Today a state-of-the-art solar panel on Earth can convert between 20 to 30% of the energy it collects from sunlight into electricity. At night solar panels here contribute nothing. But in space with nothing to block the Sun, that same Earth-based solar panel becomes thirteen times more efficient. And that is enough of an incentive to consider solar power from space.

The Chinese and UK models are massive arrays located in geosynchronous orbit while continuously beaming energy to receiving stations here on Earth.

The US model is different using a constellation of solar power generating satellites. These would be in relatively low orbits and interconnected to form a mesh network. The total network would generate continuous energy beaming it to the surface even when a portion of it gets blocked when the satellites enter the night side of the planet.

According to The Guardian, there’s a team of researchers in northern Greece who have spent the last few years experimenting with ways to harvest metal though agriculture:

In a remote, beautiful field, high in the Pindus mountains in Epirus, they are experimenting with a trio of shrubs known to scientists as “hyperaccumulators”: plants which have evolved the capacity to thrive in naturally metal-rich soils that are toxic to most other kinds of life. They do this by drawing the metal out of the ground and storing it in their leaves and stems, where it can be harvested like any other crop. As well as providing a source for rare metals – in this case nickel, although hyperaccumulators have been found for zinc, aluminium, cadmium and many other metals, including gold – these plants actively benefit the earth by remediating the soil, making it suitable for growing other crops, and by sequestering carbon in their roots. One day, they might supplant more destructive and polluting forms of mining.

Imagine, finding a way to pull minerals out of the Earth … without violent colonization and destructive mining practices. Maybe us lowly humans could learn a thing or two from the flowers!

NVIDIA has published the source code of its Linux kernel modules for the R515 driver, allowing developers to provide greater integration, stability, and security for Linux distributions.

The source code has been published to NVIDIA’s GitHub repository under a dual licensing model that combines the GPL and MIT licenses, making the modules legally re-distributable.

The products supported by these drivers include all models built on the Turing and Ampere architecture, released after 2018, including the GeForce 30 and GeForce 20 series, the GTX 1,650 and 1,660, and data center-grade A series, Tesla, and Quadro RTX.

The Verge TS isn’t just a proper hubless, electric motorbike. It also comes with an insane 1,000 Nm of torque. property= description.

Scientists at the Max Planck Institute for the Science of Light (MPL) and Max-Planck-Zentrum für Physik und Medizin (MPZPM) in Erlangen present a large step forward in the characterization of nanoparticles. They used a special microscopy method based on interfereometry to outperform existing instruments. One possible application of this technique may be to identify illnesses.

Nanoparticles are everywhere. They are in our body as protein aggregates, lipid vesicles, or viruses. They are in our drinking water in the form of impurities. They are in the air we breath as pollutants. At the same time, many drugs are based on the delivery of nanoparticles, including the vaccines we have recently been given. Keeping with the pandemics, quick tests used for the detection the SARS-Cov-2 are based on nanoparticles too. The red line, which we monitor day by day, contains myriads of gold nanoparticles coated with antibodies against proteins that report infection.

Technically, one calls something a nanoparticle when its size (diameter) is smaller than one micrometer. Objects of the order of one micrometer can still be measured in a normal microscope, but particles that are much smaller, say smaller than 0.2 micrometers, become exceedingly difficult to measure or characterize. Interestingly, this is also the size range of viruses, which can become as small as 0.02 micrometers.

Canadian company Aurea has developed a portable wind turbine that fits in your backpack. Called Shine, it weighs just three pounds, it’s about the size of a water bottle, and it can charge any USB device, or up to four phones (though not at the same time). The turbine is shaped a bit like a mini Zeppelin. It features three gently curved blades that fold out like flower petals and a collapsible tripod that is stored inside. The product launched on Kickstarter last year and on Indigogo last week. It has raised over $270,000 so far and will be shipping in a matter of months–just in time for camping season.

Humans have been harnessing the wind for centuries, but it has always required massive infrastructure, be it windmills or wind turbines. In recent years, engineers and designers alike have taken it upon themselves to reinvent the technology by playing with scale and form (think wind turbines integrated into walls or giant grids made of tiny turbines). But Aurea’s founders had a different goal in mind: Make wind power portable.

Shine can be used during a blackout at home, and serve anyone who needs access to energy while not attached to the grid. But its most likely users are going to be campers, RVers, and nomads, making weight a crucial factor. “People said, ‘We won’t carry it if it weighs more than three pounds,’” says Cat Adaley, a mechanical engineer who founded Aurea in 2017 and developed Shine with entrepreneur Rachel Carr. “Every design feature was weighed.” (The battery makes up a third of the weight, and the turbine is made of polycarbonate reinforced plastic with a glass composite; the tripod is aluminum.) All of this helped the founders create a portable turbine that has the highest power to weight ratio of any renewable energy at this scale, Adaley says.
