Lead-free hybrid material turns motion into powerful electric charge
Researchers from the University of Birmingham, Oxford, and Bristol have developed a new lead-free hybrid piezoelectric material based on bismuth iodide that efficiently converts mechanical motion into electricity. This soft, durable material matches the performance of conventional lead-based ceramics like lead zirconate titanate (PZT) but avoids the environmental and health hazards associated with lead. Unlike PZT, which requires high-temperature processing (~1000°C), the bismuth-iodide hybrid can be synthesized at room temperature, making it easier and greener to produce. This innovation holds promise for powering sensors, wearable devices, medical implants, and flexible electronics in a more sustainable way. The team used advanced characterization techniques, including single-crystal X-ray diffraction and solid-state nuclear magnetic resonance (NMR), to reveal that halogen bonding between the organic and inorganic components is key to the material’s piezoelectric properties. This bonding induces a subtle structural instability that breaks symmetry, enhancing the piezoelectric response without the drawbacks of traditional

Rice University researchers have developed a novel two-step flash Joule heating chlorination and oxidation (FJH ClO) process for recycling lithium-ion batteries that significantly reduces chemical use and energy consumption. This acid-free method rapidly extracts lithium, cobalt, and graphite from spent batteries with high purity by first exposing battery waste to chlorine gas to break down materials, then heating in air to form metal oxides that separate from lithium chloride, which dissolves easily in water. Compared to conventional recycling methods that rely on strong acids, long reaction times, and generate wastewater, the FJH ClO process uses about half the energy and up to 95% fewer chemicals, offering a cleaner, faster, and more environmentally friendly alternative. The technique enables full-spectrum recovery of critical battery materials in a streamlined, single-route process, avoiding multiple chemical treatments common in existing methods. This efficiency not only promises economic benefits through lower operating costs and faster turnaround but also helps reduce reliance on new mining, mitigating environmental impact. The research

Researchers at the University of California, Davis have developed a novel Stirling engine prototype that generates mechanical power at night by exploiting the temperature difference between the warm ground and the cold of outer space. Unlike traditional engines that require large heat gradients, this Stirling engine operates efficiently with small temperature differences. The device uses a radiative cooling panel pointed at the night sky to shed heat into space, creating a temperature gap sufficient to drive the engine’s piston and spin a flywheel without any fuel input. Testing over a year demonstrated that the system can produce at least 400 milliwatts of mechanical power per square meter, enough to power small devices such as fans or generate electrical current via an attached motor. The technology works best in dry, clear-sky environments and could be applied to ventilate greenhouses or buildings during nighttime when circulation is needed but solar power is unavailable. UC Davis has filed a provisional patent and plans to refine the design and scale up applications, highlighting space as a practical heat sink for continuous

Researchers from the University of Sydney and Dewpoint Innovations have developed a nano-engineered polymer coating that passively cools buildings and captures water from the air without requiring energy input. This porous polymer paint-like material reflects up to 97% of sunlight and radiates heat, keeping surfaces up to six degrees Celsius cooler than the surrounding air under direct sunlight. The cooler surface promotes condensation of atmospheric water vapor, enabling the collection of dew even in dry conditions. In a six-month outdoor trial on the Sydney Nanoscience Hub roof, the coating collected dew on over 32% of days, harvesting up to 390 mL of water per square meter daily under optimal conditions—sufficient for meeting the drinking water needs of one person with a 12-square-meter surface. The coating achieves high solar reflectivity through its internal porous structure, avoiding UV-absorbing pigments that limit traditional cool roof coatings and cause glare. This design balances performance with visual comfort and durability, maintaining robust functionality without degradation under harsh sunlight

