    Has anyone considered using a diamond anvil to create fusion?

    Is this possible?

    Either way why?

    If possible could this system be used to create a net energy effect?

    Would there be any significant additional problems with this concept?

    To get fusion you need a high enough temperature (10-100million Kelvin). Obviously increasing the pressure of a substance will cause it to heat up, and some diamond anvil cells are design to use lasers to provide additional heating, but only to a few thousand degrees. Diamond anvils can exert such high pressures becuse the diamond is very strong and hard. However diamond’s melting point is around 3500C, at which point it will not be able to maintain the pressure. No solid or liquid substace can exist in the regeme where fusion works, everything is plasma.

    So, no it won’t work.

    Inertial confinement fusion as done in the laser facilities such as NIF does work by excerting a huge pressure, but that is done by the laser (via a gold cylinder called a hohlraum) burning off the outside of a frozen pellet of deuterium (or D-T in future), so the centre of the pellet impodes and heats up under the massive pressure shock wave. Think of the pellet as a sphere of rockets all with their noses pointed to the centre. When the rockets all fire their noses are all crushed together. The centre of the pellet then heats up to the 100million degrees needed to ignite the fusion reaction (hopefully) which propagates out through what is left of the pellet like a little bomb. It is still very much debateable whether this will ever be able to break even.

    Hah! A mere 100 million°! And FF operates at 1-2 billion°!! Obviously much more advanced. 🙂 :cheese:

    Recently, in a previous post I have suggested a series of focus fusion experiments that use light water and heavy water as the fissile medium in the FF reactor in preference to deuterium or boron gas.

    The density of deuterium available in heavy water would be orders of magnitude greater than those availed in gas.

    Another type of experiment would include boron nano powder suspended in water to increase the density of boron available for plasmoid fusion. Cavitation chemistry has demonstrated that metal nano-powders will vaporize in plasma.

    These experiments would produce collapsing cavitation bubbles whose pressure profile is high as follows:

    “Shock wave emission upon the collapse of a cavitation bubble attached to a rigid wall was investigated using high-speed photography with 200 million frames/s and 5 ns exposure time. At a distance of 68 μm from the bubble wall, the shock pressure is 1.3 ± 0.3 GPa. The shock pressure decays proportionally to r exp−1.5 with increasing distance from the bubble. An estimation of the peak pressure at the bubble wall reveals a pressure of about 8 GPa. A major part of the shock wave energy is dissipated within the first 100 μm from the bubble wall.”

    It is reasonable to expect that the internal maximum pressure inside a free floating cavitation bubble is somewhat greater than 8 GPa. In comparison, the maximum pressure applied in a diamond anvil is only about 1 or 2 GPa.

    If a FF plasmoid can be produced inside a collapsing cavitation bubble, I would be interested in the fusion results at 8 GPa pressure compared to those produced in a gas at ambient pressure.

    In all these suggested experiments, fusion based transmutation should be determined through spectroscopy.

    AFAIK, the cavitation-fusion experiments have failed because the energy dissipation is so fast that no actual fusion events occur. The Gods of Chaos are interfering.

    IMHO, water is a poor cavitation medium. Mercury is about 100,000 times better and molten fluoride salt is even better than that. There are cavitation methods using oil that are reported to result in over unity energy gain. So in summation, it all depends.
