Tropical Storm Hilary: Amateur Radio Activates

Amateur Radio operators activated on Sunday, August 20, 2023 to provide communications and information for Tropical Storm Hilary. As of mid-morning Sunday, the system was moving up the Baja Peninsula of Mexico, expected to cross into Southern California. Heavy rains were falling in San Diego, and local media reported that 250 airline flights had been cancelled.

Amateur radio operations began Sunday morning. The WX4NHC amateur radio station at the National Hurricane Center was on air.

Arecibo Observatory Officially Shuts Down

/

The Arecibo Observatory, which recently suffered catastrophic damage to its 305-meter telescope, has officially shut down all research efforts.

Since the collapse of the main telescope in 2020, the US National Science Foundation (NSF) had intended to convert the facility into an educational research center, but doubts have risen whether that plan will pan out.

After weathering hurricanes, earthquakes, budget cuts and a pandemic-induced shutdown, the iconic Arecibo Observatory in Puerto Rico is closing its doors on 14 August. After its main instrument collapsed two years ago, the site was supposed to shift from carrying out astronomy and other research to being a science education centre. But concrete plans for that have yet to materialize — and funding for current operations has run out.

Liquid Metal Battery to Flow into the Commercial Market

/

The unending search for better battery power with improved storage capacity has led to yet another innovative design - and this one is about to be released for commercial use.

A professor emeritus from the Massachusetts Institute of Technology has created a liquid metal battery that he will soon be introducing into the commercial market as a low-cost, long-life option.

Donald Sadoway is a materials scientist who has focused on developing affordable batteries throughout his years of research He cofounded his company, Ambri, in 2010, as a way to commercialize his liquid metal battery, which contains molten metal electrodes and a molten salt electrolyte. The Massachusetts-based company will be working with Colorado-based Xcel Energy in early 2024. Ambri plans to install a 300-kWh system for the utility and expects it to be up and running late next year.

“The concept of a liquid-metal battery makes it unique for stationary storage. It’s not flammable, unlike lithium. And it’s resistant to capacity fade. We’ve got data on thousands of charge cycles, which is years of operation. This thing should go 20 years and still retain 95 percent of its capacity.”
— Donald Sadoway

An article on the IEEE Spectrum website said that the liquid-metal battery could lead to a substantial reduction in energy costs.

The scientist credits the battery's alternative components for creating a system design different from that found in lithium-ion batteries.
