Legacy of Biosphere 2 lives on long after original group left enclosure

Posted by in categories: energy, finance, food

ORACLE, Ariz. — They lived for two years and 20 minutes under the glass of a miniature Earth, complete with an ocean, rain forest, desert, grasslands and mangroves. Their air and water were recycled, and they grew the sweet potatoes, rice and other food they needed to survive.

About 1,500 people were invited and some 200 journalists were on hand as the eight original inhabitants of Biosphere 2 left their glass terrarium a quarter-century ago last month in two groups that no longer talked to each other amid the stress of sharing a small space and disputes over how the project should be run. Detractors called the $150 million experiment a failure because additional oxygen was pumped into what was supposed to be a self-sustaining system.

A power struggle in subsequent months led the financial backer, Texas billionaire Edward Bass, to hire investment banker Stephen Bannon, who was later President Trump’s chief strategist, to bring the project back from financial disarray.

Cleanup Begins After Ships Collide Causing Fuel Spill in Mediterranean Sea

Posted by in categories: energy, transportation

  • A pair of merchant ships collided causing a fuel spill in the Mediterranean Sea.
  • No injuries were reported in the collision.
  • French and Italian authorities are working to contain the spill.

French and Italian maritime authorities ays they have begun cleaning up a fuel spill that has spread 12.5 miles in the Mediterranean Sea after two cargo ships collided north of the island of Corsica.

Italy’s coast guard said Monday it’s recovering some of the polluted material and monitoring the spill amid changing weather conditions.

China to train African scientists as part of $60-billion development plan

Posted by in categories: energy, policy, transportation

But some policy experts and scientists worry that African nations might become too reliant on other countries to provide training. Others doubt that the initiatives will truly boost African science, as similar projects planned at past forums have yet to produce noticeable benefits.


But critics worry the investment will make African countries too reliant on an outside power.

Mechanical engineers develop ways to improve windfarm productivity

Posted by in categories: energy, sustainability

You’ve probably seen them, perhaps on long roadtrips: wind turbines with enormous, hypnotic rolling blades, harnessing the clean power of wind for conversion into electric energy. What you may not know is that for the explosion in the number of wind turbines in use as we embrace cleaner sources of energy, these wind farms are quite possibly not as productive as they could be.

“We’ve been designing turbines for use by themselves, but we almost never use them by themselves anymore,” said UC Santa Barbara mechanical engineering professor Paolo Luzzatto-Fegiz, whose specialty lies in fluid mechanics. Historically, he said, were used individually or in small groups, but as the world moves toward greener technologies, they are now found in groups of hundreds or thousands.

The problem with these large installations is that each machine, which has been designed to extract as much energy as possible from oncoming , may not “play well” with the others, Luzzatto-Fegiz explained. Depending on how the turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow.

Flowing salt water over this super-hydrophobic surface can generate electricity

Posted by in categories: energy, engineering, sustainability

Engineers at the University of California San Diego have developed a super-hydrophobic surface that can be used to generate electrical voltage. When salt water flows over this specially patterned surface, it can produce at least 50 millivolts. The proof-of-concept work could lead to the development of new power sources for lab-on-a-chip platforms and other microfluidics devices. It could someday be extended to energy harvesting methods in water desalination plants, researchers said.

A team of researchers led by Prab Bandaru, a professor of mechanical and aerospace engineering at the UC San Diego Jacobs School of Engineering, and first author Bei Fan, a graduate student in Bandaru’s research group, published their work in the Oct. 3 issue of Nature Communications.

The main idea behind this work is to create electrical by moving ions over a charged . And the faster you can move these ions, the more voltage you can generate, explained Bandaru.

Humanities and scientific explanation: the need for change

Posted by in categories: education, energy

For too long, presentations of science for the general public, and education in schools, has suggested that science wields a sort of hegemonic power, as if its terms and methods gradually replace and make redundant all other discourse; the only reason it has not yet completed its conquest is that the world is complicated—but it is only a matter of time…
