  1. Re:rephrase [OT] on Does Google Censor Chinese News? · · Score: 1

    First the students protested. Next the troops were sent into to Beijing. And the biggest mystery in recent Chinese history is "at this very moment, ARE these troops loyal to communist party??" Someone in the army might sympathize with the students. As reflected by the number of dissatisfied student and civilian, it is highly probable that equal dissatisfaction exist in the army. Or simply, someone just tried to take this opportunity to take over the biggest (by population) nation in the world. Armed troops in the capital had subverted the government by force in the Chinese history.

    The photo-catalytic oxidation do remove VOC including those give off by the case, provided the machine is turned on 24-hrs a day. When you use it in your office, you would switch off electric devices when you leave. There will be a net increase of VOC by the machine. These guys do suffer contacting with VOC and would hardly feel comfortable with such a big chunk of plastics around.

    Ants could smell sugar inside a plastic bag. So it is not surprising that some people can be so sensitive to VOC to a degree that makes them sick. A friend of mine who is selling PCO ( photo-catalytic oxidation ) machine, a machine that uses ultra violet light and catalyst to turn VOC in a room into CO2 and water. The machine had actually solved a lot of allergy problem by removing VOC and bacteria/fugal spores in the air.

    My friend was approached by a group of high sensitive alergy victims, who would love to buy the PCO machine if the machine cover is replaced by a metal case. Yes, the PCO machine casing is made of VOC releasing plastic!!!

    I suggested to my friend to electroplate the PVC case with chrome. That would effectively cut off a high percentage of the VOC. The question remains is, would the trace amount of VOC still hurt those guys.

    If you have experimented on chrome plating plastics, do let me know. Before you throw the switch, make sure the case is grounded.

    Every president knows cozying up with the Communist Chinese is a poison in the ballot box. It would almost certainly keep you from winning in re-election. So Clinton administration had kept a distance from the Chinese for the first 4 years and open up more dialog for the remaining 4 yrs. Similar movement could be observed in Bush admin if he's remain in White House after election.

    I bet you've never tried to do electrolysis of water. It takes a fair amount of electricity, but only tiny bubbles of hydrogen and oxygen. And it'll take a lot of trouble to store and transport these gases. So don't hold your breath for a practical fuel cell any day now.

    The interesting thing about the pot is, it has tiny pores roughly in 1 micron range. Water is actually evaporate from the pores on the WHOLE surface of the pot, making it an effective evaporate/cooling device.

    The article didn't mention the effectiveness of the device. Say, on a hot summer day, RH of 80%, if we keep the pot under the shade, could we achieve 15 degree C. A temperature ideal for beer.
