Gobar is typically mixed with a roughly equal amount of water, and gravity-fed through a pipe into an airtight underground “digester,” where naturally occurring bacteria feast on the mixture. This anaerobic process produces small but precious amounts of gas. That gas can be fed directly into a heat source, such as a cooking stove, and used to fuel it.
The biogas is 50-70% methane by volume, similar to natural gas, and a convenient source of clean energy. The gas is easily collected and stored for lighting, cooking and other household uses. After bacteria digest the dung, the by-product is a rich organic fertilizer, sometimes called slurry, or bioslurry. That fertilizer is more effective than raw dung, with important benefits for hands-on farmers. For instance, it doesn’t smell bad, and almost all the pathogens and weed seeds have been destroyed.

The Kid – one of the best to ever do it. I’m a Giants fan, but I know I’ll miss Junior Griffey.
Anyway, now that he’s retired, please do not wear your baseball cap backwards.
Wow, Ken Griffey Jr. is retired. I remember getting this exact rookie card for my first holy communion and thinking about how lucky I was. It’s still sitting in my “good card” box at my parents house. I’ve gotta dig this out next time I’m home.
NASA’s Webb Telescope on display at New York City
The life-sized model of NASA’s next generation space telescope is being set up in New York City’s Battery Park for the 2010 World Science Festival, which runs June 1- June 6. The opening ceremony will be held in front of the model on June 1. The Webb telescope full scale model dramatically highlights how far the next generation of space telescopes will be from its predecessors. It’s unlike any telescope you’ve ever seen.
The actual size model is highly detailed. It is constructed mainly of aluminum and steel, weighs 12,000 pounds, is approximately 80 feet long, 40 feet wide and 40 feet tall. It is as large as a tennis court. The model requires 2 trucks to ship it and assembly takes a crew of 12 approximately four days. »
Lt. Gen. Russel Honoré: Take punitive action against BP now
Lt. Gen. Russel Honoré: Take punitive action against BP now
“The No. 1 rule when dealing with disaster is to figure out which rules you need to break. Rules are designed for when everything is working. A democracy is based on trust. BP has proved it can’t be trusted.
The government needs to change the game and make this a punitive effort. The government has been too friendly to oil companies.
The government should immediately freeze BP’s assets and start to charge the corporation — say $100 million — each day the oil flows. The money could be held in a fund that U.S. government draws on to take care of the people along the Gulf Coast and pay the states for doing the cleanup.
Next, BP and the government bureaucrats who broke a law and put the public at risk need »
It’s Official, We Live in the Future
On May 20th, J. Craig Venter and his team at J.C Venter Institute announced the creation of a cell controlled by a synthetic genome in a paper published in SCIENCE. As science historian George Dyson points out, “from the point of view of technology, a code generated within a digital computer is now self-replicating as the genome of a line of living cells. From the point of view of biology, a code generated by a living organism has been translated into a digital representation for replication, editing, and transmission to other cells.”
I feel sure of only one conclusion. The ability to design and create new forms of life marks a turning-point in the history of our species and our planet.
— Freeman Dyson
Clara Gaggero designed this amazing tool to help people learn about technology. She is also giving a talk on Analogue Methods to Bridge the Digital Divide tonight at SVA. I can’t go due to freelance work that’s due, but man oh man do I wish I could.

If you’re someone who only reads the editorial page of The New York Times, try glancing at the page of The Wall Street Journal once in awhile. If you’re a fan of Glenn Beck or Rush Limbaugh, try reading a few columns on the Huffington Post website. It may make your blood boil; your mind may not often be changed. But the practice of listening to opposing views is essential for effective citizenship. So too is the practice of engaging in different experiences with different kinds of people… If you grew up in a big city, spend some time with some who grew up in a rural town. If you find yourself only hanging around with people of your race or your ethnicity or your religion, broaden your circle to include people who’ve had different backgrounds and life experiences.

MIT Researchers…
via constantflux : poptech : electricpower : ichrider
A team of researchers at MIT has just announced that they have successfully modified a virus to split apart molecules of water, paving the way for an efficient and non-energy intensive method of producing hydrogen fuel. The team engineered a common, harmless bacterial virus to assemble the components needed to crack apart a molecule of water, yielding a fourfold boost in efficiency over similar processes.
This could be the moment that changes our future from battery powered to fuel cell vehicles.

I really have no response. Because last I checked, Sarah Palin’s not much of an expert on nuclear issues.
