The new battery could increase the lifetime of electric vehicles by 10 to 15. The lithium battery is made up of multiple levels to protect the inner electrodes. (Photo from Second Bay Studios/Harvard SEAS)   The electric vehicle market is on the rise. We’re starting to see more electric cars on the road, but if the market wants to continue expanding, the cars need better battery power. Currently, lithium-ion batteries are too heavy, too expensive, and take too long to charge. A team ...
You never notice when something is implemented correctly because it 'just works' , but when it's done wrong, wow you really do notice.   USB is one of those technologies that hardware designers manage to repeatedly get wrong, even the Raspberry Pi Trading has managed to leave out a resistor or capacitor for the USB-C standard power on the latest Raspberry Pi, which I believe has now been fixed, but it's typical as well to not know what kind of USB-C cable you're getting.   Benson Leu ...
CUT’s concept involves adding short carbon fibers into a cement-based mixture, making it more conductive. Then, they integrated a metal-coated carbon-fiber mesh. (Image Credit: Yen Strandqvist/Chalmers University of Technology)   One day, the concrete in large buildings could collect renewable energy. Researchers at the Chalmers University of Technology (CUT) unveiled a new concept for cement-based rechargeable batteries that potentially forms an entire building, storing energy from ...
Dr. Raghav Sharma holds a chip integrated with 50 spin-torque oscillators. The new technology converts Wi-Fi signals into energy, which can power small devices. (Image Credit: National University of Singapore)   Researchers from the National University of Singapore and Japan's Tohoku University developed a new technology that utilizes spin-torque oscillators (STOs) to collect and convert Wi-Fi signals into energy, powering small electronics. During their demonstration, the team managed to ...
New York City’s Empire State building underwent some upgrades over the past decade, making it more energy-efficient. (Image Credit: Jonathon Roger/Unsplash)   The  Empire State building’s chiller plant consists of a series of pipes, gauges, and steel valve wheels that have gone through some upgrades throughout the years. These were taken apart and reassembled using their original materials as part of an extensive retrofit that began ten years ago and continues today. This ...
Renewables and EV minerals need a sharp supply increase to meet climate change goals. The IEA warns that critical minerals need a sharp increase in supply to meet the planet’s climate goals. (Image Credit: Alex Eckermann/Unsplash) The International Energy Agency says that to reach Earth’s climate goals, nickel, cobalt, lithium, copper, and rare earth elements supplies for wind turbine and electric vehicle technologies need to increase over the following decades. Demand outlooks and ...
Researchers have come up with a method to convert food waste into jet fuel. (Image Credit: Tango Tsuttie/Unsplash)   Researchers from the National Renewable Energy Laboratory (NREL), the University of Dayton, Yale University, and Oak Ridge National Laboratory have created a method that converts food waste into sustainable aviation fuel (SAF). The process involves transforming volatile fatty acids (VAF) from fermenting food waste into paraffin molecules, which can be used in jet fuel. Their ...
