US startup ditches towers for pyramid-mounted turbines that dance with wind

Posted by in categories: energy, sustainability

An innovative floating offshore wind turbine prototype was launched in New Bedford, Massachusetts this week. Instead of a single anchor tower, the approach uses a pyramid base that can also passively orient itself in the direction of the blowing wind.

As wind turbines get bigger and sweep larger areas in a single rotation, wind farms move offshore to gain maximum advantage from powerful sea winds. Over the years, the costs of wind-based energy have been plummeting, but as wind farms are set up farther into the sea, the costs and time required to set up new wind farms are bound to increase.

Simple, sustainable path unlocked to long-sought superior carbon nanotube materials

Posted by in categories: energy, nanotechnology, sustainability

Carbon nanotubes have long tantalized researchers with their extraordinary mechanical and electronic properties. As one-dimensional nanostructures with remarkable mechanical strength and electrical conductivity, CNTs have been eyed for next-generation composites, energy storage devices, sensors and more. Yet realizing their promise has proven an enduring challenge.

CNTs have ultra-high surface energy and readily form large bundles rather than remaining as individualized tubes, severely compromising resultant material properties. Exfoliating these bundles, particularly in solution, has remained an immense difficulty despite intense R&D efforts over 30+ years employing covalent and noncovalent functionalization strategies.

Covalent approaches disrupt the CNTs’ pristine sp2 carbon networks, damaging their intrinsic properties. Noncovalent methods like surfactants and polymers have had limited success in debundling smaller diameter single-wall CNTs (SWCNTs), especially longer high aspect ratio tubes preferred for optimal conductivity and strength. And virtually all tactics have struggled to exfoliate specific SWCNT types, hindering enrichment in metallic SWCNTs boasting far higher conductance than their semiconducting counterparts.

Applying MXene to quantum dot photovoltaic cells simultaneously increases efficiency and stability

Posted by in categories: engineering, quantum physics, solar power, sustainability

A research team led by Professor Jong-min Choi of the Department of Energy Engineering has developed a technology that can significantly improve the efficiency of quantum dot photovoltaic cells by introducing organic solvent dispersible MXene.

The findings were published in Advanced Energy Materials (“Organic solvent dispersible MXene integrated colloidal quantum dot photovoltaics”).

One Step Closer to Living on Mars: AI Unlocks Secrets of Oxygen Production on the Red Planet

Posted by in categories: chemistry, robotics/AI, solar power, space, sustainability

Immigration to and living on Mars have often been themes in science fiction. Before these dreams can become reality, humanity faces significant challenges, such as the scarcity of vital resources like oxygen needed for long-term survival on the Red Planet. Yet, recent discoveries of water activity on Mars have sparked new hope for overcoming these obstacles.

Scientists are now exploring the possibility of decomposing water to produce oxygen through electrochemical water oxidation driven by solar power with the help of oxygen evolution reaction (OER) catalysts. The challenge is to find a way to synthesize these catalysts in situ using materials on Mars, instead of transporting them from the Earth, which is of high cost.

Earth Itself May Be an Intelligent Being, Suggests New Theory

Posted by in categories: alien life, climatology, sustainability

This was suggested by Gustave Fechner and other philosophers.


How about planets? Can they have minds? This idea, that planets are also conscious beings, seems to be at the heart of a new theory put forth by astrobiologists. The premise of this thought experiment is that bacteria and plants working together have altered planets like Earth, giving them a new lease on life.

This research, published in the International Journal of Astrobiology, provides a scale by which planets’ intelligence can be evaluated. It’s shocking to consider an extraterrestrial organism intelligent rather than a sentient animal like a human. But in a way, a planet can have a “green mind”; this paradigm suggests novel approaches to coping with climate change, technological upheaval, and other emergencies.

The Pursuit of Perfection: Ultimate Mid-Infrared Mirror Achieves 99.99923% Reflectivity

Posted by in categories: climatology, sustainability

Advanced infrared mirrors enhance climate and biofuel research via precision trace gas sensing.

An international team of researchers from the United States, Austria, and Switzerland has demonstrated the first true supermirrors in the mid-infrared spectral region. These mirrors are key for many applications, such as optical spectroscopy for environmental sensing, as well as laser cutting and welding for manufacturing.
