- Curtains and blinds may soon be a design choice as opposed as to a tool for privacy. Windows that can transition between clear and cloudy in a second may soon be a reality thanks to technology below development at Harvard University'south School of Engineering.

Windows that can modify opacity or color already exist but rely on electrochemical reactions that are expensive to manufacture, particularly on a commercial scale.

"They're all very effective, although I think ours is even more effective. But the huge problem is how you create large areas, windows, and the cost," said Prof David Clarke, a material scientist at Harvard. 

The scientists have figured out a method to produce windows that go from clear to cloudy at the flip of a switch in a way that's both cost effective and commercially viable, according to a study they published in the journal Optical Letters.

The team uses elastomer rubber coated with nanowires that adheres to glass to disperse light when voltage is applied. 

"When you apply a voltage to them relative to some background there is an appealing force between the nanowires and the substrate that deforms the elastomer," said Clarke. "Elastomer rubber is very soft and so the surface becomes rough, and it's that roughness that scatters light," Clarke added. 

Samuel Shian, an author on the study, believes scaling this technology should be commercially viable because the reaction is physical rather than chemical. Current chemical-based controllable windows utilize vacuum deposition to coat the glass, an expensive process that deposits layers of a material molecule by molecule.

But to transition this technology to the genuine world will get a bit more fine tuning in the lab, according to Shian. 

"When we're talking about windows we're talking about several feet by several feet... we're talking from tiny to large, so things necessity to be optimized," he said. 

One obstacle is developing a thinner elastomer that'd require lower voltages to deform. 

Harvard has filed a patent application on the technology.
