New Technology developed, although one member of the royal family won't be able to use it. Sweat Powered Devices please log in to view this image A new wearable device generates energy from the sweat droplets on your fingertips, and it could one day replace batteries in items like Fitbits. A team of researchers from UC San Diego has developed a plaster-like strip to be worn on the finger, which can produce electricity whenever it is pressed and also convert it from excreted sweat. Even when the wearer is asleep, they can produce small amounts of electricity — a more reliable technology than other renewable energy sources like solar or wind, which are currently weather-dependent. The team is headed up by Joseph Wang, who first made a breakthrough in wearable energy devices eight years ago with a rechargeable battery powered by a temporary tattoo. Since then, Wang has helped to develop stretchable biofuel cells, which can withstand stretching, indentation, and twisting while worn on the skin. Sweat-based energy capture has also been paired with textiles. The team at UC San Diego created a T-shirt last year with biofuel cells in the chest, which convert sweat into electricity as the wearer walks or runs. But the finger strip is a significant jump forward, as it harnesses the sweatiest part of the body — the fingertips have the highest concentration of sweat glands — with minimal effort. Whereas previous wearables required a heavy workout, just 10 hours of sleep while wearing the finger strip was sufficient to produce 400 millijoules — enough energy to fuel a battery-powered watch for 24 hours. This development could be transformative for the future of wearable devices, which are currently hampered by battery size. Power capability is linked to battery volume, meaning that the more sophisticated the tech, the bulkier the item becomes. Transitioning to sweat-based charging could make devices like heart rate monitors, hearing aids, and augmented-reality contact lenses less cumbersome to wear as more power-hungry features emerge.
Most of the water in the universe is either vapour or ice. There's lots of it though, pretty much everywhere https://roboticsandautomationnews.c...-in-space-than-they-ever-knew-possible/39771/
Scientists reckon under the ice there is twice as much water on Europa than all of Earths oceans combined.
Seen a few vids like that where animals asked for human help, two memorable ones were a bear who needed helpd saving two cubs and a heard of elephants that had a baby stuck in a mud pool but couldn't get near it because they were too heavy.
