Spring has sprung and that means summer is right around the corner. If you still haven't worked off those extra winter pounds, it's high time to start before swimsuit and tank top weather cruelly arrives. Luckily, there are new mobile accessories that harness wireless technology, competitive behavior, social media, and other online tools to help couch potatoes catch the exercise bug.… Read more

We're starting to get just a little excited about impending U.S. launch of the Toyobaru twins: the 2013 Subaru BRZ and 2013 Scion FR-S. We've taken more than a few longing looks at each of these cars since their announcement, Subaru's pre-order page is already up, and now (thanks to the EPA's fuel economy web site) we have an idea of what fuel economy you can expect, should you chose to make one of of these vehicles your daily driver.

The Subie and Scion feature identical 2.0-liter, four-cylinder boxer engines that make use of … Read more

Two key players in the hydrogen manufacturing arena will be working together to make hydrogen fueling stations a reality for the fuel cell vehicles that should be coming to market in the second half of this decade.

Air Products and Fuel Cell Energy have signed a Memorandum of Understanding to market stationary Direct Fuel Cell (DFC) power plants. These systems, manufactured by Fuel Cell Energy, are designed to take natural gas or renewable biogas and produce hydrogen, electricity, and heat. The three energy byproducts can be used to power and heat the production facility or nearby homes or businesses while … Read more

To make a statement about its upcoming fuel cell vehicle's zero carbon footprint, Mercedes-Benz decided to cloak an F-Cell to make it seem invisible.

This cloaking technology isn't a new feature that you'll see on the next generation of Mercedes vehicles, even the futuristic hydrogen-powered ones. At least not yet. Engineers pulled off this publicity stunt by covering the F-Cell with LED-embedded mats on one side and outfitting it with cameras on the other. Video captured by the cameras was displayed on the LED mats on the opposite side of the vehicle, which made the car appear … Read more

The burning of fossil fuels and the release of carbon dioxide into the atmosphere don't affect just the air--it also impacts the Earth's oceans, according to U.S. National Oceanic and Atmospheric Administration (NOAA).

Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.

Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more

By building a wind turbine to power a hydrogen production and fueling station, a little hamlet in Long Island is positioning itself as the bellwether for carbon-neutral transportation.

The town of Hempstead, N.Y., on Long Island erected a 121-foot-tall turbine last December on the township's Department of Conservation and Waterways land to take advantage of powerful Atlantic winds and power the hydrogen and natural gas fueling station it built in 2009. The turbine can generate up to 180 megawatts of power per year, and presents an estimated hydrogen fuel and energy cost savings of $40,000 per year. … Read more

DOE researchers are going to the nanoscale to pack more energy into fuel cell vehicles.

Lawrence Berkeley National Lab yesterday detailed research plans for a three-year, $2.1 million Department of Energy-funded project to develop materials that would improve hydrogen storage. The basic research will include technical contributions from the National Institute of Standards and Technology (NIST) and General Motors.

Storage is one of the main technical barriers to hydrogen fuel cell vehicles. Today hydrogen gas is compressed to very high pressures and pumped into onboard tanks, but that method doesn't match the range of gasoline-powered cars. Also, energy … Read more

Startup Oorja Protonics has dodged some of the traditional barriers to fuel cell vehicles, at least with forklifts. In the future, its hybrid approach could be used on cars and trucks, too.

The Fremont, Calif.-based company is in the process of raising funding from corporate partners to ramp up production of its product. The venture-backed company is also profitable, something that few other fuel cell companies can claim.

Rather than use hydrogen as a fuel, Oorja Protonics converts the liquid fuel methanol into electricity in fuel cells. And its onboard fuel cells are designed only to provide a trickle … Read more

I have to hand it to Nike for its unique take on the growing fad of fitness-tracking devices.

The FuelBand is Nike's stab at this segment, which others including the Jawbone Up and Motorola Mobility's MotoActv have already tread. But with production of the Up halted for a battery issue, and Motorola's product still a little-known niche device, there's a big opening in the market.

Unlike some of the other devices, the primary crux of the FuelBand is its Nike Fuel reading, a metric that Nike put together on its own that matches a person's movement through the wristband's accelerometer against data collected on how rapidly oxygen is consumed. As with other fitness monitors that rely on an accelerometer, the readings vary greatly depending on how much you move your arm. Cycling and certain kinds of weight lifting, for instance, wouldn't register much as simply sitting on your couch and waving your hands.

But chances are, if you're spending $149 on a FuelBand, you're going to want to pay attention to the Nike Fuel readout.

Following a press conference that Nike held yesterday to unveil the device, the company took the media on a little field trip to test out the FuelBand in a variety of activities. The following are my early impressions after a day with the device. … Read more
