Has anyone seen the infomercial for Auto Cool? It is a small solar-powered device that you place along the top of your car's window as you roll it up. As positioned a small portion protrudes outside the car. The solar power activates a small fan that sucks out the inside heat so that your car's interior won't become hot as it sits under the sun.

Assuming it works as advertised, I was just wondering about the feasibility of incorporating such a device in the PhUV. It retails for P1995 but looking at it, I would estimate production cost to be under P500.
