Come December 31, all albuterol inhalers in the U.S. will be a little bit greener— and a lot more expensive. The inhalers will stop using chlorofluorocarbons (CFCs) that damage the ozone layer, and will be powered by hydroflueroalkane (HFC) instead. While the new inhalers will benefit the environment, they will also cost $30 to $60. CFC inhalers cost only $5 to $10.

Have you ever wondered how many pollutants you’re breathing in while sitting in traffic sandwiched between two trucks? The Mobile Environmental Sensing System Across a Grid Environment (MESSAGE) can tell you. The system, designed by researchers at Newcastle University, produces real-time data on traffic pollutants including carbon dioxide, nitrogen dioxide, and noise.

Exelon, the largest operator of nuclear power plants in the United States has filed a license application with the US Nuclear Regulatory Commission (US-NRC) to build two new nuclear power plants near Victoria, Texas. When operating, the plants will produce zero units of carbon dioxide, nitrogen oxides, mercury, sulfur oxides, and fly ash.

Exelon has chosen the Economic Simplified Boiling Water Reactor (ESBWR) marketed by GE-Hitachi Nuclear Energy. Each of the reactors will produce approximately 1,500 MW of electric power.

One of the key design features of the ESBWR is a large degree of passive safety provided by large water reservoirs, natural coolant circulation and safety systems that operate without any electrical power. (Link to animation of ESBWR safety system operation)

As I recently discussed, sometimes we need to look to the past for solutions to our current problems. Queensland University professor Zhu Huai Yong has done just that, noting that painting glass windows with gold particles can purify the air.

Zhu came across this realization after studying medieval painted church windows, which were often decorated using glass colored with gold nanoparticles.

Though people likely did not realize it at the time the churches were built, the sun-energized nanoparticles destroy air-borne pollutants, as sunlight creates an electromagnetic field that resonates with the gold particles’ oscillations.

Now here’s an innovation that might make me consider moving back to New York City: air-purifying concrete. The small Dutch town of Hengelo is testing out the concrete paving stones, which contain a titanium-dioxide based additive that binds to nitrogen particles emitted by car exhaust and turns them into harmless nitrates.

As the date for the 2008 Games rapidly approaches, Beijing struggles to improve air quality for the “green games.” By closing factories, limiting vehicle use, and halting all construction projects, Chinese authorities are trying to make last-minute improvements that rely on wide-spread compliance. Athletic performance, health, and China’s reputation could suffer if the smog doesn’t clear.

China has implemented a variety of emergency measures to tame the haze, which will have a significant impact on all levels of society. Personal vehicle use is limited from July 20 to September 20. Drivers in Beijing can only drive on alternating days and high emissions vehicles are banned completely. Meanwhile, mass transit is being expanded and work hours staggered to help ease transportation woes. Read the rest of this entry »

It has been darned hot on the East Coast, and the electric companies have been asking their customers to conserve power whenever possible, especially in the heat of the day. Each day this week one of the topics of conversation in my carpool has been the oppressive heat and poor air quality.

The power conservation warnings and the “Code Red” air quality alerts made me think about last week’s announcement by Unistar Nuclear, a partnership between Constellation Energy, Areva, Bechtel, and EDF, that they had successfully filed their combined Construction and Operating License (COL) application for a third unit at Calvert Cliffs.

The plant is not exactly in my backyard, but it is only about an hour’s drive south of my home. Though watching and waiting for the Nuclear Regulatory Commission (NRC) to issue a new nuclear plant license to allow the beginning of construction can be a bit like watching grass grow, the decision to “docket” the application indicates that real progress continues.

If you want to read an article that provides an indication of how the idea of the plant plays to local politicians I recommend a visit to a Washington Post article titled Coalition Formed to Advocate For New Power Plants, Lines.

Truck stop electrification is boosting fuel efficiency and minimizing dependence on foreign oil from idling trucks

There are 1.3 million long-haul diesel trucks with sleeper cabs in the United States, with most drivers averaging over 100,000 miles annually. These trucks are highly affected by skyrocketing fuel prices and are dependent on foreign oil. As the value of the dollar diminishes, transportation costs are partly to blame.

Idling Trucks Waste Fuel

Truck drivers are required to rest for 10 hours for every 11 hours of driving. A large amount of fuel is consumed when drivers leave trucks idling to maintain comfort. 85% of the energy is wasted sleeper cabs are heated by an idling truck. It is even more inefficient to cool the sleeper cab, wasting 94% of the fuel’s energy.

300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.

This facility at Waste Management’s (WMI: NYSE) Altamont Landfill in Livermore, California will begin operation in 2009. It comes with a price tag of $15.5 million, with grants providing $1.4 million.

Cleaner Fuel

Waste Management is the largest waste management company in North America and operates the largest US fleet of heavy-duty collection trucks. The company has a goal to reduce fleet emissions by 15% by 2020. Read the rest of this entry »

The average Chicagoan spends an hour and a half commuting to and from work each day. With the second largest public transportation system in the country, one million people ride city buses each day. Mayor Daley considered both facts when he devised a plan aimed at easing congestion, commuting times, and air pollution in the central business district. A $153 million federal grant can help make this plan a reality.

Priority Given to Buses Over Cars

The first part of the plan entails creating a 100 mile bus corridor with dedicated bus lanes during peak hours. Kiosks selling bus tickets allow passengers to quickly board buses and many routes will run express, resulting in fewer stops. Traffic lights will be programmed to turn green for buses, helping to keep them in motion. Hybrid buses will be used, reducing pollution in these heavily populated areas.
