Ungrounded Lightning (62228) writes "Just noticed that the Navy has started the contracting process to fund EMC2's construction of a polywell fusion research device. So it looks like the work on Busard's design is proceeding. This implies that the last round went well enough that the Navy thinks there's potential for a practical power generation device and is willing to fund the engineering work to get to it. From the wording it appears to be a testbed for an ion injector. Seems to me that if they're trying to get the ions into the bottle they're confident that the reaction works and are going for continuous, rather than pulsed, operation. Let's hope this is also either a full-sized prototype or at least a version scaled up enough to test the scaling laws."
