If you don't like to "do windows," you're going to love Bharat Bhushan.
The Ohio State University professor of mechanical engineering is developing technology that could result in windows that actually clean themselves.
Now, clean windows aren't exactly at the top of Bhushan's worry list, but it turns out that the same technology that can reduce friction in the moving parts of tiny devices could also keep your windshield clean.
And we know that because awhile back Bhushan got all worked up over lotus leaves.
Stay with me here.
"The primary application is nano-technology," Bhushan said.
You might say he lives in a very small world, where new devices are being developed at a rapid rate on a scale that almost defies imagination. Motors so small they can power robots smaller than a dime. Sensors so tiny they can't be seen, but so sensitive they can detect even traces of toxic chemicals.
All those tiny gizmos face a common problem, friction. And since it isn't possible to climb inside with an oil can, some way has to be found to virtually eliminate friction between moving parts for the lifetime of the device.
