GM is betting their company on the Chevy Volt. It’s a plug-in electric hybrid supposedly due in 2010. But reports are it will be late and the battery, which they are inventing as they design the car, remains a huge problem. It doesn’t exist yet and if and when it does, will probably be extremely expensive.
Engineers at Toyota have all plug-in hybrids, including the Volt, on “death watch” because the batteries will be too costly. They also think that trying to get people to charge EVs at night won’t work. So massive amounts of new solar power will be needed.
One also wonders if GM will survive in its current form until 2010, much less beyond.
