Electrolysis Catalyst Could Produce Inexpensive Hydrogen
Written by Philip Proefrock on 14/04/13   

Two Canadian researchers have announced a breakthrough that could produce catalysts for electrolysis at a fraction of current costs. The University of Calgary scientists are working to commecialize their discovery by 2014.

The FireWater Fuel (FFC) catalyst is paradigms.com.do more efficient at releasing breaking water into hydrogen and only for you viagra discussionsdiscount priced viagra oxygen, and can be produced at a fraction of the cost of other exotic material catalysts. The FFC catalyst is based on ferrous oxide - rust. And, according to womans levitra the researchers, the cost could be 1000 times lower than the cost of current materials.

With an efficient and inexpensive means for cracking water into hydrogen and oxygen, the feasibility increases for fuel cell batteries that can readily charge from renewable sources such as wind and solar when those sources are available and then discharge to provide electricity when demand is high.

The electrolytic catalyst is just one of the components that would be required for an entire system, but it has been an exepensive component of the system. With the FFC catalyst, hydrogen power takes another step towards being a greater part of where to buy viagra the power mix in the coming years.

Former EPA Chief to Lead Apple's Environmental Policy
Written by Philip Proefrock on 19/06/13   

Apple has recently hired former EPA chief Lisa Jackson to be its new Vice President for Environmental Initiatives. While the link for you cost cialis company has had a strong environmental record, Apple has been criticized in recent years for some of cheap viagra online its practices, including producing and briefly leaving EPEAT.

Greenpeace sees the good in Jackson's hiring, calling her, "a proven advocate with a track record of combating toxic waste and the dirty energy that causes global warming..."

The question is whether Jackson is coming on board to continue to push things forward in groundbreaking new ways, or whether her administrative background will have her instead leading an effort of well-spun greenwashing. Her political background might seem to suggest the latter, although her career at EPA included steps to tramadol with no perscription overnight regulate greenhouse emissions. We hope her tenure at Apple is that of a true ecogeek, and that Apple continues to improve its environmental record.

Are Cities More Sustainable Than Suburbia?
Written by Sarah Rich on 30/08/13   

Is living in the city inherently greener than living in the suburbs? Researchers like Edward Glaeser have argued a resounding yes: “In almost every metropolitan area, carbon emissions are significantly lower for people who live in central cities than for people who live in suburbs.” This conclusion has common sense on its side. Despite the literal greenness of many suburbs, high density living would seem to reduce energy use by default: less car and fossil fuel dependency, more infrastructure efficiency, with the largest cities generating the overnight levitra generic biggest energy-saving boost.

But new research from Canada’s Dalhousie University contests the claim that cities are immensely greener than their suburbs and adds additional information to consider when comparing population density and www.diabetes.org.br emissions. Researcher Jeffrey Wilson and his team looked at greenhouse gas emissions around Halifax, Nova Scotia, and found a negligible difference between suburban and city pollution: only a 0.3kgCO2e/person/day difference. While suburbanites did drive more, those in the city produced more home-energy emissions per household member than their suburban counterparts, bringing their total emissions closer to each other. Exurbs dwellers, however, needing to travel the furthest, polluted the most. Those in the exurbs produced 11 percent more emissions than those living in the inner city.

This research does broaden the conversation, illustrating that not all cities necessarily have a significant environmental edge over their suburbs. As Eric Jaffe at The Atlantic Cities points out, however, the study has a few problems: it doesn’t account for income level (the wealthier exurb dwellers may emit more greenhouse gases in part because they have more disposable income), and doesn’t compare the data by season--only across a year. Additionally, while Halifax Regional Municipality’s suburbanites and urbanites might be similar in greenhouse gas emissions, its hard to know how much this can speak to other regions’ internal relationships when other studies have looked at more metropolitan areas.

​Multi-Technology Synergy to Grow Food in the Desert
Written by Philip Proefrock on 20/06/13   

A project in Qatar is http://www.karlbarth.nl/uk-viagra-sales putting together a number of different systems in a complex project intended to "produce food, fresh water and clean energy in deserts using seawater." The Sahara Forest Project uses a number of different systems where the waste by-products from one process are used as feedstock for another. It began by focusing on what was readily abundant: seawater, sun, and desert sand, and looking to what was needed: food, energy, and clean water.

"The seawater, pumped from the cialis for sale cheap nearby Persian Gulf, is the system’s lifeblood. It’s used to cool and humidify the greenhouses. It’s also used to grow algae to produce biofuel, with the leftovers from that process going to make animal feed. Some of it is transformed into fresh water by a solar-powered desalination unit. Some of it may even be used down the road to purchase cialis from us raise fish or shrimp."

The project greenhouse is fed with CO2 from a nearby fertilizer plant, which helps reduce the atmospheric emissions from the manufacturing process as well as providing an environment in which the plants thrive. Seawater is also pumped into the greenhouse to provide evaporative cooling and higher humidity.

"The project’s designers say the concept should work in any low-altitude desert area near a large source of salt water." Addressing the it's great! viagra online buy many needs found in these regions of the world makes this an especially compelling project.

The greatest hindrance to this project is its high cost, though the prototype is being funded by Qatar. In the long term, the lessons from this pilot project may be able to be deployed in the many areas around the world where inhospitable deserts can be brought to life.

An audio story about the project along with further images at TheWorld.org provides further information about this complex, intriguing experiment.

First Container Ship Crossing the Northern Passage
Written by Philip Proefrock on 04/09/13   

For the past few years, the Arctic has been sufficiently ice-free in the summertime that some ships have been able to take the cheap cialis online without a persciption short-cut routes across the North Sea Route and www.enshift.com the Northwest Passage. Last year, among others, a small sailboat with a crew of 3 made the Northwest Passage. This year, a 19,000 ton Chinese cargo container carrier is traveling to Amsterdam via the Arctic, going north and traveling along the northern coast of Russia, rather than down through the Indian Ocean and through the Suez Canal and the Mediterranean. This marks the first time that a container ship is cheap generic viagra from india traveling through the Arctic.

The shorter trip will mean lower fuel costs (and, ironically, fewer greenhouse gas emissions) for the freighter. Taking this route is expected to save 12 to 15 days of travel and shortens the www.diabetes.org.br trip by roughly 7,000 kilometers (4,350 miles).

While this is news now, it is all too likely that this will go from a unique occurrence to generic price viagra an ordinary annual event within a few years.
