...three basic particles of antimatter—positron, antiproton and antineutron—share the same masses and magnitudes of charge as those of their counterparts in matter—electron, proton and neutron, but with opposite charges. Just as a proton and electron compose a hydrogen atom, an antiproton and positron make an antihydrogen atom. When matter and antimatter particles collide, they destroy each other in a burst of energy...

...with gasoline at $1.50 per gal. Gas prices are up 30% since then, but GM officials insist their strategy has not changed. The focus is still on delivering hybrid versions of SUVs and pickups while devoting the bulk of GM's future-power-train research into a commercially viable hydrogen-fuel-cell vehicle, which the company says is on track for 2010. (Ford was slow, too, having to license some technology from Toyota for its hybrid Escape...
...brands. The Big Three--Ford, GM and Chrysler--are even more reliant on SUVs and big pickups for profits, and if hybrids eat into sales of conventional models, the industry would be maiming a critical cash cow. So while auto executives talk of a greener future of hybrids and hydrogen-fuel-cell vehicles, they continue luring customers to gas guzzlers loaded with powerful engines, luxury amenities and gadgetry and moving them off the lot with generous incentives...
