Imagine a world covered with solar cells

Byoliveridley

it could happen soon, imagine your car parked in the sun with a plastic solar coating on the roof. Imagine every building surface generating clean electrical energy. Well, it could happen very soon (if hyperbolic sciencedaily press releases are to be believed, at any rate!).

ScienceDaily: New Plastic Solar Cell Breaks Efficiency Record

In order to be considered a viable technology for commercial use, solar cells must be able to convert about 8 percent of the energy in sunlight to electricity. Wake Forest researchers hope to reach 10 percent in the next year, said Carroll, who is also associate professor of physics at Wake Forest.

Because they are flexible and easy to work with, plastic solar cells could be used as a replacement for roof tiling or home siding products or incorporated into traditional building facades. These energy harvesting devices could also be placed on automobiles. Since plastic solar cells are much lighter than the silicon solar panels structures do not have to be reinforced to support additional weight.

Screw ethanol, put all your energy into developing solar and wind energy, battery technology and electric vehicles. See how much better an idea that is compared to corn ethanol.

  • GE – weakening air pollution standards

    Byoliveridley

    GE – we bring good things to life (and kill them with Diesel exhaust).

    Clean Air Watch – Blog for Clean Air

    General Electric Co., which is running a marketing campaign promoting itself as environmentally friendly, has pushed to weaken smog controls for railroad locomotives in rules about to be proposed by the Environmental Protection Agency.

    The rules, which could take effect between 2011 and 2017, are designed to cut smog and soot levels and would replace standards adopted in 1997. Since the rules would apply to new locomotives and could require changes on older ones, they would have a big effect on GE, which dominates the nearly $2 billion-a-year North American locomotive market. While the nation’s other locomotive maker and diesel-engine makers say they are prepared to meet the proposed new standard, GE argues it is “unlikely to be achieved” and has proposed a weaker one.

    I have nothing to say, just another example of the plutocracy-protectionary principle, nothing new, same old Modus Operandi.

  • EU's REACH Program's cornucopia of toxicology data

    Byoliveridley

    The REACH program from the European Union is an incredibly far reaching (no pun intended, of course!) effort to catalog the effects of chemical compounds on human health. I came across this interesting article at Environmental Science and Technology.

    ES&T Online News: Will the EU’s REACH serve researchers’ needs?

    Europe’s new chemicals law, REACH (Registration, Evaluation, and Authorisation of Chemicals), will put about $13 billion worth of data on 30,000 substances onto a searchable database made available at no cost on the Internet. It sounds like a dream come true for researchers wanting to design new compounds free of the structures that cause human health hazards. But lack of funding for basic research and concerns about the competence of toxicity tests have dampened expectations among some scientists.

    Well, D’uh, any program that big is bound to have some problems. But the shifting of burden of proof away from the regulators to industry is a big deal and will lead to a lot of self regulation. Companies will have to prove that their chemicals are safe.

    John Warner, a synthetic organic chemist at the University of Massachusetts, says REACH will be effective at pushing companies to select safer alternatives that are already on the market. But for the many reagents and solvents that have no safe alternatives, safe molecules must be designed, and REACH is not structured to promote the design work, Warner says.

    Yes, this is an effort to regulate existing and new chemical entities, not an initiative to spur innovation. From the REACH site:

    The REACH Regulation gives greater responsibility to industry
    to manage the risks from chemicals and to provide safety information
    on the substances. Manufacturers and importers will be required
    to gather information on the properties of their substances,
    which will help them manage them safely, and to register the
    information in a central database.

    The innovation is going to be market driven by the fear of this regulation. Maybe we will start calling it OVERREACH!

  • Canada's Greatest Scientist

    Byoliveridley

    Is apparently someone called Rex Murphy who writes political and social columns for Canada’s premier newspaper, who has done what thousands of scientists all over the world could not do: Solve the issue of global warming by pointing out that Toronto is having a very cool July.

    So where’s that global cooling alert? – The Globe and Mail

    Now, however, Toronto in July is cool and I am waiting in vain for the lips of just one forecaster to ask how can this be. Waiting just once to hear the familiar phrase “global warming” in a sentence that even hints that the theory behind it is so much more tentative than we have been urged with such fervour to believe.

    It was so easy, the solution was in front of us all this time, why did no other scientist not use the obvious connecting equation: Weather (in one’s hometown in July) = Climate?? Damn, there goes my Nobel. Sometimes, it is that easy!

    Next week on the Globe and Mail: Isee Flaturtha stands on top of a hill, looks all around, can see nothing but flat land for miles and miles, publishes an opinion piece proving that the Earth is flat and excoriating the so called “Round Earth” scientists.

