Axion International Holdings has won a $957,000 contract to provide the U.S. Army with two bridges made from a thermoplastic composite and recycled plastic, the company announced Wednesday evening.

The two bridges, which are replacing old wooden ones, will be constructed at Fort Eustis in Virginia from a proprietary Recycled Structural Composite (RSC) developed by Axion in conjunction with scientists at Rutgers University.

The railroad cross-ties will be made entirely of a plastic composed of recycled materials from both consumer and industrial plastic waste. Axion asserts that its recycled plastic railroad ties are actually longer-lasting that typical creosote-treated wood railroad ties.

Both the 40-foot and 80-foot bridges to be built will each have a high-loading rating of 130 tons, and be used to transport both locomotives and freight traffic, according to Axion.

The location is significant. Fort Eustis is home to the U.S. Army Transportation Corps, the branch of the Army responsible for coordinating the movement of personnel and cargo. The Fort Eustis motto is Einstein's famous quote "Nothing happens, until something moves." It's also the location of the U.S. Army Transportation Museum.

But this is not the first military bridge to be made out of plastic by Axion for the military. The Army has previously built plastic bridges for Fort Bragg and Camp Mackall in North Carolina using materials and structural design that allowed for a bearing load of 73 tons for tracked vehicles and 88 tons for cars and trucks. To demonstrate its strength a 70-ton M1A1 Abrams tank was driven across the bridge at its official unveiling in September.

The design and engineering of the bridges is being be done by Parsons Brinckerhoff and Centennial Contractors Enterprises.

Lithium-ion battery manufacturer EnerDel has signed an 18-month, $1.29 million contract with the U.S. Army to design and test hybrid battery options for the Humvee.

Trying to power the iconic fuel-guzzling High Mobility Multipurpose Wheeled Vehicle (HMMWV aka Humvee) with a battery, may seem like trying to put out a fire with a garden hose. But a lithium-ion battery system can deliver a lot of power from a battery quickly, giving a truck like the Humvee the thrust it requires.

EnerDel, a subsidiary of Ener1, will collaborate with the U.S. Army's Tank Automotive Research, Development, and Engineering Center (TARDEC) on four possible power systems that could be implemented in the XM1124 version of the Humvee.

The company, which specializes in battery cell chemistry as well as the electronics and battery system designs, said it already has two viable options. EnerDel has developed a lithium-tatinate system in conjunction with Argonne National Laboratory that could accommodate the acceleration and hard braking required for such a powerful vehicle like the Humvee. It also has a lithium-manganese system that would give a vehicle extra-long range and allow electronics to be run off the battery for extended periods of time before needing to be recharged.

As part of the 18-month contract, EnerDel will also be involved in testing the systems under "extreme performance simulations." In addition to putting the test vehicles through the usual Humvee paces of wading through water and mountain climbing, there will also be an endurance test.

That will include seeing how a hybrid Humvee fares as a power plant for a field hospital or temporary military post. The requirement makes perfect sense given the ease with which a Humvee can be transported to hard-to-reach areas. One of its key features has always been that it could be dropped in to virtually any terrain by parachute.

The hybrid Humvee will also be more stealthy. Anyone who's had a close call with a Prius knows how dangerously silent hybrids can be in total battery mode. The hybrid version of the Humvee will have a powered-down "silent watch" mode that will allow it to run with its diesel generator off, reducing not only its noise, but also its thermal signature to avoid detection.

As always with major military project announcements, the company involved was quick to point out the down-the-road commercial application of its technology.

"In keeping with a long tradition, we also expect that innovations perfected here will have important benefits for the commercial markets," EnerDel President Rick Stanley said in a a statement.

There has already been interest in Raser Technologies' H3E, a plug-in hybrid version of a Hummer-branded SUV called the H3. While not truly a Hummer (the civilian version of the Humvee), the "Hummer-light" descendant has garnered the interest of even the most discerning Hummer enthusiasts.

So if EnerDel's batteries might be good enough to power a Hummvee, why haven't commercial automakers been knocking? They have actually. The company has signed research partnerships of varying commitment levels with Think Global, Fisker Automotive, Volvo, and Nissan. Its parent company, Ener1, is also working with U.S. utilities to develop smart grid storage units.

Trash collection giant Waste Management and the Linde Group petroleum engineering firm have partnered to create a plant that makes liquefied natural gas (LNG) from landfill gas, both companies announced this week.

Linde designed and operates the plant which is located close to Waste Management's Altamont Landfill near Livermore, Calif.

"The opening of the world's largest landfill-gas-to-LNG plant right here in California is a milestone and a testament to our commitment to reduce greenhouse gas emissions. Now that the technology has been proven, we look forward to seeing its adoption spread so more vehicles can run on garbage," Linda Adams, secretary of the California Environmental Protection Agency, said in a statement.

