Yesterday I was beat from a weekend of skiing, and just wanted to relax in front of the TV for an hour or so. But it was so sunny outside, and I felt like I should be out enjoying the sunny weather. Of course, bringing a laptop or portable DVD player would give terrible glare, and the brightness just
isn't there to enjoy a movie outside.
The Sunovision has two possible technologies that could be used to make it function, both using very little power. The first is a simple color LCD screen with a white frosted backing. This is held between your face and the sun, which provides backlighting for the display. The second possiblity is an array of tiny mirrors as are used in some projection HDTVs. The direction of the sun and your face is determined, and sunlight is reflected to you. If the exact position of your eyes can be determined this would also allow for a 3-D display.
Does an outdoor TV set kind of ruin the point of going outside? Yes. But I'd likely use it anyway.

||You could use an overhead projector style clear LCD panel (if they still make them - last time I looked, they were incorporating the projector technology directly into the LCDs) - but place it in front of a sunlit white surface. Looking directly at the sun is never a good idea, even through frosted glass.

||The OLPC XO-1 has a (monochrome) full-sunlight mode. It's not readily available to ordinary consumers, but it shows that it's doable.
