Keep your car cool!

Today I'm writing to tell you about a cool summer product, the Auto Cool Solar Car Fan! You know how when you park your car in the sun and leave the windows closed it gets really really hot throughout the day? Scientifically, that's because the energy from the sun is instead going into the motion of the air molecules trapped inside your car - that motion is what we call (in English) heat! (Of course, in physics we'd call it temperature, or maybe instead say that temperature is entropy, but that's a different issue for my other blog, Modern Science.) The Auto Cool Solar Car Fan instead takes that solar energy pouring into your car and uses it to power a fan - so it absorbs some of the energy that's being wasted on heating your car, and then uses it to keep your car cool, a double whammy. The whole concept is a lot more proactive than just putting up sunshades, and anyway in my new car (2006 Honda Civic) it's going to be hard to find sunshades big enough to fit the whole huge window. The Auto Cool Solar Car Fan is one of those "as seen on TV" items, and it looks to be a decent price at around $15, so why not give it a try?
