State plans for the National EV Charging Infrastructure (NEVI) Formula Program were due to the Joint Office of Energy and Transportation this week, and many states released a draft plan for feedback in the last couple of months. The NEVI Program is one of two programs in the Bipartisan Infrastructure Law that provide funding for publicly-accessible electric vehicle (EV) charging infrastructure. Program funds can be used to plan for, install, operate, and maintain EV charging stations along travel corridors, with a focus on designated Alternative Fuel Corridors. Funding under the NEVI program totals $5 billion from 2022 through 2026. Funds will be allocated to states each year for implementation based on a pre-established formula, provided the departments of transportation in those states submit a satisfactory EV charging plan to the Joint Office, with updates to the plan required annually.
So what’s in the draft plans?
I pulled a few draft plans to look at as a starting point, aiming for a cross section of states in different regions, with different politics, with different economic stakes in the EV transition, at different places in EV adoption, with different weather. I couldn’t get quite the representative cross section I wanted because there are still big gaps in which states have released a draft plan. I decided to start with Alabama, California, Texas, and Wyoming.
The concrete industry is just one of many looking at new manufacturing methods to reduce its carbon footprint. These efforts are essential to fulfilling the Paris Agreement, which asks each of its signees to achieve a net-zero carbon economy by 2050. However, a new study from researchers in Japan and Belgium and focusing exclusively on Japan concludes that improved manufacturing technologies will only get the industry within 80% of its goal. Using a dynamic material flows analysis model, the study claim that the other 20% will have to come from changes in how concrete is consumed and managed, putting expectations on the buyer as well as the seller.
Electric cars, fluorescent lights, water-saving shower heads, these are all examples of efforts to lower our carbon footprint. However, the energy savings are made from the supply side, with companies developing new technologies that reduce the amount of energy consumed for the same amount of use. Notably, they put little demand on the user, who can use the product no differently than before.
The same holds true for concrete, the most consumed human-made material in the world. Many studies have shown the potential for making the concrete industry more energy efficient through esoteric efforts like “clinker-to-cement ratio reduction,” “cement substitution with alternative binders,” and “carbon capture and utilization.” The problem, explains Dr. Takuma Watari, a researcher at the Japan National Institute for Environmental Studies and lead of the new study, is that supply-side efforts are not enough if nations are serious about achieving net-zero carbon emissions.
T he introduction of lithium-ion (Li-ion) batteries has revolutionised transport technology. We wouldn’t be witnessing the current electric vehicle (EV) revolution without them. However, with the production of these batteries, which contain lithium and cobalt, comes associated with environmental and social costs. In the Democratic Republic of Congo, which accounts for 60% of the world’s supply of cobalt, a large number of unregulated mines use children as miners.
Children as young as 7 “breathe in cobalt-laden dust that can cause fatal lung ailments while working tunnels that are liable to collapse,” notes this report in The Guardian. Meanwhile, lithium mining has resulted in significant loss of groundwater in South America, while toxic leaks resulting from the process have poisoned water bodies in Tibet.
To lessen the burden on the environment, while meeting the growing demand for EVs, one possible solution could be recycling these Li-ion batteries.
Researchers at the University of Massachusetts Amherst and the Georgia Institute of Technology have 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials, which could lead to higher-performance components for applications in aerospace, medicine, energy and transportation.
The work, led by Wen Chen, assistant professor of mechanical and industrial engineering at UMass, and Ting Zhu, professor of mechanical engineering at Georgia Tech, is published by the journal Nature (“Strong yet ductile nanolamellar high-entropy alloys by additive manufacturing”).

Leadership in Indianapolis has taken strides toward lifting parking minimums, and making their city less car dependent and more transit friendly—all while keeping their fiscal house in order.
TuSimple, a transportation company focusing on driverless tech for trucks, recently transported a load of products with its autonomous truck systems.
The road to fully autonomous trucks is a long and winding one, but it’s not an impossible one, and it seems to be in closer reach than fully self-driving cars.
The company in charge of the feat was TuSimple, a transportation company focusing on driverless tech for trucks. Eighty percent of the journey, or 950 miles (1,528 km), was driven by the autonomous system, with a human at the wheel for the other 20 percent of the cross-country trip, and at-the-ready to take over the wheel if anything faulted with the technology.
Teams of mobile robots could be highly effective in helping humans to complete straining manual tasks, such as manufacturing processes or the transportation of heavy objects. In recent years, some of these robots have already been tested and introduced in real-world settings, attaining very promising results.
Researchers at Northwestern University’s Center for Robotics and Biosystems have recently developed new collaborative mobile robots, dubbed Omnid Mocobots. These robots, introduced in a paper pre-published on arXiv, are designed to cooperate with each other and with humans to safely pick up, handle, and transport delicate and flexible payloads.
“The Center for Robotics and Biosystems has a long history building robots that collaborate physically with humans,” Matthew Elwin, one of the researchers who carried out the study, told TechXplore. “In fact, the term ‘cobots’ was coined here. The inspiration for the current work was manufacturing, warehouse, and construction tasks involving manipulating large, articulated, or flexible objects, where it is helpful to have several robots supporting the object.”
