Compact Fusion Systems recently got funding to push this approach. On LinkedIn they announced purchase of surplus high-energy capacitors (from the old Shiva Star at AFRL) to build a prototype. They seem to have taken to hear some lessons learned from previous experiments (cannot assume lossless compression, must pay attention to RT instabilities, must think about vaporization of first-wall). One downside to a fully liquid blanket: the peak temperature is limited by the vapor pressure of the first wall, which in turn is limited by the impurity tolerance of the plasma. In a non-imploding device, it would be possible to run the majority of the blanket at a higher temperature & separate that from the cooler first-wall liquid. Of course, this puts some solid material closer to the neutrons, so YMMV. https://arpa-e.energy.gov/sites/default/files/ALPHA_TURCHI.pdf https://arpa-e.energy.gov/sites/default/files/ALPHA_TURCHI.p... https://arpa-e.energy.gov/sites/default/files/06_TURCHI.pdf https://arpa-e.energy.gov/sites/default/files/06_TURCHI.pdf
