#2107: SunShutter

Everybody is keen to avoid skin cancer but the beaches are still full of people attempting to get some kind of low-level sun tan.

Rather than insist that everyone wears an all-over bodysuit including a rubber mask (fashionable in China) today’s invention is a beach umbrella that gives its user a controllable exposure to the sun.

Alternate segments of the umbrella are free to rotate as a set and thus allow sunlight through in the form of flashes (2 sets are shown, but several might be necessary for an even illumination).

The segments would be driven by a motor in the handle.

Enter one’s sun lotion factor, latitude and the time you want to spend in the sun and the umbrella would spin at the correct rate to enable only a light tan.
