Good morning! Julian Spector starts us out with a blast from battery technologies past. Inlyte Energy aims to commercialize a 1980s-designed iron-salt battery, and just secured a partnership with utility Southern Co. for a large-scale test.

 

Next up, Jeff St. John dives into Prisma Photonics’ fiber optic-powered solution to detecting disruptions on high-voltage transmission lines. And Clare Fieseler talks to New Jersey’s attorney general about why the state joined a lawsuit against President Trump’s anti-wind order.