    I am glad that Canada’s best newspaper is open to such great scientific writing. Clearly, Canada’s future is bright.

  • Whales Protected from Navy for Now

    Byoliveridley

    The Navy is not “exempted from compliance with the National Environmental Policy Act” and a court injunction creating a 12 nautical-mile no-sonar zone off Southern California, U.S. District Judge Florence-Marie Cooper wrote in a 36-page decision.

    “We disagree with the (exemption) judge’s decision,” White House spokesman Tony Fratto said. “We believe the (exemption) orders are legal and appropriate.”Navy spokeswoman Lt. Cmdr. Cindy Moore said the military was studying the decision.

    The president signed a waiver January 15 exempting the Navy and its anti-submarine warfare exercises from a preliminary injunction creating a 12 nautical-mile no-sonar zone off Southern California. The Navy’s attorneys argued in court last week that he was within his legal rights.

    Judge to Navy: Limit sonar training – CNN.com

    There is little doubt that sonar severely disrupts whale communication and can lead to bizarre behavior and decompression sickness. Here’s a video (narrated by Pierce Brosnan, no less!) that sheds some light on this issue.

  • The Harper chill factor

    Byoliveridley

    The crisis over who will be in charge in Ottawa in the new year is making waves at the United Nations climate change conference in Poznan, Poland, with many delegates expressing hope that Prime Minister Stephen Harper will be ousted, a Montreal observer said at the conference.

    “I've had delegates from all over the world coming up to me and asking what is happening in Canada, and frankly, in the vast majority of cases, they are saying they wish the government would fall. The Harper government is not popular here,” said Steven Guilbeault, a representative of Montreal-based Équiterre and one of about 9,000 participants in the 14th annual Conference of the Parties to the United Nations Framework Convention on Climate Change.

    As Canada takes a timeout on installing a more representative government, a quick reminder that Harper’s conservative government is a climate dissembler, denier and liar.

    Coffee Roasting and Popcorn Lung

    Byoliveridley

    Cross-posted from Interrobang

    Who among us coffee drinkers don’t love the smell of freshly roasted coffee? I am sure some of us imagine how much fun it would be to smell freshly roasting coffee more often. I don’t, because smell for me is an instant jolt of pleasure/pain followed by a rather rapid decline into the background.

    Caution, though. New measurements from the US Centres for Disease Control warn of high exposure to some pretty nasty chemicals that can cause your lungs to be destroyed irreversibly, the unfortunately named “popcorn lung” or bronchitis obliterans:

    Investigators with the National Institute of Occupational Safety and Health, a research arm of the CDC, spent several days at Madison-based Just Coffee in July. Investigators tested personal air space and took air samples to measure the concentration of the chemicals diacetyl and 2,3-pentanedione… NIOSH researchers found levels in three breathing-zone samples that exceeded the safety levels recommended by the CDC.

    Coffee Roasting Plants and Exposure

    The test results show a marginal exceedance in this case, but noted that ventilation is a big factor and these tests were done under well ventilated conditions on a warm and dry day when doors were open. So, exposure can be higher in other circumstances.

    Worker exposures are to higher levels, and are more sustained, so they deserve the most attention.

    So, local coffee roasters, it may make sense to confirm that your roasting environments are not exposing your workers to harmful, lung obliterating chemicals. Remember, organic, shade grown, fair pay, artisanal roasting aside, chemical exposures to workers don’t change. And, everything that smells good isn’t good for you.

    One of my frequent points of emphasis (rants, some might say) is on the relative risk vs. media attention to exposures of people to ambient, day to day concentrations of potential harmful chemicals vs. those faced by workers everywhere. The last time diacetyl and bronchitis obliterans were in the news, it was around the use of diacetyl to produce that buttery smell so beloved in microwave bag popcorn (I don’t like it myself, olive oil all the way!). Despite reports of many workers facing severe lung issues, it took the detection of the disease of one person eating multiple bags of microwave popcorn over many years to actually move government regulators into action on diacetyl. People who work in factories, in the fields, and make things are exposed to thousands of times higher concentrations of harmful chemicals for longer periods of time, but their concerns are often de-emphasized.

    This doesn’t mean ambient exposures in the general population are to be ignored, but worker exposures are to higher levels, and more sustained, so they deserve the most attention.

    16-May-2016 Update

    This US Centers for Disease Control page is a good collection of information and further readings. They recommend facility tests to measure diacetyl and its cousin 2,3-pentanedione, and better ventilation, worker safeguards and personal protective equipment as necessary. They also note that at least five workers in large scale coffee processing plants have been diagnosed with bronchitis obliterans.
