Glass Turns from Opaque to Clear in a Second

glass clearThis is an interesting development for science that involves glass. You know the problem of how it is transparent, imagine if it just wasn’t.

Now, there is turnable glass that uses nanocrystals and metallic nanostructures, but it is pretty costly. That could change as Professor David Clarke and Samuel Shian at Harvard John A. Paulson School of Engineering and Applied Sciences are working on a cheaper method for opaque and clear glass.

How does it work? It uses a sheet of glass sandwiched between two sheets of clear, soft elastomer, then a coating of silver nanowires. Then all it takes is a strong enough current to turn the window opaque.

Glass opaqueIt is probably a good to make certain that these scientists perfect their process before this gets into every house, but it will be interesting to see what the world will be like without blinds. After that, it will be curtains for curtains.

Yeah, that was the best that I can come up with. Still, it is some great technology, isn’t it?
