News from the Microsoft Futurists: A Cool Montage and Video of Visions of Clean Technology in 2019

Microsoft presents it’s vision of the year 2019, and I’m so pleased to see some thinking on the green tech side, as I’ve tried to capture in the screen-stills below. Ten years is not too far out, and some of these ideas are fun. For example:

* Connected classrooms where learners share a lesson in natural systems
* Smart home energy monitoring
* Better ecological awareness (through cataloging and intuitive access)
* Urban green roofs

New Generation of Intel Devices Can Measure Air Pollution, “Scavenge” Energy from the Environment

Intel has unveiled a new generation of tiny sensors that continuously analyze air quality in an effort to further understand and combat air pollution. The corporation also announced on Friday that it is developing devices that can tap energy from sunlight, body heat and television signals.

Asthma Inhalers Scheduled to Go Green, Become More Expensive

inhaler

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.

Traffic Pollution Sensors Getting a Trial Run in the UK

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 Progressing Toward 3,000 MW of Emission-Free Nuclear Power in Texas

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)

Medieval Churches: Solar-Powered Nanotech Pioneers

stained glass

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.

Dutch Town Paving Street With Air-Purifying Concrete

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.

Beijing Smog Reduction for Olympics Demands Widespread Sacrifice

china olympics

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 »

Nuclear Power Plant Construction License Application Making Progress in Maryland

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.

Units 1 and 2 of Calvert CliffsThe 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.

Trucks Reduce Emissions by 83%

truck fuel effiencyTruck 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.
