Windows could save the planet.

It can take the heat

And it won't crash

Windows helped to create the original industrial revolution. Now windows could minimise the damage

A new windows invention could help save the planet by illuminating the office, but keeping the heat out. Does that sound like the opposite of Microsoft Windows, which generates a lot of heat and leaves most users in the dark. That might be because it%u2019s got nothing to do with Bill Gates.

The invention by Sumitomo 3M is a new transparent window film. Initial reaction to it was cool – as you might expect, reports www.nikkei.net. But what a difference the Kyoto Protocol made.

Suddenly everyone’s desperate to cut their CO2, if only to please their boss. So Sumitomo is being over-whelmed with orders.

The window film, the Nano70S, selectively reflects the infrared part of the sun's spectrum, letting in light without neutralising the air-conditioning. With obvious energy savings. And, air born viruses don’t circulate around the building, there’ll presumably be less sickness too.

The Nano70S is a multilayer PET film 50 microns thick in total. It blocks over 90 per cent of the light with wavelengths over 780nm – the infrared end of the spectrum, in other words. The other 70% of light, the visible part of the spectrum, gets in.

As an added benefit, the window film can stop glass from shattering if Wiggins from accounts decides to end it all in a spectacular fashion.

As we all know, Windows has a nasty habit of crashing, you see.