Contrary to what might be inferred from Adams' enthusiastic sound bite, the project is not the utopistic dream of incinerating any old trash in a DeLorean for fuel, nor has either company claimed this. What the project does show is an idea that reduces pollution in two ways. The renewable source for fuel is also a naturally occurring gas that would have otherwise released itself into the atmosphere.

Waste Management collects the gas that is produced from the naturally occurring decomposition of organic trash in its Livermore landfill. The Linde plant then purifies and processes that gas into LNG. The LNG is then used to fuel some of Waste Management's fleet for collecting trash and recycling. Those vehicles, of course, having been slightly modified so that they can run on LNG.

While the plant has only produced about 200,000 gallons since it started operating in September, it has the capacity to eventually produce 13,000 gallons a day or 4 million gallons a year. That would be enough to cover the fuel needs of 300 Waste Management vehicles used for garbage and recycling collection, and save about 30,000 tons of emissions per year, according to company statistics.

This is not the municipal collection giant's first foray into trash-to-energy tech. Waste Management has been distributing solar-powered trash compactors and investing in various projects geared at converting waste in usable energy in several different forms.

Fuel efficiency is the No. 1 factor in equipment purchases within the trucking industry, a new report from IBM says.

At the same time, brand name has fallen to the bottom of the criteria list and "faces the risk of slow death," according to the report.

The combination of those two factors means that new players in the trucking industry will give established brands a run for their money.

"The truck ecosystem will thrive because of--rather than in spite of--a chaotic introduction of new players," the report said.

"Truck 2020: Transcending Turbulence," which came out of IBM's Institute for Business Value, was based on interviews of 91 executives from 13 countries and from across the industry, including truck and bus original equipment manufacturers (OEMs), suppliers, regulators, and industry associations.

The trucking industry has been faced with financial hurdles, higher energy costs, and the image as a polluter in recent years, according to IBM. And the necessary advances for the industry are not restricted to strides in fuel efficiency.

Telematics will also be key, the report said. Evaluating and diagnosing vehicles remotely and in real time will be a useful tool in preventative maintenance. It will cut down on unexpected breakdowns that disrupt service and that cost trucking companies time and money, according to the report. Telematics tools that collect real-time data can also be useful for curbing litigation over accidents, the report noted.

While the growing significance of telematics may be entirely true, it should be noted that IBM has a vested interest in that field.

Big Blue has said it sees automotive computing as the company's next frontier and has been actively developing telematics and infrastructure technology for at least the last six years.

As far back as 2003, IBM began developing XML-based data retrieval architecture that would allow vehicles to receive real-time traffic and speed data from highways. In 2005, it signed a $125 million telematics deal with United Arab Emirates. And in 2006, it began partnering with manufacturer Magna Electronics to develop smart car parts.

American start-up Fisker Automotive may be about to unveil the first truly affordable plug-in hybrid for the U.S. market.

Ray Lane, managing partner at Kleiner Perkins Caufield & Byers, told an audience at the Always On Going Green conference in Sausalito, Calif., on Tuesday that there could be a big announcement within the next week about a $39,000 plug-in hybrid. Though he would not say who, he mentioned that it was a car for the U.S. market and that it was not strictly electric, according to a report from Cleantech Group.

While Kleiner Perkins has investments in several transportation start-ups such as Think Global and EEStor, the likely company from its repertoire to make such an announcement would be Fisker Automotive.

Fisker has already unveiled the Karma, a four-door luxury plug-in car that can go from 0-62 mph in 6 seconds, and has a maximum speed of 125 mph. But Fisker has set the tentative price for the car at $87,900, making it not much cheaper than Tesla's Roadster sports car.

Fisker CEO Henrik Fisker also told CNET in an exclusive May 2008 interview that advances in battery and software technology would allow his company to offer a $40,000 plug-in car in about four or five years.

Perhaps that day has come sooner than the founder was willing to let on at the time.

But it may not be as soon as others have speculated. Fisker's European press office sent out an e-mail on Monday informing journalists the company has canceled a press conference originally scheduled for this week at the 2009 Frankfurt auto show.

The Republic of Maldives has signed a partnership with a tech company to develop biochar for its soils, both parties announced this week.

Biochar, a method of carbon capture and storage, is typically produced by heating biomass in a kiln until it turns into a manmade charcoal. That biochar can then be buried to enrich soil for agriculture. In some cases, biochar can be used as fuel.

The deal with U.K.-based Carbon Gold is part of the Maldives' plans to be carbon-neutral by 2020.

