Govee launches solar-powered outdoor lights with 281 trillion color options

Govee has introduced its first solar-powered outdoor string lights: a 34-foot setup with eight color-changing bulbs, a 6W solar panel and a 4,800mAh battery that recharges in a full sunny day (USB-C backup). The lights offer 281 trillion color options, 100 preset scenes, and music-reactive modes via the mobile app, plus battery monitoring and on/off scheduling to maximize life. On a full charge they run up to 13 hours at 10 lumens; higher brightness (up to 50 lumens) reduces runtime. The IP67-rated lights and panel can endure rain or snow, and the bundle sells for $99.99 at Govee’s store and on Amazon.

Harnessing Light: A Revolutionary Approach to Water Evaporation Without Heat

Researchers at MIT have discovered that under certain conditions, light can directly cause water to evaporate without the need for heat, and it does so even more efficiently than heat. This surprising finding could have implications for various applications, including desalination, fog and cloud formation, and industrial processes. The researchers suggest that this phenomenon, which they call the photomolecular effect, could potentially lead to more efficient solar-powered desalination systems and cheap desalination methods. They are also exploring its potential use in evaporative cooling processes and its effects on climate change modeling.

"Shape-Shifting Origami Robots Take Flight with Solar Power"

Scientists at the University of Washington have developed flying robots that change shape in mid-air, using an origami-inspired design and solar power. These miniature robots can stabilize their descent by snapping into a folded position during flight. Equipped with sensors, they can collect data on temperature, humidity, and air quality. The robots are controlled remotely and researchers are working on perfecting their ability to transition back to the folded position for precise landings. The project is funded by grants from the National Science Foundation, NASA, and the Google fellowship program.

New Wearable Measures Blood Flow in Ear

Stat Health has developed a tiny wearable called Stat that fits in the upper ear and uses an infrared optical sensor to measure blood flow, helping wearers understand bouts of dizziness, fainting, headaches, and fatigue that occur right after standing up. The device is designed to help people with illnesses including Long COVID, Postural Orthostatic Tachycardia Syndrome (POTS), Myalgic Encephalomyelitis (ME), and other syndromes that are affected simply by the act of standing up. The Stat in-ear wearable is powered by a solar panel, which means in some circumstances, it’ll never need to be removed and recharged at all. The device is expected to launch in the first quarter of 2024 and will be subscription-based.
