Now Playing at Reason.tv: McCain's Big Cash Prize!
July 24, 2008, 2:56pm
Paying $4 for a gallon of gas is a drag, but what may be worse is listening to White House wannabes who promise to rescue us from our misery.
Take Senator McCain’s recent proposal to offer a $300 million cash prize to the inventor of a car battery that can out-green 100-mpg plug-in hybrids. Is McCain’s money pile really necessary to spur our nation’s geniuses to get it together and invent an ultra-efficient car? reason.tv’s Ted Balaker thinks not.

Hardly a bad idea. To quote Jerry Pournelle:

>Prizes reduce market uncertainties by providing a floor.

The properties of batteries used for EVs -- capacity, useful life, energy-to-weight ratio, and cost, being key -- are indeed the most critical issue for that type of transportation right now, so I think it is proper for McCain to be focused on it. If there were a 500 lb. module that would hold 100kWh or so, could be purchased for $1000-2000, and would last for at least 1000 recharges, that would be enough sufficiently inexpensive energy storage, for example, to let me convert my 2004 Ford Taurus to EV and get good range and excellent performance out of it for the next 10-15 years, even without optimizing body weight, tires, and several other factors. An optimied EV sedan, such as proposed by Tesla and others for near-future production, would be able to travel much farther and hold more passengers and cargo, using the same battery pack. But today, we typically have energy storage units that can store only 50kWh or less. They weigh-in at 900 lbs., or more. Their energy capacities are enough to propel the highly weight- and- friction-optimized, 2-seat Tesla roadster at highway speeds for a little over 200 miles per charge. The purchase/replacement cost for these energy storage units is daunting: it's been estimated at $10,000 or more, which the motorist will be guaranteed to spend after every 100,000 miles or so (that is to say, the battery pack alone costs 10 cents per mile, apart from the cost of the electricity, which depends on your price per kWh -- on average the Tesla travels 4-5 kWh for every kilowatt-hour of energy consumed).
Lacking an inexpensive, lightweight, long-lived, hardy, high-capacity battery, EV designers have to be clever (in many cases, miserly) with weight, rolling friction, aerodynamic drag, heat dissipation, etc. This necessity drives design and production costs way up, and precludes many ICE-to-EV conversion efforts (my Taurus, for example, which would require an infeasibly large and heavy battery pack to get around the vehicle's inherent level of friction, aerodynamic drag, and weight).
Maybe it is unwise to pay attention only to one vehicle component. But if you can/will only pay attention to one, I think the battery must be it. The people who are putting words in McCain's mouth are right about this one, I think.
