This is an animation of the device built by Convergent Scientific. CSI is a Washington state startup working on polywells/fusor technology. This was an early prototype. The device is a straight copper wire, bent into this diamond shape. Up to 1,500 amps flows through the wire (as of Fall 2013). The direction of the current was assumed and is shown in red. At that current, the wire can overheat - so a fluorinert coolant layer accompanies the wire. CSI reported that the coolant layer was inside the copper wire, and had a lackluster performance. This layer is not shown. The moving current makes a magnetic field shown in blue. This field is different from WB6. CSI built this device on the idea that the magnetic mirror effect was independent of field direction. This video is not affiliated with CSI.
