Scientists at Australia’s RMIT have developed a tiny sponge with big potential, and say the micron-sized material can be used to convert discarded cooking oil into biodiesel in a very cost-effective manner. And the catalyst is no one-trick pony, with the ability to also turn other waste products into valuable building blocks for a range of materials.
Seattle-based Ultra Safe Nuclear Technologies (USNC-Tech) has developed a concept for a new Nuclear Thermal Propulsion (NTP) engine and delivered it to NASA. Claimed to be safer and more reliable than previous NTP designs and with far greater efficiency than a chemical rocket, the concept could help realize the goal of using nuclear propulsion to revolutionize deep space travel, reducing Earth-Mars travel time to just three months
If you’ve ever wanted to spend a night inside a dumpster – but without the accompanying smell – then Culture Campsite may be of interest. Situated on a former parking lot in Rotterdam, the Netherlands, it features an eclectic mix of micro-shelters made from recycled materials and objects including farm equipment, feed silos, and more.
People’s concept of the flying car has shifted over the last five years or so as electric VTOL designs have started to receive a ton of money and attention. But some remain unconvinced, and Greg Brown is vehemently among them. eVTOLs, Brown reckons, will be little more than short-range, low-speed helicopter replacements in the near future.
Walking, legged robots may excel at climbing over obstacles, but wheels are still more efficient for travelling over smooth ground. That’s why engineers at ETH Zurich have added powered wheels to their existing ANYmal quadruped robot.
Using tiny robots to deliver drugs is promising pathway when it comes to limiting side effects and increasing effectiveness, and some take a more theatrical approach than others. Scientists at Purdue University have come to the party with a back-flipping microbot that can tumble its way through the colon to release its payload when desired, all while being controlled externally by a magnetic field.
There’s really nobody in the ebike world I can think of that makes bikes like Nireeka. These guys aren’t interested in stealth, or retro, or making bikes that look like anyone else’s. They work exclusively with their own carbon-fiber frames, which feature strangely flowing sci-fi designs with twisting edges and curves and angles in a style of their very own.
AeroVironment has unveiled its latest loitering missile unmanned aircraft system for the US Army and other customers. Based on the Switchblade 300, which was deployed with US forces in Iraq and Afghanistan in 2011, the Switchblade 600 is larger with increased capabilities.
