Fusion Vibration

First of all, the mass of the iron balls, depending on the diameter, would be considerable. It would be impractical to vibrate iron balls to cause fusion in deuterium.

On a first principle level, the coupling between atoms of Fe and D is just impractical.

Now, consider that a 10 keV D has a speed of about 978 km/s, it does not seem practical to move a massive steel ball with a velocity of this magnitude.

Now consider that the velocity of sound in steel is on the order of 5 km/s, so the velocity of the deuteron at 10 keV is 2 orders of magnitude greater than the acoustic velocity in steel.

Now consider that 1 eV is equivalent to 11605 K, then a 10 keV deuteron has an equivalent temperature of 116 million K, and for fusion of a pure D plamsa, one would probably want a temperature of 50-100 keV. The melting point of steel is about 1700 K.

At the center of the Sun, where its density reaches up to 150,000 kg/m³ (150 times the density of water on Earth), thermonuclear reactions (nuclear fusion) convert hydrogen into helium, producing the energy that keeps the Sun in a state of equilibrium. About 8.9×10³⁷ protons (hydrogen nuclei) are converted to helium nuclei every second, releasing energy at the matter-energy conversion rate of 4.26 million tonnes per second or 383 yottawatts (9.15×10¹⁶ tons of TNT per second). Models predict that the high-energy photons released in fusion reactions take about a million years to reach the Sun's surface, where they escape as visible light. Neutrinos are also released in the fusion reactions in the core, but unlike photons they very rarely interact with matter, and so almost all are able to escape the Sun immediately.

The core extends from the center of the Sun to about 0.2 solar radii, and is the only part of the Sun where an appreciable amount of heat is produced by fusion: the rest of the star is heated by energy that is transferred outward. All of the energy of the interior fusion must travel through the successive layers to the solar photosphere, before it escapes to space.

The core of the sun is not Fe. The sun is primarily H and He.

Core of Sun - http://en.wikipedia.org/wiki/Sun


The core is a plasma, a highly ionized gas, so it does not vibrate in the way to which was alluded in the first post.

Also, I should point out that the sun is fusing H rather than D or T, although D and T are likely present in small quantities. The temperature in the core is believed to be about 13.6 million K, 1170 ev (1.17 keV) which is relatively cool. However the particles (nuclear) density in the suns core is about a trillion times denser than the hottest magnetically confined plasmas we can produce on earth.
