Imagine a world covered with solar cells

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.

    A Dated Carbon Approach

    You can even cut carbon using no technology whatever. Mexico City has reduced its output of carbon dioxide by almost 55,000 tons a year by opening one efficient bus route; the key innovation here was the creation of two bus lanes. The new buses run on diesel — not exactly a technological breakthrough. But because they are rapid and frequent, the buses have brought car use down and reduced emissions. So what matters is not just the technologies we have but the incentives to deploy them. The average Western European uses half as much energy as the average American, and that’s not because there’s more technology in Europe. Rather, Europeans have embraced anti-carbon policies ranging from gas taxes to emissions caps, from an absence of extravagant mortgage subsidies that encourage super-size homes to congestion charges for drivers in London and Stockholm.

    Sing it, Cap’n Obvious, actually, it is not obvious to a lot of people. Politicians love “research” because they can turn around and say that they are doing something about a problem when all they are doing is postponing the discussion by calling for “new technology” to fix the problem. Scientists like this as well because this means money in their pocket. Research groups, be they in universities or in government institutes, perpetuate themselves by getting more funding to do more research, which leads to getting more funding to do more research while keeping an army of post docs, grad students, research assistants and professors gainfully employed. It’s kinda like reproduction, only less fun! It is a good system and a lot of good work gets done, but for a lot of questions, the answers are already there.

    Policy level decisions require that clear cut choices be made, while they are NOT zero sum games, there are winners and losers in most of the decisions, and this current incarnation of politicians do not seem to want to make these kinds of decisions unless the winners are big companies (energy, pharma, healthcare, etc), rich people (tax cuts, etc.) or war.

    Sea Turtle News o' the day – Global warming edition

    ScienceDaily: Scientists Warn Of Climate Change Risk To Marine Turtles

    North American marine turtles are at risk if global warming occurs at predicted levels, according to scientists from the University of Exeter. An increase in temperatures of just one degree Celsius could completely eliminate the birth of male turtles from some beaches. A rise of three degrees Celsius would lead to extreme levels of infant mortality and declines in nesting beaches across the USA.

    Here’s the paper.

    Like a lot of other reptiles, the sex of the hatchling is dependent on nest temperature. Warmer temperatures make female turtles (my mnemonic was hot females!), and even warmer temperatures just kill the eggs. But, I wonder if the turtles would adapt by nesting a little earlier. I don’t think it is yet clear when turtles decide to nest. If it is based on sea temperature, then they would eventually figure it out. This paper from 2004 appears to conclude that loggerheads in Florida do nest earlier than before, so there is hope.

    John F. Weishampel, Dean A. Bagley, Llewellyn M. Ehrhart (2004) Earlier nesting by loggerhead sea turtles following sea surface warming Global Change Biology 10 (8), 1424–1427

    The onset of spring, noted by the timing of wildlife migratory and breeding behaviors, has been occurring earlier over the past few decades. Here, we examine 15 years of loggerhead sea turtle, Caretta caretta, nesting patterns along a 40.5 km beach on Florida’s Atlantic coast. This small section of beach is considered to be the most important nesting area for this threatened species in the western hemisphere. From 1989 to 2003, the annual number of nests fluctuated between 13 000 and 25 000 without a conspicuous trend; however, based on a regression analysis, the median nesting date became earlier by roughly 10 days. The Julian day of median nesting was significantly correlated with near-shore, May sea surface temperatures that warmed an average of 0.8°C over this period. This marine example from warm temperate/subtropical waters represents another response of nature to recent climate trends.

    So the truth lies somewhere between easy adaptation and giant swarms of frustrated female turtles!

  • Cost benefit Analysis of Air Pollution Regulation

    Well, looks like old fashioned regulation actually stands up to Cost Benefit analysis. The problem is that the costs are to Industry, a well organized bunch of folks with lobbies, scientists, and such, and the benefits are primarily to the general population, well, they get a choice every few years!

