Can augmented reality reduce "road rage?"

This week’s Question: A new "CarNote" app from the Eindhoven University of Technology in the Netherlands aims to use augmented reality to improve the driving experience and reduce "road rage." CarNote's driver-facing periscope lens and transparent display projects information from a smartphone, allowing users behind the wheel to communicate and signal intentions. For example, a driver in a rush to a hospital could notify those in nearby vehicles, potentially reducing aggressive behavior like confrontations or honking the horn. The technology even has a "like" system that allows drivers to register or rate fellow travelers on the road. What do you think? Can augmented reality reduce "road rage?"

'Tougher-than-Metal' Hydrogels Support New Biomaterials

Scientists from Japan's Hokkaido University have created tough hydrogels combined with woven fiber fabric. The "fiber-reinforced soft composite" fabrics are highly flexible, stronger than metals, and can support a number of potential applications, including artificial ligaments and tendons subjected to load-bearing tension.

Mechanical Metamaterials Can Block Symmetry of Motion

Engineers and scientists at the University of Texas at Austin and the AMOLF institute in the Netherlands have invented mechanical metamaterials that transfer motion in one direction while blocking it in the other. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side. The researchers developed the mechanical materials using metamaterials, which are synthetic materials with properties that cannot be found in nature.

Exo-Brake “Parachute” to Enable Safe Return for Small Spacecraft

Engineers at NASA’s Ames Research Center in Moffett Field, CA have been testing its Exo-Brake technology as a simple design that promises to help bring small payloads back through Earth’s atmosphere unharmed. An Exo-Brake is a tension-based, flexible braking device resembling a cross-parachute that deploys from the rear of a satellite to increase the drag. It is a de-orbit device that replaces the more complicated rocket-based systems that would normally be employed during the de-orbit phase of re-entry.

Unified Approach Improves the Accuracy of Five-Axis Machine Tools

Five-axis machine tools are computer-numerically controlled (CNC) machines that can move, cut, or mill a part on five different axes at the same time. Because of inherent geometric errors, manufacturers must make adjustments when calibrating these machines. Several different approaches exist to help compensate for the errors, but none of them provides a complete picture. Researchers at Missouri University of Science and Technology set out to find a way to eliminate that piecemeal approach and develop a new way to capture complicated geometric errors and automatically generate compensation tables.

Six-Legged Robots Move Faster with Bipod Gate

Researchers have discovered a faster and more efficient gait, never observed in nature, for six-legged robots walking on flat ground. Bio-inspired gaits, which are less efficient for robots, are used by real insects because they have adhesive pads to walk in three dimensions. (Credit: EPFL/Alain Herzog)

Researchers in Lausanne, Switzerland have determined that a bipod gait is the fastest and most efficient way for six-legged robots to move on flat ground, provided they don’t have the adhesive pads used by insects to climb walls and ceilings. This suggests designers of insect-inspired robots should make a break with the nature-inspired tripod-gait paradigm.

Will packages be effectively delivered by parachute?

This week's Question: Amazon recently filed a patent for parachute-aided delivery of packages. The proposed idea imagines drones releasing parcels from the sky, deploying parachutes to slow their descent and ensure the valuables inside remain intact. To address gusts of wind or unexpected obstacles, a drone will hover nearby, monitoring a package as it falls. If the parcel moves off course, the drone can deploy methods (like bursts of compressed air!) to correct its descent. What do you think? Will packages be effectively delivered by parachute?

Researchers Advance Printable Solar Cell Possibilities

By finding a new way to manufacture low-cost perovskite solar cells, a team at the University of Toronto believes that making solar cells could someday be as easy and inexpensive as printing a newspaper. The researchers' alternative solar technology supports the development of low-cost, printable solar panels capable of turning nearly any surface into a power generator.

Will "$100-per-killowatt-hours" batteries boost wind and solar energy efforts?

This week’s Question: The Department of Energy (DOE) has set a goal of building a battery that stores energy for less than $100 per kilowatt-hour, making stored wind and solar energy competitive with energy produced from traditional power plants. Today’s lead INSIDER story featured a new flow battery that offers the potential to significantly decrease the costs of production. "If you can get anywhere near this cost target then you change the world," said researcher Michael Aziz. "It becomes cost effective to put batteries in so many places. This research puts us one step closer to reaching that target." What do you think? Will "$100-per-killowatt-hours" batteries boost wind and solar energy efforts?

Long-Lasting Flow Battery Advances Renewable Energy Efforts

A new flow battery from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) stores energy in organic molecules dissolved in neutral pH water. Losing only one percent of its capacity per 1000 cycles, the non-toxic, non-corrosive device offers the potential to significantly decrease the costs of production.
