“The construction of the storage went well, especially considering that the solution is completely new,” said Polar Night co-founder and chief technology officer Markku Ylönen in a statement.
“We managed to get everything in order despite some challenges and a short delay.”
He said the first installation has shown that the system “has even more potential than we initially calculated”.
A non-volatile silicon photonics switch based on phase-change materials actuated by graphene heaters shows a switching energy density that is within an order of magnitude of the fundamental thermodynamic limit.
Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University have developed a gentler, more precise technique using low-power visible light.

Did you know that the best kind of armour is the one that is already vaporised?
Hello, I’m Todd and this is AsteronX.
Today we’re going to be discussing real energy shields, and even propose one, maybe two, of our own concepts.
Armour, regardless of whether its protecting against weaponry or the hazards of space travel in general, is limited by its melting and vaporisation temperatures.
Theory underpins our understanding of convection in the Earth’s outer core and its function in controlling the planet’s magnetic field. Convective flows or how they may be changing have never been directly observed by scientists. Virginia Tech geoscientist Ying Zhou puts proof forward for the first time.
A large earthquake shook the Kermadec Islands region in the South Pacific Ocean in May 1997. A little over 20 years later, in September 2018, a second big earthquake hit the same location, with its waves of seismic energy emanating from the same region.
Although two decades separated the earthquakes, because they occurred in the same region, they’d be expected to send seismic waves through the Earth’s layers at the same speed, said Ying Zhou, a geoscientist with the Department of Geosciences at the Virginia Tech College of Science.
Spotted: Although relatively expensive to produce at present, and with storage often cited as a concern, green hydrogen fuel production is increasing. A naturally occurring and superabundant element, hydrogen is popular for several reasons, including the ability to produce it using renewable energy sources. And now, Element 1’s modular, grid-independent hydrogen generation technology is making the fuel even more accessible.
Designed to efficiently convert methanol to hydrogen to electricity, the technology supports both hydrogen fuel cell vehicles and electric vehicles. The company’s catalytic reactor heats a methanol and water feedstock mix before sending it through a membrane purifier for almost 100 per cent fuel cell grade hydrogen.
Because the modular system produces the fuel as needed, the risk of combustion is nearly eliminated, and specialty storage facilities are redundant. This is because the only material that needs to be stored and transported is the methanol and water feedstock. The hydrogen is then produced on-site. Element 1 provides both small and large-scale solutions, as well as a mobile version specifically for refuelling electric vehicles on the go.
Global Link Information Network was founded in 1995 by Elon Musk, his brother Kimbal Musk, and Greg Kouri who provided $6,000 in funding. Elon famously dropped out of pursuing a PhD at Stanford in energy physics/material science two days into the program to pursue the opportunity. Global Link Information Network was later renamed as Zip2 and served as a directory for local businesses. In 1996, Zip2 starts pulling data from American Business Information Inc. (ABI) and starts a self-comparison to yellow pages that will continue throughout its lifespan as a brand.
A timeline showing Elon Musk’s first website (Zip2) and its evolutions over the years, starting from 1996 and ending in 2004.
Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up …
Space is a deep, dark, vast abyss that exists between the cosmos, separating them from each other. But is it truly as empty as we think it is? Or is the vacuum that spans everywhere hiding something from us? Something mysterious, and perhaps the most powerful source of energy?
Zero-point energy, also known as vacuum energy, has been touted as a potentially limitless and ubiquitous source of energy, if one could only find the means to harness it.
Welcome to Factnomenal and today we’re looking at the facts and demystifying the most mysterious energy in the universe.
