Ideas anyone?

So the other day I'm standing on the balcony at work having a smoke, and looked down into the parking lot, the same area where we always have able bodied clowns parking in the invalid parking bays, and I saw this:-(Okay, I could have rotated the pic b4 I posted it....!)
So here's what came to mind.
Why not make the sunroof inner ( the part that keeps the sun out), make it a solar panel. Then you could run either a small extractor fan, or a light duty aircon off of it, to keep the care cool whilst it's parked - in the sun?

Doff u say? I think not. In fact I think it's a great idea, and one that would probably fly. However, who / how does one go about putting this proposal to someone from the car industry?
Any suggestions?

Salagatle!
