This is what Bush said today about inventing cars that doesn't need oil anymore:
Tonight I'm proposing $1.2 billion in research funding so that America can lead the world in developing clean, hydrogen-powered automobiles.
A simple chemical reaction between hydrogen and oxygen generates energy, which can be used to power a car, producing only water, not exhaust fumes.
With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom, so that the first car driven by a child born today could be powered by hydrogen, and pollution-free.
Join me in this important innovation to make our air significantly cleaner, and our country much less dependent on foreign sources of energy.
