So, John McCain has proposed paying a bunch of money to someone who can come up with a "revolutionary battery" to free us from oil dependence for transportation.
Here's what I'm thinking. The "revolutionary" batter may not exist. The "evolutionary" improvement in battery tech is happening even as we speak. If my idea was to happen, market competition would surely result in continual improvements. But here's my idea:
STANDARDIZATION
If the auto industry were to get their best brains together, and agree on a basic size, shape, and interface for a standardized electric car battery, then gas stations could simply be converted into "battery exchanges". You pull into the station, pay whatever the cost would be, and they take your battery out, put a freshly charged one in, and you go on your merry way. They plug your battery into a rack to charge, and use FIFO (first in, first out).
They could then install PV and wind turbines on all these stations to offset what they suck out of the grid, and increase profitability.
The initial design agreed upon would have to be WELL thought out, of course. And the range of the battery would have to be close to what a tank of gas will get you. Or they'd simply have to build more stations in the boonies where existing gas stations are too far apart.
Competition will lead to improved models of this standardized battery. This might lead to "regular" vs. "premium" batteries as well. Or if you have a premium battery, and the station doesn't have enough fully charged premium ones available, then you'd get your regular battery at a lower rate. You could "upgrade" whenever you wanted by paying a similar difference in reverse.
What do you guys think?
