I wouldn't recommend holding my breath for any great new technology to come rolling down the pike and displace gasoline in the next ten years. You will see greater availability of biodiesel. You will see improved hybrids and AC rechargeable cars for people who never leave town or don't mind stopping every night while travelling. You will see more cars fueled by propane or natural gas. But everything you see will be simply an improvement on existing technology, as we are many, many years from any major breakthroughs in finding a replacement for gasoline and the good ol' internal combustion engine. Ten years from now, you'll still be able to pull into an Exxon station and pump gasoline into your tank.
