New studies highlight the potential of self-heating plasmas for fusion energy

Most energy-producing technologies used today are unsustainable, as they cause significant damage to our planet’s natural environment. In recent years, scientists worldwide have thus been trying to devise alternative energy solutions that take advantage of abundant and natural resources.

In addition to , wind and seawater energy solutions, some physicists and engineers have been exploring the possibility of sourcing energy from nuclear reactions. This is the process through which two atomic nuclei combine to form a heavier nucleus and an energetic neutron.

Two research teams working at the Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) demonstrated new approaches to increase nuclear energy production via a laser-driven . Their findings, published in recent Nature and Nature Physics papers, open new exciting possibilities for one day using self-heating plasmas as sustainable energy sources.

Scientists combine AI and atomic-scale images in pursuit of better batteries

Today’s rechargeable batteries are a wonder, but far from perfect. Eventually, they all wear out, begetting expensive replacements and recycling.

“But what if batteries were indestructible?” asks William Chueh, an associate professor of materials science and engineering at Stanford University and senior author of a new paper detailing a first-of-its-kind analytical approach to building better batteries that could help speed that day. The study appears in the journal Nature Materials.

Chueh, lead author Haitao “Dean” Deng, Ph.D. ‘21, and collaborators at Lawrence Berkeley National Laboratory, MIT and other research institutions used artificial intelligence to analyze new kinds of atomic-scale microscopic images to understand exactly why batteries wear out. Eventually, they say, the revelations could lead to batteries that last much longer than today’s. Specifically, they looked at a particular type of lithium-ion batteries based on so-called LFP materials, which could lead to mass-market electric vehicles because it does not use chemicals with constrained supply chains.

GreenCore Partners With B&D Industries To Provide Labor For 10,000 Solar EV Charging Plazas

GreenCore EV Services has a goal of building and operating a network of over 10,000 solar EV charging plazas throughout the United States by the end of the decade. The company’s charging plazas will serve both consumer and commercial vehicles.

To help usher in this goal, GreenCore announced that it has selected B&D Industries to provide labor and prefabrication services to build out the company’s network of solar-powered EV charging plazas.

Scientists accidentally stumble on ‘holy grail’ of batteries

Lithium-sulfur batteries have three times the potential charge capacity of lithium-ion batteries, which are found in everything from smartphones to electric cars. Their inherent instability, however, have so far made them unsuitable for commercial applications, with lithium-sulfur batteries undergoing a 78 per cent change in size every charging cycle.

Overcoming this issue would not only radically improve the performance of battery-powered devices, it would also address some of the environment concerns that come with lithium-ion batteries, such as the sourcing and disposal of rare raw materials.

‘Exciton surfing’ could enable next-gen energy, computing and communications tech

A quasiparticle that forms in semiconductors can now be moved around at room temperature, a University of Michigan-led study has shown. The finding could cool down computers, enabling faster speeds and higher efficiencies, and potentially make LEDs and solar panels more efficient.

Today’s electronic devices rely on electrons to move both energy and information around, but about half of that energy is wasted as heat due to . Excitons, which escape traditional electrical losses, are one potential alternative.

“If you think of the past almost two decades, the computers have always been at two to three gigahertz—they never increase the speed. And that’s the reason. It just gets too hot,” said Parag Deotare, assistant professor of electrical engineering and science and corresponding author of the study.

Autonomous Trash-Eating Boats Clean Up Water Pollution

With marine debris a growing concern, innovators are getting creative — designing autonomous boats that act as on-the-water trash-eating machines.

The latest development comes from the Danish company RanMarine Technology. They’ve created an aquadrone called WasteShark that sucks up waste from the water much like a Roomba — consuming up to 200 liters of garbage in a single ride.
