| | | Posted by wannabeotaku I like the idea of hybrids, but they just don't work out once you get them on the street. If we had a real performance hybrid, I'd be all for it. The one thing I do like about the Pious is the optional solar panel package. Less of a load on the engine to cool the car from the summer heat. If the panels keep the car cool on a sunny day without costing me anything above the price of the option, then awesome. I just don't think I'll but a car for such an insignificant option, though.
| 1 watt = 1 volt X 1 ampere 1 watt = 3.41 BTU 746 watts = 1 horsepower 1 horsepower = 746 watts. 1 watt-hour = 3.41 BTU heat per hour A car AC will be around 10000 BTUs. So you just need 34000 watt-hours from your solar panel. A 14x20" solar panel could deliver 20 watts, if it's under full noon sun - that's 10w per square foot. The roof, hood, and trunk of a car would be about 105 ft^2, or 1.05 kW. A full-car solar panel would give you about 3000 BTUs of AC. Their claim of "1200 watt-hours per day" sounds about right, considering their panel is smaller. But who wants to park in full sun?

| The idea isn't to keep the car cold, it's to keep the car slightly cooler. If it could maintain 90 degrees F, then it would be much easier to cool than if it were 120 degrees F. I'm sure it's not worth the expense, but I'm a technowhore. And the use of Pious was indeed intended. It's very accurate. I know of only one Prius owner that's not a complete snob about it. Ironically, his 1965 Mustang got more miles than the Pious. He loaned the car to my uncle, who crashed it into a tree to avoid an oncoming driver, and never replaced it. apparently, you can do a sweet burnout with the Prius if you can disable traction control fully. I want to see it in person if it's true.