Scientists at Spain’s CIC biomaGUNE, in collaboration with BCMaterials and CIC EnergiGUN, have developed artificial conductive proteins designed for energy storage and transport. These proteins are biocompatible, stable, and easy to process, making them promising candidates to replace conventional, often hazardous materials used in batteries and supercapacitors. The proteins are engineered through a modular approach, assembling small molecular units into stable structures whose functions—such as ionic conduction—can be precisely tailored by genetically modifying the DNA blueprint. This modification enables efficient electrical charge movement, allowing the proteins to be integrated into energy storage devices capable of rapid energy release and storage. The biocompatibility of these conductive proteins addresses a significant challenge in implantable medical devices, where traditional rigid metals and silicon components can cause tissue irritation and damage due to stiffness mismatch with soft body tissues. These protein-based materials offer a safer, non-toxic alternative for bioelectronic applications, including pacemakers, implantable glucose sensors, and brain electrodes for

A recent study by scientists at the University of Sharjah, published in Nuclear Engineering and Design, reveals that hydrogen production from nuclear waste can be increased up to tenfold using a novel process called radiation-enhanced electrolysis. This approach leverages the radioactivity of nuclear waste to split water molecules into hydrogen and oxygen efficiently, transforming a long-standing environmental hazard into a valuable clean energy resource. The study surveys various innovative technologies, including catalyst-enhanced electrolysis, uranium-based catalysis, methane reforming with uranium catalysts, radiolysis with additives like formic acid, and liquid-phase plasma photocatalysis, all of which improve hydrogen yield while reducing radioactive waste volume and storage needs. Despite the promising potential of these methods, the researchers highlight significant challenges, primarily the strict regulatory controls on handling radioactive materials, which limit direct experimentation with nuclear waste and often force reliance on simulated radiation sources. This regulatory barrier may affect the accuracy and practical application of research findings. Additional technical hurdles include risks of syngas contamination

British engineer and YouTuber Chris Doel created a 2.52 kWh off-grid power wall using 500 recycled lithium-ion batteries salvaged from disposable vape pens. By collecting discarded vapes, testing each battery for viability, and assembling them into 56 modules with 3D-printed holders, Doel constructed a system that delivers about 50 volts DC. This power wall, connected to an inverter, converts the energy to standard 230 volts AC, enabling him to run his workshop appliances such as a kettle, microwave, fan, and computer without relying on the electrical grid. Doel’s project not only showcases a practical reuse of electronic waste but also highlights the environmental impact of disposable vapes, which often end up in landfills despite containing rechargeable batteries. His setup, weighing around 38 kilograms and valued at approximately £2,500 if built with new batteries, was assembled using mostly reclaimed materials and repurposed components like a scooter battery management system.

Chinese researchers at Nanjing University of Aeronautics and Astronautics have developed a novel floating hydrovoltaic generator, called the water-integrated droplet electricity generator (W-DEG), that converts the kinetic energy of falling raindrops directly into electricity while floating on water surfaces. Unlike traditional droplet electricity generators that rely on rigid, land-based metal electrodes and heavy materials, the W-DEG uses natural water as both the structural substrate and conductive electrode. This design reduces material weight by about 80% and cuts costs nearly in half, while producing voltages around 250 volts per droplet—comparable to conventional devices. The water’s incompressibility and surface tension provide mechanical support for raindrop impacts, and ions in the water act as stable charge carriers. The W-DEG demonstrates strong durability and environmental resilience, maintaining stable operation under varying temperatures, salt concentrations, and biofouling conditions due to its chemically inert dielectric layer and water-based structure.

US scientists at Princeton University have developed a breakthrough method to produce green hydrogen fuel using reclaimed wastewater instead of costly ultrapure water. Traditionally, green hydrogen production via electrolysis requires ultrapure water to prevent impurities from damaging the proton exchange membrane in electrolyzers. The Princeton team discovered that calcium and magnesium ions in wastewater cause scaling and rapid performance decline in standard electrolyzers. To overcome this, they acidified the reclaimed wastewater with sulfuric acid, which provides abundant protons that outcompete these problematic ions, maintaining ion conductivity and enabling continuous hydrogen production for over 300 hours without system failure. This innovation significantly reduces both the environmental impact and cost of hydrogen production. Using reclaimed wastewater cuts water treatment costs by approximately 47% and reduces energy consumption related to water purification by about 62%. The acid used in the process is continuously recirculated, enhancing sustainability. The researchers are now collaborating with industry partners to scale up the technology and test it with pretreated seawater. Their work supports broader efforts to integrate

