The SMOG Project by Designer Daan Roosegaarde

After writing about the EPA’s new proposal to reduce greenhouse gas emissions 30% from 2005 levels by 2030, and China’s battle against smog, we want to present a new “Smog-Sucking Electrostatic Vacuum Cleaner” idea that cleanses polluted air:

Copper coils buried in the ground create a positively charged electrostatic field. All particles of ten nanometres or more — including smog — become positively charged, and thus attracted to the grounded earth, where they are collected. “It’s a loop of fresh air,”

The method of ionizing smog particles came from Delft University of Technology researcher Bob Ursem who noticed that tiny particles of organic debris would move from the Atlantic Ocean onto the beach. The particles would fly over the dunes, towards the bushes and then over the bushes. Ursem explained that the particles had a negative charge because of friction and they floated above the negatively charged bushes, “…indicating that the electrical force is greater than the gravity force”. Ursem began studying the negatively charged particles by replicating this phenomenon in his lab and he eventually was able to reverse the charge on the particles using an electrostatic field. Under lab conditions, Ursem created an “ionic wind” as the force of positively charged particles attached themselves to the ground. This sweeping discovery is fascinating also because of Roosegaarde’s awesome plans and creativity. Roosegaarde is trying to build such devices to place on the sides of buildings in Beijing to reduce smog in the city. The latest project specs indicate that the pockets of cleansed air will be in parks so that people can enjoy a 30,000 meters cubed area of fresh air. Another testament to Roosegaarde’s creativity is that he would like the particles in smog that get collected by the air-purifying devices to be turned into “diamond” rings representing the smog that is collected in this process.

America’s Greenhouse Gas News This Year so Far

We at Green Halo Systems have been following the news about the USA’s greenhouse gas policies since the beginning of the year when the Secretary of State John Kerry’s goal was to become the “lead broker of a global climate treaty” according to The New York Times. John Kerry has made President Barack Obama and millions of others focus on global warming in the past six months and today it was announced that the Environmental Protection Agency (EPA) is proposing a 30% cut from 2005 figures to all power plant emissions by 2030.

To review some of what has happened since the beginning of the year, this past February, the EPA drafted a new rule to regulate 1,500 power plans in America to curb climate change and to tighten the language on such a rule. Later that month, Pres Obama ordered the development of new fuel efficiency standards for the nation’s heavy-duty trucks through the use of executive authority. Days later, the Supreme Court considered the President’s orders when it comes to emissions from “stationary sources” such as power plants. Pres Obama’s use of executive authority has since become a popular topic.

At the end of March the Intergovernmental Panel on Climate change report warned that climate change is having a “sweeping effect worldwide” that is likely to grow worse unless greenhouse emissions get under control. The report gave weight to Pres Obama’s effort to use his executive authority under The Clean Air Act.

During April the United Nations report said that the United States needs to develop a climate change law so taxing carbon pollution was up for discussion. Paul Krugman’s response to the Intergovernmental Panel on Climate Change’s statement was that economists’ optimism about limiting emissions of greenhouse gases is due to technological innovations that have decreased the cost of renewable energy.

At the beginning of May, Pres Obama announced investments in energy efficiency and renewable energy. The President campaigned to build support for the EPA’s carbon pollution limits on pollution from coal-fired power plants. Also in May, research about the giant glaciers’ “tipping points” as proof of global warming was scrutinized by The New York Times. Pres Obama also recently stated that the proof of climate change makes this issue “not some distant problem of the future”.

And so now, in the beginning of June, Pres Obama reiterated the importance of climate change policies in his second-term agenda. On June 1^st, 2014, the Obama administration proposed what might be the most ambitious climate change mitigation strategy in the USA so far. The proposal is that the entire power sector (America’s largest carbon polluter) must bring its emission levels down by 30% from what they were in 2005 by the year 2030.

From Motortrends to Jaw Dropping Accomplishments- “Innovation is Expected” at Tesla

Aside from its speed, shocking good looks, ultimate customer satisfaction and impressive mechanical/electrical design there are many fun facts about the innovative Model S. Whatever else the company and Elon Musk have up their sleeve, we are excited to see it in the much anticipated Model X and more!

A reflection on some of the Model S’s impressive accomplishments is in order, and just remember, you read it here.

Some fun facts about the Tesla Model S include:

• The NHTS’s tried to perform a root crush resistance test on the Model S, and it actually broke. The roof crush resistance is over twice the requirement by the NHTSA.
• It also got a 5.4 star crash test rating which was the highest ever recorded.
• The Model S has the largest panoramic sunroof of any production car.
• The Motortrend’s Car of the Year Award is extremely coveted and the Model S was the first electric vehicle to receive this award ever.
• The largest digital display/touchscreen at 17” of any production vehicle. In effect creating a “minimalist” design with no knobs or physical dials on the dash.
• This car also has the lowest drag coefficient of any production car, at 0.24.
• The sound system in the Model S includes “visual surround control” where a 3D image of the insides of the vehicle comes on the screen and users can just drag their fingers to direct music to be louder accordingly.
• The cargo space in the car is the largest in its class, in fact underneath the front hood is even more storage space!
• There are only 20 moving parts
• A web browser is included in the 17” display, with internet provided entirely by Tesla!

