Liquid Coal, Hitler's Fuel!

Byoliveridley

Congress weighs coal fuels, carbon questions linger – Apr. 23, 2007

The technology, developed in coal-rich Germany in the 1920s and used heavily by the Nazis in World War II, involves partly burning coal to turn it into a gas, then using a catalyst, usually a metal, to make it a liquid.

The basic premise of liquid coal (using the wonderful Fischer-Tropsch Reaction) is that “plentiful and easily available” coal is converted into diesel that can be used for automobiles. Liquid coal is yet another wonderful distraction in the quest for clean energy sources.

The attraction of using a plentiful domestic energy source is obvious. It would help cut our reliance on oil, about a quarter of which comes from the Middle East and Venezuela.

It also keeps money stateside, flowing to coal miners instead of countries with links to terrorists, which explains why the coalition’s members include several labor unions.

You mean, you willl do this to every coal mining town just so you don’t have to increase fuel efficiency by 25% and avoid “terrorist” oil? Jeez, and this casual assumption of “if we don’t buy their oil, terrorism will decrease”. Patriotism and blatant fear mongering can be used to sell anything, apparently. Coal mining is one of the most destructive and harmful operations you can imagine. Here’s a short summary (LINK)

It is difficult to explain the scope and impact of mountain top removal to people who have not seen it. Some sites cover three and four thousand acres. Millions of cubic feet of land are blasted away by explosive charge to get at the thin seams of coal underneath the mountain tops. Trees, rocks, soil-in short, everything but the coal-is considered “overburden.” Land is devastated, and afterwards the ground must be compacted so hard to stabilize it that nothing but scrub grasses will grow. Rains rush off the denuded mountain tops at an alarming rate.

Of course, like all other carbon rich fuel sources, carbon sequestration remains a must for any possibility that we can see a decrease in carbon emissions coupled to an increase in carbon fuel use.

Henry said that “carbon storage” – an untested technology where about half the carbon dioxide in coal is removed and injected underground – can make liquid coal so that it emits 60 percent less carbon dioxide than gasoline.

“This statement is total garbage,” said Pete Altman, coal campaign director at the National Environmental Trust, saying the study Henry was referring to compared a hybrid diesel engine to a gasoline engine

So we’re willing to go to greatly increased carbon emissions, devastated country side, increased water pollution, air pollution, mining deaths, etc. just so we don’t increase fuel efficiency by 25%? Wow, priorities!!

The bill is expected to make it to the Senate floor in the next few weeks, and both Democrat and Republican staffers say a Republican sponsored amendment allowing for liquid coal is likely.

Other bills provide loan guarantees for companies building coal-to-liquid plants, which typically cost $3 billion to $5 billion apiece, as well as guaranteed price support if oil falls below $40 a barrel.

It seems clear the industry needs government help to succeed. Lawmakers have to decide if they are willing to fund a fuel that appears to do little to cut greenhouse gases.

I am sure lawmakers will make it happen as long as their lobbyists want to make it happen, if it means subsidies, relaxation of pollution rules, and other such shenanigans, so be it.

Go Solar!.

Note: the blog Environmental Action follows the liquid coal story very closely and had a post on this very article. Reading this blog, you will find that the great savior Barack Obama is also a liquid coal acolyte (It’s that whole midwestern pandering to coal and ethanol!)

    Glass baby bottles making comeback

    Byoliveridley

    More Bisphenol A blowback, apparently, SF parents are switching to glass.

    Glass baby bottles making comeback / Stores selling out after health alarms raised about plastics

    Glass baby bottles, replaced decades ago by unbreakable plastic, are making such a comeback that parents can’t get their hands on them.

    Online and brick-and-mortar retailers report a run on glass baby bottles in recent weeks that they say was spurred by reports that the most common type of plastic in baby bottles may leach a toxic chemical.

    San Francisco resident Sean Mullins said he decided to switch his 6-month-old son, Mickey, from plastic to glass bottles last month despite manufacturers’ insistence that plastic bottles are safe.

    Independent tests done for The Chronicle and reported in November found bisphenol A, a chemical that mimics estrogen, in a baby bottle and several toys. Bisphenol A is also found in the lining of food cans, some anti-cavity sealants for teeth, and electronics.

    Watch for plastics manufacturers to fight back, this study ought to provide some ammo.

