On a bright day at noon solar cells produce about 10 watts per square foot, so my car would need 22,827 square feet of solar cells, that's not counting the additional air resistance caused by the 151x151 foot square mounted on the car's roof and the "WIDE LOAD" banner I'd have to place on the back.. And I still couldn't get to work at night or on cloudy days.  John K Clark 



Ja, your car can produce 306 peak horsepower, but its average usage is less than a tenth of that typically, and you can cut that in half if you allow half again more time to make the trip.  If trips take half again longer than they once did, we start thinking of ways to not go, or to combine trips, saving even more.


I have the notion that we will tear around like our asses are on fire so long as it is cheap to do it.  Then after it isn’t cheap anymore, we will stop.  Then we will have a whole new pile of problems.  Now we waste because we can.
