Poop Powered MegaWatts

A Chinese Dairy Farm Made The World's Largest Machine For Turning Crap Into Power What happens when a Chinese dairy farm takes the excrement from 60,000 of its 250,000 cows and converts it into electricity ? They generate 5.66 megawatts of power, which is roughly enough to power 3500 American homes. According to Technology Review, Huishan Dairy has created a methane converter that is over 10 times the size of similar such devices. Powered by four of the GE engines pictured above, the converter captures methane from fermenting cow poop and turns it into power. Pop Sci does a good job of summarizing the science behind the converter, which involves processes like hydrodesulfurization and anaerobic digestion, so on and so forth. But what's really interesting here is that the scale of this converter might be more economically appealing to dairy farms in the US. Currently, methane converter in the US only generates 2 megawatts of power, and are only used by 1% of far

Twitter Role on Disaster Relief

http://www.fastcompany.com/1704521/twitter-enables-diy-disaster-relief-in-indonesia      Twitter Enables DIY Disaster Relief in Indonesia BY David Zax Mon Nov 22, 2010 Indonesians, who were the victims of earthquakes, a tsunami, and volcanic eruptions last month, are finding help from an unlikely source: Twitter. Indonesians, who were the victims of earthquakes, a tsunami, and volcanic eruptions last month, are finding help from an unlikely source: Twitter. Indonesia is a country composed of 17,000 islands, and organizing aid relief efforts has proved a challenge, particularly in regions where infrastructure was destroyed, reports Reuters. So enterprising and tech-savvy citizens are taking measures into their own hands, coordinating relief through Twitter. Twitter is extremely popular among Internet-using Indonesians, 21% of whom use the site (compare that to 12% for the U.S.). A group near th
