Prague, in the summer, is a beer-drinkers paradise. Beer gardens dot the city, the people watching is unparalleled, and the long, warm days make it wonderful to sit inthe shade of an old tree and sip a fine Czech pivo while writing.

Unfortunately, that same pleasant sun makes it nearly impossible to see the screen of a typical laptop. Even in the shade it’s just too bright out there. I had been designing in my head a special “writing outdoors” laptop with an ultra-bright screen. They have them, but they are power hogs, so the rest of the computer would be taken up completely by batteries. There would be no optical drive and maybe even no hard drive, just enough flash RAM to hold the OS and Jer’s Novel Writer, and a USB port to use for file transfer.

But then I noticed something. I can hardly see my phone screen at all when I’m wearing my shades, but if I turn it 90 degrees, there it is. The light is polarized. And there lies the key to outdoor laptop use. Construct the screen so that the light is polarized in a particular direction. Create glasses that are extremely dark except for light polarized in that one tiny notch. As Voltaire would say, “Voila!” The relative brightness of the screen would be increased without burning through batteries.

I don’t know what it would take to make lenses that were that specific to a particular polarization angle and very dark in all others, but I bet it could be done.

Best of all, Geeks would finally be able to get some fresh air and sunshine.
