Popular Post webfact Posted February 18, 2020 Popular Post Share Posted February 18, 2020 Air purifier on bus roof likened to GT200 hoax By The Nation With the Transport Ministry planning to install another 3,000 air purifiers on bus roofs, Jessada Denduangboripant, a lecturer at the science faculty of Chulalongkorn University on Sunday (February 16) likened the project to the fraudulent GT200 bomb detector case several years ago. "I asked the opinion of a researcher at The National Astronomical Research Institute of Thailand (Narit) if installing air-filter boxes on the roofs of 500 buses would help solve the air-pollution problem in Bangkok, as claimed by the BMTA," he said. For an easy comparison, the Narit official said: " it is like a single dead pixel on your phone, hardly visible". In short, it is a fraudulent tool similar to the GT200 bomb detector, but born in 2020 when people are not easily fooled” Jessada said on his personal Facebook page. However, BMTA director Surachai Eamvachirasakul, on Monday (February 17) , claimed that the air purifier actually works. The prototype machine, he said, sweeps air containing PM 2.5 particulate matter at an altitude of no more than 5 metres. When the bus is running, air travel along the roof and pass through the filter box in a natural process without the use of electricity. Filtering materials used in the air purifier can be purchased online at low cost, he added. The working principle of the prototype air purifier comes with the same invalid argument as the GT200 bomb detector, Jessada said.

It would be good to see some details of what is being claimed, if it apparently has flawed logic. Link to comment Share on other sites More sharing options...
Popular Post Wiggy Posted February 18, 2020 Popular Post Share Posted February 18, 2020 The bus in the picture is from this article: https://www.bluestarbus.co.uk/introducing-bluestar-breathe However, that only refers to filtering PM10, and not PM2.5. That said, the article re Bangkok buses may have nothing to do with the accompanying photograph. 3 Link to comment Share on other sites More sharing options...

By all accounts there is some merit in this idea but it's hard to fathom how it can be effective away from the immediate roof level area of the bus when those pesky particulates get everywhere .. 1 Link to comment Share on other sites More sharing options...

I think the rookie who provided the photo forgot to tell the other rookie who wrote the article that they must always write at the end of it the source of the photo and the name of the photograph if it is not a personal one . an oversight, most certainly? 1 Link to comment Share on other sites More sharing options...

PhilAtUbon Posted February 19, 2020 Share Posted February 19, 2020 I am so embarrassed and humiliated that this nonsense was adopted in the town of my childhood – Southampton. Even if I were still the spotty youth I once was, I would be mortified that this utter rubbish was given the green light in my home town. If only Thailand could pick up on proper technology and advancement from other cities and countries rather than the most stupid and cruddish ideas.
