London Using Glue to Clean Up Air

The European Union is requiring member countries to have no more than 35 bad air days per year by 2012 or the countries will face fines of around $450 million.  In order to it's great! cialis soft gel clean up air pollution to meet the EU's standards, London is turning to glue.  Well, a glue of sorts.  The English capital is applying a calcium-based adhesive to streets to trap particulate air pollution and, believe it or not, it's working.

The city's street sweepers have applied the adhesive to air pollution hot spots around the city and particulate levels in those areas have dropped 14 percent.  The project has cost the city $1.4 million so far, which is pretty expensive, but 14 percent is a pretty substantial reduction from glue alone and a far cry from a payout of $450 million if they didn't meet the standards.

London will be taking other action to reduce air pollution, including rolling out cleaner buses, retiring the most polluting taxis, enforcing stricter emissions standards and planting trees.

Alaska Airlines Begins Cross-Country Flights on Used Cooking Oil Blend

Last week, Alaska Airlines began a series of cross-country flights from Seattle to Washington, D.C. using a biofuel blend that is can be comprised of used fryer oil, chicken fat, algal oil or parts of inedible plants.  The 80/20 blend of jet fuel and biofuel will carry 75 flights on the trans-continental trek.

The fuel is being supplied by Dynamic Fuels, which counts Tyson Foods as a partner, providing chicken fat and beef tallow from their processing plants.  Alaska Airlines will use the fuel on cialis best price a daily Boeing 737 flight that covers the Seattle to D.C. route, as well as on three daily Q400 turboprop flights that go from Seattle to Portland.

The biofuel is chemically identical to cialis best buy jet fuel, which means the flights could actually run completely on the alternative fuel and not be blended, but right now the cost is prohibitive.  The biofuel blend that Alaska Airlines is using cost it $17/gallon compared to $3/gallon for traditional jet fuel.  But the expectation is order prescription cialis that as production of biofuels like these increase, the prices will steeply drop.

Bloom Boxes Headed to Delaware

Bloom Energy will soon be installing 30 MW-worth of Bloom Boxes in Delaware in what will be the company's largest project yet.

Delaware regulators just approved the plan that calls for a factory to be built for the fuel-cell boxes.  State utility Delmarva Power will raise a large portion of the funds required to finance the project by adding a $1.34-per-month surcharge to its customers' bills.  That surcharge will add up to about $100 million over the what is the cost of cialis next 20 years.

The state is also offering $18 million in incentives and the project hopes to tramadol cheap receive federal grants as well.

Bloom Energy has already found customers in Google, eBay, Adobe, AT&T and through pilot projects with utilities PG&E, Southern California Edison and Tennessee's EPB, but none of these projects come close to the Delaware deal that could grow to as much as 50 MW.

Beyond a cleaner source of energy, the project will bring Delaware 900 new jobs at the factory and $300 million in annual economic activity.

USDA Study Says Wood Is the Greenest Building Material

Green building advocates and construction product marketers have different views of what the greenest building material is. Different ways of determining what green means will lead to different results. But according to a recent report from the U.S. Forest Service, wood is the greenest building material.

This analysis seems to rest largely on the carbon footprint of various construction materials.

"The argument that somehow non-wood construction materials are ultimately better for carbon emissions than wood products is not supported by our research," said David Cleaves, the U.S. Forest Service Climate Change Advisor. "Trees removed in an environmentally responsible way allow forests to continue to it's great! buy cheapest viagra sequester carbon through new forest growth. Wood products continue to benefit the buy prescription cialisbuy cialis in the uk environment by storing carbon long after the building has been constructed."

Wood is also unique as a renewable resource that actively sequesters carbon from the atmosphere. As they grow, trees absorb CO2 from the atmosphere and lock it into the structure of the wood. In doing so, wood is a carbon storage material, and that carbon is locked away until the wood decomposes or burns.

The report additionally recommends that USDA further its outreach efforts to educate the construction industry and the general public to be more aware of the suitability of wood for non-residential construction and to further study of viagra low price the carbon benefits of the use of wood in construction.

Iceland Getting World's First Zero-Carbon Data Center

A new pre-fab data center will soon be heading to Iceland where it will become the world's first to achieve zero carbon status.  The IT company Colt will build the center's 37 components and then ship them off to Iceland where they will be assembled.

The ability for this data center to operate without carbon emissions has everything to do with its placement in Iceland.  The center will be powered exclusively by geothermal and hydroelectric sources and cooling will be taken care of by using the only now cialis fast delivery cold Iceland air.

The 500 square meter facility will only take four months to complete.  It will contain the servers of UK data hosting company Verne.  The facility will be able to supply 100 MW of computer load at any time and the capacity will be expanded as demand grows.
