Not a video (yet). Exotic air "cleaner" vs Dremel.
Added 2020-05-16 16:54:42 +0000 UTCThere's something just a little bit suspicious about this high profile air cleaning system. Lots of marketing hype and "molecular science" that could only be proven by a very skilled lab with a large budget.
The bit I can analyse is whether it produces ozone, which I suspected it did, since the ionising needles have a metal ring in front of them that is similar to an ozone generator.
The unit does apparently produce both positive and negative ions from each module simultaneously, which I wasn't expecting, as it alternates power between sets, and their wire colour is different, although the modules all have the same label.
To test whether ozone is produced I powered a module on its own and when placed in a closed container it does produce a smell of ozone in a matter of seconds. There's also a faint corona discharge on both emitters in a dark room. (Which is how the ozone is being generated.)
The ozone is not produced at a high level, and may be part of the reason the unit has a very powerful fan to dilute it with lots of air.
The marketing videos don't help by showing excited Japanese youths in white boilersuits doing lots of "tests" involving getting a faint whiff of strong odours on thin cloths and placing them in closed containers with the units, and then marvelling at how the odour has gone.
There also appear to be a LOT of "truth" style videos on YouTube that appear to have come from their marketing department. One shows an ozone monitor in a sealed enclosure showing zero ozone detected. Well I guess they need a new ozone meter then....
I've not got a problem with low level ozone generators, but there's a lot of 5G-grade hysteria and misinformation about it on the Internet. So I wonder if this unit really does "split water" into charged hydrogen and oxygen as it implies, or if it's a bit of theatre surrounding a unit that is possibly just a very low level ozone generator.
Initial investigation inside one of the 12V modules looks like a small voltage booster possibly followed by a single diode rectifier, charging a capacitor and then dumping it via a GDS96 diode (possibly a SIDAC?) through a conventional step up transformer. What I can see so far on the front is a pair of high voltage diodes, possibly feeding the positive and negative needles from either a single or double winding.
Comments
There are small wall mounted devices commonly used in food preparation areas that have a fan blowing air across a small UVC tube, partly to sanitise the air and also to produce a slight amount of ozone in the air. Interestingly the very expensive "packaged" tubes also come with a "backup battery" that is clearly being used as a lifespan indicator by controlled discharging of the battery until it reaches a threshold voltage to indicate that the tube needs changed.

2020-05-20 12:46:25 +0000 UTCOn the subject of air cleaning and UVC, I've just had an email from my dentist including the following paragraph. "We have invested in Air sterilisation systems and fogging (misting) machines. Air sterilisation systems: These systems use UV-C light. Many premises worldwide are now adopting UV-C to sanitise premises, with proven technology killing bacteria, viruses, microorganisms and mould. The systems we have invested in utilises powerful C-band, ozone-free, UV radiation to safely and efficiently sterilise and recirculate up to 800m3/hour of air per unit."
2020-05-20 10:24:48 +0000 UTCI would have thought that too.

2020-05-16 23:48:38 +0000 UTCIf it splits water into oxygen and hydrogen why not stick it in a box with steaming water and after a while see if a match explodes the box? Although there may be ways to gather smaller amounts of hydrogen for testing :)

2020-05-16 21:48:03 +0000 UTCI dont belive thats how they interact. or more to the point. the + & the - dont interact. the + ions interact with each other. but the - ions...well. they dont. non the less, this is not my speciality by any means, I could be missinformed. but that is how I understand it. or dont as the cse may be.
2020-05-16 19:59:12 +0000 UTCif they produce both +ve and -ve ions simultaneously, won't they just collide within inches of the device and cancel each other out?

2020-05-16 19:18:24 +0000 UTCYou need a new channel Clive, "Clive's Something Fishy" or "I Smell a Rat" it would go off, everyone loves a good myth busters type show. Great work mate.

2020-05-16 18:27:23 +0000 UTCIn this instance the very visible corona is the ideal source of ozone as well as the inevitable nitrous oxides. It's worth mentioning that many of the people who extoll the hazards of nitrous oxide production by ozone generators also drink cappuchinos with cream on top frothed with nitrous oxide.