    Comparison of six samples of each of three brands of water available in both glass and polyethyelene terephthalate (PET(E)) showed that the waters bottled in glass contained approximately 57, 30, and 26 times more Pb due to leaching from the containers. Our study includes 25 brands of bottled water from Canada, and the median Pb concentration in these samples was 15.9 ng/L (n = 25), with a range from 2.1 to 268 ng/L. For comparison with the bottled waters, pristine groundwater from six artesian flows in southern Ontario, Canada, where some of the bottled waters originate, yielded a median concentration of 5.1 ng/L Pb (n = 18). In fact, all of the waters tested were well below the maximum allowable concentration established by the EU, Health Canada, and the WHO for Pb in drinking water (10000 ng/L).

    It all depends on which bolded sentence you chose to emphasize! So, glass bottles do leach some lead out, but nowhere near the amount needed to cause any effects whatsoever. I guess this is all the American Chemistry Council can come up with as a problem with glass.

    It’s irrefutable that glass can shatter, Hentges said. But there is “no scientific basis to conclude that BPA is something to be concerned about … at the extremely low levels that people might be exposed to from use of consumer products.”

    There is plenty of scientific basis to conclude that Bisphenol A has some very subtle effects at ambient doses. But science has never stopped the American Chemistry Council!

  • NC Phosphate Mine to expand: wetlands in trouble

    Byoliveridley

    newsobserver.com | Mine plan would erase wetlands

    The proposal by PCS Phosphate, if approved, would represent the single largest destruction of wetlands permitted in the state — 2,500 acres including the headwaters of seven creeks near the Pamlico River. The rich deposit of black phosphate rock, left by ancient oceans and buried 100 feet beneath the surface, has been extracted from the site by various companies for about 40 years. PCS has worked the mine since 1995 to get phosphate for fertilizer and for use in food additives. In food, it’s turned into phosphoric acid — a flavor enhancer in such products as Coca-Cola, jellies and vegetable oil.

    Yes, this is right, phosphoric acid is a “flavor enhancer”. Well, the mine employs a 1000 people in the area, and is not necessarily an evil that must be stopped at all times, for that, see Hog Factories! But this disturbs me.

    Hunter Turnage, 44, a Raleigh cable television salesman, has a house across the river from the PCS mine. He is one of several people who have written letters to the state complaining about the odor when the wind blows from the south.

    “If you don’t want to smell it, you shut up the windows and turn on the air conditioner,” Turnage said.
    “It’s something you just deal with. … I kept thinking one day they would run out of areas to mine. I think they’ll stay there forever –as long as they get continued rights to destroy the wetlands.”

    It’s one thing to use up wetlands, knowing fully well that the law requires you to create wetlands elsewhere to compensate, this smell issue is more problematic, and hard to legislate. Which means that various Environmental Justice issues will also come into play.

  • Drugs in the water: Behold the power of synergy

    Byoliveridley

    funky MathES&T Online News: Can drugs found in water harm humans?

    Researchers agree that aquatic species face the greatest risk from exposure to low levels of pharmaceuticals, such as synthetic hormones, which can act as endocrine disrupters at environmental levels. However, little is known about the potential human health effects arising from complex drug mixtures.

    Well, it is often more difficult to analyze complex mixtures because Experimental Design 101 makes you want to isolate the effects. And when you do compounds one by one in series, the tendency is to always add them up from the individual experiments. Unfortunately, body chemistry is not like that. I’ve always wanted to design a study that started complex and then tried to isolate later.

    To his surprise, Pomati observed that this mixture of drugs at environmental levels inhibited the growth of human embryonic kidney cells. After 48 hours of exposure, cell proliferation was reduced by 10–30% compared with controls. However, no inhibition was observed when cells were exposed to only the toxic cancer drug at environmental levels.

    Well, that seems conclusive enough, but here comes the “Experimental Design 101” Scold:

    The results show that the growth inhibition is not due to the single most cytotoxic compound alone. But that does not conclusively prove that synergistic or additive effects exist between drugs in the mixture, cautions Thomas Heberer of the Institute of Food Chemistry at the Technical University of Berlin. To show that the individual drugs behave additively, Heberer suggests that researchers should analyze the effects of compounds with a common mode of action, such as antibiotics, alone and in various mixtures.

