Extra salty sodium battery performs on par with lithium

Posted by in categories: chemistry, energy

Batteries that use a sodium-ion chemistry rather than the commonplace lithium-ion could offer a number of advantages, owing to the cheap and abundant nature of the element. Scientists at Washington State University have come up with a design billed as a potential game changer in this area – a sodium-ion battery offering a comparable energy capacity and cycling ability to some lithium-ion batteries already on the market.

In a way, sodium-ion batteries function just like lithium-ion batteries, generating power by bouncing ions between a pair of electrodes in a liquid electrolyte. One of the problems with them in their current form, however, is that while this is going on inactive sodium crystals tend to build up on the surface of the negatively-charged electrode, the cathode, which winds up killing the battery. Additionally, sodium-ion batteries don’t hold as much energy as their lithium-ion counterparts.

“The key challenge is for the battery to have both high energy density and a good cycle life,” says Washington State University’s Junhua Song, lead author on the paper.

Bitcoin Could Be About To Surge To $100,000 After Stock-To-Flow Update Revealed

Posted by in category: bitcoin

Bitcoin has been struggling to break over the $10,000 per bitcoin level since its highly-anticipated supply squeeze —but that could be about to change.

The bitcoin price, up around 30% since the beginning of the year and on track to be one of the year’s best performing assets, has swung wildly over the last few months.

Now, one of the most closely-watched bitcoin analysts, an anonymous strategist who claims to be a member of an institutional investment team that manages around $100 billion in assets, has released an update to his so-called stock-to-flow model, suggesting the bitcoin price could be about to surge to around $100,000.

Study finds that patterns formed by spiral galaxies show that the universe may have a defined structure

Posted by in categories: computing, space

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links might suggest that the early universe could have been spinning, according to a Kansas State University study.

Lior Shamir, a K-State computational astronomer and computer scientist, presented the findings at the 236th American Astronomical Society meeting in June 2020. The findings are significant because the observations conflict with some previous assumptions about the large-scale structure of the universe.

Since the time of Edwin Hubble, astronomers have believed that the universe is inflating with no particular direction and that the in it are distributed with no particular cosmological structure. But Shamir’s recent observations of geometrical patterns of more than 200,000 galaxies suggest that the universe could have a defined structure and that the early universe could have been spinning. Patterns in the distribution of these galaxies suggest that spiral galaxies in different parts of the universe, separated by both space and time, are related through the directions toward which they spin, according to the study.

A shaky ride to a smooth launch

Posted by in category: space

Ordinarily, planning a mid-afternoon launch from Florida during the summer would be inadvisable, especially if there’s no margin for error. The heat and humidity can make for “dynamic” weather conditions (to use a word that came up frequently in forecasts last week) that make it difficult to predict if a launch can proceed.

However, the schedule for the Demo-2 commercial crew mission was dictated not by Mother Nature but instead by Isaac Newton. The launch was tied to the orbit of the International Space Station so that the Crew Dragon spacecraft could reach the station after launch. That required an instantaneous launch window that, in late May, happened to be in the afternoon from the Kennedy Space Center.

Still, try explaining that to the boss. “I was told that the rocket you just witnessed had to be launched within one second, or it would be impossible for it to hit its target,” President Donald Trump said last Saturday, after a successful launch that he watched in person. He had been at the Kennedy Space Center three days earlier as well, when weather conditions didn’t quite clear in time to allow the launch.

Regulating the rise of Artificial General Intelligence

Posted by in categories: governance, robotics/AI

If you are interested in artificial general intelligence (AGI), then I have a panel discussion to recommend. My friend, David Wood, has done a masterful job of selecting three panelists with deep insight into possible regulation of AGI. One of the panelists was my friend, Dan Faggella, who was eloquent and informative as usual. For this session of the London Futurists, David Wood selected two other panelists with significantly different opinions on how to properly restrain AGI.

As research around the world proceeds to improve the power, the scope, and the generality of AI systems, should developers adopt regulatory frameworks to help steer progress?