Now we are interested in knowing more about Tesla’s commitment to the planet…and that smaller Model S (code name: “Blue Star”).

Adobe-“World Leader in Environmentally Friendly Facilities”

Adobe Systems Inc. which is a digital marketing and digital media company headquartered in San Jose, Ca is very proactive when it comes to sustainability and energy conservation. The company has recognized that their industry is increasingly energy intensive and so they aim to reduce energy consumption and to stabilize their costs. Their ultimate goal is for their buildings to “produce or offset as much energy as they consume, resulting in Net Zero energy usage”. So far, the company has been tracking Scope 1, 2 and 3 carbon emissions (for purchased energy of the leased sites and for employee business travel since these two areas are part of their value chain). Reducing energy demand has been an area of observance for Adobe since before 2002. The company has impressive statistics about their energy efficiency projects and renewable/alternative energy here: http://www.adobe.com/corporate-responsibility/energy-conservation.html

In addition, Adobe even tracks over 30,000 data points on energy usage and critical operations.

Adobe’s commitment to the environment is legendary for the corporate world. In an area of relatively poor air quality, it is refreshing to see Adobe’s headquarters which are revolutionary, awe-inspiring and clean.

Paris Air Quality Worse Than Beijing

A cloud of smog has enveloped Paris – and on Friday air pollution levels were actually worse than notoriously smoggy Beijing. The French capital is taking emergency measures to reduce air pollution – over the weekend the city made public transportation, bike sharing and electric car sharing free, and starting Monday private cars and motorcycles with even registration numbers will be banned. 700 police officers are stationed at checkpoints issuing $31 (€22) fines for violators. Electric vehicles, hybrids and cars carrying at least three people are exempt.

While Monday’s air quality is improving in parts of the city, a check of the Real-time Air Quality Index (AQI) still finds “hazardous” levels of air pollution at Boulevard Haussmann in the eighth and ninth arrondissements. The fine particulate (PM2.5) index value of 880 is dangerous, and authorities have warned that “everyone may experience more serious health effects.”

Experts blame last week’s unsafe pollution levels — the worst in France since 2007 — on a combination of unseasonable warm and sunny days and cool nights with low wind speeds and precipitation. These factors kept toxic pollutants such as carbon monoxide, nitrogen oxide and sulfur dioxide near the ground instead of dissipating into the atmosphere.

France’s extensive use of diesel fuel is being scrutinized as a contributing factor to the unhealthy levels of air pollution. An estimated 60 percent of French vehicles use diesel-powered engines, and in 2011 70 percent of French car sales were diesel. Since World War II the French government has subsidized the use of diesel and there is a powerful corporate diesel lobby. The problem with diesel is that while it reduces carbon emissions compared to gasoline-powered engines, it increases fine particulates that cause air pollution. The World Health Organization has also found that diesel fumes are carcinogenic.

To curb pollution, authorities in Paris and the Île-de-France region surrounding the capital will also be lowering the speed limit, urging people to not burn wood in their fireplaces, requesting that trucks with heavy loads avoid traveling around the city, and asking factories to work on a reduced schedule to cut back on emissions.

Extreme smoggy conditions also hit northern and eastern regions of France, with the smog belt extending to Belgium and Germany. Similar pollution-reducing measures such as free public transportation have also been implemented in other European cities.

Giant Bubbles Filled With Fresh Air for Beijing Smog, Pollution Issues

Beijing’s record-breaking air pollution has spurred officials and designers to come up with innovative solutions – and the architects at London-based Orproject recently proposed the creation of gigantic Bubbles filled with fresh air! The inflatable spaces would contain parks and botanical gardens that provide fresh air to residents sick of choking on the city’s ever-present smog.

Orproject is an innovative design practice founded in 2006 that tends to explore advanced geometries with an ecological leaning. Bubbles is based on a lightweight structural system developed to mimic butterfly wings and the veins of leaves. The system utilizes a material known as ETFE, which is the same material used in China’s National Swim Center at the Beijing Olympics in 2008. This transparent and stretchy plastic could be used to create wonderful domes that allow light in while protecting inhabitants from pollution.

Orproject founder Christoph Klemmt envisions that this biome will create different micro-climates within the same space – bringing to life tropical forests next to deserts. Heating and cooling of the space will be controlled through a ground source heat exchange system, while electrical needs will be provided by solar panels integrated into the canopy structure. Their toughest challenge will be the Chinese government and developers – Klemmt was quoted in an interview with Co. Exist saying: “The big park is our dream, which depends on a lot of other people, including the government. If we were to realize this for a schoolyard, it’d be much easier for it to happen.”

