Umbrollar

Okay ... this is my first post so here goes:

Have you ever been to the beach; set up your towels and coolers and most importantly your umbrella only to fall asleep halfway through a good book and awaken finding yourself burned to a crisp and the umbrella's shadow shading some freeloader a few feet away. Well, I haven't ... but I imagine someone has. And here's my answer: AN UMBROLLAR (soLAR UMBReLLa) with a base that has some sort of motor that would allow the umbrella to rotate autonomously. Where the canvas of the umbrella would normally be are instead a bank of solar panels powering the small motor on the base of the umbrella. Now this part is key ... small photoreceptor(s) would be mounted on the top of the umbrella detecting from which direction the light is most intense and sending the information to a small onboard computer which would, in turn, reposition the umbrella to best inhibit the sun. Taking the photovoltaic umbrella (2) one step further. Plus its a BEACH umbrella ... one of the few reasons you would use an umbrella in a sunny situation and excellent solar ... ness.
