WOW! Lots to reply to!
I have to admit, I know nothing of commodities, or commodity exchanges. And I personally think it's all a huge scam anyways from, all accounts.
As for the use of gasoline/ethanol: What's assisnine is people who promote the production of ethanol from corn. As you said, corn is incredibly inefficient to use. Instead of corn, there's a type of grass, called switchgrass, that is HIGHLY HIGHLY HIGHLY effective.
Corn requires very careful care, and maintenance. So much so, that the land that is needed to grow it is actually incredibly valuable. Whereas switchgrass can pretty much be grown ANYWHERE. Now what type of land in this country is not being utilized at all, in which there are literally millions of square acreage that could be used for one crop, and only one crop, called switchgrass? That land would happen to reside along all the highways of America. Well, mostly the eastcoast highways, in which both side of the highway is mostly open grassy areas as it is. No farmer would be able to grow corn, even if he was allowed to, along these loooong stretches of un-utilized land.
Switch grass has proven to also yield a much higher return of energy, per acre, than corn

http://bioenergy.ornl.gov/papers/misc/switgrs.html "Test plots of switchgrass at Auburn University have produced up to 15 tons of dry biomass per acre, and five- year yields average 11.5 tons—enough to make 1,150 gallons of ethanol per acre each year."
There are soooo many more benefits on this article that I care to list here. The one I sited above was the one that stuck out the most. This grass could be grown almost virtually anywhere in the continental US. NOT true for corn. In other words, the good plots of land would be reserved for corn, soybeans, and many other types of food vegetation. So there would not be the conflict of "guns or butter" so to speak, in this case.
And yes, the reason why I'm glad to see the American auto-makers going broke is for the reason you stated: they refused to do R&D on alternative fuels. They deserve to go under. Not that it's beneficial to us, but I'm hoping when they finally do, it'll be a wake-up call for all the other industries. The reason Toyota, Mazda, and other foreign manufacturers are doing so well, is because they didn't sell out to the oil industry, and have instead, been doing extensive R&D into better fuel-economy cars. Case-in-point: A local technical school in my town, Pennsylvania College of technology, is one of the the premiere tech schools in the state, has been working extensively with Toyota. Toyota donates 2 or 3 alternative-fuel cars a year to the school, so the students can learn the ins-and-outs of how the engine is designed.
As quoted from:
http://www.pct.edu/schools/tt/bau/ "The automobile industry's future, of keen interest to the automotive teachers mentoring tomorrow's vehicle technicians, is today's reality at Penn College. The North American Council of Automotive Instructors, holding its 35th annual conference on campus, heard presentations Tuesday on vehicles that use technology to reduce petroleum dependency and greenhouse-gas emissions. Toyota brought along a prototype fuel-cell vehicle, which attracted considerable attention (and some willing test-drivers) from attendees and the media alike. Also on hand was The Pennsylvania State University's EcoCAR research vehicle, which gives engineering students the opportunity to design and build cars that demonstrate leading-edge technologies, with the goal of minimizing the environmental impact of personal transportation. Among the visitors was WNEP's Norm Jones, whose report on the Toyota vehicle aired at 5:30 Tuesday evening. Additional coverage, including his interviews with conference organizers and attendees, tentatively was to broadcast later in the day. The Williamsport Sun-Gazette also published an article about the car on the front page of Wednesday's editions."
Another switch of topic: The whole idea of other nations setting up oil rigs right off our shores and we are not aloud to do the same, is laughable. As I said in another thread somewhere, all the interest groups in the US, have more rights than the majority. THAT is laughable as well, and downright infuriating. Which is why I was so upset over the opposition to wind-mills. (Nuclear power kinda scares me a bit. Nobody is still allowed to step foot on three-mile-island down in Harrisburgh, which just a 2 hour drive away form where I live. Berwick is the closest I live to a nuke plant, and is only 45 minutes away. The opposition to nuke power is quite understandable, considering the high-risk they involve.) The wind farm proposal is situated on a tree-less plateu (spelling?) in the north-east corner of Lycoming county. There are plenty of wind sheers up there. And considering the county population is pretty sparse, the wind-mill WOULD put a dent in energy costs in this region. And since local taxes would support the mill, it would not have to be put on the National Grid. It would still help the Grid, by taking 100,000 households or so off of it at some points throughout the year. Especially throughout the fall and winter months.
Geothermal energy: The entire West Coast of the US is full of hypothermal vents. Sure, it may not do much directly for us inthe East, but California is notorious for brownouts. The East...indeed, the entire nation, would benefit for the reduced dependance on oil. I know I read somewhere there was serious talk about contructing geothermal stations up in Washington state, and one in Hawaii.
The East coast has many, in fact, it is full, of rivers and their tributaries. granted, they could effect the wildlife, particularly the fishing migrations, above the dam, but ecosystems have been known to adapt to, and change around the damn. Indeed, life is incredibly resilient that way. If it wasn't we would not even be here discussing this right now, if you think about it. There is only 1 major hydroelectric dam on the East Coast that I can think of, and that's up in Buffalo. Canada gets half the electricity from that dam. There are a bunch in Tennessee, I am sure, from the TVA project back during the Great Depression, which i think is still around. I'm not terribly sure about that though. someone can correct me if I'm wrong here.
Solar Power: like you said Zetetic, would only be effective in Arizona, and CA (actually, NM, TX, and all them other Southwestern states would benefit form it just as well). However, if we could take THOSE states off the Grid by insituting solar panel electricity throughout that region, it would reduce our dependance on fossil fuels by at least 1/4, if not more, without the construction of more nuke plants. Plus, also, like you said, the UK is developing a wave-powered source of electricity, the US should be doing the same. Hell, we got more mileage of coast land than any other nation on the entire globe. OF COURSE we would benefit HUGELY from such a technology, and WHY are WE not devloping such a technology? The Gulf Stream alone could produce millions, if not billions, of kwh.
I guess to sum it all up, it isn't just 1 source of green technology that should be used, its a combination of some, or ALL of these technologies. My first example of a wind farm was just that, an example. The example would reduce the dependancy of my small little county that I live in. Yes, it's just one little population out of 300 million, but if ALL these small little populations throughout the nation were to do some small little green contribution like this, then the US could be more like Brazil, or Iceland. We wouldn't have to worry about oil, and the Middle East would be worthless to us. As it should be right now, but isn't because of these greedy, selfish corporate commodity types. Little do they know, if this keeps up the way it's going, they will begin to lose out as well in the end.
*Deep Breath!*
Zetetic, it would be awesome if I did end up selling a soda to ya back then. Although in 1996 I believe I got "promoted" to selling programs instead hehe.
