Polarized Filters
In physics our professor explained and demonstrated how they work and I had some understanding before, but when he rotated one filter superimposed on another, I had an idea.

If you had round windows on your house or... portholes on your ship :P, instead of having shades, could you attach one filter to your window and frame the other one to rotate as you desire?

interesting thought, problem is that they are always tinted so you would always be losing a significant amount of light. I also would not want to see the price tag on a 4ft polarizer :eek:

Yes, I figured that it would be prohibitively expensive. When the professor explained the filters, it sounded like they somehow worked as solar panels, which I must have misunderstood.

I keep visualizing a round filter in the middle of a rectangular window! :)
