a higher level.
“While that's a very small amount of voltage, the results show that it is possible to create electricity from cow waste,” (bioengineerin Ann) Christy said.

I asked Amy Parness, the co-founder of Sparkle Labs, maker of fantastic educational electronics kits, to write a Medium post about gender and the business of being a maker business person. Her terrific essay calls out the problems with “pink girly engineering kits.” From Medium:
Zero UI is the new term for “invisible interfaces”—what happens in the future when all the clicking and tapping and typing is history: “If you look at the history of computing, starting with the jacquard loom in 1801, humans have always had to interact with machines in a really abstract, complex way.” [Fast Company]
