Technology to Make Concrete Structures Last 16000 Years

Ecogeek has this piece (via Greentech Media) about the smart guys at MIT devising the technology to make concrete last millenia instead of the decades that we are used to: http://ecogeek.org/component/content/article/2814 As the piece says, the technology alterts how concrete degenerates with strain, making it last several magnitudes longer than we now expect it to. A very good idea, I think, especially in public structures which are not midified or altered as much as private homes are. Let's see if this picks up in South Asia - that part of the world has the most infrastructure projects going after China.

Just a reminder that this blog subscribes to both Ecogeek as well as Greentech, and both are superb blogs to visit for the latest in various technologies that would ensure that we show fossil fuels the fist.

Why On Earth is This Not Being Implemented in Chennai?

For the past thirty years at least, as I can recall, the British have sent technology and money to help clean up the Cooum River / Buckingham canal in Chennai, but nothing has happened. Where has the money gone? Those in the Tamilnadu State government know, if someone does. And the two outlets, once navigable canals in which boats went all the way to Chingleput, become filthier by the day with more and more sewage pumped into them. The Adyar River, on whose banks much of the Chennai elite lives along Boat Club Road and Archbishop Mathias Avenue, is yet another example of a water body that was once clean turned into a filthy cess carrying canal by the State government.

Dr Mayraj Fahim, who has been a strong supporter of this blog, has sent me a very interesting link which has implications for Chennai: http://www.dailymail.co.uk/news/article-1193169/Human-waste-heat-thousands-homes-4m-plan-recycle-gas.html British utilities already send sewage derived gas to generate power, and they now plan to offer the same gas for use in domestic kitchens etc. How difficult would it be for the Government of India and the Tamilnadu State government to revive the old British initiative and get the relevant technology from the UK to implement large-scale projects along these outlets? The raw material is there, and, it is not going to diminish in quantity as long as Chennai-vasis eat and then clear their stomachs out. There is an old initiative where the British have offered support - perhaps, the state could look at creating a utility under the common administration of the Water and Electricity Boards to use gas to generate electricity for the city? Or, alternately, as there are many gas powered cars running in the city, use this to supplement gas supplies for fueling vehicles and save foreign exchange?

Is anyone listening? Our Prime Minister who is supposed to turn the country into a new superopwer, perhaps? Or the Chief Minister whose wisdom is always hailed by his followers? Anyone? United Utilities, the British business involved in this project, has a nice website: http://www.unitedutilities.com/ Over to India . . .

Congratulations! India's First Solar Powered Floating Store Launches in Kerala

The state of Kerala in South India is a beautiful place. It has backwaters (canals for non-Indians) and is green throughout. The residents of the state have a passion for watercraft because of the many canals and the long coast. I have fond memories of the place as I have relatives in Kozhikode and friends in Fort Cochin, Palghat, Ayalur, Nemmara, Ochera etc. And if you can excuse the constant strikes that plague the state thanks to its Communists, it can actually be a nice place to spend some time in.

But let's leave the negative stuff out. I posted a link some time ago to a solar powered ferry-boat built in the state on this blog. Now, the idea has been taken further: A solar powered store is due to sell various goods to communities living along the backwaters: http://www.ecofriend.org/entry/eco-tech-india-gets-its-first-ever-solar-powered-floating-supermarket/ It is a bit of a stretch to call this a "supermarket," but I do think that the promoters of the floating Thriveni Superstore, the Kerala Government owned Kerala State Cooperative Consumers Federation Ltd, have much to pat themselves on the back for. Everyone involved in this project deserves kudos.

Electric Airplane Sets Speed Record

Yes, there are road cars that can go faster than this airplane and for longer. But this is an achievement that is absolutely on the right path ahead: http://www.autobloggreen.com/2009/06/15/new-electric-airplane-sets-world-record-for-speed-w-video/ Autoblog Green Must be thanked for giving this achievement publicity.

The world's car manufacturers are making decent strides (albeit sometimes reluctantly) as far as fuel efficiency is concerned. But aircraft and watercraft have been a different cup of tea so far. All work in these areas has been on a small scale and laws pishing these companies to do something significant have been few. That said, airlines like Emirates, Japan Air Lines and Air India have done some work in reducing the amount of fuel burned in take offs and landing by tinkering with time schedules and similar. However, it is only technological breakthroughs in electric aircraft power that will help reduce the use of fossil fuels in the air significantly. That said, algae based fuels have been successfully tested by the Japanese as well as by the US Air Force, though, there again, carbon is emitted into the air. My hat's off to the Sky Spark team.

