Minesto’s Dragon 12, a fully operational and dynamic tidal energy device, is making waves in the renewable energy sector with its innovative approach. Resembling a futuristic military drone, the Dragon 12 behaves like an underwater kite, utilizing tidal flows to fly patterns faster than the currents, effectively harvesting renewable energy. Unlike traditional tidal turbines that remain stationary in the water, Minesto’s Dragon series is anchored to the sea bed and maneuvers like kites, optimizing energy extraction from tidal currents.

Similar to land-based wind energy kites that follow figure-eight patterns to outpace the wind, the Dragon underwater device employs dynamic movements to extract more energy from a given tidal current. This unique approach expands the economic feasibility of harnessing energy from slower tidal flows. Despite its substantial size, with a 12-meter wingspan and a weight of 28 tons, the Dragon 12 offers easier installation using a single boat and a sea bed tether.

Researchers from the Italian Institute of Technology have achieved a groundbreaking feat by creating the world’s first rechargeable battery entirely composed of food products, making it not only environmentally friendly but also completely edible. This remarkable development opens doors to potential applications in internal gastrointestinal diagnostic instruments, food quality monitoring, and even edible soft robotics.

The team, led by Mario Caironi, coordinator of the Printed and Molecular Electronics laboratory at the IIT Center in Milan, drew inspiration from biochemical reactions in living beings. The battery’s anode is crafted from riboflavin (vitamin B2), found in almonds, dairy products, and meats, while the cathode is made from the plant flavonoid quercetin, present in capers, citrus fruits, and leafy greens.

Swiss scientists from Empa (Swiss Federal Laboratory for Science and Technology) and the Slovak University of Technology have unveiled a groundbreaking construction material that could transform the industry with its exceptional insulation capabilities. The team has ingeniously harnessed the power of silica aerogel granules to create aerogel glass bricks, introducing a translucent and thermally insulating material that could significantly reduce lighting and HVAC (heating, ventilation, and air conditioning) energy demands without the need to increase insulation layer thickness.

Described as having the “highest insulating performance” among bricks in technical literature and the market, the aerogel glass brick offers not only insulation benefits but also improves visual comfort. The material is expected to enhance solar gains, leading to reduced heating costs, and decrease reliance on artificial lighting.
