 | World first: Thin film absorbs 99% of electromagnetic waves
A research team in South Korea has developed the world's first ultra-thin film composite material capable of absorbing over 99% of electromagnetic waves from various frequency bands (such as 5G/6G, WiFi, and autonomous driving radar) using a single material. Conventional electromagnetic shielding materials reflect over 90% of the waves, with an actual absorbance often as low as 10%.

| | Videos+: Technologies and inspiration in action | How suction sails work on huge ships
bound4blue is a company based in Spain making waves in the shipping industry with its innovative eSAIL suction sails, which produce six to seven times more lift than a conventional sail but are rigid towers. Looking like giant cylinders, bound4blue says its technology, which ranges in height from 12 m to 36 m, works "by utilizing a fan system to drag air across the sail's aerodynamically optimized surface, generating propulsive efficiency." The company says in some applications on large ships, a pair of autonomously controlled eSAILs can cut fuel consumption and carbon emissions by 15%. Several cargo and tanker ships are testing the technology in installations of one to four units. [Credit: Image courtesy of bound4blue]
