A bathroom that cleans itself
Univ. of New South Wales ^ | 2/7/06

Posted on 02/08/2006 10:12:06 AM PST by LibWhacker

Cleaning bathrooms may become a thing of the past with new coatings that will do the job for you.

Researchers at the University of New South Wales are developing new coatings they hope will be used for self-cleaning surfaces in hospitals and the home.

Led by Professor Rose Amal and Professor Michael Brungs of the ARC Centre for Functional Nanomaterials, a research team is studying tiny particles of titanium dioxide currently used on outdoor surfaces such as self-cleaning windows.

The particles work by absorbing ultraviolet light below a certain wavelength, exciting electrons and giving the particles an oxidising quality stronger than any commercial bleach.

These nanoparticles then kill microbes and break down organic compounds. And because surfaces coated with titanium dioxide have another property called 'superhydrophilicity' -- meaning droplets do not form -- water runs straight off the surface, washing as it goes.

Presently, titanium dioxide can only be activated by the UVA present in sunlight. But the UNSW team is working on ways to activate titanium dioxide with indoor light.

The team is modifying titanium dioxide nanoparticles with other elements such as iron and nitrogen so they can absorb light at longer wavelengths.

Lab trials show that glass coated with the new nanoparticles can be activated by visible light from a lamp to kill Escherchia coli.

"If you've got this on tiles or shower screens you don't need so many chemical agents," says Professor Amal.

So far the team has been working at laboratory scale. "It's probably a year before we can talk to industry and test outside the lab," says Professor Amal.

If this new technology also picked up my sons' skid marked drawers from the floor,I'd be happy!

So it's a self-disinfecting bathroom, not a self cleaning bathroom. And here I was imagining some robotic/water stream contraption thing that made it look spotless...

Already done, I think Tim Allen had one of those in "Home Improvement".

As a mom of three boys, 4 if you included my husband this sounds great.....I am happy with the removable toilet seat that I bought at Lowe's .....as good as marksman they are when hunting they can't seem to hit the toilet

There are some titanium nitride coatings avvailable on knives that supposedly stay activated in any light to kill all bacteria and viruses.

I was thinking they could coat every square inch of the interior of a house with this stuff, put a big drain in the middle of the floor, sprinklers in the ceiling, and a person could just hit a button when he left in the morning, and come home to a spotless house in the evening... Like a giant dishwasher.

All I want is a true self cleaning litterbox. And no, none of the automated ones work well.

Yes, indoors, it will require a water stream. Beats having to scrub, or knowing somone never did scrub when they were supposed to.

I have patented a technique for self cleaning laundry as well, especially suitable for bachelors.

What you do is leave filthy clothing in a huge mound, akin to a compose pile. The bacteria eats all the dirt and grime, leaving the clothings totally clean. The exothermic reaction from the bacterial colony generates heat which removes all wrinkles from the clothing.

No doubt, this new high tech toilet is a result of threatened tightened border security and a fear over the lack of finding an illegal alien to do a job Americans won't do.

I like your thinking. However - what about the linens and upholstery? Guess all would have to be vinyl. Something to think about - I could grow to love vinyl.

how about some nanoparticles to improve those boys aim?
i'd sign up for that! ;)

Seattle has placed some of these self cleaning toilets around town - to be used by the homeless (Winos). Cost if I remember, was over $200,000 each. As much as taxpayers complained about the cost the city did it anyway.

Great! Now if we can only make people flush the toilets when they get through. Women don't flush public johns because, they don't like to touch the 'dirty' handle. They leave the flushing to the next one using it. I hate that!

".....as good as marksman they are when hunting they can't seem to hit the toilet."

You know what might cure that? Threaten to sit and watch them EVERY time they go in to the bathroom. Their "missing" might end verrrrry quickly. Also, make THEM clean up.

Man! Have they never heard of tissue over the handle??? I think that's just plain laziness. You're right, it's disgusting!

With 2 shedding black dogs in the house.

Their effluvia will now be sterile.

I read an article last year about something very similar from the Japanese. They have developed tiles, paint, etc. that repel germs. It's a great idea. I think it won't be long before this type of material is on the market.

Oh, do tell me about this removable seat? And what is up with them (my two boys) not being able to hit the toilet???

I actually want someone to design a giant funnel that fits into the toilet.

Or an absorbent pad that fits around the toilet base (including the back of the base) that can then be picked up and thrown away.

Or a stand-alone stand-up urinal that you can hook up to the toilet until your boys learn to aim.

Somehow, I'm not sure I'd want to live in (even a very clean) toilet. What if I accidentally flushed my self ?

Amen. I swear it took us 3 different models, and countless cat "incidents" to figure out the thing didn't like the self cleaning litterbox. I swear... @#$%!

I saw this on "I Want That" on HGTV....I goggled this and the seat they were talking about was too expensive. The one I got at Lowe's is by Westport, installs like any other seat but you need to flip the two caps to the right and lift the whole thing off and clean....also an added bonus is that it self closes so you don't have the slam affect. I paid under$30.00 for it and maybe you could find it on the web even cheaper....you will love it.....I know I am getting older when devices like this make me happy.
