The "Park Spark" poop converter is actually two steel, 500-gallon oil tanks painted a golden yellow, connected by diagonal black piping and attached to an old gaslight-style street lantern at the Pacific Street Park. Boston artist Matthew Mazzotta, who is not a dog owner, got the idea after he visited the park with a friend in 2009. Mazzotta had recently traveled to India and saw people there using poop in so-called "methane digesters" to cook food. As he watched the park's trash can fill with bags of poop, he remarked to his friend, "In other countries, they use that." Instead of putting bags of poop in the trash bin, signs on the tanks instruct owners to use biodegradable bags supplied on site to pick up the poop and deposit it into the left tank. People then turn a wheel to stir its insides, which contain waste and water. Microbes in the waste give off methane, an odorless gas that is fed through the tanks to the lamp and burned off. The park is small but has proven busy enough to ensure a steady supply of fuel. Burning the methane, which is 30 times more potent as a greenhouse gas than carbon dioxide, helps the environment. With dogs dropping tons of poop in cities everywhere, Mazzotta thinks the idea of using its untapped power has broad appeal.The project was funded by a $4,000 grant from Council of the Arts at the Massachusetts Institute of Technology, where Mazzotta earned a master's degree in visual studies last year. ]]> main_poo_0

Fresh & Easy Neighborhood Market will open its second GreenChill certified store at Oceanside Blvd. & College Blvd. in Oceanside, California on Wednesday. Two weeks ago, Fresh & Easy opened its first GreenChill store in Rosemead, California, which was also the first grocery store in Southern California to utilize a CO2 refrigeration unit.

EPA's GreenChill Partnership works with food retailers to reduce refrigerant emissions and decrease their impact on the ozone layer and climate change. Under the agreement with the EPA, Fresh & Easy works to achieve to the following:
  • Transition to refrigerants that have a lower environmental impact;
  • Lower refrigerant charge sizes and eliminate leaks; and
  • Adopt green refrigeration technologies, strategies, and practices.
According to the Environmental Protection Agency, GreenChill's food retail partners have refrigerant emissions rates 50% lower than the EPA-estimated industry average. If every supermarket in the nation reduced refrigerant emissions down to GreenChill's average, they could prevent the equivalent of 22,000,000 metric tons of carbon dioxide from entering the atmosphere every year. That is equal to the annual greenhouse gas emissions of 4.2 million passenger vehicles. In addition, these stores would save over $100 million every year, which would help customers save money too. Fresh & Easy worked closely with partners Kysor/Warren and Southwest Refrigeration on the Oceanside store, which earned its silver certification award from the EPA GreenChill Partnership by meeting tough benchmarks for cutting emissions that harm the earth's protective ozone layer and contribute to global warming. Fewer than 40 of the nation's 35,000 grocery stores have received GreenChill Store Certification awards. On average, Fresh & Easy stores use 30% less energy than a typical supermarket – helping save customers money while helping the environment. Fresh & Easy uses LED lighting in external signs and freezer cases, offers customer recycling in every store, and uses advanced refrigeration and freezer units to cut back on energy usage. Steve Hagen, Fresh & Easy's Director of Procurement presenting at the FMI Energy & Store Development Conference said today, "In addition to our efforts to reduce refrigerant emissions, we also are working on innovative ways to save energy, such as utilizing skylights, LED lighting and technological advancements like EnviroTower, which saves a significant amount of water in our stores.]]>

Lake_Kivu_picture_from_Nasa

Rwanda’s Lake Kivu is on the doorstep of Nyurangongo volcano, making the lake’s waters the secret hiding place for thousands of years worth of volcanic gases. The Rwandan government recently built a power plant on the lake’s shore, producing 3.6 megawatts of electricity. This is enough to power more than 4 percent of the country. Doesn’t seem like much, but plans are to utilize more of the Lake Kivu’s dynamite power to provide one-third of the country’s energy needs.  There are worries that as global warming increases, the warmer surface temperatures of the water could release the toxic gases. But if the plant keeps using and providing an outlet for the toxic gases, this will prevent a dangerous build up of the gases underneath the lake’s surface.

You need to store electricity because wind and solar power is intermittent."]]> energy

Scientists at the University of St. Andrews in Scotland have developed the world’s first battery fueled by air. This battery has 10 times the storage capacity of conventional batteries and could pave the way for changes and innovations in things like mobile phones, laptops and electric cars. It’s much lighter than current batteries as the main chemical in traditional batteries, lithium cobalt oxide, is replaced with carbon and oxygen. This also helps to recharge the battery as it’s used, perhaps signifying the death of the phrase, “my battery’s dead”. Professor Peter Bruce of the Chemistry Department at the University of St Andrews, said in the Telegraph: “The benefits are it’s much smaller and lighter so better for transporting small applications… Storage is also important in the development of green power. You need to store electricity because wind and solar power is intermittent.”
