There are now a number of systems in which "good" drones are used to disable "enemy" drones, such as those conducting spying missions. A new system takes a safer approach to the task, in that the captured drones don't simply plummet to the ground.Continue ReadingCategory: Drones, TechnologyTags: Drone security
Although 3D printing technology continues to improve, it's still limited by relatively long print times and low resolution. A new technology could help, by simultaneously utilizing multiple small print nozzles instead of a single big one.Continue ReadingCategory: 3D Printing, TechnologyTags: Rutgers University, Manufacturing
While greenhouses produce wastewater that may contain pollutants, microalgae-growing operations require a source of water – which is scarce in many regions. A new project aims to address both problems, by growing water-purifying algae in readily available greenhouse runoff.Continue ReadingCategory: Good Thinking, LifestyleTags: Algae, Agriculture, Greenhouse, Water Conservation
The boss of WhatsApp says it will not “lower the security” of its messenger service. If asked by the government to weaken encryption, it would be “very foolish” to accept, […] The post Tech Digest daily roundup: WhatsApp says it will not ‘lower security’ appeared first on ShinyShiny.
Although it's always best to reuse and recycle, many small, simple, low-power electronic devices tend to be single-use. A new paper battery could make them more eco-friendly, as it's activated by water, and it biodegrades once discarded.Continue ReadingCategory: Electronics, ScienceTags: Empa, Batteries, Environmentally-friendly, Biodegradable, Paper
While we've seen a number of robotic grippers inspired by various animals, US scientists have now taken a much more "direct" approach. They've devised a method of using actual dead spiders to delicately grasp small objects.Continue ReadingCategory: Robotics, TechnologyTags: Rice University, Spiders, Biomimicry
Looking to recapture some of the glory of its V-16 flagships from nearly a century ago, Cadillac is previewing its envelope-pushing Celestiq. A stretched ultra-luxury sedan for modern day, the Celestiq combines regal proportions with an all-electric powertrain, multi-zone smart glass roof and all-seat digital infotainment system. We've read this manuscript before with the likes of the 2004 Sixtee
Bay Area startup Earthgrid says it's developing a plasma boring robot that can dig underground tunnels 100x faster and up to 98% cheaper than existing tech, and it plans to use it to start re-wiring America's energy, internet and utilities grids.Continue ReadingCategory: Energy, ScienceTags: Tunnel, Infrastructure
Last November we first heard about the radical Supre Drive mountain bike drivetrain, invented by Canadian mechanical engineer Cedric Eveleigh. Now, just eight months later, it's found its way onto Nicolai Bicycles' commercially available Nucleon 16 high-pivot enduro bike.Continue ReadingCategory: Bicycles, TransportTags: Mountain Bikes, Cycling
Everyone knows that the application of heat is necessary to boil water, but thanks to new research, much less heat may soon be required. A novel surface treatment allows water to reach a boiling point more easily, thus requiring less energy to do so.Continue ReadingCategory: ScienceTags: MIT, Water, Steam Power, Energy-saving is a social bookmarking place where you can share, find & discuss the best news around on most topics.
