What no EVcast Link? http://www.teslamotors.com/blog2/ How many of those sites feature the first Telsa Prat fall? http://www.evcast.com/members/evcast/videos/VIEW/00000059/Bo-and-Ryans-Tesla-Testdrive.html

Live show followup:
I should be called a quasi-live listener because after listening to the pod cast I realize that my wife is actually right, I don't listen. Nevertheless here are some followup pointers.
Here's the photo of Doug http://www.autobloggreen.com/photos/tesla-model-s-live-reveal/1455054/.
Doug, link where you post your stuff. Good job on the report, but somehow I don't think we heard the whole party story. Was the physicist Micho Kaku? I hate spelling.
Mr. Granville may have a great product but my scamdar went off. Maybe it was a foreshadow of marketing hype that seemed desperate, e.g. tesla 300 mile range baiting. Sorry I still think Nimh will be cheaper per pound of storage kw. Look at how the cost has dropped in the last couple years for nimh and they are not generically produced yet.
Feed back callers when you take your preshow drugs please make sure they include an upper. The evcast deserves better. Low energy ultimately may cost you your stage time. Good content iffy presentation.
BTW I never really heard of Chelsea Sexton before the EVcast so maybe she should give the cast a break.

$1000/Kwh for Lithium Ion batteries?
Really? Someone tell Thundersky because you can buy their batteries for
$140/(3.2V * 90 A) = $486 Kwh

I was able to dig up great video on the model S sedan. Enjoy.

How would I calculate the KWh cost of this one? Excuse the ignorance. Maybe dag you show the whole calculation. I am sure someone knows the cost of these?

That pack is 12V pack and has 80Ah of capacity. So you just multiply 12v * 80 Ah = 960Wh = 0.96 kWh. So the price of that pack is roughly the cost per kWh (if you want to be more accurate just divide the cost number by 0.96 to get cost per kWh). I don't think they specify price anywhere on there so I can't immediately get the number.
The guest above me has it correct . . . the battery has 0.96Kwh of energy storage capacity but you need to find a price for that NiMH battery in order to calculate its price per Kwh.
The Axion lead-carbon batteries look interesting but it is annoying how they constantly poo-poo Lithium-Ion technology batteries with exagerrated high prices, claims of Lithium scarcity (there is more lithium on the planet than lead), and over-stating the danger of Li-Ions by conflating problems with the old Lithium-Cobalt batteries instead of the current LiFePO4s, Li-Mangesium, or Li-Titanium batteries.
The lead-carbon batteries will not be as energy dense since they still used lead for one plate but their longevity capability is very interesting. They just need to crank up more factories and get their damn batteries out on the market so people can buy them & test them.
It is hard to get good data on automotive Lithium Ions but between retail prices on the web for LiFePO4s, statements from Enerdel, and statements from GM; a good guess is that they are less than $500/Kwh in volume production. (Which is at least 1/2 what the Axion guy said.)
Perhaps the Dept. of Energy should buy the Nimh patent from Chevron.

If anyone has a link to the $/KWH information on batteries, I would appreciate seeing it.
OK, something is really wrong with the quoted battery prices. I can purchase both NiMH and Li-Ion batteries at the consumer level with prices less that $1000/KWH.
NiMH batteries have been around for quite some time in AA format. Without a sale, these can be purchased for $2.50 each, which translates into $1000/KWH at the consumer level.
AANiMH price $2.50 V 1.25 mAh 2000 Wh 2.5 KWH 0.0025 $/kwh $1,000
I did some looking for Li-Ion batteries (not really a consumer product) and found that a standard form is the 18650 shape. These batteries can be purchased in volume for $6.00 each which works out to be $676/KWH.
http://www.batteryjunction.com/tenergy-18650-tab-2600.html
18650 Li-Ion price $6.00 V 3.7 mAh 2400 Wh 8.88 KWH 0.00888 $/kwh $676
If I use ebay prices, I can get them even lower. If this analysis is reasonable, I would expect GM pricing to be $500/KWH. However, they might need to add more costs for the heating and cooling systems for the batteries.

I listened to the end of Episode 25 with Chelsea and didn't hear any problems.
Also, no problem with Episode 163. Are there other times she has been on the show?
