Vortex Bladeless wind turbines generate electricity from the vibration
Posted by Shailesh Prasad in categories: solar power, sustainability
Wind farms certainly allow for the production of clean energy. Although they are 100% renewable, they still have problems. They have high costs, disfigure the landscape, produce noise pollution, and above all, have a heavy impact on fauna, and in particular on birds.
The Spanish startup Vortex Bladeless has developed a bladeless turbine that can revolutionize wind energy, especially at the household level, and become the alternative to solar panels. The design of the Spanish firm has already received the approval of Norway’s state energy company, Equinor.

Caltech’s New Space-Based Solar Project Could Power Our Entire Planet /
Posted by Jason Blain in categories: solar power, space, sustainability
It’s the stuff of science fiction: Solar panels in space that beam power directly to Earth equipping the planet with clean renewable and affordable energy. Yet, it could soon be reality.
Caltech has just received $100 million in funding for their Space Solar Power Project (SSPP). The project is described by Caltech as: “Collecting solar power in space and transmitting the energy wirelessly to Earth through microwaves enables terrestrial power availability unaffected by weather or time of day. Solar power could be continuously available anywhere on earth.”
“This ambitious project is a transformative approach to large-scale solar energy harvesting for the Earth that overcomes this intermittency and the need for energy storage,” said SSPP researcher Harry Atwater in the Caltech press release on the matter.

Technology is shaping the future of food but practices rooted in tradition could still have a role to play
Posted by Genevieve Klien in categories: business, food, sustainability
Discussions about how and where we produce food are set to continue for a long time to come as businesses, governments and citizens try to find ways to create a sustainable system that meets the needs of everyone.
It’s perhaps no surprise then that some of the topics covered above are starting to generate interest among the investment community.
Speaking to CNBC’s “Squawk Box Europe” in June, Morgan Stanley’s global head of sustainability research, Jessica Alsford, highlighted this shift.

Rust? Trains? Why clean energy is turning to exotic ideas to fix its storage problem
Posted by Jason Blain in categories: energy, sustainability, transportation
Energy storage ideas.
Mateo Jaramillo sees the future of renewable energy in thousands of iron pellets rusting away in a laboratory in Somerville, Massachusetts.
Jaramillo is chief executive of Form Energy, a company that recently announced what it says is a breakthrough in a global race: how to store renewable energy for long periods of time.

U.S. Navy is developing a solar-powered plane that can fly for 90 days straight
Posted by Jason Blain in categories: solar power, sustainability, transportation
The aircraft, evocatively called Skydweller and built by a U.S.-Spanish aerospace firm Skydweller Aero, could help the Navy keep a watchful eye on the surrounding seas while escorting ships months at a time or act as a communications relay platform. The company was awarded a $5 million contract by the U.S. Navy to develop the aircraft.
To stay airborne for so long, the pilotless craft would have 2900sq ft of solar cells on its wings.

Accelerating norway towards a low-carbon economy — bjørn kjærand haugland, co-founder and CEO, skift.
Bjørn Haugland is the co-founder and Chief Executive Officer of SKIFT Business Climate Leaders (https://www.skiftnorge.no/english), a Norwegian business-led climate initiative with a mission to accelerate the transition to a low-carbon economy and support the government in delivering on its national climate commitments by 2030. The coalition hopes to demonstrate, to businesses and the government, the business potential that exists in the low-carbon economy and help drive the transition.

Using graphene foam to filter toxins from drinking water
Posted by Genevieve Klien in categories: chemistry, engineering, health, nuclear energy, sustainability
Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits, the element can now be found flowing out of taps worldwide.
In the United States alone, “many areas are affected by uranium contamination, including the High Plains and Central Valley aquifers, which supply drinking water to 6 million people,” says Ahmed Sami Helal, a postdoc in the Department of Nuclear Science and Engineering. This contamination poses a near and present danger. “Even small concentrations are bad for human health,” says Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering.
Now, a team led by Li has devised a highly efficient method for removing uranium from drinking water. Applying an electric charge to graphene oxide foam, the researchers can capture uranium in solution, which precipitates out as a condensed solid crystal. The foam may be reused up to seven times without losing its electrochemical properties. “Within hours, our process can purify a large quantity of drinking water below the EPA limit for uranium,” says Li.

Why Not Turn Airports Into Giant Solar Farms?
Posted by Jason Blain in categories: solar power, sustainability, transportation
Airports have vast swaths of empty land and rooftops. But it’s not so easy as just covering everything with solar panels.

Converting tamarind shells into an energy source for vehicles
Posted by Omuterema Akhahenda in categories: energy, food, sustainability
Shells of tamarind, a tropical fruit consumed worldwide, are discarded during food production. As they are bulky, tamarind shells take up a considerable amount of space in landfills where they are disposed as agricultural waste.
However, a team of international scientists led by Nanyang Technological University, Singapore (NTU Singapore) has found a way to deal with the problem. By processing the tamarind shells which are rich in carbon, the scientists converted the waste material into carbon nanosheets, which are a key component of supercapacitors — energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.
The study reflects NTU’s commitment to address humanity’s grand challenges on sustainability as part of its 2025 strategic plan, which seeks to accelerate the translation of research discoveries into innovations that mitigate our impact on the environment.