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a novel, low-temperature process to produce 100% pure hydrogen from ammonia using recycled silicon from discarded solar panels. This mechanochemical method employs a ball milling technique at just 50°C (122°F), significantly lower than conventional ammonia cracking processes that require temperatures between 400°C and 600°C. The process involves shaking ammonia gas and finely powdered silicon in a sealed container, where mechanical impacts activate the silicon to decompose ammonia, releasing hydrogen gas. A key innovation is the in-situ capture of nitrogen byproduct as solid silicon nitride, eliminating the need for energy-intensive hydrogen purification steps and achieving a hydrogen generation rate of 102.5 mmol per hour with perfect purity. Beyond efficiency, the technology offers strong sustainability benefits by utilizing silicon recovered from end-of-life solar panels, addressing the growing environmental challenge of photovoltaic waste projected to exceed 80 million tons by 2050.

The article explores the concept and mechanics behind energy-generating sidewalks, which capture the energy produced by human footsteps and convert it into usable electricity. This technology has been implemented in various countries and has potential applications ranging from powering city infrastructure to energizing entertainment venues like discotheques or playgrounds. The fundamental principle relies on the physics of energy conservation, illustrated through the analogy of a bouncing ball that exchanges kinetic, gravitational potential, and spring potential energy, with some energy lost as heat or sound during each impact. Humans maintain a constant height while walking by replenishing lost energy through muscular effort fueled by food, meaning the system is not closed but continuously energized internally. Energy-harvesting sidewalks capitalize on the otherwise "wasted" kinetic energy from footsteps using two main technologies: piezoelectric generators, which produce electricity when mechanical stress is applied to certain materials, and electromagnetic generators, which convert mechanical motion into electrical energy. Both methods have long-standing scientific foundations, but their novel application in pedestrian pathways presents an

The article highlights an innovative benefit of heat pump water heaters (HPWHs): they provide free, filtered cool air as a byproduct of heating water. Unlike traditional water heaters that emit pollution, HPWHs extract heat from the surrounding air to warm water, exhausting only cool air similar to an air conditioner. This process makes them highly efficient, delivering about four units of heat for every unit of energy consumed, resulting in low electricity costs (typically $100-$150 annually). The author has installed multiple HPWHs and, after initially ducting the cool air outside, recently began exhausting it indoors, effectively using the system as a free air conditioner during hot summer days. By increasing the water temperature setting from 120°F to 140°F during peak solar production hours, the HPWH runs its heat pump for several hours, producing cooling equivalent to a small window AC unit without additional electricity costs. This strategy cools the living space during the hottest part of the day, with built-in anti-scald

The hydrochloric acid byproduct can be safely neutralized and reused, potentially replacing several energy-intensive industrial production routes. A significant innovation of this method is its ability to handle polyvinyl chloride (PVC), a challenging plastic due to its chlorine content, which traditionally requires separate, high-temperature dechlorination steps to avoid toxic emissions. The new process integrates dechlorination with fuel production, converting PVC into chlorine-free fuel hydrocarbons and hydrochloric

Researchers at Kyoto University have developed an innovative recycling method called the selective extraction–evaporation–electrolysis (SEEE) process to recover rare-earth elements (REEs) from used magnets, particularly those containing neodymium (Nd) and dysprosium (Dy). These REEs are critical for high-performance magnets used in green technologies such as electric vehicles and wind turbines. The SEEE process demonstrated high efficiency, recovering 96% of neodymium and 91% of dysprosium, both with purities exceeding 90%. This method offers a more sustainable alternative to traditional mining and hydrometallurgical recycling, which are often environmentally damaging or energy-intensive. The SEEE process involves three stages: selective extraction using a molten salt mixture to isolate REEs from magnet scraps; selective evaporation to remove byproducts and concentrate the rare-earth elements; and selective electrolysis to separate and recover the metals in high-purity metallic form based on their distinct electrochemical potentials.

