What if we spent $220 billion on things like this?

This AP story talks about the opening of the first hydrogen fueling station in the US:

About four miles east of the U.S. Capitol, in an industrial section of town, sits a gas station that looks like any other. But it's not, because on Wednesday it became the first in North America to have a hydrogen dispensing pump.

Shell executives, Energy Secretary Spencer Abraham and District of Columbia Mayor Anthony A. Williams unveiled the technology, which the Bush administration hopes will help reduce the country's dependence on imported oil.

'This will be, in fact, the first step toward the real transition in the economy from the carbon-based economies of the past to a hydrogen economy of the future,' Abraham said.

So let me get this right. The Bush administration thinks that this is a way to get us off foreign oil, but spent the $220 billion in Iraq anyway. What if we had spent the $220 billion in the war in Iraq on things like this instead? How much farther along would we be in ending our dependence on foreign oil? Now if that's liberal thinking and not the ultimate conservative position, call me a crazy liberal.
