Fossil Fuel Free Cargo Ship

-2Cargo ships are a very efficient means of shipping cargo in terms of cost and cialis buy energy per ton of freight moved. But the usefull link buy levitra online uk ships use some of the dirtiest fuel, and global shipping is real cialis responsible for 3-4% of all greenhouse gas emissions. So, while cleaning up ocean freight isn't the sole solution to atmospheric greenhouse gasses, it's an area that could stand some improvement.

One solution may come from B9 Energy, the largest independent operator of wind farms in the UK. B9 is now venturing into shipping with a carbon neutral cargo ship that is due to set sail in 2012. At only 3,000 tons, this ship will be considerably smaller than a typical bulk freighter, which tends to be in the range of 15,000 to 30,000 tons. But, unlike a typical freighter, it will be carbon neutral. 60% of the ship's energy is to be provided by sails, just like the clipper ships of the 1800s. The remaining 40% of the ship's energy will be provided by engines running on liquefied methane produced from biogas sources. If demand for biofuel outstips supply, the ship can also be run on liquefied natural gas.

The prototype vessel is expected to wow it's great how to buy levitra cost about $24.4 million. If the ship proves successful, as many as 50 more might be built.

On-Site WInd Power Provides 100% of Power to Data Center

eg-wind-owcWe've heard of buy cialis online cialis data centers that are running on green power, though these are often mostly done through buying energy credits for distant generating facilities. But Woodstock, IL-based Other World Computing is the first to have 100% on-site wind power to run its operations. The 39 meter (128 foot) diameter, 500 kW turbine is expected to generate an estimated 1,250,000 kilowatt hours (kWh) per year. This is more than twice as much electricity as is order levitra in new zealand used by all of OWC's operations. The facility is grid-tied, and will sell the excess power back to the local utility, as well as being able to utilize grid power as backup during slack wind periods.

Not only is this facility generating more electricity than it needs, the building that houses OWC is also anticipating LEED Platinum certification. A few of the features of the building include energy efficient ground-source heat pump systems for heating and cooling, rooftop fiber-optic light harvesting for lighting, occupancy sensors, water efficient fixtures throughout, and a company-wide recycling program. An interactive map gives more detail about all of the various ways they have optimized the facility to reduce resource use and improve energy efficiency.

Some purists might complain that OWC's operations are not exclusively wind powered because of the grid connection and its use as a backup system. However, grid distribution of the excess power produced by the viagra drug turbine, and the occasional reliance on tramadol no rx overnight cod the grid for backup power are far better use of materials and resources than what would be required in order to have on-site storage needed to operate entirely off the grid.

Radar Absorbing Turbines Prevent Aircraft Confusion

The U.S. Military has recently expressed concern about Maryland offshore wind projects because radar could identify spinning turbine blades as low-flying aircraft, potentially disrupting its training missions in the area.  Turns out the UK Military is blocking wind projects for similar reasons.  If only there were a cool, high-tech solution to this?

Turbine company Vestas and technology consultants QinetiQ have developed what they're calling Stealth Turbine technology - a way to hide turbines from radar by using radar absorbing materials in their construction.  During a test project using the materials on a Vestas V90 turbine, radar measurements were taken and the turbine's radar signature was drastically reduced.  The small remaining signature would easily be eliminated by air traffic and air defense computers as insignificant.

If these invisible turbines were deployed, the UK's Department of Energy & Climate Change beileves 5 GW worth of blocked wind projects could be given the go ahead.  Just in case the which is better viagra cialis technology doesn't make it out of the test phase, researchers in the UK are also working on updating the main air navigation system to differentiate between turbines and low-flying planes.

203 MW Wind Farm Completed in Utah

It's great to see some of the large wind farm projects that were just ideas a couple of years ago become reality. First Wind's Milford Wind Corridor project has just seen the completion of its first phase - 203.5 MW in Millard and Beaver Counties in Utah, the largest renewable energy facility in the state.

The wind farm consists of 97 turbines and will be able power 45,000 homes.  Southern California Public Power Authority is purchasing all of the electricity generated over the next 20 years on behalf of the cities of Los Angeles, Pasadena and Burbank.

Construction on the wind farm began almost exactly a year ago.  Over the next few years, the wind corridor will expand to include four more phases totaling over 1 GW of wind energy capacity.

Wind Turbines to Power Cell Phone Towers

Small-scale wind turbines can't produce the large amounts of power that their giant brothers can, but there's still room for them in the renewable energy landscape.  As an example, cell phone company Core Communications will begin using small vertical-axis wind turbines to scam natural viagra power their cell phone towers.

The company will use turbines from Helix Wind that can generate electricity in winds as slow as 10 mph.  The turbines will power the towers and any extra electricity will be sold to the grid, giving Core Communications a new source of revenue as well.

The turbines will be installed on a trial basis on cell phone towers in Southern California for three months starting in early 2010.  If they perform well enough, additional turbines could be rolled out permanently.
