While at the Detroit Auto Show I had the chance to meet GM's CEO Rick Wagoner in a group discussion with about ten journalists. It sort of reminded me of the film Roger and Me, here I am some bumbling Michael Moore-type winding my way through months of effort to finally stand next to GM's CEO, although in my case I was actually invited to do so.We each had the chance to ask one question. Here's how mine went:Thank you.Lets face it for a while you have to look at it as investment in the future and we spend R&D money every year and we spend on advanced engineering and advanced design. I think in the very early stages you have to recognize that you have to invest and sometimes the investment cost is higher than the market will bear.Obviously were hoping for and we will get some good government incentives to consumers for products like the Volt which will help to cover some of that cost shortfall. The other thing is we have to work like crazy to get the cost down. This is where if the EV market in the US grows very gradually it makes the risk of it being unsuccessful much greater than if it can grow rapidly. If it grows rapidly you will see the suppliers investing and people putting R&D into the next generation technology, improving the manufacturing processes and being able to get the costs of the battery down much faster. This is where proactive government policy in this area will make all the difference.There's a reason today why most of all of those lithium batteries that we use in our cellphones and computers come from Japan. Its that when it wasn't financially viable for private enterprise (to manufacture them), their governments were supporting it 15 or 20 years ago. We need to recognize in certain areas that proactive government engagement, clear directional policy, and in some cases support for R&D is going to be critical to move towards energy independence and leadership in battery technology.Wouldn't it be a shame to go to this massive effort to shift reliance from oil to diversifying the use of batteries, and we wind up having to buy our batteries from somewhere else.