China Expanding its Electric Vehicle Charging Network – World’s Largest

The Swiss power and automation technology group ABB has teamed up with Shenzhen Daimler New Technology Co to expand China’s electric vehicle charging network to be the largest in the world. Over the next six years, the company hopes to supply enough wall-mounted chargers to make the new DENZA electric car a practical, sustainable alternative to traditional vehicles in the world’s most populous country.

The chargers are expected to roll out in urban areas first, allowing for easy and rapid adoption of the new vehicles. Owners would be able to quickly charge their DENZAs at home or at readily-available public charging stations. With a lengthy battery life of about 200 miles, the network should allow consumers to travel freely within populated areas of the country. This is just the latest attempt to stir up local interest in electric vehicles since 2009, after attempts to entice buyers with government rebates failed to sell as many cars as initially planned.

The news makes sense, coming from one of the most heavily-polluted areas in the world. Air quality in parts of the country is so bad that it can be seen from outer space. The nation is doing everything it can to curb industries that release noxious chemicals into the air, from shutting down coal-fired power plants to banning outdoor barbecues and New Year’s fireworks in Beijing. Hopefully as more people transition to emission-free vehicles, the air quality will start to improve.

Beijing Passes First Regulations to Reduce Air Pollution

 

The famously smoggy Chinese capital of Beijing is finally doing something to curb its appalling air pollution. By a vote of 659-23, the Beijing Municipal People’s Congress passed a new law that for the first time will target reductions infine particulate matter (PM2.5) that pose the greatest health risk to the city’s more than 20 million residents.

A look at Wednesday’s real-time air quality index finds Beijing’s PM2.5 level at a “very unhealthy” level of 270 micrograms per cubic meter. The PM2.5 level in Beijing surpassed 500 on January 15 for the first time this year.  Beijing’s PM2.5 level averages around 227, which is far above the national standard of 34 and the World Health Organization’s safe level of 25. Amazingly, Delhi, India’s air pollution is even worse than Beijing’s with an average measurement of 473. By mid-January, Delhi had passed the 500 mark eight times.

The law, which goes into effect in March, is designed to reduce the city’s total pollutant emissions with tougher punishments for polluters, including daily fines for air pollution violations and possible criminal action for more serious violations.

As part of China’s effort to get tough on industrial polluters, the country’s environmental watchdog last year vetoed as many as 35 projects worth 118.4 billion yuan.

Wet Deposition (Giant Sprinklers) Could Solve China Pollution Problem

Smog levels in Beijing, China were found to be 10 to 15 times what the World Health Organization classifies as a health risk. The streets are still overflowing with people wearing gas masks and respirators, and city officials recently announced a fuel pollution tax to help curb emissions. Yu Shaocai, an expert on “wet deposition”, recently proposed a radical new solution that could help clear the air: giant sprinklers that spray water into the atmosphere of heavily-polluted cities.

Yu Shaocai, a former U.S. Environmental Protection Agency employee, and an expert on “wet deposition” proposed a solution which is based on a valid natural occurrence. “Wet deposition” is a process by which raindrops and snowflakes deposit polluted particles on the ground and clean the air. Shaocai’s idea is to create a new urban infrastructure and attach the giant sprinklers to the exteriors of skyscrapers in order to clear out toxins and gases from the air.

Shaocai doesn’t have specific answers to some of the technical questions. Installing giant sprinklers would involve a costly process of retrofitting skyscrapers with necessary equipment, not to mention the safety measures during storms and strong winds. The proposal is a theoretical paper, published in the January issue of Environmental Chemistry Letters, which Shaocai plans to test at Zhejiang University and in Hangzhou.

Severe Smog in North China Prompts Warnings to Stay Inside

China warns people in its northern regions to stay indoors as air pollution in Beijing is averaging 18 times World Health Organization (WHO) recommended levels.

The concentration of fine particulates that pose the greatest risk to human health was 447 micro-grams per cubic meter near Tienanmen Square in Beijing. Compare that to an average of 456 over the past 48 hours, the Beijing Municipal Environmental Monitoring Center said on its website. The WHO recommends exposure to no higher than 25 micro-grams per cubic meter over a day.

The smog adds pressure on the government to take measures beyond shutting steel plants and limiting the number of cars on the road to battle air pollution.

Beijing Mayor Wang Anshun declared an “all-out effort” to tackle air pollution by cutting coal use by 2.6 million metric tons and transforming 300 polluting companies this year, the official Xinhua News Agency reports.

Coal-burning boilers inside Beijing’s fifth ring road will be eliminated and measures taken against coal burning in the capital’s periphery, Xinhua said.

A rising number of Chinese cities have introduced emergency measures to counter smog amid increasing social unrest over the health effects of a spoiled environment.
