Las Gaviotas: A Sustainable Community Cut Off From the World Almost 40 Years Ago June 2, 2011

It sounds like something out of a fairy tale or a children’s book, a community deep in the wild jungle of Colombia, cut off from society almost 40 years ago. Then, after the rest of the world turned their back on them, they suddenly take great interest as it turns out this community has found something the rest of the world needs. Energy. And not just a new supply source but something even better. They’ve figured out how to be sustainable without outside influence or resources, reports The New York Times.

In the 1960′s a Colombia developer named Paolo Lugari, while on a road trip through the country, stopped at an abandoned parcel of land and imagined an entire village before his eyes. The land was so poor and the area so remote – “visitors” have to pass Guerrilla check points or fly in to make it there – that no one wanted to live there. Mr. Lugari was in his very early 20′s at the time. He wanted to find one of the hardest places to live and see if he could make it work. This was before the oil crisis of the 70′s, but even then he knew fuel and other resources would be scarce.

Today there are 200 residents and they, “have no guns, no police force, no cars, no mayor, no church, no priest, no cellphones, no television, no Internet. No one who lives in Gaviotas has a job title.” So what do they have? How did this community of 200 people create a society that is now the envy of urban planners, including Amory Lovins, around the world?

When you live in the middle of nowhere, you have to get creative. Initially scientists helped design the buildings, homes, laboratories and factories in the area but don’t come around much these days thanks to all of the violence. Today they have a solar kettle for sterilizing water and solar kitchen, and a 19,800-acre reforestation project with species chosen to produce resins for biofuels, as well as, for creating conditions upon which other native plants can flourish. A children’s seesaw powers the local water pump. Community members feel they are there to “try to lead a quiet life, depending on nothing but our own labor and ingenuity.” Sounds pretty idyllic today.

The reforestation project is one of the most successful in the world, considering that everywhere around it is still a “tropical desert.” To say Las Gaviotas is doing okay for itself is an understatement. People from outside the village trek to Las Gaviotas to earn $500 a month, which is double what they would earn in other rural areas. A mycorrhiz fungus was added almost 20 years ago to help break up and digest the poor soils and in its place other species grew up. They use the resin from the trees to power their motorbikes and tractors and sell the excess. When China dumped cheap resin imports in Colombia, the community was forced to drop their prices by almost 40% to compete.

It might sound like a fairy tale, but Las Gaviotas also has hardships too. Their remote location makes them a likely target for guerillas and organized crime trying to sneak shipments out to other areas, or at least likely that someone trying to hide something will stumble upon them. There are several guerilla and paramilitary groups that are located not too far from Las Gaviotas, but as one resident said, “we don’t take part in this war, and we ask those who enter our village to do so without their rifles. So far, for us at least, this has worked.” Journalists and visitors who have come this year must only stay the day and leave before dark under fear of kidnapping.

Also, the community itself is very small, and with only 12 children in school, many question how long this “experiment” can go on. As many of the residents have said, “we have survived. Maybe, at this time and place in Colombia, that is enough.”

Bacterial Breakthrough Could Lead to Cheap, Renewable Bio-Batteries May 24, 2011

Bacteria can 'breathe' many different substances, incluidng oxygen, minerals and human or animal waste -- which could be an alternate source of power.

You may not think twice about what goes down the drain in your toilet. But soon, what you’re flushing away could turn on the lights in your home.

This unique take on recycling comes from a substantial discovery concerning the way in which bacteria transfer electrical charges — and it could lead to the development of “bio-batteries” or bacteria-fueled electrodes. Eventually, these fuel cells could take human or animal waste and convert it into usable energy.

“The exciting thing is that we really never understood how the electrons were getting on the surface,” Dr. Tom Clarke, one of the lead researchers on the project from the University of East Anglia, told FoxNews.com. “What happens in this process is that bacteria take in organic carbon molecules and ‘chew’ them inside the cell, which then releases electrons.”

The project — funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the U.S. Department of Energy — has revealed how the microscopic molecular structure of bacteria proteins allows for energy transfer.

Multiple layers of proteins inside bacteria essentially act as the cell’s organic power lines, enabling electrons produced within the bacteria to be transferred to the bacteria’s surface. Now that scientists understand what’s happening on the surface, they will be able to produce a cell that can connect to the bacteria.

Then the bacteria can feed off the electrode, and in return, generate electrons.

The process is called iron respiration, but the researchers have colloquially dubbed it “breathing rocks.”