    No, No, and No. Doing this presupposes that you know that mechanism of action, meaning you’ve half answered your question. The question Heberer is trying to answer is “do individual drugs with the same mode of action behave additively”. The question Pomati is trying to answer is “Can we demonstrate cytotoxic effects of a cocktail of drugs at ambient levels in a laboratory setting”? These are two completely different questions and Pomati’s question is more valuable at this point in time. Heberer’s strategy, on the other hand, will keep a lab well funded for years to come! But, it is very much the final step.

    It is more important at this point in time to demonstrate other effects such as endocrine disruption, mutagenicity, etc in the lab at environmentally relevant levels of mixtures. Then we can get a better handle on which  effects are relevant and which ones to ignore.

  • Solar plant cheaper than conventional plants

    Byoliveridley

    Generating clean electricity that's as cheap as power from fossil fuels is the Holy Grail of green-energy companies. A new solar project powering California homes appears to be closing in on that prize.

    Sempra Generation, a subsidiary of Sempra Energy in San Diego, just took the wraps off a 10-megawatt solar farm in Nevada. That's small by industry standards, enough to light just 6,400 homes. But the ramifications are potentially huge.

    A veteran analyst has calculated that the facility can produce power at a cost of 7.5 cents a kilowatt-hour, less than the 9-cent benchmark for conventional electricity.If that’s so, it marks a milestone that renewable fans have longed for: “grid parity,” in which electricity from the sun, wind or other green sources can meet or beat the price performance of such carbon-based fuels as coal and natural gas.

    via Los Angeles Times: Sempra solar energy project makes advances in costs.

    This is great as long as the math is real. The company has made quite a few changes from conventional solar, including using cadmium telluride as the semiconductor instead of the more expensive polycrystalline silicon and fashioning them into thinner films.

    I am not a big fan of unverified claims, especially when so much money is likely to be involved. But the exact number is not important. This installation appears to get close to or greater than grid parity without the externalities of fossil fuel power generation (carbon costs, mercury mitigation, etc.) being accounted for on the “conventional” side.

    The future appears to be sunny!

    One small, niggling issue, can we stop calling coal “conventional”? Coal comes from the remains of prehistoric plants that made all their biomass by using the sun as a fuel source, got buried way underground, and, after millions of years at high pressure and no oxygen, formed a carbon rich material that if burned, releases a small fraction of the energy that the sun put in it! As such, using the sun directly as a power source is about as conventional as it gets, everything else is 2nd order, derivative and fairly inefficient.

    Bhutan to pay for others climate sins

    Byoliveridley

    Bhutan is a small country nestled in the Himalayas, breathtakingly beautiful and “quaint”. Unfortunately, it’s about to be hit by a truck!

    Reuters AlertNet – FEATURE-Bhutan to pay for others climate sins

    The retreat of Bhutan’s glaciers presents an even more formidable and fundamental challenge to a nation of around 600,000 people, nearly 80 percent of whom live by farming.

    Bhutan’s rivers sustain not only the country’s farmers, but also the country’s main industry and export earner — hydro-electric power, mostly sold to neighbouring India.

    For a few years, Bhutan’s farmers and its hydro power plants might have more summer melt water than they can use. One day, though, the glaciers may be gone, and the “white gold” upon which the economy depends may dry up.

    The threat led the government’s National Environment Commission to a stark conclusion.

    “Not only human lives and livelihoods are at risk, but the very backbone of the nation’s economy is at the mercy of climate change hazards,” it wrote in a recent report.

    Scientists admit they have little solid data on how Bhutan’s climate is already changing, but say weather patterns are becoming increasingly unpredictable.

    Well, as I keep saying, Americans and Europeans will be incovenienced by global climate change, Asians and Africans will die. I don’t have an answer, though, which is depressing on this gray and cloudy Friday morning…

    The LA Times and the American Chemistry Council

    Byoliveridley

    Giving the American Chemistry Council a forum to sing paeans to its chemical du jour is kinda like giving Donald Trump an Op-Ed column on the harmlessness of gambling. The ACC is a trade association that gets all its funding from the chemical industry and is the reliable source on producing just about enough fudge to create “reasonable doubt” about chemicals. The ACC is notorious for its various astroturf websites including the Phthalate information center, the Plastic Resource, dioxin facts (seeing a pattern here?), and many other websites that propagate biased industry funded research, outright misinformation, and unrestrained cheerleading. They also spend vast amounts of money lobbying congress. Bora, and other Open Access advocates, note the similarities in the arguments used in the above websites to some recent attacks on Open Access, the imprint of Nicholas-Dezenhall is all over the ACC’s strategies!
