Pothole power for cars

Via the TNR E&E blog comes this story of capturing some of the energy wasted when a vehicle moves over bumps and potholes on the road. Indian drivers are waiting with bated breath for this prototype to become a reality! The takeaway messages are that most of the mechanical devices we use today have many points where waste energy can be captured and put to use.

A team of MIT undergraduate students has invented a shock absorber that harnesses energy from small bumps in the road, generating electricity while it smoothes the ride more effectively than conventional shocks. The students hope to initially find customers among companies that operate large fleets of heavy vehicles. They have already drawn interest from the U.S. military and several truck manufacturers.

  • Sethusamudram – A typical Indian development project

    The Sethusamudram (bridge sea – for the transliterators) project has the classic development plot lines that I’ve seen play out many times in India. Here’s a rationale from the official site…

    Currently the ships coming from the west coast of India and other western countries with destination in the east coast of India and also in Bangladesh, China etc have to navigate around Srilankan coast. The existing water way is shallow and not sufficient for the movement of ships. This is due to the presence of a shallow region known as Adam’s bridge, located southeast of Rameswaram near Pamban, which connects the Talimannar Coast of Srilanka

    What? They are going to destroy the bridge that rama and the vanaras built? Look at that picture, (thanks Manitham), can’t you see all the “Vanaras” (this has always struck me as racist – folks showing up from the North and calling the darker skinned Southerners Monkeys! But that is a different rant) running across the very clearly delineated land bridge – It’s fascinating, almost makes me believe that the Ramayana happened as narrated!

    Manitham has a good rundown of the project from an activist standpoint.

    A few points

    • The secrecy and lack of transparency are classic government techniques to control the flow of information and discourse. Every government does it, and the Indian government is no exception.
    • Environmental Impact Assessments are bought and paid for by the funding agency, and are hence essentially unreliable and untrustworthy. I had first hand experience of this when I was a student at IIT Bombay 10 years back.
    • There is a lot of politics involved, the port of Tuthukudi (Tuticorin as the damn Brits say) in Tamil Nadu is a clear winner and Colombo in SriLanka stands to lose revenue. There is also a great deal of Tamil Pride involved
    • Read this excellent article from the climate.lk clearinghouse of articles : There is a security dimension here for India that may have been the actual motivation.
    • The area, due to its sheltering and shallow waters, has a lot of marine life. From a 2004 Deccan Herald Article

    The series of meetings called by the Tuticorin Port Trust chairman in the coastal districts have turned out to be stormy with representatives of political parties shouting down objections from fishermen, who fear the loss of livelihood, and environmentalists who say the project threatens to destroy the Gulf of Mannar Marine Reserve. This reserve is one of India’s most biologically diverse coastal regions.
    Over 3,600 species of plants and animals are found here. It is the first marine biosphere reserve in the South and South-East Asia and is believed to have the highest concentration of seagrass species along India’s coast. It is also among the largest remaining feeding grounds for the globally endangered species dugong. Five different species of endangered marine turtles, innumerable fish, molluscs and crustaceans are also found here. The Bombay Natural History Society (BNHS), the largest NGO working in the field of bio-diversity and environmental conservation, has said the rapid Environmental Impact Assessment (EIA) report prepared by the National Environmental Engineering Research Institute (NEERI) is insufficient and a detailed study should be conducted in all seasons for at least a year.

    • The EIA actually says that since the seaway is 20 km away from the reserve, there will be no effect on the reserve, um, that seems highly unlikely to me…
    • The other major dimension is the usual utter lack of care for the people displaced. previous instances like the Sardar Sarovar project indicate that there will be no fair compensation for the displaced people, or for lost livelihood, which I guess is perfectly fine because it serves the greater good of the country?

    Most of these big projects have resulted in overstated gains, understated losses, and huge wastes of taxpayer money. I don’t trust this to be any different. The facts look fudged, the project seems unnecessary (where’s my tamil pride?) and the effect on the wildlife and the crazy complex current system around Sri Lanka may change significantly leading to unforseen micro climate effects.

    Two thumbs down…

  • Lobbyist, Fed Lawyer Share Vacation Home

    Plutocrat, meet protectionist!
    Lobbyist, Fed Lawyer Share Vacation Home | World Latest | Guardian Unlimited

    Nine months before agreeing to let ConocoPhillips delay a half-billion-dollar pollution cleanup, the government’s top environmental prosecutor bought a $1 million vacation home with the company’s top lobbyist.

