In Sonofusion a piezoelectric crystal attached to liquid filled Pyrex flask send pressure waves through the fluid, exciting the motion of tiny gas bubbles. The bubbles periodically grow and collapse, producing visible flashes of light. The researchers studying these light emitting bubbles speculated that their interiors might reach such high temperature and pressure they could trigger fusion reaction. Tiny bubbles imploded by sound waves can make hydrogen nuclei fuse- and may one day become a revolutionary new energy source.
When a gas bubble in a liquid is excited by ultrasonic acoustic waves it can emit short flashes of light suggestive of extreme temperatures inside the bubble. These flashes of light known as sonoluminescence, occur as the bubble implode or cavitates. It is show that chemical reactions occur during cavitations of a single, isolated bubble and yield of photons, radicals and ions formed. That is gas bubbles in a liquid can convert sound energy in to light.
Sonoluminescence also called single-bubble sonoluminescence involves a single gas bubble that is trapped inside the flask by a pressure field. For this loud speakers are used to create pressure waves and for bubbles naturally occurring gas bubbles are used. These bubbles can not withstand the excitation pressures higher than about 170 kilopascals. Pressures higher than about 170 kilopascals would always dislodge the bubble from its stable position and disperse it in the liquid. A pressure at least ten times that pressure level to implode the bubbles is necessary to trigger thermonuclear fusion. The idea of sonofusion overcomes these limitations.

For more than half a century, thermonuclear fusion held out the promise of cheap, clean and virtual limitless energy. In an experimental research, which is not yet concluded, it is found that deuterium, a material which is abundant in ocean water, when made to tiny bubbles, which can be imploded by using sound waves, can make hydrogen nuclei fuse. This phenomenon can be called as sonofusion. This is very much useful to produce bubble power. 1 km3 of sea water could, in principle, supply the entire world?s electrical energy need for several hundred years. At one day, it becomes a revolutionary new energy source.

INTRODUCTION

 

  • Tiny bubbles imploded by sound waves can make Hydrogen nuclei ? and may one day become a revolutionary new energy source.

 

  • The bubbles violently collapse, can cause some of the deuterium nuclei to undergo fusion.
  • Unleashed through a fusion reactor of some sort, the energy from 1 gm of deuterium, an isotope H2, would be equivalent to that produced by burning 7000 liter of petrol.

 

  • Deuterium is abundant in ocean water.
  • We have yet to identify an economically viable fusion reactor technology that can consistently produce more energy that it consumes.
