Gas 2.0

The United States Postal service is the second largest civilian employer in the country, after Wal-Mart. Over 650,000 are employed by the USPS, which utilizes some 260,000 vehicles. While 43,000 of these vehicles run on E85 fuel, they still manage to get an average of just 9 mpg. Pretty terrible gas mileage, and E85 made with today’s methods isn’t all that much better when it comes to carbon emissions anyway.

Perhaps that is why the government is considering granting the USPS $2 billion to electrify 20,000 delivery vehicles. And if there is any government agency that could benefit from electric vehicles, it is definitely the USPS.

If you’re going to deliver half the world’s mail, you might as well do it with fuel-efficient vehicles, and, of course, deliver it on foot in as many communities around the country as you can.

While stymied by financial losses ($3.8 billion in 2008), the US Postal Service continues to commit resources and practice innovation when it comes to adopting fuel efficient delivery vehicles. After all, they had an all-electric delivery vehicle on the road – in 1899 (manufactured by the Winton Company).

Today, three-wheel electric vehicles, called T3s (seen to the left), are being tested as possible replacements for traditional gasoline delivery vehicles in Florida, California, Texas and Arizona. The T3 has a range of 40 miles, a maximum speed of 12 mph and a load capacity of 450 pounds. Powered by two rechargeable modules, the T3 has zero tailpipe emissions and costs 4 cents a mile to operate.

Pretty much everything in America, at some point (and often multiple points) hitches a ride on a tractor trailer of some sort. It doesn’t matter if it is locally grown organic produce or the latest and greatest Chinese-built computer. By the time it has arrived at your home, it’s probably been on one of these big, smelly beasts.

Improving the fuel efficiency of tractor trailers would be a big deal not just for the environment, but for our wallets as well. So we can all celebrate the latest round of funding from the Department of Energy that is going towards improving the efficiency of Class 8 trucks by 50%.

The tapering tail is no secret among scientists for improving stability and fuel efficiency. Many high-mileage concept cars feature just such a design to smooth the aerodynamics of the vehicle. Now imagine applying the same concept to container trucks that log more miles in a year than most of us travel in five.

A Dutch public-private enterprise did just that, adding a 6 foot long tail to the end of a tractor trailer truck. The results from two years of testing were a 7.5% increase in fuel efficiency, and thus a similar decrease in emissions.

Trucking is among the most important, yet polluting parts of our environment. Everything everywhere was delivered by a truck, unless you live on a farm. A necessary evil, if you will. Getting truckers on board with the green movement will play an integral part in the widespread acceptance of alternative fuel vehicles. To do that, you’ve got to hit them in the wallet.

Towards that end, last week Vision Industries, with the help of California Governor Arnold Schwarzenegger, unveiled a short haul, hydrogen-powered truck dubbed the Tyrano.

Indiana-based Bright Automotive has released some pretty impressive performance figures for its technically (and aerodynamically!) slick new IDEA cargo van. Aimed primarily at delivery fleets and in-town rental companies, the freshly-upgraded guppy promises to shave operating costs by thousands of dollars per year, per van.

More pictures, an official company press release, and my own opinions (that nobody asked for) after the jump.

California has ruled that all ocean-going vessels within 24 nautical miles of California’s coastline must now use cleaner burning diesel fuel; which by 2012 will have have reduced sulphur emissions by 95%.

Researchers writing in the journal Environmental Science and Technology have concluded that unless new low-sulfur standards are adopted for the ubiquitous marine fuels used worldwide to get that Barbie from China to your doorstep, 40,000 needless premature human deaths may occur each year due to the harmful emissions caused by high sulfur fuels.

The Auriga Leader, a Japanese owned NYK cargo ship capable of carrying 6,400 cars and using over 300 solar panels as part of its power supply was docked in Long Beach yesterday, and just departed. It is the first commerical cargo ship employing solar power technology to reduce diesel emissions. The solar panels can supply up to 15% of the vessel’s electrical power when docked. The ship will probably return to Long Beach in about 30 days, and could be available for visitation. Call the Port of Long Beach to find out specific details about the possibility of seeing the solar panels. The ship is in the service of Toyota, carrying its’ vehicles from Japan.

At 665 feet long, and about 100 feet deep and wide it has a carrying capacity of 60,000 gross tons.  1.6 million dollars was the cost of the solar technology – to install and make it operational. The Auriga is the first in a generation of new cargo ships which will use solar power to reduce their diesel consumption. Emissions from cargo ships are a globally massive source of air pollutants…” just 15 of the world’s biggest ships may now emit as much pollution as all the world’s 760m cars” according to a recent publication. Shipping pollution has been found by research to contribute to human deaths.

The Long Beach port is one of the busiest in the nation, and is a very large air polluter due to the activities of large ships and approximately 100,000 diesel trucks. The Long Beach and Los Angeles ports may be the number one polluter in the state of California. A special report was produced on the problem by California Connected.

Solar technology used by the Auriga Leader is a small attempt to start reducing emissions from cargo ships. Lessons learned from the Auriga can be utilized for solar technologies on other vessels, which will need to start going green if there is to be any reduction in air pollution and carbon emissions. NYK engineers are considering similar solar power installations for their 800 other ships.

The Port of Long Beach has been making efforts to reduce air pollution and was commended recently with an EPA Green Flag for trying to slow cargo vessels as they motor towards the docks, in order to reduce their emissions.
