A Fairfield startup company is working on a solution to prevent accidents in which young children swallow button batteries. The company CEO says at least 3,500 button battery ingestion injuries happen in the U.S. each year. Trista Hamsmith, whose 18-month-old Reese Hamsmith died after swallowing one, says she supports this new technology. “What I can …

Oct 17th 2020 RADIO WAVES do not travel well underwater. That is why ships employ sonar rather than radar to plumb the briny depths. Messages broadcast through the ocean need to be sonic, too. For that purpose people often use acoustic modems, which can turn electronic signals into sound, and vice versa, like an old-fashioned …

The U.S. may have fallen behind Asia and Europe in battery manufacturing, but a number of well-funded companies are looking to get the country back in the game with a technology that could supersede today’s lithium-ion chemistries. Companies including Ionic Materials, QuantumScape, Sila Nanotechnologies, Sion Power and Solid Power are developing all-solid-state batteries (ASSBs) that are expected …
