Alaska Airlines Begins Cross-Country Flights on Used Cooking Oil Blend
Written by Megan Treacy on 15/11/11   


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 www.smartersecurity.com inedible plants.  The 80/20 blend of jet fuel and generic form of viagra 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 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 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 buy levitra now expectation is that as production of biofuels like these increase, the prices will steeply drop.

Renewable Energy Projects Around the World: How Much is Installed and Where
Written by Megan Treacy on 14/11/11   


The Economist has put together a nice graphic using data from Enel showing exactly how many gigawatts of each type of renewable energy were installed as of 2010 and where that power was located. As of the end of last year, the world had a total of cngnewengland.com 1,313 GW of installed renewable energy projects.

As of 2010, hydropower was still the global leader of renewable energy sources with 1,005 GW installed, but that could change in the coming years.  Hydropower only increased in installed power by 3 percent from 2009, but solar power had the biggest year over year increase with a jump of 70 percent from 2009 to 40 GW.

Wind power also added a nice 24 percent in installed capacity from 2009 to 2010 and comes in second place globally, albeit a pretty distant second.  If those trends continue, solar and wind power could catch up in the near future.

The greatest concentration of renewable energy projects are located in Europe, which accounts for 433 of the 1,313 GW.  Asia is a close second with 420 GW and will likely eclipse Europe soon.  Asia had the biggest growth in renewable energy installations with a 30 percent increase from 2009.

North America had 251 GW of renewable energy projects installed at the buying levitra in the us end of 2010.

Turning Commercial Jets into Hybrids
Written by Megan Treacy on 10/11/11   


A company called WheelTug has devised a way for commercial airplanes to run on electricity at slow speeds, much like a hybrid vehicle does.

The WheelTug system includes a pair of electric motors embedded in an airplane's nose wheel which provide power for backing the plane away from the gate and for taxiing up to 28 mph. The electricity for the motors is provided by the auxiliary power unit of the plane, a small engine located at the back of the aircraft used for running lights and the ventilation system when the follow link discount generic viagra main engines are off.

The auxiliary power unit uses only about half a gallon of cialis shop fuel per minute compared to two gallons per minute for each of the main engines.  The WheelTug allows a plane to taxi without use of the main engines and to back from the gate without the help of a diesel-fueled tug, cutting down significantly on fuel use while a plane is on the ground.

Another advantage to creating hybrid jets is that planes will spend less time on the ground since they won't have to wait for a tug.  Also, by running the main engines less, engines will sustain less damage.

The company has just signed a deal to cheap cialis soft outfit 20 El Al jets with the system and buy real cialis hopes to get certification from European and American aviation regulators by early 2013.

California Hits 1 Gigawatt of Rooftop Solar
Written by Megan Treacy on 09/11/11   


According to a new report by Environment California, a major solar power milestone has been reached in the state:  it is now home to 1 gigawatt's-worth of rooftop solar power.  To put that into perspective, only five countries have hit the 1 GW mark in solar power so far:  Germany, Spain, Japan, Italy and the Czech Republic.

The electricity produced by rooftop solar power installations in California now equals two coal-fired power plants and could power 750,000 homes.

The solar installations include new and existing homes and commercial buildings, and panels connected to the grid by both large utilities and smaller municipal utilities.

The report gives most of tramadol cod saturday delivery the credit to a statewide rooftop solar incentive program called the California Solar Initiative.  The initiative is responsible for 600 MW of installed solar power in the state.

Facebook Adding Solar Power to New Headquarters
Written by Megan Treacy on 08/11/11   


Facebook, a company that so far hasn't done much in the "green" arena, is incorporating a nice-sized solar power system into their new headquarters.

The cogeneration system, which is being built by Cogenra Solar, will include both solar PV and solar hot water heating and have far greater efficiency than just a solar PV system alone.  The 24-module system will reside on the roof of a 10,000 square foot fitness center, providing electricity for the fitness machines and hot water for the showers.  The system will have a capacity of 10 kW of electricity and about 50 kW of thermal energy.

Facebook sees this as their initial investment in solar power and hopes to expand the try it levitra canada online pharmacy system later on to good choice order levitra pill include powering and heating other parts of the campus, like the cafes.

Solar Ship Is Half Airship and Half Flying Wing
Written by Philip Proefrock on 07/11/11   

Incorporating solar power onto airships is not an entirely new idea, but we continue to find interesting developments of the concept. The latest is the Solar Ship,a hybrid aircraft that merges buoyant lifting and levitra prescription aerodynamics as well as thin-film solar panels. The combination makes for a long-range vessel that is able to take-off and land on very short airfields.

Earlier studies have been critical of the efficiency of airships, finding that trucks offer a lower overall cost in time and energy. But that presupposes the existence of a network of look there levitra next day delivery available roads. While developed areas may be more readily served by trucks, they are less than ideal for many other parts of the world.

The Solar Ship concept was specifically developed for use in areas without a network of roads available. The two areas being focused on at present are to provide medical services in remote areas and to provide cargo transport alternatives to the "ice roads" presently used to move supplies in the high Arctic.

"Solar Ship blends the technologies of aerodynamic lift, aerostatic lift, and solar cells to create a cost efficient, long range, energy efficient cargo carrier for areas with minimal or unreliable infrastructure."

