Could powerful lasers unlock cheap fusion power?
A Denver-based start-up plans to use powerful lasers to spark a fusion reactor.
That knowledge caught the attention of two young graduate students working at the Los Alamos National Laboratory in the late 2000s, Conner Galloway and Alexander Valys. "I suppose my scepticism is, I haven't yet even seen a persuasive conceptual diagram of how you manage the process of taking energy out while keeping the fusion reaction going," says Prof Ian Lowe at Griffith University in Australia. Another challenge is that the fusion reaction produces high energy particles that will degrade steel, or any other material that lines the reactor core.
