Pumped Up

Gas prices keep going up and up, and all the government can do is tell us that we have to set up oil drills in wildlife refuges - but that’s OK because animals actually like oil drills. While that debate goes on, I wonder why we’re still using gas in the first place. Is there some reason that here in the 21^st century our primary modes of transportation are based on 19^th century technology? Surely it’s time we found something more efficient than the internal combustion engine. I’m thinking personal, miniature blimps here.
