Presidential candidate John McCain (R-Old) is expected to unveil a new proposal today offering $300 million in prize money to the first automaker that can demonstrate significant improvements in battery technology.

Additionally, McCain announced a "Clean Car Challenge," offering U.S. automakers a $5,000 tax credit for every zero-carbon-emissions car developed and sold. Apparently, McCain thinks the market's delivery on a 100-mile-per-charge battery won't be coming as he predicted without some helpful handouts incentives.
