It is really a very stringent requirement of the present day that automotive batteries as will get some form of Moor's Law. Straubel's quote of 7 to 8 percent increase in the battery performance every year is not sufficient for usage of batteries for automotive purpose for longer run.

A $20,000 EV sounds good, I assume having a shorter than 300-mile/charge range. Well, 7-8 percent battery improvement per year ain't much, but we'll take it!

A better solution than batteries would be road-embedded electromagnetic propulsion. This would provide a linear motor powered directly from the grid.

We are no where near a tipping point! Lithium batteries lose 25% of their capacity per year. That's 300, 225, 150, 75, 0 miles range after 4 years and the car is not worth putting a new battery in. As lovely a dream as EVs are, they are far, far from a practical option. They are a Marie Antoinette solution. If people have no bread to eat, let them eat cake!

Some of the new developments in lead/acid may be practical for short range EVs.

Is the capacity loss year really that high? I've never heard 25% per year. Looking around on the web, the numbers I see are lower than that. Still, your point about capacity loss being an issue, even if it's not 25%, is relevant I think.

$20,000 sounds better than $30,000, but it sounds like around $30,000 is hope for the low price for the third-generation models. And yes, I am sure for the low-end model the range won't be 300 miles per charge. Even the pricing on the Model S covers quite a broad range, starting at $50,000 but going all the way up to about $90,000, I believe. And the biggest factor in the price differention is battery packs and range.

Didn't Fisker just recall ALL their cars to replace the batteries? Seems like the technology still has a way to go before it is a practical and economic alternative for the mass market.

EV is not exactly taking off, despite mass-market offerings and large subsidies: http://www.plugincars.com/chevy-volt-sales-sizzle-nissan-leaf-cools-february-2012-113480.html The article's author is a clear supporter of EV, but the numbers defy the optimism. It is a niche market, and likely will remain that way without some fundamental change in technology. As to the suggestions of using large banks of improved lead-acid batteries in EV, that seems like an entirely predictable environmental catastrophe, especially in second and third world countries.

Great, I've got a new EV that doesn't use fossil fuels. Wait a minute, where am I getting the E for my new EV? OOHHH! from fossil fuels! Without clean E, EV's are a waste of time and a mirage to the ever existing fossil fuel problem. Are we all that stupid that we can't see the whole picture instead of just one tiny piece of it? Cars are not the problem. Clean and safe energy generation is the problem. Without clean and safe energy generation we are all fooling ourselves that EV's are going to save the world.
