“We’re thrilled that the Fiat 500e has officially begun its journey to reach customers in North America,” Fiat CEO and CMO at Stellantis said Wednesday.
The Fiat 500e is already the best-selling electric city car in Europe, ranking first in Germany, Italy, Spain, Belgium, and France. Since launching, the 500e has sold over 185,000 units globally. Now, the small electric car is about to take on North America.
The engineering of structural deformations in light-sensitive semiconductors can boost the efficiency of solar cells.
The quest for an efficient method to convert solar energy into electricity is crucial in the pursuit of carbon neutrality and environmental sustainability. Traditional solar cells are based on junctions between semiconductors, where a current is produced by photogenerated carriers separated by an electric field at the junction. Efforts to enhance solar-cell performance have focused on refining semiconductor properties and on perfecting devices. Concurrently, researchers are exploring alternative photovoltaic mechanisms that could work in synergy with the junction-based photovoltaic effect to boost solar-cell efficiency. Within this context, the engineering of a strain gradient in the material has emerged as a promising research direction. In this phenomenon, known as the flexophotovoltaic effect, an inhomogeneous strain in the material produces a photovoltaic effect in the absence of a junction [1].
The Seva Sustainable Sanitation innovation is a smart, electro-chemical toilet unit, which is suitable for use in off-grid rural areas of developing countries. It can turn toilet wastewater into disinfected water, using the power from its mounted solar panels to sterilise and clarify it. Macronutrients such as carbon, nitrogen, and phosphorus can be nearly fully recovered from the waste, leaving nothing but water that is recycled for flushing or irrigation. The toilet unit is also equipped with sensors, a mobile phone-based maintenance guide, and smart grid technology that empowers anyone in the community to repair the system when necessary. When a toilet is out of order, the technology automatically directs users to other nearby sanitation systems. So far, the solution has been deployed in four countries.

Recycling nutrients is essential for closing nutrient loops within a circular economy. Using locally available resources such as human excreta to produce bio-based recycling fertilizers can substitute mineral fertilizers and thereby promote environmentally friendly food production. To better understand the fertilizer potential and nitrogen value of human excreta, three novel and safe recycling products were evaluated in a field experiment. Two nitrified urine fertilizers (NUFs) and one fecal compost were applied alone or in combination, and compared against the commercial organic fertilizer vinasse. In addition, the uptake of pharmaceuticals was assessed for treatments with compost application. White cabbage (Brassica oleracea var. capitata f. alba) was cultivated in plots in three different soil types (sand, loam or silt) treated with the fertilizers according to plant needs and mineral soil nitrogen content. The two NUFs resulted in marketable yields similar to those of vinasse in all soil types. Combining fecal compost with a NUF led to increased marketable yield compared to compost alone. The highest yield was recorded from the sandy soil, where vinasse and NUF treatments led to comparable yields, as expected in organic productions systems (up to 72 t ha−1). The cabbage yield and total aboveground fresh biomass followed the following trend in all soils: NUFs ∼ vinasse ≥ compost + NUF ≥ compost. Nitrogen uptake in the cabbage heads and total biomass was significantly higher in sand (69.5–144 kg ha−1) than loam (71.4–95.8 kg ha−1). All compost treatments alleviated the effect of soil type and resulted in comparable nitrogen uptake and yield in all soil types. Plant uptake of pharmaceuticals (Carbamazepin) was higher in sand than in loam, and concentration in the edible part was lower than in the outer leaves. In conclusion, NUF alone appears to be a promising successful fertilizer substitute in horticultural food production. The combined application of NUF and compost led to slightly lower crop yields, but may increase soil carbon content in the long term, promoting climate-friendly food production.
In view of a growing world population and the human alteration of nutrient cycles, including nitrogen (N) and phosphorus ℗ (Rockström et al., 2009), transforming food production is a major challenge of this century (Springmann et al., 2018). Both N and P are essential nutrients for healthy plant growth in crop production; however, their addition to synthetic fertilizers is currently organized in a linear economy. The Haber-Bosch process, used to generate plant-available N from its airborne unreactive form, is energy intensive, depending on fossil fuels such as natural gas, and associated with high greenhouse gas emissions (Wang et al., 2021). P is obtained from finite, depleting phosphate rock resources and its mining is increasingly more expensive and polluting (Desmidt et al., 2015). This background emphasize the need for significant improvements of nutrient management in agriculture and for alternative, circular N and P sources to achieve global food security (Gerten et al.
A team of MIT researchers has figured out a way to create a supercapacitor simply by mixing cement, the binding ingredient of concrete, and a fine charcoal product called carbon black together with water.
Better yet, this mixture could allow a home to store a full day’s worth of energy in its foundation, potentially paving the way to an efficient renewable energy storage solution that doesn’t rely on mining rare Earth metals.
Roads made up of the material could even power electric cars wirelessly, the researchers say, or windmills could store their generated energy in their base.
A Kenyan company is proving the saying: “one person’s waste is another person’s treasure,” still rings true.
On a February morning, a group of women on a Mombasa beach pick up plastic waste that will serve to build freezers.
The waste is sold to company Kuza Freezer where employees first break it down into pellets before moulding it into cold storage units.
How can water-based batteries help improve lithium-ion energy storage and technology? This is what a series of studies published in Advanced Materials, Small Structures, Energy Storage Materials, and Energy & Environmental Science hopes to address as a team of international researchers led by Liaoning University in China have developed recyclable, aqueous-based batteries that won’t succumb to combustion or explosion. This study holds the potential to help researchers develop safer and more efficient water-based energy storage technologies for a cleaner future.
While lithium-ion batteries have proven reliable, they pose safety risks due to the organic electrolytes responsible for creating the electrical charge, which can lead to them catching fire or exploding, limiting their development for large-scale usage. To solve this problem, the researchers used water for driving the electric current between the battery’s terminals, nearly eliminating the chance for a safety hazard.
“Addressing end-of-life disposal challenges that consumers, industry and governments globally face with current energy storage technology, our batteries can be safely disassembled, and the materials can be reused or recycled,” said Dr. Tianyi Ma, who is a team member and a professor in the STEM | School of Science at RMIT University. “We use materials such as magnesium and zinc that are abundant in nature, inexpensive and less toxic than alternatives used in other kinds of batteries, which helps to lower manufacturing costs and reduces risks to human health and the environment.”
Norway boasts the highest electric vehicle adoption rate in the world. Some 82% of new car sales were EVs in Norway in 2023, according to the Norwegian Road Federation (OFV). In comparison, 7.6% of new car sales were electric in the U.S. last year, according to Kelley Blue Book estimates. In the world’s largest auto market, China, 24% of new car sales were EVs in 2023, according to the China Passenger Car Association.
“Our goal is that all new cars by 2025 will be zero-emission vehicles,” said Ragnhild Syrstad, the state secretary of the Norwegian Ministry of Climate and Environment, “We think we’re going to reach that goal.”
The Norwegian government started incentivizing the purchase of EVs back in the 1990s with free parking, the use of bus lanes, no tolls and most importantly, no taxes on zero-emission vehicles. But it wasn’t until Tesla and other EV models became available about 10 years ago that sales started to take off, Syrstad said.
