Solar panels on Prius?

Anyone see the announcement that the future Prius is supposed to have solar panels on its roof to operate the air conditioning? This would allow you to put the car in the mode where the gas engine stops at a traffic light (for instance) but you still get to have cool air. Up to this point, if you want cold air, you have to keep the gas engine running. It's a neat idea but I have no idea how they will actually do it.

The solar panels are supposed to produce 2000 to 5000 Watts. With the best will in the world, I don't see how this can be true. I have 21 large solar panels on my house, the system is only 5 years old and produces a maximum of 3000 Watts. No way a panel small enough to fit on a car's roof could produce that many kilowatts. I don't think even NASA has solar panels that efficient. Anyone know what's really going on?

A "Fith Wheel" type trailer (All Aluminum)

towed behind the Prius,full of Solar Panels?

Toyota obviously has their hands on some of that Extraterrestrial Technology.

AND ALSO:

(That means the Electric drivetrain will be interconnected with the compressor
and have the ability to dis-connect the compression drive motor from the
electric.)

Current Prius already does that. A/C compressor is driven by an electric motor, not by the engine.

The solar panels are completely a political/sales move. They won't be able to do more than trickle charge the batteries, power clearance lights or run a ventilation fan. There is no way it can make enough power to run an A/C compressor.

I agree with that. They are physically not big enough to be useful. Gotta wonder if they will survive a Texas hailstorm too......

They said it would supply PART of the power required for the AC. It would probably be more useful if it charged the battery.
