Abstract: A hybrid energy harvesting scheme and system integrating radio frequency (RF) electromagnetic wave and solar energy based on optically transparent metasurface is proposed and constructed for ...

That trade-off means a lot of energy is needed to extract the absorbed water, which is typically achieved by heating the sorbents. Releasing water by physically compressing a sorbent is a “promising ...

The shipping container-sized machine will produce up to 1,057 gallons of water daily and can be installed at data centers, ...

A new wave of start-ups are trying to harvest emissions-free energy from inside the Earth, but the industry still faces ...

Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250229. Programmable metasurface (PM), also termed as reconfigurable intelligent surface (RIS), have emerged as a ...

What do nine-time Grammy-winning billionaire Rihanna, stunning beaches, and a potential 50-megawatt wave-energy project have in common? Barbados! The island nation is deploying a unique type of wave ...

New research presents a gyroscopic wave energy converter that absorbs up to 50% of wave energy across frequencies, nearing maximum efficiency and guiding improved designs. (Nanowerk News) Ocean waves ...

Abstract: Wave energy is a promising renewable source that can help reduce greenhouse gas emissions. Yet, Wave Energy Converters (WECs) still face challenges in extracting energy efficiently under ...
