Southern Beale talks about the the TVA electric car conference in Nashville yesterday and gives credit to TVA and Gov. Bredesen for making Tennessee an EV leader.

Tennessee has been selected by the DOE to participate in a $2500 state rebate program for the first 1000 EVs purchased in the state. This is in addition to a $7500 federal tax credit. Gov. Bredesen announced the program at yesterday's conference. Even Sen. Lamar Alexander is on board.

I like the idea of electric vehicles, especially for local errands and trips downtown and such. At some point, manufacturers may need to look at standardized, interchangeable batteries for longer road trips. This way, you could pull into a "recharging" station and swap out your depleted battery for a freshly recharged one in a matter of minutes.

The big question mark is where will all the electric power come from? The answer at the moment seems to be more nuclear power plants, which is what Sen. Alexander and TVA are promoting. Southern Beale has the right idea, though. She has solar panels on the roof of her house.

The fact that the batteries

The fact that the batteries currently weigh over sevral hundred pounds would make quick swaps difficult. Not impossible, just diffciult. Using the Chevy Volt--pairing the battery with a small gas engine also gives you the flexibility to use it on long car trips.

It works with a swapping station:

It does seem a little impractical. Another point for using hydrogen fuel cells, I guess, except for the inefficiency and energy loss problem.

And I do like the Volt system. Maybe "regular" hybrids will look at this approach as a future option.

smart power management

If energy saving practices and devices were more widely used, we could, at least partially offset the power required to operate these vehicles.
