Engineers develop a simple way to desalinate water using solar energy

Posted by in categories: solar power, sustainability

Distillation of water using solar energy is considered one of the most popular desalination methods today.

Power engineers at Ural Federal University (UrFU), together with colleagues from Iraq, have developed a new desalination technology, which is claimed to be much more effective than others, by incorporating a rotating cylinder. The method proposed by the UrFU power engineers will significantly reduce the cost of desalination and will increase production volumes by four times.

The experimental new solar distiller incorporates a rectangular basin, inside of which is a horizontally oriented black steel cylinder. The basin is filled with undrinkable water, and the cylinder is slowly rotated by a solar-powered DC motor.

World’s first home hydrogen battery powers an average home for two days

Posted by in categories: business, chemistry, mobile phones, solar power, sustainability

The Australian company LAVO has developed a hydrogen storage system for domestic solar systems. It is the world’s first integrated hybrid hydrogen battery that combines with rooftop solar to deliver sustainable, reliable, and renewable green energy to your home and business. Developed in partnership with UNSW, Sydney, Australia, and Design + Industry, the Hydrogen Battery System from LAVO consists of an electrolysis system, hydrogen storage array, and fuel cell power system rolled into one attractive cabinet. When the electricity from the solar system on the roof is not needed, it is stored in the form of hydrogen. This then serves as fuel for the fuel cell when the solar system is not supplying electricity.


However, LAVO’s hydrogen hybrid battery delivers a continuous output of 5 kW and stores over 40kWh of electricity – enough to power the average Australian home for two days on a single charge. The system is designed to easily integrate with existing solar panels, creating a significant opportunity for LAVO to have an immediate and notable impact. There are Wi-Fi connectivity and a phone app for monitoring and control, and businesses with higher power needs can run several in parallel to form an intelligent virtual power plant.

Hydrogen is often incorrectly seen as an unsafe fuel, usually due to the 1937 Hindenburg disaster. However, the company says any leaks will disperse quickly, though, making it inherently no more dangerous than other conventional fuels such as gasoline or natural gas. This innovation has a lifespan of approximately 30 years, which is three times longer than that of lithium batteries, thanks to its reliance on hydrogen gas rather than the chemicals in a conventional battery.

Axion dark matter detection

Posted by in categories: cosmology, materials

O,.o circa 2017.


We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The local axion dark matter field shall drive transitions between Zeeman-split atomic levels separated by the axion rest mass energy m a.

C.
2. Axion-related excitations are then detected with an upconversion scheme involving a pump laser that converts the absorbed axion energy (~hundreds of μeV) to visible or infrared photons, where single photon detection is an established technique. The proposed scheme involves rare-earth ions doped into solid-state crystalline materials, and the optical transitions take place between energy levels of 4f.

Google’s time crystal discovery is so big, we can’t fully comprehend it

Posted by in categories: computing, mobile phones, quantum physics

Forget Google Search and Fuchsia. Researchers from Google, Stanford, Princeton, and other universities might have made a computer discovery so big we can’t fully comprehend it yet. Even Google researchers aren’t entirely sure that their time crystal discovery is valid. But if it turns out to be accurate, then Google might be one of the first companies to give the world a crucial technological advancement for the future. Time crystals will be an essential building block in quantum computers, the kind of computers that can solve complex problems with incredible speed and power technologies that aren’t even invented.

What is a quantum computer?

Google isn’t the only company building quantum computers, and these types of machines keep popping up in the news with regularity. Quantum computers won’t reach your phone, and they’re not going to play games. Even if they did, Nintendo will totally ignore the latest computer technology when designing future consoles.

This firefly-inspired Husqvarna bike balances the comfort of car with the thrill of biking!

Posted by in category: transportation

Imagining how the dimension of mobility will evolve in the next few years, Haochen gives his imagination wings in the shape of this firefly-inspired Husqvarna Devil S Concept bike.

More often than not, motorbikes are tagged as unsafe since they expose the rider’s body to high-speed dangers in case of an accident. Two-wheelers typically have a very open stance that attracts the young generation and adds to the adrenaline rush. More than anything, the ride should be stylish and match the fashion statement of the young crowd. This inspired Haochen (Wenson) Wei to design a motorbike with a very stylish character and a safe design that’s radically different from what bikes are perceived to be.

Sergey Young: breaking the barrier of maximum lifespan

Posted by in categories: biotech/medical, life extension, robotics/AI

The news we like: “In five to 10 years time from now, we’ll have a new, special kind of drugs: longevity drugs. And unlike today’s medication, which always focused on one disease, this kind of drug will will give us an opportunity to influence aging as a whole and a very fatalistic way, working on healthspan, not only on lifespan… it’s very likely that this new drug will be developed with the help of artificial intelligence, which will compress drug development cycle by two or three times from what they are today.”


Ahead of the launch of his new book Growing Young, Sergey Young joins us for a video interview to discuss longevity horizons, personal health strategies and disruptive tech – and how we are moving towards radically extending our lifespan and healthspan.

Sergey Young, the longevity investor and founder of the Longevity Vision Fund is on a mission to extend healthy lifespans of at least one billion people. His new book, Growing Young, is released on 24th August and is already rising up the Amazon charts.

The Future of Deep Learning Is Photonic

Posted by in categories: robotics/AI, transportation

Over the years, deep learning has required an ever-growing number of these multiply-and-accumulate operations. Consider LeNet, a pioneering deep neural network, designed to do image classification. In 1998 it was shown to outperform other machine techniques for recognizing handwritten letters and numerals. But by 2012 AlexNet, a neural network that crunched through about 1600 times as many multiply-and-accumulate operations as LeNet, was able to recognize thousands of different types of objects in images.

Advancing from LeNet’s initial success to AlexNet required almost 11 doublings of computing performance. During the 14 years that took, Moore’s law provided much of that increase. The challenge has been to keep this trend going now that Moore’s law is running out of steam. The usual solution is simply to throw more computing resources—along with time, money, and energy—at the problem.

As a result, training today’s large neural networks often has a significant environmental footprint. One 2019 study found, for example, that training a certain deep neural network for natural-language processing produced five times the CO2 emissions typically associated with driving an automobile over its lifetime.

This Miniature Particle Accelerator Powers a Tiny Laser With Huge Promise

Posted by in categories: particle physics, space

Particle accelerators are hugely important in the study of the matter of the Universe, but the ones we think of tend to be gigantic instruments – surrounding cities in some cases. Now scientists have made a much smaller version to power an advanced laser, a setup that could be just as useful as its larger counterparts.

The particle accelerator in question is a plasma wakefield accelerator, which generates short and intense bursts of electrons, and the laser it’s powering is what’s known as a free-electron laser (FEL), which uses its light to analyze atoms, molecules, and condensed matter in incredibly high resolutions.

While this scenario has been tried before, the resulting laser light hasn’t been intense enough to be useful at smaller scales. Here, the researchers were able to keep the setup enclosed in few normal-sized rooms while amplifying the final electron beam produced by the laser, increasing the intensity by 100 times in the last step of the process.
