Somebody told me that to get the pure hydrogen, you have to use fossil fuels, so if that right, it doesn't really help us out much...
plus if you crash....boom...
I found more about what you're talking about:
Hydrogen can be produced using a variety of domestic energy resources - fossil fuels, such as coal and natural gas, with carbon capture and sequestration; renewables, such as biomass, and renewable energy technologies, including solar, wind, geothermal, and hydropower; and nuclear power. Specific technologies and processes are described below. Thermochemical Processes
* Steam methane reforming: In this process, high-temperature steam is used to extract hydrogen from a methane source such as natural gas. This is the most common method of producing hydrogen; about 95 percent of the hydrogen we use today in the United States is produced using this process. * Partial oxidation: Scientists are exploring a process that produces hydrogen by simultaneously separating oxygen from air and partially oxidizing methane. * Other thermal processes: Other processes include (1) splitting water using heat from a solar concentrator, and (2) gasifying or burning biomass (i.e., biological material, such as plants or agricultural waste) to generate a bio-oil or gas, which is then reformed to produce hydrogen.
* Electrolysis: In electrolysis, electricity is used to separate water (H2O) into hydrogen and oxygen. Current electrolysis systems are very energy intensive. The challenge is to develop low cost and more energy efficient electrolysis technologies.
* Photolytic methods: In photolysis, sunlight is used to split water. Two photolytic processes are being explored: (1) photobiological methods, in which microbes, when exposed to sunlight, split water to produce hydrogen, and (2) photoelectrolysis, in which semi-conductors, when exposed to sunlight and submersed in water, generate enough electricity to produce hydrogen by splitting the water.
Taken from this site: http://www.eere.energy.gov/hydrogenandf ... rogen.html, which has quite a bit of good information. It sounds like transportation, storage, and price are the main hold ups right now. If oil prices keep rising, that will leave transportation and storage.
Sweet, thanks Slomo, it's nice to know there are otherways to get it aside from using the non-renewable stuff! Hopefully they can get past the hold ups...

I believe you're right, but it is my understanding that the surge in demand has little to do with the car driver and more to do with the power consumer. I've heard admittedly unsubstantiated claims that the real increase in oil consumption is coming from a conversion from coal power plants to oil power plants.
Of course, they burn natural gas, so that might be the story for winter heating costs...
Mookie's right. What we're seeing is a shift in the demand curve, as shown above. The prices have to rise to get at economic equilibrium. Otherwise, there would be a shortage.
Now if we could just start drilling in Alaska, we could shift the supply curve to the right to help even things out...
And then in 15 years, we'd be right back where we started, and OPEC would still have us by the balls. The REAL answer is alternative energy, and decreasing our oil dependency.
15 years * 12 months * X gallons/month * $0.50/gallon = Drill in Alaska and anywhere else necessary.
I'll take the 15 years of cheaper prices, and when they do start to go up again, there will be more, cheaper options at the hybrid/hydrogen level so that I can keep my relative cost of consumption at a similar level.
Keep in mind that there is already a hydrogen gas station in D.C. Anyone know what the price is on that stuff?
