Here Comes the Sun

Looks like we may have a paradigm shift underway. This might be the greatest discovery since making fire.

Google: MIT professor Daniel Nocera and light up! The links are starting to multiply.

August 4, 2008 (Computerworld)  Researchers at MIT say they have made an energy storage breakthrough that could transform solar power from an alternative energy source to a mainstream source. The university is calling the solar project a major advancement in energy research.

Sunlight has the greatest potential of any power source to solve the world’s energy problems, Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and a researcher on the project, said in a statement. In one hour, enough sunlight strikes the Earth to provide the entire planet’s energy needs for one year.

“This is a major discovery with enormous implications for the future prosperity of humankind,” Barber said in a statement. “The importance of their discovery cannot be overstated since it opens up the door for developing new technologies for energy production, thus reducing our dependence for fossil fuels and addressing the global climate change problem.”

Taking a page from photosynthesis in plant life, Nocera and Matthew Kanan, a postdoctoral fellow in Nocera’s lab, came up with a process (see video) to use the energy from the sun to split water into hydrogen and oxygen gases, according to a report from MIT. Later, when it’s needed, the gases can be combined inside a fuel cell. That reconnection creates carbon-free electricity that can be used to power an office building, a home or even an electric car – whether the sun is shining or not.

Nocera noted that the process uses natural materials, is inexpensive to conduct and is easy to set up. “That’s why I know this is going to work. It’s so easy to implement,” he said.

“This is the nirvana of what we’ve been talking about for years,” said Nocera. “Solar power has always been a limited, far-off solution. Now, we can seriously think about solar power as unlimited and soon.”

It gets way better, too…

Scotland Fisherman and Conservationists Working together

“It was the islanders who first raised concerns about the decline in fish and other marine life in the bay. Arran was once renowned for its fishing, with hundreds of sea anglers flocking to the island for its annual fish festival. That was decades ago when cod, haddock, hake, dab, plaice and turbot were plentiful in the waters of the Firth of Clyde.

Today the Clyde fishing fleet is a fraction of its original size, and the white fish have gone, leaving only prawns, langoustines and a dwindling stock of scallops. Islanders said the bed of the bay had been left barren after being dragged clean by dredgers – a claim refuted by the fishermen.”

This concern led to a unique collaboration between all stakeholders, eventually resulting in the proposals for significant no-take zones to allow fish stocks to recover. Such zones have been set up before in the UK – a pilot project in 2003 around Lundy Island reported significant recovery in marine life after just 18 months. This is, however, the first time such an effort has been brought about through grassroots collaboration, rather than top-down planning. The result is a significant area of marine habitat that will be left undisturbed by fishing, with an even larger area set aside for strict management:

Green up your cell phone!!

Nokia has unveiled ReMade, a revolutionary mobile phone made of 100% recycled materials.

The idea behind the “remade”? concept was to see if it was possible to create a device made from nothing new. It has been designed using recycled materials that avoid the need for natural resources, reduce landfill, and allow for more energy efficient production.

UN Sec Gen encourages global green economy

In a remarkable step into the worlds of high finance and climate politics, United Nations Secretary-General Ban Ki-moon was in Chicago last week to encourage U.S. business leaders to help reshape the world’s economic future by investing in low-carbon markets.

In a February 7 speech to the Economic Club of Chicago, Secretary-General Ban asked his audience to enter an “age of green economics,”? with the United Nations as a partner.

70,000 Stirling solar generators to be placed in Southwest

On a perfect New Mexico winter day – with the sky almost 10 percent brighter than usual – Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. The old 1984 record of 29.4 percent was toppled Jan. 31 on SES’s “Serial #3” solar dish Stirling system at Sandia’s National Solar Thermal Test Facility.

Osborn says that SES is working to commercialize the record-performing system and has signed power purchase agreements with two major Southern California utilities (Southern California Edison and San Diego Gas & Electric) for up to 1,750 megawatts (MW) of power, representing the world’s two largest solar power contracts. Collectively, these contracts require up to 70,000 solar dish engine units.

India teaching the young about conservation

What’s the most effective way to teach people the value of water and other scarce resources in a world where they are becoming more and more precious? The solution: start young – or at least that’s what progressive, ecologically-minded institutions such as the Vagdevi Vilas at Munne Kolalu, near Bangalore, India, are trying to do. Other institutions such as the Barefoot College in Tilonia, Rajasthan, are also aiming to show the way toward a revolution in the way ecology and sustainability issues are addressed in education and local communities.

Begun three years ago, the school now has 2,300 students on an eight-acre property that performs as a laboratory for putting the school’s ecological education into action

Geek oil?

