Before taking to the road, Cece Reinhardt and Brenda Daugherty designed the traveler’s toolkit they needed, retrofitting a 2003 Airstream Safari with a number of eco-friendly materials and then converting their used diesel truck to run on waste vegetable oil (WVO)

Solar powered military installations are nothing new but there is a twist to the solar arrays being installed at Los Angeles Air Force Base, because LA AFB is also booting out its old gas guzzling general purpose vehicles in favor of a fleet of electric vehicles, making it the first federal facility of any kind to replace an entire fleet with EV's

If it’s little and cute, chances are it’s either made in Japan or will soon be available there. This ultra-compact 3-wheeled and currently nameless electric scooter announced by Kyoto’s first venture company, Green Lord Motors, is both

Alternative transportation fuels have been heralded as a way to shift heavy-duty trucks away from diesel or gasoline toward cleaner burning fuel, but the transition has remained a road too far for one main reason – lack of infrastructure.
Even though gasoline prices are high and reducing pollution is an imperative to environmentalists, it’s still easy to find a gas station whenever you need one. The nationwide network of filling stations has been built over the past 100 years, giving oil-based fuels an advantage over newer alternatives, like hydrogen or natural gas.
energyNOW! correspondent Lee Patrick Sullivan traveled to California to learn about efforts to build a new network of alternative fuel filling stations – the Interstate Clean Transportation Corridor (ICTC)

Specialized challenges are usually pretty entertaining – wacky ideas come to life to compete, and often garner some pretty impressive results. The upcoming World Solar Challenge in Australia should deliver some fun; competitors must drive from Darwin to Adelaide, a total of 1,864 miles across the desert, without using any fossil fuel

Today's fishwrap is tomorrow's biofuel: a research team from Tulane University has found a low cost, energy efficient way to recycle ordinary newspaper into butanol biofuel, which can be used as a drop-in replacement for gasoline. The secret ingredient is a bacteria found in animal droppings, which naturally produces butanol as it digests the news.

So, below are some top cleantech stories of the week we haven't hit yet. But before you check those out, I want to let you know that I'm changing the way I do these daily/weekly news roundups (again). I think this new change will be best for everyone (hope so)

As we search for a battery technology that will answer our aspirations for energy storage, Eos rechargable Zinc-Air battery may be the chemistry that can provide sufficient energy density

It's not uncommon to see incentives for buying an electric car, but owning one is another matter entirely.
Electric cars have many qualities making them attractive as urban commuter vehicles – particularly when driving through heavy traffic. The question of how an EV does on a longer road trip is one that does not as of yet have a definitive answer. France, for example, is installing charging stations on its highways, but that project isn’t finished

Across much of the globe, bicycles are the most popular form of transportation. In fact, some estimates say about twice as many bikes as cars are on the world’s roads, and a growing number of these bikes, around 120 million, are electric. Bicycles may be the most popular form of transportation in countries like China or Denmark, but that’s not yet the case in America – we love our cars.
However, high gasoline prices and environmental concerns could combine with new technology to make e-bikes the future of two-wheeled transportation in the U.S. energyNOW! correspondent Josh Zepps met one of the world’s top e-bike experts, an e-bike retailer, and a family of commuters who wouldn’t want to travel any other way

Fleet owners and consumers need to know if an electric vehicle will provide sufficient range with their present driving habits. The EV Profiler is a sensor that is plugged into your vehicle and a system that can provide hard data. Fleet owners and consumers may find this kind of hard data reassuring.

Tokyo Tower has been crushed by Godzilla more times than I can count. Its presence silently locates any scene in Tokyo. While not always visible in the midst of a skyline filled with high-rises and skyscrapers, its orange and white figure is instantly recognizable. Built as a broadcast station in 1958, it is illuminated every night and broadcasts television and radio (analog and digital)

In a twist on the old set a thief to catch a thief ploy, researchers at Michigan Technological University have found that a copper-loving bacteria can help corn suck copper contamination out of soil. The discovery could help clean up highly contaminated abandoned mining sites that have resisted other forms of "green" remediation

Solar roads have been a dream of countless cleantech lovers for awhile now. And there's actually a company with the name Solar Roadways. We've written about the potential of solar roads and solar bike lanes a number of times over the years, but there's news out now that Solar Roadways has received a $750,000 grant from the Federal Highway Administration to build a parking lot in Idaho paved with solar panels, the most practical application of the idea I've heard of in the

A new Air Products hydrogen fueling plant at the Orange County Sanitation District wastewater facility in Fountain Valley, California is producing clean, renewable electricity and hydrogen fuel and heat for use on-site and in hydrogen fuel cell vehicles. The wastewater-biogas-power-and-fuel plant could open up significant opportunities to use similar designs and technology to manage water and process agricultural, food and brewery waste streams.

Electric cars have giant batteries (useful for a number of things besides driving the actual car, even). Also under consideration as the primary power source for electric cars (and buses, motorcycles, yachts, etc.) is the lithium ion capacitor
