New technique accurately measures how 2D materials expand when heated
Posted by Saúl Morales Rodriguéz in categories: computing, particle physics, solar power, sustainability
Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells, LEDs, and other devices that run faster and perform better.
One issue holding back these next-generation electronics is the heat they generate when in use. Conventional electronics typically reach about 80 degrees Celsius, but the materials in 2D devices are packed so densely in such a small area that the devices can become twice as hot. This temperature increase can damage the device.
This problem is compounded by the fact that scientists don’t have a good understanding of how 2D materials expand when temperatures rise. Because the materials are so thin and optically transparent, their thermal expansion coefficient (TEC)—the tendency for the material to expand when temperatures increase—is nearly impossible to measure using standard approaches.

ESA SOLARIS: Wireless Power Beamed Down From Space
Posted by Kelvin Dafiaghor in categories: business, government, solar power, space, sustainability
Solar power could be gathered far away in space and transmitted wirelessly down to Earth to wherever it is needed. The European Space Agency (ESA) plans to investigate key technologies needed to make Space-Based Solar Power a working reality through its SOLARIS initiative. Recently in Germany, one of these technologies, wireless power transmission, was demonstrated to an audience of decision-makers from business and government.
The demonstration took place at Airbus’ X-Works Innovation Factory in Munich. Microwave beaming was used to transmit green energy between two points representing ‘Space’ and ‘Earth’ over a distance of 36 meters.

Arizona town looks for solutions amid Western water crisis
Posted by Genevieve Klien in category: sustainability
Drive just North of Scottsdale, Arizona, and you’ll find a loose grid of dirt roads known as the Rio Verde Foothills. It’s home to around 2,000 families drawn to rustic desert beauty and the freedom of living outside the city limits, but the town is about to become a symbol of the West’s growing water crisis.
John Hornewer moved to the area 23 years ago. When he discovered his new community didn’t have water service, he began hauling water for himself, along with some of his neighbors.
“As my neighbor saw me coming up the road with the trailer, they were like, ‘Hey, could you stop and drop off a load for me?’” Hornewer said.

Recreating photosynthesis for unlimited hydrogen energy

“I believe that water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light, of an intensity of which coal is not capable.” – Jules Verne, The Mysterious Island (1874).
We have come a long way since science fiction writer Jules Verne wrote this visionary sentence, but hydrogen has still not emerged as a major source of energy. ESA is setting out to change this through the latest Open Space Innovation Platform (OSIP) call for ideas.

Algae-filled panels could generate oxygen and electricity while absorbing CO2
Posted by Quinn Sena in categories: electronics, sustainability
Greenfluidics, a Mexico-based startup, promises newer, greener bio panels that can provide fresh oxygen and considerably bring down your power consumption while also delivering biomass-based fuel to you, New Atlas has reported.
With the world trying to reduce carbon emissions, algae have taken quite the center stage in capturing the carbon dioxide being released. From using algal blooms as large carbon capture sites to even powering electronic devices using algae, researchers are trying to use these green organisms everywhere.

Artificial Photosynthesis Advance: Standalone Device Converts Sunlight, CO2 and Water Into Clean Fuel
Posted by Quinn Sena in categories: solar power, sustainability
Researchers have developed a standalone device that converts sunlight, carbon dioxide, and water into a carbon-neutral fuel, without requiring any additional components or electricity.
The device, developed by a team from the University of Cambridge, is a significant step toward achieving artificial photosynthesis.
Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.
