Solar Window Box Heater - 2013

Hi

I have spent the summer developing new prototypes - passive window box heaters.
These are indoor solar powered heaters, that generate up to 98f and by using small solar fans - this heat is pushed into the room. The indoor heaters sit on your window sill in full or partial sun.

I am trying to make the solar heaters, smaller - thinner, lighter.

So far so good. I have changed to interior metals used to absorb and generate heat, and have switched to a sturdy - well balanced solar fans.

Production is geared for Sept- with on lines sales in August 2013.
Glauber Salts are not a viable option.

Thanks
Dave
