Battery pack upgrade for Prius claims 150MPG

Relating this to MPG is totally bogus, given that it is plugged into the power grid. Reminds me of the story, way back when foreign cars in the US were rare. A guy bought a VW and was bragging to his coworkers about his gas mileage. A couple of his friends started adding gasoline to his tank in the middle of the night. His mileage kept getting better and better. One day they quit, and he had it into the dealer to see what was wrong.

That is sooo funny. Good prank and no one got hurt, nothing damaged !!

agree that it's a bogus solution - if you take power from the grid, then you will be using the most marginal generators - just maybe wind, but more likely keeping old coal fired stations going so the net environmental effect is worse than gasoline, and the overall system efficiency is going to be bad...

Wrong! Think of all the energy it takes to refine then deliver your gasoline to the pump. Generating electricity and then using it in a car is much more efficient. So what you're saying is it is much better to have millions of cars each generating its own pollution in cars which are probably not tuned correctly anyway thus spewing out more pollution is better? How clueless. Plus there ARE actual clean coal burning power plants with zero emissions (except for CO2). But even then the CO2 output is wayyy lower than your average poorly tuned car.

Me too. Headline shell games. Energy is energy and it had to come from somewhere. I guess if we had more nukes we'd have less global warming. Now, there is an inconvenient truth !!

www.youtube.com also mentions mounting solar panels to prius , that is a better solution ,you don`t burn that extra coal
