It’s been a good few weeks for research on “greening” our energy supply, with new reports emerging of energy-efficient transistors, nanoparticle-based sensors that detect hydrogen leaks, and even the apparent contradiction of a solar cell that keeps working after sunset. In the longer term, it’s also possible that new configurations of high-temperature superconductors could enable these materials to conduct electricity without resistance at even higher temperatures, broadening their applications and reducing energy usage in certain areas. Keep up with these and other developments on our website.
