On Alternative Fuels. Today in thermodynamics (on one of the rare occasions I'm actually paying
attention), the professor was talking about the concept of efficiencies. And as a supplement to the lesson, he brought up the topic of automobile well-to-wheel efficiency. He showed us results from a study on alternative fuel options (featured in "Mechanical Engineering Power 2003"), and long story short:
hybrid vehicles are a lot more viable than fuel cells (from both the economic and engineering standpoints).
There's a lot of hype surrounding fuel cells because the reaction at the heart of it is like: 2H
2 + O
2 -> 2H
2O +(energy). But the part that most people
don't know about is where that H
2 comes from. It's not just like,
hey, let's grab some H2 out of the air! Yea, you either gotta zap it out of water through electrolysis (which requires other energy), or they gotta make it out of hydrocarbons (i.e. fossil fuels), so truth be told, it's
not truly a pollution-free process. And plus, to distribute the hydrogen necessary to pull this whole thing off would require almost into the trillions for infrastructure (by the estimate of the article I read). So yea, fuel cell vehicles probably aren't gonna be prominent for several more decades, at
least.
The Politics of Energy. Yet Bush is pushing for fuel cell vehicles and got some props from environmentalists for it too. But the lesser told story is that funding was diverted from hybrid technology to fuel cell technology. I tend to believe that this was meant in some way
to help the oil industry. Dump money into a fuel technology that's not gonna show results for a long time to come, to keep the cars dependent on oil. And also, remember that bill in congress this past year to raise the
fuel economy that didn't pass? Fuel economy regulations haven't been changed since the 80's, even though the technology exists today to raise the mpg a hefty bit and do it cheaply. I can't help but think that that's the work of oil industry lobbyists as well. Opposition to raising fuel economy standards often decry the loss of automotive power in doing so, but hybrid technology can increase power as well as mpg. And also, what is the deal with
ethanol? You know, that fuel substitute made out of corn? It's both less powerful and more polluting than gasoline (*edit: depends who you ask), yet year after year the government dumps funding into it- obviously to get the support of Midwestern states by appeasing the corn farmers.
But anyways, back to the oil industry. Let's talk about the war in Iraq. Only in the past couple months has it become evident that WMD's were not a real reason to go to war at all. Now, I
never really thought that was what the
war was about, but I read an article maybe half a year ago that I found particularly interesting. It pointed out that on the global market, oil is traded in American dollars- and this is supposed to give us a hefty bit of financial leverage somehow (don't ask me, my understanding of economics is shaky at best). Anyways, immediately prior to the war, Iraq decides that it wants to start trading in the increasingly popular Euro. Lest other nations should follow suit, we bomb the hell out of and invade Iraq, and lo and behold, Iraq trades oil in American dollars again. Heh, that'll teach
them- let's see if any
other OPEC countries wanna try pulling the switch to Euros, heheh. (*edit: haven't found other sources corroborating this theory, so dunno how true it is, but
I still believe it.)
But yea, there's always talk that we're gonna exhaust the global supply of oil in the next couple decades. I dunno, seems like they keep pushing back their guess of when that's supposed to happen. But I mean, CO
2 and other greenhouse gases too. It's my belief that global warming is no joke- it's happening, and it's happening cuz of us. Now, I don't think it's gonna be as drastic as the trailer for that "Day After Tomorrow" movie or whatever, but I can't forsee anything good coming out of it. Yea... something to keep an eye on I suppose.