    Also in on the Kiawah Island, S.C., house deal was former Deputy Interior Secretary J. Steven Griles, the highest-ranking Bush administration official targeted for criminal prosecution in the Jack Abramoff corruption probe.

    Just before resigning last month, Assistant Attorney General Sue Ellen Wooldridge signed two proposed consent decrees with ConocoPhillips: one giving the company as much as two to three more years to install $525 million in pollution controls at nine refineries and the other dealing with a Superfund toxic waste cleanup.

    I am slowly coming to the realization that the words democracy and accountability have no meaning whatsoever in the good ol’ US of A. Remember this the next time you hear a lecture from your usual American diplomat/administration lackey about democracy and corruption in other countries.

  • Study Says U.S. Companies Lag on Global Warming – New York Times

    Study Says U.S. Companies Lag on Global Warming – New York Times

    European and Asian companies are paying more attention to global warming than their American counterparts. And chemical companies are more focused on the issue than oil companies.

    Those are two conclusions from “Corporate Governance and Climate Change: Making the Connection,” a report that Ceres, a coalition of investors and environmentalists, expects will influence investment decisions.

    The report, released yesterday, scored 100 global corporations — 74 of them based in the United States — on their strategies for curbing greenhouse gases. It covered 10 industries — oil and gas, chemicals, metals, electric power, automotive, forest products, coal, food, industrial equipment and airlines — whose activities were most likely to emit greenhouse gases. It evaluated companies on their board oversight, management performance, public disclosure, greenhouse gas emissions, accounting and strategic planning.

    The report gave the chemical industry the highest overall marks, with a score of 51.9 out of a possible 100; DuPont, with 85 points, was the highest-ranking American company in any of the industries. Airlines, in contrast, ranked lowest, with a score of 16.6; UAL, the parent of United Airlines, received just 3 points.

    Well, clearly government policy and media attitudes have more to do with market behavior and regulation than the “free market fundamentalists” would care to accept.

  • Canada's Greatest Scientist

    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.

    Grad student measures hazardous levels of air pollution at cigar show

    Sure makes my graduate work in air quality seem a little tame!

    The man behind the subterfuge (Researcher 2, male) was Ryan David Kennedy, 34, a scrappy Canadian graduate student with crooked glasses who is studying the impact of tobacco on air quality.He crossed the border at Buffalo on Monday morning and on Tuesday crashed the giant cigar party and trade show sponsored by the publisher of Cigar Aficionado magazine at the Marriott Marquis in Times Square.

    At a Cigar Show, an Air-Quality Scientist Under Deep, Smoky Cover – New York Times

    Well, what did he find? Particulate matter readings four times higher than “hazardous”. Sometimes I think of strapping on a sampler and going to the local bar just out of curiosity. I can leave the bar if it gets smoky, the bartenders and wait staff can’t. I don’t see why this is not a clear case of hazardous working conditions leading to an immediate indoor smoking ban.  but what do I know, I’m just a scientist!

    Happy Thanksgiving.

  • Rising Temperatures Affect Indian Crop Yields

    feb-temp.jpgThis story in the Indian Express talks about unusually warm February weather affecting wheat yields in Punjab and Haryana (India’s breadbasket, BTW). This will become more and more common as average temperatures rise from Global Warming. From Lester Brown’s most informative book Plan B 2.0:

    Two scientists in India, K.S. Kavi Kumar and Jyoti Parikh, assessed the effect of higher temperatures on wheat and rice yields. Basing their model on data from 10 sites, they concluded that in north India a 1-degree Celsius rise in mean temperature did not meaningfully reduce wheat yields, but a 2-degree rise lowered yields at almost all the sites. When they looked at temperature change alone, a 2-degree Celsius rise led to a decline in irrigated wheat yields ranging from 37 percent to 58 percent. When they combined the negative effects of higher temperature with the positive effects of CO2 fertilization, the decline in yields among the various sites ranged from 8 percent to 38 percent. For a country projected to add 500 million people by mid-century, this is a troubling prospect

    We might as well accept that this is going to happen and plan
    accordingly. I guess changing the variety would help, so would shifting the growing season a little (I am no crop scientist, so I need to read about this).
