Electrified road to wirelessly charge EVs in Michigan

Posted by in categories: business, economics, employment, energy, sustainability, transportation

Michigan will become the first state in America to deploy inductive vehicle charging technology in roads, in an effort to accelerate the adoption of electric vehicles (EVs).

Governor of Michigan, Gretchen Whitmer, made the announcement during the opening ceremony of the Motor Bella auto show on Tuesday. The Inductive Vehicle Charging Pilot is a partnership between Michigan’s Department of Transportation (MDOT) and the Office of Future Mobility and Electrification (OFME). It will deploy an electrified roadway system allowing electric cars, buses, shuttles and other vehicles to charge while driving, allowing them to operate continuously without stopping to charge. This will address range anxiety, while turning public roads into safe, sustainable, shared energy platforms.

“Michigan was home to the first mile of paved road, and now we’re paving the way for the roads of tomorrow with innovative infrastructure that will support the economy and the environment, helping us achieve our goal of carbon neutrality by 2050,” said Governor Whitmer. “This project reinforces my commitment to accelerating the deployment of electric vehicle infrastructure in Michigan and will create new opportunities for businesses and high-tech jobs amidst the transition to electric vehicles.”

New Solid-State Battery Surprises Researchers Who Created It

Posted by in categories: chemistry, energy, engineering

The study had been supported by LG Energy Solution’s open innovation, a program that actively supports battery-related research. LGES has been working with researchers around the world to foster related techniques.

Silicon anodes are famous for their energy density, which is 10 times greater than the graphite anodes most often used in today’s commercial lithium ion batteries. On the other hand, silicon anodes are infamous for how they expand and contract as the battery charges and discharges, and for how they degrade with liquid electrolytes. These challenges have kept all-silicon anodes out of commercial lithium ion batteries despite the tantalizing energy density. The new work published in Science provides a promising path forward for all-silicon-anodes, thanks to the right electrolyte.

New Research Could Usher in a New Age of Solid-State Batteries

Posted by in categories: energy, futurism

LG Energy Solutions, a partner in the research, has plans for mass production of solid-state batteries by 2027.

While the transition to renewable energies is a high priority, there is also a need to develop energy storage equipment to tide over low production cycles. Lithium-ion batteries are currently our best bet but can’t serve very high energy requirements. Researchers at the University of California, San Diego, in collaboration with LG Energy Solutions, may have solved our requirement of energy-dense batteries by developing a solid-state battery with a silicon anode.

Lithium-ion batteries use graphite coated in copper foil, as their anodes or negative electrode. While this system does work well, future applications such as electric-powered flight and energy storage for grids require batteries with high energy densities. Scientists around the globe are working to resolve this issue and ubiquitous silicon is a potential answer.

Strange Electron Behavior Surprises Solid State Physicists

Posted by in categories: energy, physics, transportation

A surprise result for solid state physicists hints at an unusual electron behavior.

While studying the behavior of electrons in iron-based superconducting materials, researchers at the University of Tokyo observed a strange signal relating to the way electrons are arranged. The signal implies a new arrangement of electrons the researchers call a nematicity wave, and they hope to collaborate with theoretical physicists to better understand it. The nematicity wave could help researchers understand the way electrons interact with each other in superconductors.

A long-standing dream of solid state physicists is to fully understand the phenomenon of superconductivity — essentially electronic conduction without the resistance that creates heat and drains power. It would usher in a whole new world of incredibly efficient or powerful devices and is already being used on Japan’s experimental magnetic levitation bullet train. But there is much to explore in this complex topic, and it often surprises researchers with unexpected results and observations.

This EV Charger Doesn’t Need a Grid Connection or Digging to Install

Posted by in categories: energy, transportation

Working with electric utilities is one of the more time consuming parts of building new charging stations, as quite a lot of infrastructure work and planning goes into building an EV station, as the local grid has to be taken into account in such projects.

But what if electric utilities weren’t involved at all, and a station could just be delivered on a flatbed truck with a forklift?

That’s the promise of a fast-charging station dubbed Drive Booster, developed by E.ON and Volkswagen that was just opened for use in Essen, Germany. The concept behind it is quite simple: Instead of drawing power directly from the grid, the charger has its own integrated battery, and draws power from a normal power connection found in any supermarket, like a soda machine or other large appliance. The charger can juice up two EVs at once at speeds of up to 150 kW, giving them enough range in 15 minutes to travel 124 miles.

Glow-in-the-dark plants could act as passive lighting for public spaces

Posted by in categories: cyborgs, energy, health, nanotechnology, transhumanism

A decent chunk of energy usage goes towards lighting, so scientists at MIT are developing a new kind of passive lighting – glow-in-the-dark plants. In the latest experiment, the team has made them glow much brighter than the first generation plants, without harming their health.

The emerging field of “plant nanobionics” involves embedding nanoparticles into plants to give them new abilities. Past work by the MIT team has created plants that can send electrical signals when they need water, spinach that could be used to detect explosives, and watercress that glows in the dark.

As interesting as that last one was, the glow wasn’t particularly bright – about on par with those plastic glowing stars many of us stuck to our ceilings as kids. That’s a cool novelty but not much help for the ultimate use case of passive lighting.

Sunlight and salt water join forces in electricity-free cooling system

Posted by in category: energy

There are many parts of the world which lack infrastructure, but that get a lot of sunlight … which makes buildings uncomfortably hot. A new system could help, as it uses a combination of sunlight and salt water – but no electricity – to produce a cooling effect.

Currently being developed at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), the experimental setup takes advantage of a natural “phase-change” phenomenon in which energy is absorbed as salt crystals dissolve within water. This means that if salt is added to warm water, that water rapidly cools as the salt dissolves.

After some experimentation with different types of salt, it was found that one known as ammonium nitrate worked best. Mainly because it’s highly water-soluble, its cooling power is four times greater than that of the next-best salt, ammonium chloride. As an added bonus, ammonium nitrate is already widely utilized in fertilizer, and is quite inexpensive.

Game-changer for clean hydrogen production

Posted by in categories: energy, sustainability

Curtin University research has identified a new, cheaper and more efficient electrocatalyst to make green hydrogen from water that could one day open new avenues for large-scale clean energy production.

Typically, scientists have been using , such as platinum, to accelerate the reaction to break water into hydrogen and oxygen. Now Curtin research has found that adding nickel and cobalt to cheaper, previously ineffective catalysts enhances their performance, which lowers the required to split the water and increases the yield of hydrogen.

Lead researcher Dr. Guohua Jia, from Curtin’s School of Molecular and Life Sciences, said this discovery could have far-reaching implications for sustainable green fuel generation in the future.
