beat the hong kong smog: outdoor air purifier doubles as bus stop  -  personal air purifier
Hong Kong's smog is one of the biggest negatives of one of the world's most dynamic and visually shocking cities.
The views of Victoria Peak and Hong Kong Harbour are often covered up by choking smog.
Expats complain that some people have moved to Singapore, while locals who want to live a better life for their children are just immigrants.
There is good reason: air pollution in Hong Kong kills about 3,000 people a year.
There is now a new way to highlight the problem if it is not solved.
Real estate developer Sino Group works with engineering companyand-
Arup, an urban design expert, will develop a roadside air purifier that will provide some hope for relief.
The purifier is like a large outdoor version of the air purifier, which is usually found in the house and apartment.
The prototype is located on the busy Queen's Road East in Wan Chai, Hong Kong, and looks like a tram or bus shelter.
The device absorbs air near the ground and, after passing through the filter bag, removes not only PM 10, but also finer PM 2. 5 capsules (
These measure the size of the particles-smaller particles are more dangerous)
And deliver fresh air through the blinds at the top.
The fresh air forms an air curtain, so anyone standing inside is largely isolated from the particles.
Preliminary data show that particles are reduced by 30% to 70%, and there is nothing worth sneezing.
Jimmy Tong, an engineer who helped develop the purifier, said the device could also help create air flow, reduce street canyon effects, and buildings stop air flow.
Prototype, this is installed in a few months.
The weekly trial also included a sensor to collect real-time data and to be associated with the government's Air Quality Health Index, allowing hourly comparisons with street-side monitoring stations.
If the experiment proves to be effective, Sino says the device can be placed outside the bus station, the tram station and the building.
Power may come from solar panels, or even from piezoelectric, which is generated by stepping on special energy tiles.
This purifier does not solve the air quality problem in Hong Kong, but at least it can give commuters a little relief from roadside pollution.
It can also provide cooling fog for Hong Kong's hot summer months for additional relief.

The son of Robert Ng, head of the group's sustainability committee, is well educated and likes to solve environmental problems with technology.
Earlier, he tried a system that uses the building's water supply to generate electricity using micro-electronic equipment. turbines.
Although the air purifier is impressive, it will make more sense-and it will produce more --
Achieving health improvements-if the government seriously considers reducing streets --
Control contaminants by leaving dirty vehicles off the road.
The government plans to phase out 82,000 old diesel buses and trucks in the next five years.
Despite calls for a section of central Hong Kong to be dedicated to pedestrians, the government responded by building more roads and encouraging more cars.
The fleet has grown by 50% since 1991.
The ban on idling engines for parking cars began in 2011, but mainly because they were almost completely unexecuted. Meanwhile, smog
Contaminated commuters can hope that the experiment will be successful and outdoor air fresheners will be promoted throughout the city.
As for China, while it has done an impressive job of using technology, it may stand out from cross-cutting
The script of the city's rival Swire Properties, and released detailed results of its building's electricity consumption.
Technical fixes are helpful, but for a buildingthird to one-
With half of the power consumption, developers also need to make sure they collect and use the hard operating data they need to run the building more efficiently.
