I ran into this article recently that I think is worth sharing. For those of you who have driven into an open parking area to park on a hot summer day only to find the shady areas are all taken. You have looked everywhere, dreading to shut down the pleasant air conditioning in your car, you have been forced to use the brightest spot to return and find the heat in your car could be used as a glass blower's furnace and it's going to take the ac at least 20 horrible minutes to cool down and get comfortable again, the answer is finally here.
