Algae Power



another great one from BLDGBlog:

A proposal in Iceland for alternative energy created from algae pond gases. Be sure to check out the full range of drawings and analysis with your own presentations in mind.

Ice Cube


From BLDGBlog:

Last week, New Scientist reported that a neutrino detector called IceCube, once constructed, might just do exactly that.
Because the Earth rotates, we read, distant neutrino sources – such as black holes – will be blocked at certain predictable moments by the Earth's core; piecing together all these temporary blindspots, we can then infer the shape of the core itself.
It's an absence that generates absences elsewhere.

According to The Daily Galaxy, building the IceCube is less an act of construction than a kind of archaeology in reverse; the process will consist of entombing "glass-globed sensors the size of basketballs on 1-mile-long strings, 60 sensors per string, in 80 deep holes beneath the polar surface."

For more on the IceCube and Antarctic science in general give this article in The Economist a quick read – then check out NOVA's round-up of weird detectors.
Then, if you're looking for a good book on Antarctica itself, consider picking up a copy of Terra Antarctica: Looking into the Emptiest Continent by William L. Fox (a book previously mentioned on BLDGBLOG here).

Forum: Science and Innovation for Sustainable Development

The Forum is an excellent resource for information on current research being done by people with specific technical and methodological skills. It is a clearinghouse of published work from international researchers, scientists, engineers, and social scientists working in the fields that related to issues of sustainability ranging from water and sanitation to agriculture to urbanism.

"The Forum on Science and Innovation for Sustainable Development is an attempt to outline the burgeoning field. Rather than looking broadly at sustainability, the Forum focuses on the way in which science and innovation can be conducted and applied to meet human needs while preserving the life support systems of the planet. It highlights people and programs that are studying nature-society interactions and applying the resulting knowledge to create a sustainability transition around the world."

NY Times Environment Section Online

The Times Science section has a new Environment subsections that is a clearinghouse for a number of different ecology and sustainability articles.

The World Technology podcast

PRI and the BBC's regular radio program, The World regularly features a technology report. Many of these reports deal with sustainability, new technologies, and green issues. Their technology podcast conveniently packages them all in short audio programs which are all available for download at their website.

Some highlights below:


Who needs a car that goes over 25 mph anyhow? The all-electric car is back! What's so great about biofuels? Oil issues in Iraq an Russia. Checking in with the Iraqi blogger Riverbend. And two stories about HIV in Mexico and South Africa. Download mp3


The UN’s panel on climate change issues their third report this year: This one looks at what role technology can play. What about ocean sequestration to remove carbon from the air? Will it work? How Germans are slashing energy use. Biofuels in Denmark. A discussion about design concepts to help the other 90 percent. And, the world is moving too fast! (It’s scientifically proven.) Download mp3
A new report from the Intergovernmental Panel on Climate Change looks at the impacts of global warming. This podcast explores how climate change is affecting our world: from Africa, to South America, to Europe. And what global warming could mean in your neck of the woods. Download mp3

The power of the ocean: Wave Energy takes off in Portugal. A high-tech solution to, sadly, abandoned babies in Italy. Work from home? Ever get lonely? No longer the case in France. And cars are catching on in Vietnam. Download mp3
Gas hydrates... hot new fuel source or environmental menace? A blanket of pollution covers a village in rural China. And the role of immigration in American hi-tech startups. Plus the return of The Plastic People of the Universe. Download mp3

Desertec

Euro-Supergrid with a EU-MENA-Connection: Sketch of possible infrastructure for a sustainable supply of power to EUrope, the Middle East and North Africa (EU-MENA).

" The Trans-Mediterranean Renewable Energy Cooperation (TREC) is an initiative that campaigns for the transmission of clean power from deserts to Europe. Since it was founded in 2003 by The Club of Rome, the Hamburg Climate Protection Foundation and the National Energy Research Center of Jordan (NERC), it has developed the DESERTEC Concept and researched it in cooperation with the German Aerospace Center (DLR). Now TREC is making this concept a reality in cooperation with people in politics, industry and the world of finance.

The DESERTEC Concept of TREC is to boost the generation of electricity and desalinated water by solar thermal power plants and wind turbines in the Middle East and North Africa (MENA) and to transmit the clean electrical power via High Voltage Direct Current (HVDC) transmission lines throughout those areas and as from 2020 (with overall just 10-15% transmission losses) to Europe. The technologies that are needed to realise the DESERTEC concept are already developed and some of them have been in use for decades. Several studies by the German Aerospace Center (DLR) confirm the viability of this concept and the usefulness of realising it very soon."