China Throws Down a Renewable Energy Challenge to the World

While it is currently one of the world's most heavily polluted countries and it needs to import over 90% of its oil, China has decided to act in a manner that needs to be applauded: http://seekingalpha.com/article/142617-china-becomes-global-green-leader-with-massive-solar-projects?source=yahoo I am grateful to Dr Mayraj Fahim for this link showing where South Asian countries, which enjoy the same climatic conditions and suffer from similarly high pollution, are lagging seriously behind. So, for that matter, is the USA where the only action forward seems to be Barack Obama's pious talk along with the constant and stale applause of his drum-beaters in the media and in the blogosphere. While well intentioned US plans like the Pickens proposals fall by the wayside, the Chinese seem to power ahead with their desire to insulate their country from the vagaries and whims of the oil producing nations and of oil traders and their manipulations.

Yes, China has coal - so does India, but the Chinese consider their coal reserves a finite asset. India has no hesitation in preserving some of its own coal reserves while it encourages massive environmental degradation in Indonesia, Australia, South Africa and elsewhere by mining for coal there and pollutes the air and the seas by shipping it back to India. And, though India has recently articulated a massive proposal to work on solar power, it is going to be difficult for it to do much as it is way behind China on the neccessary manufacturing infrastructure to produce solar and other RE equipment.

However, this is a situation that could be a wake-up call if you ask me. There is no reason why South Asian countries - and India, Pakistan, Bangladesh, Sri Lanka etc all have excellent engineers and facilities with which to manufacture / develop renewable energy products. This could be the spark with which to ignite a powerful flame (well, yes, this is an inept simile) of Renewable Energy in South Asia. Our antions would be wealthier because of money saved, our air, water and soil cleaner, and our workers treated more humanely as they no longer have to work in near-slavish conditions in Arab countries.

Let's hope this competition is joined, and, at the soonest.

Why Public Transport May Not Really be Green

I am grateful to Dr Mayraj Fahim for this link: http://news.yahoo.com/s/afp/20090608/sc_afp/climatewarmingtransportcarbonlifestyle While some dedicated environmental groups have, in the past, audited the environmental impact of the manufacturing process of various goods and means of transport, the practice has not always been given the publicity that it deserves. Now, with scientists looking at public transport, some common beliefs about supposedly "green" transportation are being challenged.

Specifically, the issue about trains is something that I have suspected for some time and I did get into a brief discussion on this at Low Tech Magazine: http://www.lowtechmagazine.com/2008/12/train-travel.html#comments There is no question that trains are at their most efficient at hauling heavy freight or large numbers of people. try and make them luxury vehicles on wheels like they are in the USA, and their efficiency drops. Hopefully, there will be a comparison of the efficiency of local trains in cities like New York with decent public transportation with local commutes as well as with failing, state-owned businesses like Amtrak with cars in long distance travel so that a specific environmental impact in each case is better understood. As far as showing fossil fuels the fist is concerned, I do think that the more efficient the means of transportation, the lower its carbon footprint would be. Let's hope that we get more expert views on this in the near future.

The New York Times Looks at India's New Solar Plans

The new solar plans that India articulated while the election campaign was on (and which I was cautiously optimistic about) are now being looked at by the New York Times: http://greeninc.blogs.nytimes.com/2009/06/05/could-india-become-a-solar-leader/ The fact is that India does have the potential to become a solar leader. The country is bathed in sunshine most of the year. There is no question about the fact that sunlight is a resource that could be tapped into, and which has not been seriously considered by India so far. There is also no question that other than talk, India has done little (with the exception of small initiatives by states like Karnataka and Haryana and municipalities around Mumbai for example to encourage solar powered water heaters) about harnessing what the country has in abundance, so far.

The NYT report, though, does make sense in talking about the support that India needs from foreign nations that have done vastly more work in this area than India has done. I do think that this is a good idea - India has excellent engineers and if Indians could do well in writing computer software, for example, they could also do well in working on solar power. A good beginning would be a major plus. And, international help, especially from the USA, is available. The US Exim Bank has funding worth $ 5.5 billion available for Renewable Energy co-operation between the USA and India for 2009 alone. As far as I know, hardly any of this money has been touched. From the focus of the current US government, the amount available in 2010 would, most probably, be higher. And there are superb US designed and made products that could be replicated in India under license from the US patent holders to help achieve the Indian goals.

I shall admit that I am not a supporter of any Indian political party or government - I like being skeptical of politicians like many Indians are. That said, there are two governments - one in the USA and the other in India - that have been talking about renewable energy with increasing fervor. The USA has put money (through the Exim Bank) where its mouth is. Now that India has come up with a plan ahead especially with a focus on solar power, there is the potential for a very positive way forward on this in the future. What will decide whether the two governments are serious about this thrust will be how the Indian plans are implemented. Those who read this blog know, certainly, where my hopes on this lie.
