TMCnet Green Tech Week in Review

- Alert), the testing established that f the fuel cells have durability, longevity, and reliability in extreme climate conditions. Completion of the trials is expected in June of this year, in accordance with VelaTel's projected timeline. These trials mark a significant milestone, as they will allow for future sales of hydrogen fuel cell systems to Chinese telecommunications carriers—some of which include VelaTel's joint venture projects. Success with Chinese telecommunications carriers is then likely to lead to sales of the hydrogen fuel cell systems internationally.

In its “State of the Air” report for 2012, the American Lung Association reveals that the air quality in America’s most-polluted cities is at its cleanest since the ALA began issuing its research 13 years ago. Standards set under the federal Clean Air Act have required states to take a number of steps to clean up major air pollution sources —coal-fired power plants, diesel engines and SUVs —and the legislation has worked, cutting ozone (smog) and particle pollution (soot) from the air in urban areas. The news wasn’t all good, however. Despite this progress, the ALA said that unhealthy levels of air pollution still exist and in some parts of the country have worsened; and that than 40 percent of people in the U.S. still live in areas where air pollution continues to threaten their health.

And finally, it looks like a UFO, but it’s actually a prototype of an airborne wind turbine designed to drift aloft at high altitudes. Once launched, it catches stronger gusts than, and generates twice the power of, a conventionally tower-mounted diesel model, at a lower price. Boston-based Altaeros Energies recently completed testing of a 35-foot scale prototype of the Altaeros Airborne Wind Turbine (AWT) at the Loring Commerce Center in Limestone, Maine. The prototype, fabricated in partnership with Doyle Sailmakers of Salem, Mass., achieved several key milestones—among them, climbing 350 feet high and producing power at high altitude Altaeros is developing its first product to reduce energy costs by up to 65 percent by harnessing the stronger winds found over 1,000 feet high and reducing installation time from weeks to days. The AWT (News - Alert) also is designed to have virtually no environmental or noise impact, and to require minimal maintenance.  The firm currently is seeking partners to join its effort to launch the first commercially available high-altitude wind turbine in the world.