Envision Energy has revived the two-blade wind turbine design with its Model X prototype, demonstrating performance comparable to traditional three-blade turbines. After decades of two-blade designs being sidelined due to issues like vibration and uneven loading, Envision’s prototype has operated onshore in Inner Mongolia for over 500 days with 99.3% availability and a mean time between failures of 2,444 hours. This success is attributed to a decade of refinements including a high-speed doubly-fed induction generator, modular components, lightweight construction, and advanced control systems that effectively manage vibration and load imbalance, challenges that previously hindered two-blade turbines. Aerodynamic studies show that while adding a second blade significantly improves efficiency over a single blade, the third blade offers only marginal gains. Two-blade turbines reduce material costs and logistical challenges, such as transporting oversized blades, which can be significant bottlenecks in onshore wind projects.

Chinese scientists at Zhejiang University have developed an innovative self-cleaning glass that uses electric fields to remove dust and particles from its surface efficiently. This thin, transparent glass (0.62 mm thick) is embedded with electric-field-driven electrodes that can clean itself within seconds, erasing up to 98% of both organic and inorganic particles without the need for water, chemicals, or significant energy. The technology leverages the unexpected behavior of charged particles exposed to alternating electric fields, causing some particles to reverse direction or jump off the surface entirely, enabling effective dust removal even in dry, dusty conditions where traditional cleaning methods struggle. Beyond removing existing dust, the glass also prevents new dust from settling by deflecting charged airborne particles, a phenomenon the researchers call the "particle shielding effect," which reduces dust buildup by nearly 90%. The glass maintains high transparency, with minimal reduction in visible light and most light loss occurring in the infrared spectrum, making it suitable for applications requiring clear visibility and energy efficiency, such as

Engineers at UCLA have developed an innovative, lightweight, and scalable outdoor cooling structure that reduces radiant temperature by about 10°F without obstructing visibility. The system combines water-cooled black aluminum panels with a transparent, infrared-reflective polymer film, creating a semi-transparent canopy that actively cools the space beneath it. Field trials on campus and at the San Fernando Swap Meet demonstrated that this “cooling tent” lowered mean radiant temperature to approximately 78°F—significantly cooler than typical shaded areas and even below the ambient air temperature. Unlike traditional opaque cooling panels that block sightlines and raise safety concerns, this design maintains an open feel while effectively wicking heat away. The structure works by circulating chilled water through hydronic panels painted black to absorb stray heat, including body heat, while the polymer film reflects infrared radiation toward the sky. Participants consistently reported feeling cooler and more comfortable under the canopy compared to nearby shaded spots.

Wyoming is the site of the first utility-scale test of an innovative wind turbine developed by Airloom Energy, a local startup focused on drastically reducing the cost of wind power. Supported initially by a $225,000 NSF Small Business Innovation Research grant in 2016, Airloom aims to produce electricity at just 2.8 cents per kWh by using a radically different design that minimizes blade size and lowers transportation, maintenance, and land costs. Their turbine features blades that rotate around a low-to-the-ground oval track rather than a traditional horizontal axis atop tall towers, addressing common aesthetic objections to wind farms and enabling more flexible site placement despite lower wind speeds at reduced altitudes. Since its inception, Airloom has secured significant funding, including $750,000 from NSF in 2017, a $4 million seed round in 2023 backed by Bill Gates–affiliated Breakthrough Energy Ventures and others, plus $5 million from Wyoming’s Energy Matching Funds and a $1.25 million

Researchers at Georgia Tech have developed a novel, cost-effective method for capturing atmospheric CO₂ by leveraging extremely cold air and simple, widely available porous sorbent materials called physisorbents. Their technique utilizes the cold energy generated during liquefied natural gas (LNG) regasification—a process that typically wastes this cold—to chill ambient air to near-cryogenic temperatures (~ -78°C). This cooling removes water vapor naturally, creating ideal conditions for physisorbents like Zeolite 13X and CALF-20 to efficiently absorb CO₂ without the energy-intensive drying steps required by traditional direct air capture (DAC) systems that rely on chemical amines. The physisorbents demonstrated roughly three times higher CO₂ capture capacity at these low temperatures compared to room temperature, while also requiring less energy for CO₂ release and offering greater durability. Economic modeling indicates this approach could reduce DAC costs to around $70 per metric ton of CO₂—less than one-third of current expenses—potential