    Chemical & Engineering News: Latest News – Budget Office Reports On Regulations:

    Budget Office Reports On Regulations EPA air pollution rule helps boost overall societal benefits of federal actions Cheryl Hogue A 2005 air pollution rule is a major reason why benefits from federal regulations continue to outpace costs, says a draft White House Office of Management & Budget report released on April 13. Federal regulations issued between 1996 and 2005 generate total annual benefits estimated to be between $94 billion and $449 billion, the OMB report says. Costs of those rules, which range from health and education standards to transportation and labor regulations, are estimated to be between $37 billion and $44 billion yearly, the draft report says. The document is the 2006 installment of an analysis that OMB by law must prepare each year for Congress. The ratio of benefits to costs is higher for the 1996–2005 decade than it was between 1995 and 2004 primarily because of a single rule reducing air pollution from power plants, the draft report says. That EPA regulation requires 28 eastern states and the District of Columbia to control sulfur dioxide and nitrogen oxide, two key pollutants released by coal-fired power plants. According to the draft report, that rule will generate from $50 billion to $60 billion a year worth of health benefits by reducing public exposure to fine particulate matter. This rule will cost about $1.8 billion annually to implement. Most of the costs and benefits of federal regulation are due to EPA rules, the draft report adds. During the 1996–2005 decade, the annual benefits of the agency’s rules are calculated to be between $59 billion and $394 billion, while estimated costs ranged from $24 billion to $26 billion.

  • Magic Box under your car makes all your problems go away

    But, will it make tea? File it under the “too good to be true” department. I’ll believe it when it happens.

    From Wales, a box to make biofuel from car fumes: Scientific American

    The world’s richest corporations and finest minds spend billions trying to solve the problem of carbon emissions, but three fishing buddies in North Wales believe they have cracked it.

    They have developed a box which they say can be fixed underneath a car in place of the exhaust to trap the greenhouse gases blamed for global warming — including carbon dioxide and nitrous oxide — and emit mostly water vapor.

    The captured gases can be processed to create a biofuel using genetically modified algae.

    So, what they’re saying is that they have designed a device that can safely sequester most of the toxic components of automobile exhaust for a little while. Then, you take this “magic box” down to your local refinery where this sequestered gas is mixed with some algae. The algae then uses this CO2 as fuel to make biodiesel.

    Very cool in concept. Kinda hard to critcize without the details, No?

  • EPA chief: Bush climate policy working

    If by working, you mean increasing CO2 is good for the world, a warm place is a better place, right!

    EPA chief: Bush climate policy working – Yahoo News

    The EPA said its annual greenhouse gas assessment showed that 7.26 billion metric tons of carbon dioxide and other heat-trapping gases were released by U.S. sources in 2005, an increase of 0.8 percent from the previous year.

    “The Bush administration’s unparalleled financial, international and domestic commitment to reducing greenhouse gas emissions is delivering real results,” Johnson proclaimed in a statement.

    This statement makes perfect sense and is the complete truth if you assume that increasing GHG emissions demonstrates “unparalleled” commitment to “reducing” greenhouse gas emissions? Unparalleled all right! Nobody’s better at emitting CO2 than the U.S of A! Wohoo!!

  • EU outpaces United States on Chemical safety

    Dog bites man news o’ the day!

    ScienceDaily: European Union Outpaces United States On Chemical Safety

    In the 1970s and ’80s, the United States effectively set many global product standards for consumer and environmental protection. Today, Europe is playing this role, while U.S. government and industry oppose the resulting standards in Europe and in international arenas.

    The size of the European market (more than 485 million citizens) will push manufacturers in the United States and Asia to meet European standards and will increase the availability of “green” products globally, contend the authors. Additionally, the new toxic risk information generated by REACH may allow environmental advocates in the United States and elsewhere to focus their efforts with specific, supportable data.

    Amen to that, you can either lead, or be forced to follow. EU policies are far from perfect, and as vulnerable to politics, hypocrisy and competing interests as any other “country’s” policies. But, you can never fault them for lack of effort, and they do not seem to have suffered from any consequences to using the precautionary principle.

    When an activity raises threats of harm to the environment or human health, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically.

    Not so hard to grasp. But here’s the precautionary principle the US of A uses. I propose calling it the plutocracy-protectionary principleTM.

    When a proposed regulation raises threats of harm to the short term shareholder returns of an industry, precautionary measures to oppose this regulation must be taken even if cause and effect relationships are clearly established, or if scientific research has shown the opposite effect to the industry claim being made.
