NOBODY wants to drive their car across town and then have to plug it into a charger. NOBODY. They want to be able to walk outside, stick a key in it (hell they don't even want/have to do that anymore), plop their **** in the driver's seat, and drive away. Messing with a plug-in external charging system is 10 steps backwards in technology.

Think about how much electrical crap there is in a car now. 40 years ago, cars came with 35A alternators. 25 years ago, they were up to 80A. 15 years ago, they were at 100A. They're up to around 120A now.
Electrical demand is growing on cars every day. Safety systems like ABS pumps use a LOT of juice when they're doing their work... Then there's the everyday stuff like ignition, engine management, headlights, wipers, air con, infotainment systems, etc.. More gadgets requires more juice.

With that requirement of power means a requirement to charge while you're on the move-- WITHOUT plugging into a wall while you're stopped. People just won't do it, and they shouldn't have to.

Just because a battery can spit out 500A for 30sec (do the math genius, storage capacity of 500A * 30sec = 4.1 Amp-Hrs. A good size lead-acid battery is good for 100AH)... This doesn't mean crap when you're driving down the highway pulling 85amps for 10 hours.

Please stop believing the ricer mags and start using your brain for a change. These new batteries are neat, but they're a novelty that has a very small niche market in the auto world. A complete-loss electrical system in a race car is just about the only place they're useful.

Doing away with an alternator? No not this year or next year. 5 years down the road though?
