Ofcourse, the big news out of the GigaOm interview with Musk is the Model X reveal. But here is something interesting. I've been thinking for sometime that the battery price will halve every 5 years. We had some discussions about it in a different thread.

The difference between selling S & Roadster is roughly 4 1/2 years (Feb-2008 to Jul-2012). Musk says the cost actually decreased by more than 50%. Ofcourse, it is possible he is comparing the cost now to something much earlier than Feb-2008. Still, this is instructive.I think we’ll also see steady improvements in battery technology. In the case of the Model S, it’s less than half the cost per kilowatt hour of the Roadster. So we’ve made a huge improvement there and the range has increased and the efficiency has improved. I think we’ll continue to see an improvement in the cost in battery energy maybe 7 to 9 percent per year. That may not sound like a lot, but if you compound that over several years it becomes very significant.
If we take his 9% per year cost reduction, we get to 38% reduction in 5 years.
