WWF: 10-feet-long catfish threatened by dams

This Mekong giant catfish was caught in Chiang Khong, Thailand, in 2005 and weighed in at 645 pounds. It was nearly nine feet long and is listed as the world's largest freshwater fish ever caught. Based on it and other giant catfish, experts estimate a fully mature male can be 10 feet long and weigh more than 700 pounds.Four of the world’s largest freshwater fish species — including a catfish 10 feet long — face extinction if dams are built on the Mekong River, the WWF warned Tuesday.

How Brazil Cut Deforestation Rates to Record Lows
deforested-field-amazon.jpg

Traveling from the heart of the Amazon rainforest to the Tropical savannah climate of the Brazilian capital of Brasilia offers a lesson in contrasts — patches of forest and deforestation are replaced with monolithic white government buildings, poor villagers of the Amazon with well-dressed politicians and businesspeople. But as little as these two places have in common, policies and practices enacted in Brasilia will be key in determining the fate of the Amazon. That said, I recently had the chance to sit down with the director …

For years, the students of Dan Rockhill’s Studio 804 at the University of Kansas School of Architecture, Design & Planning has been turning out stunning modern green prefabs, placing them in challenging areas of Kansas City and selling them fast to modern design devotees who know a bargain when they see it- quality materials and construction, operating costs and great modern design. But Wendy Koch of USA today writes that the two latest homes are stuck on the market withou… Read the full story on TreeHugger

Summer Project-Make Herb Garden Out of Soda Bottles
Here’s another fun little project for urban gardeners. This Urban Gardener takes used soda bottles, turns them upside down, attaches duct tape and twine to the top. He fills it with the appropriate soil for whichever herb he is going to plant in the upside down soda bottle herb garden:

Move over Veggie Diesel as Veggie Hydrogen is on the Way

When gasoline prices moved over $4 per gallon a couple of years back and diesel fuel was over $5 per gallon there was great interest in finding alternatives. One alternative that had been around for years was to recycle used vegetable oil from restaurants for use in diesel powered vehicles.

On of the main complaints about doing this was that the exhaust of such diesel powered vehicles smelled like French fries. Now, researchers at the University of Leeds, UK have a new use for this waste veggie oil and that is to make hydrogen out of it.

According to Bioscience Technology, “Dr. DuPont and colleagues have perfected a two-stage process that is essentially self-heating. To begin, the nickel catalyst is blasted with air to form nickel oxide – an ‘exothermic’ process that can raise the starting temperature of 650 degrees by another 200 degrees. The fuel and steam mixture then reacts with the hot nickel oxide to make hydrogen and carbon dioxide.

“The researchers also added a special ‘sorbent’ material to trap all the carbon dioxide produced, leaving them with pure hydrogen gas. This trick eliminated the greenhouse gas emissions and also forced the reaction to keep running, increasing the amount of hydrogen made.”

Of course this latest development won’t make diesel enthusiasts happy, especially the ones that get their used fast food restaurant grease for free. But, hydrogen is non-polluting and will not clog the atmosphere with the smell of French fries and that alone has to be worth something.

Urine: Waste product or future power source?
Researchers in the UK are looking into the use of urine as the ‘fuel’ for microbial fuel cells (MFCs), which use bacterial cultures to break down ‘food’ to create power. MFCs are a developing technology used to power autonomous robots.

U.S. Utilities Get Solar Power Tour of Japan

U.S. utility companies explore Japan for solar energy inspirationWhile the fossil fuel industry continues to wreak havoc over the American landscape in pursuit of coal, oil, and natural gas, U.S. utilities have started to make a collective shift toward safer and more secure sources of energy.  Last spring, a utilities industry research group partnered up with the new Solar Technology Acceleration Center to push solar energy development forward. This week, the Solar Electric Power Association (SEPA) sent a group of top utility executives on a solar tour of  Japan in order to learn more about integrating solar energy into grids and communities.

You can get a blow-by-blow account of the solar tour by following @JuliaHamm on Twitter, so let’s put that aside for a moment and focus on SEPA, which is a non-profit that works to promote solar energy to the utility industry.  Naturally its board includes solar industry companies such as Kyocera, but it is also top heavy with utility industry executives.  It provides an interesting snapshot of how far utilities have come, and how far they have to go.
