The 10-kilowatt High Energy Laser Weapon Systems (HELWS) are to be mounted on small ground vehicles and aimed using an interface similar to a video game controller. The prototype laser weapons are from Raytheon and use commercial electronic components like high-performance lithium-ion batteries.
Because laser weapons could fire constantly without wasting ammunition, military technology experts have theorized they could one day be useful in combatting the small, remotely operated quadcopter drones that ISIS has used.
Ground-based laser weapons also are expected to be an effective counter against swarming attack drones, a concept that a handful of countries are exploring.
Russia is developing a “space gas station” – a group of robots that will use lasers to recharge satellites in near-Earth orbit, say experts at the Alexander Mozhaysky Military Space Academy in St. Petersburg. The prototype for the planned spacecraft is a spherical object, with solar panels and photovoltaic modules.
Such a robotic structure will be fitted with batteries and a pulse charger based on a supercapacitor, capable of accumulating and transmitting electrical energy to orbiting satellites by laser.
The result of the investigation conducted and released recently by the National Transportation Safety Board revealed that the lack of proper training on the touchscreen interface caused the crash that killed 10 persons and 58 others in a ship.
The collision between an oil tanker and destroyer USS John McCain took place on August 2017. The investigation report states that the sailors in charge of the helm lost control that leads them to direct the ship towards the oil tanker instead of going the opposite way.
Units of forward-positioned Army soldiers may not have quick access to battery recharging, and may depend entirely on their batteries for night vision, radios, small soldier-worn sensors, portable laptops for drone control, and other combat-essential items.
This new effort focuses on creating an entirely new fuel cell over the next five years that seeks to replace hydrogen with methanol for smaller, safer, and more efficient electricity-generating fuel cells for soldiers in combat.
The arrival of 5G and the trans-Pacific trade war are changing the vendor business.
At least that’s the experience of Ericsson, a supplier to two South Korean telcos rolling out the world’s first 5G networks.
South Korea’s early charge into 5G technology has meant the Swedish vendor has changed the way it delivers its solutions.
It is continuously upgrading its network software, a major departure from the traditional approach of “dropping two software versions a year,” said Fredrik Jejdling, Ericsson executive VP and head of business area networks.
“In order to keep up continuous improvement of the networks we do it twice per month, every second week.
Solar panels have been a great benefit to the world’s interest in deriving electricity from alternative energy sources. However, one drawback to the technology is that the panels and cells themselves are created from toxic and non-environmentally friendly materials.
Engineers at Washington University in St. Louis—working with the Department of Energy (DoE)–aim to help solve this problem with a discovery that paves the way for nontoxic perovskite solar cells.
The team—led by Rohan Mishra, assistant professor of mechanical engineering and materials science in the McKelvey School of Engineering–has discovered a new semiconductor comprised of potassium, barium, tellurium, bismuth, and oxygen that could replace lead-based semiconductors used in perovskite solar cells.
