A cavitation based bubble compression process using a mix of Lithium 7 fluoride and lithium 7 hydride salt using ultrasound might also work.

Each comprises a chamber containing a liquid (host) metal such as lithium or an alloy thereof. Acoustical horns in the chamber walls operate to vary the ambient pressure in the liquid metal, creating therein small bubbles which are caused to grow to maximum sizes and then collapse violently in two steps. In the first stage the bubble contents remain at the temperature of the host liquid, but in the second stage the increasing speed of collapse causes an adiabatic compression of the bubble contents, and of the thin shell of liquid surrounding the bubble. Application of a positive pressure on the bubble accelerates this adiabatic stage, and causes the bubble to contract to smaller radius, thus increasing maximum temperatures and pressures reached within the bubble. At or near its minimum radius the bubble generates a very intense shock wave, creating high pressures and temperatures in the host liquid. These extremely high pressures and temperatures occur both within the bubbles and in the host liquid, and cause hydrogen isotopes in the bubbles and liquid to undergo thermonuclear reactions. In one type of CFR the thermonuclear reaction is generated by cavitation within the liquid metal itself, and in the other type the reaction takes place primarily within the bubbles. The fusion reactions generate energy that is absorbed as heat by the liquid metal, and this heat is removed from the liquid by conduction through the acoustical horns to an external heat exchanger, without any pumping of the liquid metal https://www.google.com/patents/US4333796 On Thu, Nov 3, 2016 at 11:54 PM, Jones Beene <[email protected]> wrote: > The recent revelation from Mills/ BrLP … that after 25 years and $100 > million spent, the most effective catalyst found thus far is silver… and > he uses it in the form of vapor by passing an electric arc… this scenario > raises > the question of an alternative method which could be implemented at lower > operating parameters. > > The boiling point of silver is almost 4000F (2190 C) which is out of the > question for most experimenters.
