  1. SEMINAR ONBUBBLE POWERTHE REVOLUTIONARY NEW ENERGY SOURCE BY: VISHNU.S ROLL.NO.4428 S7.ME

  2. INTRODUCTION • Sonofusion Research team from various organizations have joined forces to create acoustic fusion technology energy consortium (AFTEC) to promote the development of sonofusion. • It was derived from a related phenomenon, sonoluminescence. • Sonofusion involves tiny bubbles imploded by sound waves can make hydrogen nuclei fuse-and may one day become a revolutionary new energy source.

  3. SONOLUMINESCENCE • When a gas bubble in 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 implodes, or cavitates. • Chemical reactions occurs .

  4. THE IDEA OF SONOFUSION • Technically known as acoustic inertial confinement fusion. • In this piezoelectric crystal attached to a liquid-filled flask send pressure waves through the fluid, exciting the motion of tiny gas bubbles. • High temperatures and pressure speculated at the bubble core . • This leading to conditions suitable for thermonuclear fusion.

  5. EXPERIMENTAL SET UP

  6. BASIC REQUIREMENTS • Pyrex flask • Vacuum pump • Piezoelectric crystal • Wave generator • Amplifier • Neutron generator • Neutron and gamma ray detector • Photomultiplier • Microphone & speaker

  7. HOW SONOFUSION WORKS • Action of vacuum pump. • Fill the flask with deuterated acetone. • For initiation an oscillating voltage of 20kHz applied to the ring. • Fire a pulsed neutron generator.

  8. EXPERIMENTAL SET UP

  9. ACTION IN THE FLASKStage (1) Neutrons flying through the flask create a bubble cluster in the deuterated acetone liquid.

  10. Stage (2) • The negative pressure in the liquid makes the bubbles swell 100000 times in size (from nano to millimeter-scale).

  11. Stage (3) • The liquid pressure turns positive and compresses the bubble, causing them to implode with great violence.

  12. Stage(4) • The implosion creates an instantaneous pressure of 10 trillion kilopascals and temperature of more than 100 million degree C, making the deuterium fuse.

  13. EXPERIMENTAL SET UP

  14. FUSION REACTION • Deuterium-Deuterium fusion has two probable outputs, helium and a 2.45-MeV neutron or tritium and a proton. • The energy of 2.45MeV neutron can be harnessed in a reactor to create water vapor &drive an electricity generator.

  15. EVIDENCE TO SUPPORT TABLETOP NUCLEAR FUSION DEVICE • We gather two kinds of evidence that the deuterium is fusing. • The first is by measuring levels of another hydrogen isotope tritium • The second is neutron emissions detected by the neutron detector.

  16. SEQUENCE OF EVENTS

  17. OTHER APPROACHES • Mainly two types: • Laser beam technique. • Magnetic confinement fusion

  18. ADVANTAGES • It is self sustaining. • Easily control. • Produce more energy than it consumes. • Low cost. • Easily available raw materials. • Environmental friendly.

  19. APPLICATIONS • The technology might one day, in theory, lead to a new source of energy. It may result in a new class of low cost energy. • Compact detectors for security applications. • To analyze molecular structure of materials. • Machines that cheaply manufacture new synthetic materials & efficiently produce tritium, which is used for medical imaging to watch dials.

  20. FUTURE DEVELOPMENTS • Fully self-sustained. neutrons

  21. Contd… • To create a full-size electricity producing nuclear generator.

  22. CONCLUSION • For more than half a century, thermonuclear fusion has held out the promise of cheap, clean and virtually limitless energy.