“Bacteria have a whole different arsenal of things to breathe other than just oxygen. They can breathe on mineral oxides, so this process of bacteria sitting on rocks and breathing rocks can be applied to electrodes. Bacteria can breathe on the electrodes and produce electrons.”

There have been attempts to harness electricity on the surface of bacteria before, but lacking the knowledge discovered in this project, only small amounts of energy were able to be obtained. Now sizable amounts of electricity can be put towards practical use.

“It offers a very nice method of getting ecologically sound energy,” Dr. Clarke told FoxNews.com. “You can build these electrodes into places such as waste treatment plants. The bacteria can digest waste material and produce energy.”

Along with running an everyday generator, the discovery could also aid in the cleanup of pollution caused by oil or uranium. And the overall benefit — the bacteria being used for the electrodes — is both plentiful and renewable.

“One of the advantages of the bacteria we’re looking at is they’re found everywhere already,” Dr. Clarke told FoxNews.com. “They actually live in the ground or in very common places. If you look at a lot of the names of what we’re considering, they’re in every single lake already.”

“All we would be doing is changing the surface that they live on,” he said.

Trash Today, Electricity Tomorrow, Thanks to Landmark Solar Energy Farm January 28, 2011

A landfill in Georgia is being converted into a solar-energy generating farm

A landfill in Georgia is being converted into a solar-energy generating farm

DECATUR, Ga. –  Your trash could soon produce enough energy to light a neighborhood.

A landfill in DeKalb County, just north of Atlanta, is being converted from a simple hill of decaying garbage into an power-producing solar energy farm, Fox News has learned.

“It’s very exciting to be a part of this new technology, particularly given the potential for landfills across the country,” said David Stuart of Georgia’s Republic Services.

An enhanced geo-membrane liner, which looks like a large green tarp, covers the surface of the landfill. The liner is then covered with lightweight solar panels that are about 15 inches wide, 18 feet long and only about a quarter of an inch thick.

“We expect to produce 1 MW of power from the landfill — equivalent to providing energy for 150 homes,” he said.

Once the project is complete, more than 10 acres of the landfill will be producing energy.

The installation of the membrane and the solar panels doesn’t disrupt the landfill’s normal process of breaking down garbage. Instead, it serves as a dual-purpose system that produces solar energy while capturing landfill gas for heating homes. A smaller test site was created in San Antonio but this is the largest project of its kind in the nation so far.

“This is unique in Georgia as it represents the first solar energy landfill project in the state and is nearly seven times the size of the project constructed in San Antonio,” Stuart said.

According to the U.S. Environmental Protection Agency, there are about 100,000 closed landfills in the United States. Stuart estimates that hundreds of thousands of acres under those landfills could potentially use this technology to produce energy. Many of these sites are close to urban areas, he said, and have the necessary infrastructure to economically distribute the energy.

The “Green” Wonderland of Dubai, United Arab Emirates November 15, 2008

Filed under: Biofuels,Energy Generators,Solar,Wind — bferrari @ 10:56 pm

By Bob Ferrari

Dubai in the United Arab Emirates is fast becoming “the place to visit and drop a lot of money”. The US is not the only country to figure out that the vast oil reserves of the Middle East are NOT endless. It is estimated that there is possibly 20-30 years left of oil production in the Middle East.

Brilliantly, the UAE leaders acknowledge this and have taken steps to protect their wealth from the pending oil outage. They have taken their vast oil wealth and are using it to develop Dubai at record breaking speeds. Every year there seems to be some development that seeks to out-do the previous record holder, not just in sheer height, but in some other extravagant design concept.

Here is one of the latest. 125 stories, with a turbine (propeller) – and a restaurant in the middle of the turbine, of course – is designed for the Dubai architectural wonderland by the British firm Atkins. As in all the developments in this future-looking city, this one also seeks to be completely self-sustained. A foward-looking-green and self-sustaining future plan that comes from the minds of those that are dripping in wealth from oil. The US needs to think along the same lines, certainly the country that has all the oil is doing so now.

Don’t Let Low Fuel Prices, Fuel Alternate Fuel Complacency

Back in July, when the gasoline per-gallon price was flirting with $4 and a gallon of diesel fuel was well on its way to $5, a wide array of analysts predicted that the high prices would be permanent. Gasoline, many of them said in the spring, would cost $5 a gallon by Labor Day.


Now, with oil prices south of $60 a barrel after peaking at about $145 in mid summer, many analysts predict that gasoline will cost about $2 a gallon by year’s end.

It would be a tragic mistake if consumers and the government, as they have in the past, regard the new prices as permanent. This year has demonstrated that price volatility is truly the permanent feature of the oil market.
