Research continues worldwide to develop batteries capable of competing with gasoline and diesel fuel tanks in terms of energy storage density The latest study in this direction is proposed by City University of Hong Kong, a long-lasting battery without acid. The prototype battery uses an aqueous solution free of acid and lithium ions, improving both performance and environmental friendliness. The new system uses an electrolyte based on magnesium and calcium salts, with an organic polymer acting as the anode and a substance similar to Prussian blue as the cathode. Initial…

A blend of Italian design and Japanese technology, the high-wheel scooters Honda Sh models “Sh125i” and “Sh150i” are today’s symbols of a vehicle born over 40 years ago as a “fifty,” which has dominated—and still dominates—the European market in its segment With updated styling and improved comfort, the “Sh” gained greater efficiency, positioning itself as an alternative to traditional low-wheel scooters, which were less stable and safe on uneven surfaces. In 2001, 25 years ago, a further evolution came with the replacement of two-stroke engines by two four-stroke units of…
