More On KERS

From this article by the UK's Guardian:

"'It's nonsense,' said one team engineer. 'We're saving costs with the engines - which is fine. But some of the larger teams are reputedly spending $70m [£35.5m] on Kers in the hope that they will find a performance advantage. It means even the smallest teams have to look at spending between $5m-10m they don't have. One of the Kers systems uses batteries to store the energy. They cost £150,000 and would need to be thrown away after each race. Where's the sense in that? But we're stuck with it for as long as Mosley is in charge.'"

And we're trying to save costs right Max?
