Don't Pee Here We Will Pee Back

San Francisco is testing an ultra-water-repellant paint on walls in areas fraught with public urination problems. 

The paint is designed to repel the urine and soil the offender's pants.

 "It's supposed to, when people urinate, bounce back and hit them on the pants and get them wet. Hopefully that will discourage them.

 We will put a sign to give them a heads up," said Mohammad Nuru, director of the San Francisco public works.

 A Florida company named Ultra-Tech produces the super-hydrophobic oleophobic nano-coating that was also recently used with success on walls in Hamburg, Germany [video] to discourage public urination.

 Signs posted there warn, "Do not pee here! We pee back!"

...but it's not all good news

However there are serious concerns that some nano particles may have a detrimental effect on the environment if allowed in any significant quantities into the waste streams, onto the land or into the sea.

Respiratory ailments will increase as nano particles are released into the environment.

Already they have a name for this calling it COPD. 

Nano technology will increase human mortality.

There is growing concern about the unregulated usage of nano particles in products.


Dangers come in small particles
Hundreds of nanotechnology applications are already in commercial production despite a huge health and safety question mark. Hazards looks at how an industry the safety authorities admit they know precious little about has been allowed to grow, unregulated, into the biggest thing since the microchip.
