Self Cleaning Glass

Posted by ryan at 02:54 PM in science . | 13 Comments

The Pilkington Activ glass has a special nano-scale - extremely thin - coating of microcrystalline titanium oxide which reacts to daylight.

This reaction breaks down filth on the glass, with no need for detergent. When water hits it, a hydrophilic effect is created, so water and dirt slides off.

Maybe dirt ejecting clothing is not too far off.

Hey, there is already those Dockers (I think) that you can spill your drink on and it slides right off! But when will we have pants that use nanotechnology to climate control your body, that's what I'd like. Who needs indoor heating/AC when you're wearing it.

This also reminds me of some paint that was developed recently which breaks down pollution, so if you had a city using this paint on all their buildings it would be a much cleaner city. Combined with activ glass, it would also look like a much cleaner city.

Nano is becoming a catch-all term that everybody wants to use to describe their products nowadays. Like plastic. I'm still waiting for the real promise of nano, nano-machines / nano-medicine.

I agree that everyone is throwing around "nano" to make their product sound much more interesting than it really is.

It is my theory that the Dockers, paint and these windows are all just coated in some form of teflon...

Nanoflon?

Maybe there needs to be some sort of certification process for products to be nano. (Like "kosher".)

I'm not nearly as brilliant as I had hoped. After I thought I had coined the term NanoTeflon I did a search for it on Google. I got this: FUTURESPEAK - other uses for Teflon - Interview

"Most people know Teflon as the nonstick coating that keeps their eggs from sticking to the pan. With your invention, what other uses could there be for Teflon?" ... "You can pour water on a piece of cotton that's been treated, and the water doesn't wet the cotton at all." ... "Possibilities include outdoor wear that's stain repellent" ... "Other major uses are chemical or biochemical applications, such as membranes used to separate particles like viruses or dust, leaving toxins behind." ... "Gleason's challenge was to create nano-Teflon."

How about some self cleaning nanotube hydrogen sensors?

This and the windows seem to use the same concept of light cleaning really small things.

Maybe the water byproduct produced by future hydrogen cars can be used to (besides make coffee) wash your car. Also, just imagine when we are pooping in Britas.

In the book Dune they live on a desert planet and wear these water conservation suits. Everything is recirculated. Everything.

Imagine when we are pooping in Britas? I just pooped in mine.

awesome.

Tracy, you didn't even know did you? Those things work great!

Isn't there a saying like "don't eat where you shit"? Does this violate that?

Also, there is a company that makes these large portable devices that uses solar power to suck water out of the air in the desert. Unfortunately, it's a big mechanical device that's a bit out of the price range of those who really need it but perfect for ... U.S. military use.

I'm still curious how one uses these poop suits.

I could only imagine how it would work.

The book doesn't go into it too much. They just say "Urine and feces are processed in the thigh pads."

Meanwhile, at a local restaurant urine and feces are processed into "pad thai"...
