'[OT] Unintended Consequences sun powered scu'

I felt compelled to share what happened this week.........
In the interests of recycling everything , I used the front lens of a projection TV to winterize a window.
The lens is a flat piece of plastic about 3mm thick.  I guess it is a fresnel lens.
I cut it to fit the window and installed it as an additional transparent layer.
I thought nothing of it until today when I happen to look at the stereo receiver sitting near the window.
The top of the receiver and two of the knobs were partially melted.
So now I am removing the plastic.

I've seen the same things happen with paperweights and ornaments/vases.

One of my friends actually had a pile of paperwork start smouldering on a sunny day.

Rather than tearing out the lens, it might have been better to move the stereo and replace it with something that stores the thermal energy during the day and releases it later.  A brick?