With the help of Carbon Gold, the Maldives will manufacture biochar from woody biomass, including coconut shells, for use in its own soil. As part of the deal, Carbon Gold will also launch an informational campaign directed at Maldivians on the benefits of using biochar rather than imported fertilizers to enhance soil quality for agriculture.

"The Maldives is already adversely affected by climate change so I warmly welcome this relationship with Carbon Gold. Biochar has a crucial role in helping us achieve carbon neutral status as well as providing an economic and environmental boost to our people," Maldivian President Mohamed Nasheed said in a statement.

Though not a very powerful player on the global carbon stage, the Republic of Maldives is significant for being at the front line of climate change. If the Earth warms and seas rise as predicted, scientists believe the Indian Ocean archipelago country will be the first to go under water.

Raser's Hummer H3E gets 35 mpg, 100 mpg, or 190 mpg in city. It depends on how you calculate mileage.

The plug-in hybrid Hummer H3E by Raser Technologies actually gets better mileage than originally estimated.

At the SAE World Congress and again at a Hummer event hosted by California Gov. Arnold Schwarzenegger, Raser originally said (based on a prototype) its E-REV power train could give the Hummer an initial range of 40 miles on electricity only. After that first 40 miles, the SUV would then get about 33 to 35 mpg earning it the dubious moniker of a Hummer that gets over 100 mpg.

Raser's power train is an electric motor-drive system powered by lithium ion batteries, and a gas-powered generator, aka "range extender," to recharge the batteries.

But further street testing has shown the power train's engineers that the H3E could actually get by on its electric battery alone for the first 50 miles using 60 percent of the battery pack, according to statistics released by Raser.

"This initial test indicates that the vehicle should easily achieve over 100 miles per gallon in typical local daily driving," Jim Spellman, Raser's vice president of business development, said in a statement.

Note Spellman's word choice of "typical local daily driving."

While the U.S. military has several incarnations of airplane drones running on various alternative fuel sources, it's not something the average person, or even company, can go out and buy.

That might be changing.

BlueBird Aero Systems and Horizon Fuel Cell Technologies announced Thursday that they've co-developed the Boomerang, the "world's first commercial fuel cell Unmanned Aerial System (UAS)."

So far the Boomerang only seems to have flight approval for Israel, but it's about to be unveiled next week at the Association for Unmanned Vehicle Systems International conference in Washington, D.C., which could garner it significantly more attention and interest.

The plane contains a 2kg hydrogen fuel cell power pack called the Aeropak made by Horizon Fuel Cell Technologies. The company claims it can provide 900Wh (Watt-hours) of power allowing the Boomerang to fly for over nine hours straight. In addition to supporting flight, the power pack can also support ancillary devices like electro-optical sensors, infrared cameras, and laser designators.

Horizon Fuel Cell Technologies is the same company that developed the power packs for the Hyfish fuel cell-powered "flying car" as well as a wide assortment of fuel cells for remote control cars and educational products.

This might be the first print ad ever for a fuel cell-powered UAS.

It looks like those unsightly utility poles throughout New Jersey will be getting yet another accessory.

The New Jersey Board of Public Utilities is set to approve on Thursday a $200 million contract between Public Service Electric and Gas (PSE&G) and Petra Solar to install over 200,000 photovoltaic panels to tie in to the state's electrical grid.

Petra's SunWave solar panels, which have smart grid communication tools built-in, will be attached to utility and light poles that are owned and operated by PSE&G throughout the state.

The project to develop, install, and maintain the grid-connected solar system will create about 100 green jobs, according to both Petra and PSE&G.

"We are tripling in size and will start hiring immediately," Petra CEO Shihab Kuran said in a statement.

The installation is part of an initiative that PSE&G announced in February 2009 to bring solar panels to every town in its New Jersey coverage area.

The Petra Solar installation will be the "largest pole-attached solar installation in the world," according to PSE&G. But it's only part of the $515 million in 80 megawatts worth of solar energy projects that the New Jersey utility is expected to get approval for on Thursday.

PSE&G plans to implement solar installations on the rooftops of its offices and facilities throughout the state, as well as "solar gardens" on some of its properties. It was also approved to develop an additional 5 megawatts worth of solar power in New Jersey urban enterprise zones within its service area, and 10 megawatts in conjunction with third-parties wishing to participate in an installation on their properties.

"Our program will effectively double the size of New Jersey's installed solar capacity. That is more solar capacity than currently exists in any state other than California," Ralph LaRossa, PSE&G's president and COO, said in a statement.

LaRossa is referring to California's giant solar installation approved in February 2009, for the utility Pacific Gas & Electric to produce 500 megawatts worth of solar energy from distributed solar panels throughout the state.
