Think it smells on Earth, try living in a space capsule for a few months. If you want to discuss smells in space, you have to see this: There’s a new technology which may be applicable to future manned space exploration. O.ZONELitesTM are a spiral shaped light bulb coated with titanium dioxide (TiO2). As air passes through, the result is oxidation, which attacks and destroys microbes by disintegrating their DNA. The reaction also kills dust mites and mold. And, eliminates odors.
According to some speculators, this may be of great value not only to Earth, but to controlling the confined area of the International Space Station (ISS) and of any other space faring unit. Theorists suggest that the bulbs could help to control contagion as well as slow the rate of organism mutations that could lead to killer microbes.
At only 23 watts, the bulb emits as much illumination as a 100-watt incandescent bulb, making it energy efficient as it neutralizes smoke and odors. According to deMartino and O.ZONE LitePresident William C. Stone, O.ZONELite uses no toxic chemicals and the product is more cost-effective than HEPA filters and air ionizers, which only trap airborne particles.
O.ZONELite is headquartered in Deerfield Beach, Florida and the bulbs may be purchased by calling the toll-free number (800) 494-8292.

My impression of this product is that the technology is unproven in the field in which it claims to be effective (the killing of micro-organisms) and the manner in which it claims to do so (the production of free-radicals) is just as likely to cause severe harm to any human, or other animal, cells it comes into contact with.
True, I have only cast a cursory glance over the ‘in press’ (I’m certainly not going to refer to it as ‘published’) data that the commercial web page points to, so cannot give any more than an initial impression, but it is well known that free-radicals can cause severe damage to human DNA, although this is usually caused by free-radicals produced within the cell itself by normal metabolic processes. I can’t help but feel that breathing in free-radicals would not be a good thing to encourage, particularly in individuals who already have compromised respiratory systems.

Nice ad.
NASA already tests for smells.
I saw no mention of a unit with a fan, needed to circulate air in zero gravity. But in the real world air is being circulated in the ISS. Also in the real world humans are not aseptic, and not all microbes are floating around anyway.
Also omitted that ultraviolet chambers and other air-sterilizing technology exists, as well as that intense ozone is one of those technologies (yes, a safe sterilizer has to stop the ozone from being released). Also available are activated charcoal filters which remove odors.

Was this posted by a sales hack?
I thought I was watching a late night infomercial there for a minute. WTF?
BTW, Ozone is pollutant. Ever see what it does to a rubber band in chemistry lab? Oxidants, bad. Skepticism, good.

Read what it says… the product doesn’t use Ozone. It’s just badly named. It uses Titanium Dioxide now being used in sun blocks and clothing. Only recently have they found ways to apply this to other uses

Self-cleaning clothes – a reality soon, say scientists
Hong Kong : 16th June 2004
Scientists at the Hong Kong Polytechnic University discovered that tiny particles of titanium dioxide, a substance that reacts with sunlight to break down dirt and other organic materials, can be coated on cotton to keep clothes clean.
The particles are less than 20 nanometres across – about 2,500 times smaller than the width of a human hair and transform grime in to even smaller particles, such as carbon dioxide and water molecules, when exposed to sunlight.
To make the fabric, scientists dipped cotton samples in titanium dioxide for about 30 seconds, removed them, padded them dry, and then heated them in an oven for 15 minutes. They completed the coating process by soaking the fabric in boiling water for three hours.
Along with self-cleaning clothes, the resulting fabrics also could be used to tackle dirt, environmental pollutants and even harmful microbes, they said.
Cambridge University Chemical Engineer Bob Skelton told Nature magazine that Titanium dioxide, in the presence of ultraviolet light would oxidize a wide range of organic materials. More research is needed before self-cleaning clothes are available at high street shops.

…if the bulb could be shaped so that it creates a natural air flow, sort of like a chimney draws smoke up. This would allow them to more useful in space and perhaps on Earth. The only concern I would have is how the oxidation is removed from the air the bulb has processed.

Crap like this made it to the front page because 8 people voted that it be there – looks like a Scoop commmunity is actually starting to take hold here on SciScoop. And I will note that this article has produced more of the kind of interactive commentary I’d like to see here than just about any other story I can think of lately, including all of my own.
Of course, there’s still room for improvement seeing as how one of the posts is entitled “You’re An Idiot”…

Also in sunscreen. Great for my tennis store. I can sell sunblock, racquets and self cleaning clothes in a store that smells fresh and clean.

…over the fact that titanium oxide reacts with “organic materials” (as noted in Anonymous Hero’s July 4th comment) and turns it into carbon dioxide and water.
Now imagine I’m wearing clothes treated with titanium oxide, against my skin! I could end up in a puddle like the wicked witch of the west…

So just step out in the sunlight, become one with Nature, and the clothing is immediately clean and can be recycled for someone else.

Can someone please point me in the right direction on this? How do I find out if the of this light bulb are true?

go to ozonelite.com and check out the research reports. Additional research is readily available by just doing a google.
