West Japan Railway Unveils Humanoid Robot for Maintenance Tasks

July 11, 2024

It resembles a malevolent robot from 1980s sci-fi, but West Japan Railway’s new humanoid employee was designed with nothing more sinister in mind than a spot of painting and gardening. Starting this month, the machine, which features a crude head and coke-bottle eyes mounted on a truck that can drive on rails, will be put to use for maintenance work on the firm’s network.

The operator sits in a cockpit on the truck, “seeing” through the robot’s eyes via cameras and operating its powerful limbs and hands remotely. With a vertical reach of 12 meters (40 feet), the machine can use various attachments for its arms to carry objects as heavy as 40 kilograms (88 pounds), hold a brush to paint, or use a chainsaw. Initially, the robot’s primary tasks will focus on trimming tree branches along rails and painting metal frames that hold cables above trains, according to the company.

World’s First Anode-Free Sodium Solid-State Battery Revolutionizes Energy Storage

July 11, 2024

A team of researchers has combined the best battery technologies to create the world’s first anode-free sodium solid-state battery. This innovative design uses a stable solid electrolyte and pressure to form dense sodium metal. An aluminum current collector ensures efficient, repeatable sodium plating and stripping at high capacities and speeds.

This new type of battery will be less expensive and less harmful to the environment since the anode is removed, and sodium, which is cheap and plentiful, is used instead of lithium. “Although there have been previous sodium, solid-state, and anode-free batteries, no one has been able to successfully combine these three ideas until now,” said Grayson Deysher, a Ph.D. candidate at UC San Diego and first author of the study.

Revolutionary NTNU Technology Harnesses Industrial Waste Heat for Clean Water Production

July 10, 2024

Researchers at the Norwegian University of Science and Technology (NTNU) have developed an innovative technology that addresses two significant environmental challenges: utilizing industrial waste heat and generating clean water. This breakthrough was highlighted in a recent university press release.

Industrial heat is a major component of global energy consumption. After being used in industrial processes, a significant portion of this heat is typically wasted, released into oceans or the atmosphere. In Norway alone, it is estimated that 20 TWh of heat is wasted annually—equivalent to half the energy demand of Norwegian households or the energy used for heating homes. Kim Kristiansen, a doctoral researcher in NTNU’s Department of Chemistry, sought a more efficient way to repurpose this wasted energy.
