I have found another much earlier one citing a Cornell and Berkley study that is from 2005. They only count the final fuel as a useful output, and their conclusions are much worse than any of the studies I remember.

And for balance a reposte from NREL, USDA and DOE that is notable mainly for the huge number of typographical errors in the webpage.

I think in the USA this may be true, but in the ROW most people could see that the US fixation on corn to ethanol as biofuel was misguided. Even some notable US right wing chemists like Uncle Al posting as far back as 2001 could see this. See for example:

I know who I believe on this one.

They never ask the scientists. Like the hydrogen economy it is the promise of jam tommorrow.
I think US Bioethanol was mainly a disaster wrought by politicians.
I do incidentally agree with you that some US environmentalists are a part of the problem rather than a part of the solution.
All true. Though you really want a secondhand relic of a diesel if you are going to put DIY manufactured biofuel into it. Because of the high fuel prices tests for red diesel (cheaper agricultural use only) on the roadside have become a lot more frequent.
Some of the heathrobinson setups for DIY biodiesel fuel conversion I have seen on alternative lifestyle TV shows were truly deadly. People with no idea of what they were boilig up old cooking oil with reagents which could in the wrong combinations would quite easily dissolve flesh. And if not neutralised correctly at the end would dissolve some engine blocks!
It has made growing oilseed rape a lot more attractive. I used to think it was an EEC designated crop simply because it was easy to monitor planting by satellite. Horrible stuff to walk through when mature.
It is still pretty iffy. Although there is nothing wrong with taking waste oil streams and using them in diesel engines if they are not fit for anything else.
Uranium 235 has a half-life of 703,800,000 year. It's fission products have much shorter half lives, and even the longer-lived products have half lives of a few hundred thousand years.
In the long term you are right, but we are more interested in the short term, where mining and fissioning uranium concentrates a few million years of radioactive decay into a period that is a number of orders of magnitude shorter.
By the time the short term boost to the background radioactivity has decayed to the point that the reduction in the long term radiation load is visible, we could expect to be extinct.
A couple of years ago, the wife and I took a Caribbean cruise. Twice, our ship stopped for Cubans on makeshift floating objects. Although our crew tried to convince the Cubans to come aboard to safety, they all preferred their rafts. Coming aboard would have meant their ultimate return to Cuba.
I will never forget that situation: Us on our ship with *everything*; them on their raft with *nothing* (perhaps not even their lives). We did not want aboard their raft, they did not want aboard our ship. What was the barrier between us? Politics!
A few days later, Hurricane Wilma swept through that area and likely made fish food out of some of those poor people.
I know a chinese guy who has had the same sourdough batch in his family for over 100 years. Whatever few bacteria were the original non-flour-non-water-non-salt ingredients, they must be parts per trillion now, if that. Nothing else has been added for thousands of dilutions, sort of like homeopathic medicines.
And the culture changes with time and how you treat it. Sourdough afficianados take pains to cultivate distinct qualities, then guard 'em like treasure. (Which is what they are.) I've encouraged mine to become wickedly sour, the way I like it. Great toasted, but I usually just rip chunks off the loaf.
Mmmmm. I'm fasting today, and this talk of sourdough and choclate isn't helping.
James Arthur wrote in news:SZygk.164$5Q.85@trnddc06:
I was speaking generall. "Conservatives" *do* use "Al Gore" to mean anyone who has any concerns about the environemnt.
Heard none here? Or what? Didn't hear on teevee or read in the media, or heard Gore talk abut? I've been against corn-derived ethanol ever since I heard people blithering about it. So what - who am I? - just on single paltry insignificant citizen, not any media darling and not a billionaire (or even a millionaire) and nto a politician - so is Gore, or any other politician, going to listen to me, or include my comments in their media events? Hell, no. IOW, of course you would never have 'heard' *my* objections to basically dumping corn into SUV gas tanks.
I have no idea whether Gore is "in tune with environmental-types"; I have serious and numerous concerns (and no, "concern" is not a synonym for "iron-clad ideology"), but I don't think that makes me an "environmental- type", because I am not anti-business - I think it merely makes me someone who looks further than my own nose, and is worried about the future of life on this planet. There are a lot of folks like that, who aren't 'heard', becasue they aren't a majority, and not a "squeaky wheel" minority.
More likely? Well, sure, why not - after all, I don't know anything about "the flow", I have a glitch in the part(s) of the brain that deal with social 'instincts' and I never have been able figure out squat about "the flow", other than that I've consistently heard ideas being talked about an average of 15 to 20 years after I've started thinking about them. So Gore probably *is* "going with the flow", soemthing I never have been ableot learn to do - which is why he is a rich politician, and I'm not.
Anyway, again, I was speaking generally.
I don't particualrly think it matters a whole lot. Whatever the articles, teh fact is that the idea of using ethanol as a fuel is *old*, not new. I think, and have long thought, that using *food crops* to fuel cars, esp. ones which are wontonly wasteful, is a stupid idea. I know other poeple who are have also thought that for a long time.
And you're right, we were, and are, irrelevant.
Convenient, since I was pointing out that Gore is not "all people with environmental concerns".
You're right:
- saying that people in general need to adopt a more postive attitude and clean up their individual acts, rather than relying on someone else to solve their problem, *is* ineffective, becasue it's so much easier to pass the buck;
- protesting extremist party chauvinism *is* ineffective, because too many people like the simplicity of it; trying to separate general principles from party chauvinism *is* ineffective;
- and my ideas *are* irrelevant, because none of them can/will ever make any damn difference - you yourself say you haven't 'heard' objections to this or that idea of his from "environemntal types", yet ignore or reject, and snip, the objections someone does mention, which well illustrates the irrelevance of what I was trying to say. Yes, sorry to have been so rude as to talk about my own objections to ideas like fuel ethanol from food crops, and my own environmental concerns, and reasons for those concerns. And sorry for my irrelevant posts about switchgrass in connection with teh topic of fuel ethanol.
I wasnt' paying attention to who wrote the post; I was excrutiatingly clear to say "too many people", and simuilar statements - I did *not* say "all people" and did not point to any specific person. I guess my point was far too obtuse.
Sorry to have interrupted the Gore:corn-ethanol hair-splitting. Please continue.
Actually you would want any Offsite Heat to be from a Heat Exchanger, that was removed from the Primary Coolant Loop by at least two stages. This allows for a Primary Heat Exchanger leak from one side to the other, without any radiation leaving the Plant, via a cross contamination. Usually the secondary side of the Primary Heat Exchanger is what drives the Turbine that produces electricity, and any Primary Heat Exchanger leak would put some contamination into the Turbine Loop, which has Radiation Detectors looking for just this type of leak, and if it is Detected, Scram's the Plant.
Obese people have been mocked and discriminated against for too long. I'm hunger-striking for a person's right to be fat, and I invite obese people the world over to join in. We won't quit 'til we win.
Good point. There are places in Alaska where you could plop the entire Netherlands without anybody noticing for a few years. Hell, Alaska is more than 3 times the size of France. Even dinky little Texas is bigger than France. California is almost 2x the size of the UK.
I spent some time in Juneau; nice old mining town.
I spent a little over a year, near Delta Junction.