As a heavier-than-air craft, the Solar Ship does not need to have a ground crew to help support the craft at each destination point. The buoyant assitance of helium gives the craft enough help that it is able to use a soccer field as its airstrip. A solar powered Solar Ship will have unlimited effective range, while the generic viagra without prescription paypal hybrid version increases the cargo capacity while still providing great range.

Saving Land with Floating Solar Panels
Written by Philip Proefrock on 07/11/11   

A water treatment plant in New Jersey has gone solar with an unusual floating array of solar panels. Because the water treatment facility is located on a protected site there was very little land available for construction. Floating the solar panels on the reservoir was the best way to add solar power to the facility.

According to New Jersey American Water, the installation at the Canoe Brook Water Treatment Plant is the first solar array on a body of water designed to withstand a freeze/thaw environment. The installation comprises 538 modules on a floating structure that is designed to rise and fall with the water levels in the reservoir.

The panels are expected to provide about 2 percent of the plant's energy needs, resulting in about $16,000 in energy cost savings annually. The company press release notes that this is part of a $1.35 million dollar pilot project undertaken by the utility. That may not be cost effective even in the lifetime of buy viagra online viagra the solar panels. But perhaps the infrastructure investment will help pay off in other long-term benefits.

Climate Change May Be Super-Sizing Birds
Written by Megan Treacy on 03/11/11   


Researchers from San Francisco State University and Point Reyes Bird Observatory believe that among the wide array of consequences and adaptations that are occurring with climate change, birds are getting larger and legal online viagra fatter.

The team analyzed data from thousands of birds that were caught and released over the invens.nl past few decades in the San Francisco Bay and Point Reyes National Seashore area and found that birds, on average, had increased in mass and in wingspan over the past 27 to 40 years.

The researchers believe that climate change could be leading to this super-sizing of the birds in a couple of ways.  One is that birds could be storing more fat to survive the harsher winter storms that have become more common as the world warms.  The other cause may be that climate change is affecting plant growth in a way that is leading to fatter birds.

While this doesn't seem to be a negative development so far, the researchers say these type of discoveries make it necessary to understand why some plants or animals are getting larger and some smaller and what the real impact of those changes could be.

Huge Sahara Desert Solar Project to Break Ground Next Year
Written by Megan Treacy on 02/11/11   


The massive Dersertec Initiative, which will include several solar power plants constructed in the Sahara Desert, as well as parts of the MIddle East and Europe, is coming together as planned.  The first plant, a 500-MW concentrated solar installation, is now set to break ground next year.

This first plant will be located in Morocco and buy viagra online order cost about $2.8 billion and will take two to four years to complete.  The first phase of the plant will be 7.4 square miles and have a capacity of 150 MW.

The Dersertec Initiative is being funded by a large consortium of European companies and organizations.  The huge project is expected to provide 15 to 20 percent of Europe's electricity needs by 2050, while also providing electricity to the Middle East and Northern Africa.

Northeast States Teaming Up to Build EV Charging Network
Written by Megan Treacy on 31/10/11   


The West Coast has wasted no time building electric vehicle corridors, but so far the Northeast has lagged behind on electric car infrastructure, especially considering the size of the population there.  Luckily, the lagging behind will soon end.  A new regional initiative called the Northeast Electric Vehicle Network will bring together 11 states plus Washington, D.C. to build an electric car charging network.  The network plans to bring hundreds of chargers online over the next couple of years to encourage adoption of EVs in the region.

The states participating are Connecticut, Delaware, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Vermont. Maine will be represented on a city level instead of statewide.  The states will team up with automakers, both large retailers and small shops and charging network companies to work on placing charging stations in the most convenient locations.

Out of the 15,000 EVs currently on the road in the U.S., surprisingly only about 1,000 of them are in the Northeast.  These states want to encourage more EV use not just for environmental reasons, but also because it will save them money.  The Northeast imports about 25 billion gallons of oil each year, so if all-electric vehicles replaced just 5 percent of conventional ones, the region could save $4.6 billion every year.  I'd call that a win-win.

If President Obama's call for one million plug-in vehicles on the road by 2015 comes to fruition, based on population, about 200,000 will be hitting Northeastern roads.  Good thing those drivers will have a place to charge up.

High-Tech Programmable Thermostats
Written by Philip Proefrock on 30/10/11   

A couple of high-tech programmable thermostats are starting to draw a lot of just try! canada pharmacy attention for raising the http://www.umlauf.de/viagra-profesional bar for both style and purchasing cialis user friendliness. Proper use of a programmable thermostat is one of the best ways to control your home energy usage and reduce energy costs, and these new thermostats can make it easier than ever to accomplish this.

Both the ecobee and the Nest thermostats come in stylish packages that offer wireless connectivity, user-friendly interfaces, and online access and mobile apps to let you control your system remotely.

The Nest thermostat is designed to learn and adapt itself over time, so that your house is at the temperature you want when you want it without having to fuss with reprogramming it. The ecobee web interface also gives you energy reports so you can see when you are using energy.

Both thermostats are priced in the range of a few hundred dollars, which is more than the average programmable thermostat, but they offer more features and easier accessability, which presumably should translate into greater energy savings. If using one of these thermostats helps save as much energy as they claim, either one would be well worth the investment, and should pay back its cost with energy savings within a couple of years.
