Hydrogel Coating Improves the Efficiency of Solar Panel Power Output

Electrical & Electronics, Engineering / Eduardo Paulo

A research team at The Hong Kong Polytechnic University (PolyU) has created a low-cost, easy-to-apply hydrogel coating that improves heat dissipation in solar panels by effectively cooling “hot spots,” while also boosting power generation efficiency and contributing to Hong Kong’s urban carbon-neutrality goals. Hot spots, often caused by partial shading, significantly reduce solar panel efficiency […]

AI-Driven Robots May Change the Way Tomatoes Are Harvested

Robotics, Tech / Jorge Paka

Labor shortages in the agricultural sector are fueling increased interest in robotic solutions for automated harvesting. However, certain crops continue to pose significant challenges for machines. Tomatoes, for instance, grow in clusters, requiring robots to selectively pick only the ripe fruit while leaving unripe ones on the vine. Achieving this consistently demands both accurate decision-making

Safran Sees Hydrogen Aircraft as a 22nd-Century Technology

Electrical Vehicles, Tech, Transportation & Automation / Jorge Paka

The head of French engine manufacturer Safran stated on Wednesday that hydrogen-powered airplanes, promoted by some as a means to significantly reduce carbon emissions from aviation, are not expected to become a practical technology in the near future. Olivier Andries told a French parliamentary committee that “hydrogen in aviation is more suited for the 22nd