Researchers at The Hong Kong Polytechnic University have developed a novel 3D-printed aerogel material that can desalinate seawater using only sunlight, without requiring electricity. This sponge-like aerogel, made from carbon nanotubes and cellulose nanofibers, contains microscopic air pockets and uniform vertical pores about 20 micrometers wide, which efficiently facilitate water evaporation while leaving salt behind. The material’s desalination efficiency remains consistent regardless of its size, making it scalable for larger applications. In practical outdoor tests, the aerogel was placed in seawater under a curved plastic cover, where sunlight heated the material to evaporate water. The vapor condensed on the plastic lid and was collected as fresh water, producing approximately three tablespoons of drinkable water after six hours of natural sunlight. This low-energy, sustainable desalination method offers a promising solution to global water scarcity, especially as conventional desalination plants typically require significant energy input.

Chinese researchers from Shenzhen University of Technology have developed a new type of organic solar cell (OSC) that achieves a record efficiency of around 20% while using non-toxic, environmentally friendly materials. Unlike previous OSCs that relied on harmful solvents like chloroform, these cells use toluene, a safer solvent. The team enhanced the internal morphology of the solar cells by adding two isomeric chemical additives, ODBC and PDBC, which help the materials inside the cell align more precisely. This improved alignment facilitates better sunlight absorption and charge transfer, resulting in higher efficiency and greater stability suitable for mass production. The additives work by slowing the drying process, allowing the solar cell materials to crystallize in a more orderly fashion, which boosts performance and reduces energy loss over time. The researchers optimized the placement of these additives within the solar cell layers, notably in the acceptor layer, to maximize their beneficial effects. Their best configuration achieved a certified efficiency of 19.7% using the green solvent to

Researchers from Tianjin University and other Chinese institutes have developed a novel method enabling proton exchange membrane (PEM) electrolyzers to operate effectively using impure water, addressing a key limitation of current green hydrogen production technologies. Unlike alkaline electrolyzers, PEM electrolyzers produce higher purity hydrogen suitable for fuel cells but require ultrapure water, as impurities can degrade the membrane and increase costs. The new approach involves creating an acidic microenvironment at the cathode by adding Bronsted acid oxide (MoO3-x), which acts as a catalyst and locally lowers pH, enhancing electrolyzer performance and durability even with tap water. This innovation was validated through advanced microscopy techniques, showing that the PEM electrolyzer maintained stable operation for over 3,000 hours at a current density of 1.0 A/cm² using impure water, with performance comparable to conventional PEM systems relying on ultrapure water. By reducing the need for costly water pretreatment and extending system lifetime, this advancement could significantly lower the costs and complexity

By mimicking nature’s use of light, the system can rearrange or reduce stubborn molecules, potentially reducing environmental impact and lowering costs in industries such as plastics and pharmaceuticals. A key advancement of the CSU method is its double-photon strategy, where two photons simultaneously provide sufficient energy to break strong molecular bonds in aromatic hydrocarbons (arenes), compounds that are usually very stable and difficult to modify. This “super-reducing” capability enables the efficient transformation of arenes into useful chemicals without hazardous reagents or extreme conditions.

Researchers at Virginia Tech have developed an innovative atmospheric water harvesting device called the "fog guitar," which significantly improves upon traditional fog collection methods. Traditional fog nets, used for centuries, suffer from design limitations such as clogging due to small holes and inefficiency from large holes letting droplets pass through. In 2018, the team introduced the "fog harp," which replaced horizontal wires with vertical fibers to increase water collection efficiency by two to seven times. However, the fog harp faced a critical issue: under heavy fog, surface tension caused the vertical fibers to tangle and clump, reducing performance when water was most abundant. To solve this, the researchers created hybrid "fog guitar" designs that reintroduced a limited number of horizontal supports—akin to guitar frets—to prevent fiber tangling while avoiding clogging. By testing seven variations with different numbers of these "frets," they identified an optimal configuration that balances the prevention of tangling and clogging, maximizing water collection efficiency even in dense fog.
