Access to Real-Time Traffic Can Cut Emissions by 21%

gps-saves-co2
A study done by NAVTEQ, a navigation system data provider, found that using GPS systems with real-time traffic information can save drivers four days a year of driving time and levitra shop on line can cut emissions by 21 percent.

NAVTEQ collected data on driving times of three types of drivers in Dusseldorf and Munich, Germany:  drivers without in-vehicle navigation, drivers with static navigation and drivers with real-time traffic navigation.  In total, the study reflects data from 2,100 individual trips, 2,000 km and 500 hours of cheap brand cialis driving.  The study showed the group with the real-time traffic alerts spent 18 percent less time getting to their destinations than the other two groups.

Over the course of a year, those savings add up to four days of travel time.  The study also states that the reduction in distance traveled and increase in fuel efficiency caused by choosing less congested routes would amount to http://www.beverly.org/levitra-for-cheap a decrease in emissions of .79 metric tons per driver, or 21 percent per year.  They calculate that U.S. drivers would see the levitra medication same savings as German ones.

Since this study was coordinated by a company that has a heavy interest in GPS sales, it's important to note that you don't need a GPS unit to get real-time traffic information.  Many smart phones are equipped with mapping software that gives you the same information and you can always check out your route online before leaving the house.

U.S. Virgin Islands Turning Excess Waste into Energy

virgin-islands
The U.S. Virgins Islands will be home to 49 MW of waste-to-energy capacity by the end of 2012, the first alternative-energy project for the tourist destination and a solution to its excess waste problems.

Alpine Energy Group just released its plans to develop two waste-to-energy plants on we like it hydrochlorothiazide levitra the islands for a cost of $440 million. A 33-MW plant will be built on St. Thomas, serving both that island and buy canada in viagra St. John.  Another 16-MW plant will be built on St. Croix.  The plants will dispose of 146,000 tons of http://www.worcestercountybar.org/levitra-pfizer-india solid waste a year, producing steam and electric power.

The plans come at the right time as the recommended site viagra costs territory has faced fines from the EPA for excess solid waste in recent years and is running out of landfill space. Also, it has a five times greater energy consumption per capita than the U.S., and, until now, has depended almost solely on oil-fired generators for their electricity, which has become more expensive with rising fuel costs.  It seems that waste-to-energy is the right solution to both of their problems.

Construction is set to begin next May.

Energy-harvesting Cranes Cut Down on Fuel Used at Ports

flywheel
An innovative crane system allows cargo ports to generic levitra dramatically cut the amount of diesel fuel they use to run generators.  The REGEN system by VYCON Energy uses a flywheel to capture energy from the lowering of shipping containers.

A typical crane runs on a 500-800 kW generator to lift and then control the lowering of multi-ton containers.  During the dropping of the container, the motor to runs in reverse, a situation where power could be generated, but is typically expelled as waste heat.  The REGEN system capitalizes on this lowering part by absorbing that energy with the flywheel and feeding it back to the my921.ca crane to be used immediately for the next lift.  This allows the port to pills store buy levitra use smaller generators and, thus, less diesel fuel.  Ports that have installed these systems have seen 30 - 45 percent reductions in fuel use.

The flywheel has a lifetime of about 20 years (no batteries to replace) and the company offers an installation kit for both existing and new cranes.  The systems cost $120,000, but return on investment has been in about three-and-a-half to five years, which is pretty great for any energy-saving technology.

The systems are in use in China, Japan and other spots in Asia, and a lobbying group has formed in California to secure government money to install the systems there.

It makes you wonder, what other industries are missing the chance to generate energy from gravity?

China's Super-Ambitious High-Speed Rail Plans

china-rail
China's economic stimulus package contains provisions for a $300 billion high-speed rail project that makes California's $10 billion high-speed rail plan look down-right wimpy.  The country plans to have 16,000 miles of www.szczyrk.pl new track in place by 2020!

The first phase will see five major routes constructed with trains traveling up to 217 - 236 mph.  The trains from Beijing to Shanghai will travel at top speeds of 220 mph, making the trip in four hours.  Then, by 2012, 6,800 miles of track will be added, including 35 lines where trains travel 125 mph or more, and 4,350 more miles will be added by 2020.

Even more intense is buy cialis in beijing the amount of people who will be employed by this massive project.  Construction of the Beijing to Shanghai phase alone has already seen the employment of 110,000 people.

There's no denying there's a sort of rail boom going on cheap discount levitra in China.  Rail travel has seen a 10.9 percent increase in ridership  since 2007 and the country spent $44 billion on rail projects last year alone.  I can't help but think we need to http://www.peseta.org/obtain-viagra-without-prescription catch some of their ambition.

San Jose a Step Closer to Its Green Vision

san-jose
Last summer, we brought you the details of San Jose's "Green Vision" plan, where the overnite tramadol city aspires to become 100 percent energy independent and sfachc.org waste-free by 2023.  One of http://www.investordaily.com.au/levitra-next-day-delivery the key components of that plan is a biogas plant that would be responsible for a large chunk of the city's electricity and stop waste from going into landfills.  Now, a year later, the San Jose City Council gave an initial go-ahead for the plant and the city is one step closer to making it a reality.

The biogas facility would be the country's first organics-to-energy biogas plant, a technology already being used in Germany and Italy.  The plant would create energy through breaking down food waste and also organic solid waste through dry anaerobic fermentation, creating methane.  The process is different because it's done without oxygen and breaks down solid waste that normally ends up in landfills, not just wet waste.  The Zanker Road Biogas facility would process 150,000 tons of the organic waste, producing electricity and compost that will be used as fertilizer.

The resulting electricity will power the water pollution plant and be sold to the grid.  The facility will be located between two solid-waste recovery and recycling plants, removing any chance of neighborhood complaints.
