A new “molten salt” battery could store cheap, renewable energy year round

Posted by in categories: climatology, sustainability

Scientists at the US Department of Energy have created a low-cost molten salt battery that can store energy for months — potentially giving us a way to store and use energy from renewables year round.

The challenge: To stop climate change, we need to transition toward cleaner sources of energy.

Renewable energy (especially wind and solar) has become increasingly cheap to generate over the last couple decades, but storage is still an issue — we can burn as much coal or gas as we want, whenever we need it, but we can’t force the wind to blow.

E-Space sheds more light on sustainable megaconstellation plan

Posted by in categories: satellites, sustainability

COLORADO SPRINGS — Megaconstellation startup E-Space is preparing to deploy the first of potentially hundreds of thousands of satellites on a Rocket Lab mission slated for no earlier than April 19.

Three E-space prototypes are part of the 34 payloads that Rocket Lab said April 5 are on the upcoming mission, including satellites for Alba Orbital, Astrix Astronautics, Aurora Propulsion Technologies, Unseenlabs and Swarm Technologies.

Rocket Lab will also attempt a mid-air helicopter capture of its Electron launch vehicle for the first time after the flight. The launch is set to commence within a 14-day window starting on April 19 and represents a major step in Rocket Lab’s plans to make the rocket reusable.

Canada’s Environment Ministry Approves Offshore Oil Project While Touting 2030 Emissions Reduction Plan

Posted by in categories: climatology, government, neuroscience, sustainability

Cognitive dissonance in the government’s decision to approve Bay-du-Nord while professing to fight fossil fuel emissions responsible for climate change.


The decision to approve Bay-du-Nord is based on the low emissions intensity of the oil that will be produced with no accounting for end-use.

Solar panels created from crop waste produce energy even if the sun isn’t shining

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

The British James Dyson Foundation presented the first Sustainability Award to Carvey Ehren Maigue, an electrical engineering student in the Philippines. He was awarded for creating new material from recycled crop waste that has the ability to transform ultraviolet (UV) rays from the sun into electrical energy. The technology could soon be turning the windows and walls of buildings into a rich new source of electricity.

The invention of the Filipino university student is called AuREUS (Aurora Renewable Energy and UV Sequestration). Both AuREUS devices (Borealis Solar Window and Astralis Solar Wall) use the same technology used in the beautiful Northern and Southern lights. High energy particles are absorbed by luminescent particles that re-emit them as visible light. A similar type of luminescent particles (derivable from certain fruits and vegetables) were suspended in a resin substrate and is used as the core technology on both devices.

Sunflower pollen-based paper that you can print on and unprint

Posted by in categories: particle physics, sustainability

In a world where deforestation directly leads to biodiversity loss, disrupts the water cycle, and alters rainfall, looking for alternatives to recycle or produce paper is more important than ever.

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a pollen-based paper that, after being printed, can be erased and reused multiple times without any damage to the paper.

Could ‘hot carrier’ solar cells break the theoretical efficiency limit?

Posted by in categories: solar power, sustainability

Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.

Honey might be the key to cooler, more efficient, biodegradable chips

Posted by in categories: computing, engineering, neuroscience, sustainability

These chips might be the future of neuromorphic computing.


Honey could be the next material used to create brain-like computer chips. Its proven practicality marks another step toward creating efficient, renewable processors for neuromorphic computing systems, using biodegradable products.

Research engineers from WSU’s School of Engineering and Computer Science, Feng Zhao and Brandon Sueoka, first processed honey into a solid. Then they jammed it between two electrodes, using a structure design similar to that of a human synapse. They’re known as ‘memristors,’ and are proficient at learning and retaining information just like human neurons.

West Virginia’s largest solar farm will sit on a former coal mining site

Posted by in category: sustainability

West Virginia’s largest solar farm will sit on the site of the 5,800-acre Hobet Mine, one of the state’s largest former coal mines, which went bankrupt in 2015.

The solar farm will be situated on 3,000 acres of the site, which straddles Boone and Lincoln counties in the southwestern part of the state, near Charleston. It will power an adjacent 2,800-acre site that will host industry, lodging, hospitality, and recreation, and the whole site will be known as SunPark. The solar farm is the first phase of the project.

Materials come alive

Posted by in categories: bioengineering, biological, robotics/AI, sustainability

The dissemination of synthetic biology into materials science is creating an evolving class of functional, engineered living materials that can grow, sense and adapt similar to biological organisms.

Nature has long served as inspiration for the design of materials with improved properties and advanced functionalities. Nonetheless, thus far, no synthetic material has been able to fully recapitulate the complexity of living materials. Living organisms are unique due to their multifunctionality and ability to grow, self-repair, sense and adapt to the environment in an autonomous and sustainable manner. The field of engineered living materials capitalizes on these features to create biological materials with programmable functionalities using engineering tools borrowed from synthetic biology. In this focus issue we feature a Perspective and an Article to highlight how synergies between synthetic biology and biomaterial sciences are providing next-generation engineered living materials with tailored functionalities.
