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.

The Cobham catalog, exposed by The Intercept, features countless pages of surveillance gadgets sold to U.S. police to spy on American citizens: tiny black boxes with a big interest in you. In the creepily bland feature lists and nerdy product names is a whisper of a dark future; perhaps darker than anyone can imagine.

The Atmos R2 may be bigger than the brand’s previously-released vapes, but we argue that in this case it’s definitely a good thing. A bigger heating chamber means more room for packing it full. And the bigger battery means longer, more fulfilling vape sessions. In fact, you can use the Atmos R2 for up to about 25 […]
