New Quantum Technology To Make Charging Electric Cars As Fast as Pumping Gas
Posted by Shubham Ghosh Roy in categories: Elon Musk, energy, quantum physics, sustainability
Quantum charging will cut the charging time of electric vehicles from ten hours to three minutes.
Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. As such, much research has been pursued in order to develop alternative sources of energy, most of which utilize electricity as the main energy carrier. The extensive R&D in renewables has been accompanied by gradual societal changes as the world adopted new products and devices running on renewables. The most striking change as of recently is the rapid adoption of electric vehicles. While they were hardly seen on the roads even 10 years ago, now millions of electric cars are being sold annually. The electric car market is one of the most rapidly growing sectors, and it helped propel Elon Musk to become the wealthiest man in the world.
Unlike traditional cars which derive energy from the combustion of hydrocarbon fuels, electric vehicles rely on batteries as the storage medium for their energy. For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early electric vehicles. However, gradual improvement in battery technologies eventually allowed the drive ranges of electric cars to be within acceptable levels in comparison to gasoline-burning cars. It is no understatement that the improvement in battery storage technology was one of the main technical bottlenecks which had to be solved in order to kickstart the current electric vehicle revolution.

Space WiFi? A new startup wants to give NASA’s moonbase an internet connection
Posted by Atanas Atanasov in categories: economics, internet, space
If we are to set up a permanent base on the Moon, we will need some solid connection.
A space startup company is trying to make that happen. Aquarian Space recently announced receiving $650,000 in seed funding to develop a possible broadband internet connection that would link the Earth to the Moon, and maybe even Mars.
The company aims to deploy its first communications system to the Moon by 2024 in anticipation of increased demand from planned space missions to the Moon and beyond, both public and private ventures.

Malware That Can Survive OS Reinstalls Strikes Again, Likely for Cyberespionage
Posted by Shubham Ghosh Roy in category: cybercrime/malcode
A new malware strain that can survive operating system reinstalls was spotted last year secretly hiding on a computer, according to the antivirus provider Kaspersky.
The company discovered the Windows-based malware last spring running on a single computer. How the malicious code infected the system remains unclear. But the malware was designed to operate on the computer’s UEFI firmware, which helps boot up the system.
The malware, dubbed MoonBounce, is especially scary because it installs itself on the motherboard’s SPI flash memory, instead of the computer’s storage drive. Hence, the malware can persist even if you reinstall the computer’s OS or swap out the storage.

Bex: A walking, rolling quadruped robot that can carry a person around
Posted by Shubham Ghosh Roy in categories: food, robotics/AI
Officials and engineers at Kawasaki have unveiled Bex, a quadruped robot that can walk, roll around and even carry a human passenger on its back—at this year’s 2022 International Robot Exhibition in Tokyo. At the exhibition, Bex was configured to look like an Ibex, a type of wild goat, which is where it gets its name.
Bex was created as part of an effort at Kawasaki the company calls a “robust humanoid platform” with a project called Kaleido. Most such efforts from the project have involved robots that are halfway between human-like robots and wheeled bots. Bex appears to be an aberration—it is a quadruped with wheels on its knees. The robot can walk around, similar in many respects to a quadruped from Boston Dynamics, though much slower. But it also squats down to its knees, locks its joints and fires up a motor that drives the robot around like a car. Bex can also carry cargo (up to 100 kilograms) such as crops or humans. At the exhibition, Bex was mounted by an engineer and ridden in circles like a pony. The team at Kawasaki has also made the robot a little glitzier than many of its competitors—it has flashing lights that run up and down its neck and antlers.