Yep, some boffins believe they can make what they call a bio-crude oil, using their secret Furafuel technology. Dr Steven Loffler of Forest Biosciences with Australia’s government science research body, CSIRO and his white coated mates at Monash University announced they can, via a chemical process, produce a highly stable oil. This can be readily refined to an equivalent of either petrol or diesel from waste paper, timber and crop wastes.

In fact pretty much anything that is endowed with plenty of lignocellulose. They reckon even forest thinnings, straw and household green garden waste will do the trick. An added benefit of their process is that the bio-crude oil is also PH neutral, so it can be held in storage for a while, before further processing.

You know it is bad when former oil execs are out there condemning gas guzzlers

The former chairman of Anglo-Dutch oil giant Shell has called on the European Union to ban gas-guzzling cars, saying they are unnecessary, the BBC reported Monday. “Nobody needs a car that does 10-15 mpg (miles per gallon, 19-28 litres per 100 kilometres),” Mark Moody-Stuart was quoted as saying.

“We need very tough regulation saying that you can’t drive or build something less than a certain standard. You would be allowed to drive an Aston Martin — but only if it did 50-60 mpg.”

GO MEXICO!!!

In honor of World Wetlands Day, Mexico added 45 wetlands to an international registry that promotes conservation and sustainable development, the Ramsar Convention on Wetlands. Ramsar, which now covers more than 1,699 wetlands totaling 375 million acres, was signed in Ramsar, Iran, in 1971 to coordinate international efforts to conserve wetlands.

Banks applying environmental standards to business loans.

Top U.S. investment banks are set to impose environmental standards that will make it harder for companies to acquire financing for coal-fired power plants, in preparation for government caps on greenhouse-gas emissions, The Wall Street Journal reported on Monday.

The report said Citigroup Inc, JP Morgan Chase & Co, and Morgan Stanley, expect the U.S. government to cap power-plant emissions in the next few years, and will thus require utilities seeking financing for plants to prove that those facilities will be viable under new regulations.

Chemists unveil new process for capturing and storing gas; potential spin-offs include improvements to greenhouse gas  management and fuel cell development

A new process for catching gas from the environment and holding it indefinitely in molecular-sized containers has been developed by a team of University of Calgary researchers, who say it represents a novel method of gas storage that could yield benefits for capturing, storing and transporting gases more safely and efficiently.

And finally for now because this is just cool…Have a condo, you could have a fish farm. No really….

Big fish are moving into the big city. Recent headlines about contaminants found in the sushi of New York restaurants gives us all the more reason to love Yonathan Zohar’s city fish farms. Perfect for the basements of large condos or parked near a big city market, Zohar’s commercial fish farms solve a number of problems.

“It is clear that the consumption of seafood and fish is on the rise, because of the great health benefits… but now we are over-harvesting,” warns Zohar, director of the Center of Marine Biotechnology at the University of Maryland. “We need to change that practice and become more efficient in a way that is compatible to the earth.”

Using advanced concepts of microbiology, Zohar has entrained special microbes to live in symbiosis with the fish in order to digest their waste, 21c reports. Aerated by plastic plugs that house the microbes, the fish pools are bio-secure and contaminant free.

Waiting for Home Solar Panels?

Wouldn’t it be great if rooftops all over the country generated electricty from the sun?  It is rumored that Nicola Tesla, father of alternating current was given funding by American tycoon J.P. Morgan.  Tesla’s dream was free energy for all but J.P. said, “That’s all well and good Mr. Tesla, but where do I put my meter”.

I present a trade magazine article illustrating a barrier to implementing such an idea.  Read on while I translate the businessease doublespeak and compare it to other electronic business successes stories.

Water Shortage Shuts Down TVA Nuke Plant

I posted this yesterday at Daily Kos – under a different title “Nuclear is Not the Answer”.  The pro- nuke shills immediately descended upon the diary and I’m only now coming up for breath.  Maybe some folks here will read it for what it’s about – our current (and future) shortage of cool water is a major problem for nuclear plants.

Here’s the diary:

Nuclear power is not the answer to global climate change. Other than the safety issues connected to nuclear waste, which are pretty well-publicized, there is a major problem with thermal load, which is not so well known.

Nuclear plants need cool water for cooling.  Hotter water temperatures in the Tennessee River this summer caused TVA to suspend operations at their Browns Ferry Plant.  Browns Ferry is downstream from 3 other TVA nukes which had already heated up the river to a point to prohibit further heating.

France and Germany have had the same problem – in the 2003 heat wave.  The rivers on which their nuclear plants were built were heating up beyond their environmental agenies’ standards for aquatic life. A choice had to be made between nuclear power and the health of their rivers and aquatic life. 

As folks who read the great diary this weekend on Atlanta’s water shortage must recognize, with climate change and rising temps, the cool water necessary for nuke plants will be a scarcity
