Welcome to Tech Beat, your daily look at the stories shaping our world.
In Ukraine, officials are raising serious concerns after a Starlink missile tracker went dark during a new wave of Russian air strikes on Tuesday. The system, owned by Elon Musk, failed at a critical moment, leaving Ukrainian forces without a tool they had come to rely on. It is a stark reminder of how deeply modern warfare now depends on commercial technology infrastructure, and how fragile that dependency can be.
Turning to an encouraging development in energy and computing, researchers at Lehigh University have built a working prototype of a concrete thermal battery capable of storing one hundred fifty kilowatt hours of energy and withstanding temperatures up to five hundred degrees centigrade. The system is designed to capture waste heat from data centers and turn it into usable energy, potentially transforming one of the tech industry's biggest environmental liabilities into a resource.
And in the world of open source software, a developer is proposing a new model that challenges some long-held assumptions. The idea is simple but provocative: keep a codebase closed to pull requests while remaining fully open to remixing and forking. It asks whether collaboration and control might actually coexist in ways the community has not fully explored yet.
