Secrets of fluorescent microalgae could lead to super-efficient solar cells
Posted by Quinn Sena in categories: solar power, sustainability
Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht.
Microalgae are probably the oldest surviving living organisms on the planet. They have evolved over billions of years to possess light harvesting systems that are up to 95 per cent efficient. This enables them to survive in the most extreme environments, and adapt to changes our world has seen over this time-span.
Unravelling how this system works could yield important clues about how it could be used or recreated for use in new, super-efficient organic solar panels. Because of the complexity of the organisms and the huge variety of different species, however, progress in this area has been limited.

Solar Electric Propulsion (SEP)
Posted by James Christian Smith in categories: robotics/AI, solar power, space travel
As NASA seeks cost-effective access to destinations across the inner solar system, including cislunar space and Mars, it also seeks to shorten the cycle of time to develop and infuse transformative technologies that increase the nation’s capabilities in space, enable NASA’s future missions and support a variety of commercial spaceflight activities.
NASA’s Solar Electric Propulsion (SEP) project is developing critical technologies to extend the length and capabilities of ambitious new science and exploration missions. Alternative propulsion technologies such as SEP may deliver the right mix of cost savings, safety and superior propulsive power to enrich a variety of next-generation journeys to worlds and destinations beyond Earth orbit.
Energized by the electric power from on-board solar arrays, the electrically propelled system will use 10 times less propellant than a comparable, conventional chemical propulsion system, such as those used to power the space shuttles to orbit. Yet that reduced fuel mass will deliver robust power capable of propelling robotic and crewed missions well beyond low-Earth orbit — sending exploration spacecraft to distant destinations or ferrying cargo to and from points of interest, laying the groundwork for new missions or resupplying those already underway. Mission needs for high-power SEP are driving the development of advanced technologies the project is developing and demonstrating including large, light-weight solar arrays, magnetically shielded ion propulsion thrusters, and high-voltage power processing units.

5 AI Breakthroughs We’ll Likely See in the Next 5 Years
Posted by Shailesh Prasad in categories: climatology, robotics/AI, solar power, sustainability
Just as the modern computer transformed our relationship with bits and information, AI will redefine and revolutionize our relationship with molecules and materials. AI is currently being used to discover new materials for clean-tech innovations, such as solar panels, batteries, and devices that can now conduct artificial photosynthesis.
Today, it takes about 15 to 20 years to create a single new material, according to industry experts. But as AI design systems skyrocket in capacity, these will vastly accelerate the materials discovery process, allowing us to address pressing issues like climate change at record rates. Companies like Kebotix are already on their way to streamlining the creation of chemistries and materials at the click of a button.
Atomically precise manufacturing will enable us to produce the previously unimaginable.

New type of silicon promises cheaper solar technology
Posted by Quinn Sena in categories: solar power, sustainability
An international research team led by The Australian National University (ANU) has made a new type of silicon that better uses sunlight and promises to cut the cost of solar technology.
The researchers say their world-first invention could help reduce the costs of renewable electricity below that of existing coal power stations, as well as lead to more efficient solar cells.
Senior researcher ANU Professor Jodie Bradby said silicon was used as the raw material for solar cells because of its abundance, low-cost and non-toxicity.

Winters Are Only Going to Get Worse, So Researchers Invented a Way to Generate Electricity from Snowfall
Posted by Genevieve Klien in categories: solar power, sustainability
The farther you get from the equator, the less effective solar panels become at reliably generating power all year round. And it’s not just the shorter spans of sunlight during the winter months that are a problem; even a light dusting of snow can render solar panels ineffective. As a result of global warming, winters are only going to get more severe, but there’s at least one silver lining as researchers from UCLA have come up with a way to harness electricity from all that snow.
The technology they developed is called a snow-based triboelectric nanogenerator (or snow TENG, for short) which generates energy from the exchange of electrons. If you’ve ever received a nasty shock when touching a metal door handle, you’ve already experienced the science at work here. As it falls towards earth, snowflakes are positively charged and ready to give up electrons. In a way, it’s almost free energy ready for the taking, so after testing countless materials with an opposite charge, the UCLA researchers (working with collaborators from the University of Toronto, McMaster University, and the University of Connecticut) found that the negative charge of silicone made it most effective for harvesting electrons when it came into contact with snowflakes.
