    ON

    BUBBLE POWER

  • INTRODUCTION The power generation is based on principle of sonofusion.

    y Sonofusion was derived from a related phenomenon, sonoluminescence.

    y At one day it may become a revolutionary new energy source.

    y Sonofusion Research team from various organizations have joined forces to create acoustic fusion technology energy consortium (AFTEC) to promote the development of sonofusion.

  • SONOLUMINESCENCE y When a gas bubble in liquid is excited by an

    ultrasonic acoustic waves, it can emit short flashes of light of extreme temperatures inside the bubble.

    y These flashes of light, known as sonoluminescence, occur as the bubble implodes.

    Chemical reactions occurs &yield of photons and ions formed

    y Gas bubbles in liquid convert sound energy into liquid.

    y It is also called as single bubble sonoluminescenece involve a single gas bubble trapped inside flask by a pressure field.

  • 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.

  • BASIC REQUIREMENTS Vacuum pump

    Pyrex flask

    Piezoelectric crystal

    Wave generator

    Amplifier Neutron generator

    Neutron and gamma ray detector

    Photomultiplier

    Microphone & speaker

    y Dueterated acetone(C3D6O).

  • HOW SONOFUSION WORKS Action of vacuum pump to remove natural occuring gas

    bubbles in liquid because they cant withstand high temparature&presure.

    Fill the flask with deuterated acetone because this atoms can easily undergoes fusion&fiuid can withstand high tension without unwanted bubble.

    For initiation an oscillating voltage of 20kHz applied to the ring through wave generator&amplifier,then it contract&expand,flask send pressure wave(max 1500kpa ,min -1500kpa) through liquid.

    Fire a pulsed neutron generator when pressure reaches to lowest point.

  • ACTION IN THE FLASK

    Stage (1)

    The fast moving neutrons

    may knock atoms

    nuclei&give their kinetic

    energy to liquid

    moleculesflying in the

    flask create a bubble

    cluster(about 1000

    bubbles) in the

    deuterated acetone

    liquid.

  • Stage (2)

    y By firing neutron generator in low

    pressure i.e, negative

    pressure in the liquid

    makes the bubbles swell

    100000 times in size

    (from nano to

    millimeter-scale).

    pediain.com

  • Stage 3 y The liquid pressure

    turns positive and

    compresses the

    bubble, causing them

    to implode with great

    violence&creates

    spherical shockwaves

    within bubbles.

    pediain.com

  • Stage(4)

    y The implosion creates an instantaneous

    pressure of 10 trillion

    kilopascals and

    temperature of more

    than 100 million

    degree C, making the deuterium fuse.

  • FUSION REACTION

    y Deuterium-Deuterium fusion has two probable outputs, helium and a 2.45-MeVneutron or tritium and a proton.

    y The energy of 2.45MeV neutron can be harnessed in a reactor to create water vapor &drive an electricity generator.

  • EVIDENCE TO SUPPORT TABLETOP NUCLEAR FUSION DEVICE

    y We gather two kinds of evidence that the deuterium is fusing.

    y The first is by measuring levels of another hydrogen isotope tritium

    y The second is neutron emissions detected by the neutron detector.

  • ADVANTAGES

    y It is self sustaining.

    y Easily control.

    y Produce more energy than it consumes.

    y Low cost.

    y Easily available raw materials.

    y Environmental friendly.

  • APPLICATIONS y 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.

    y Compact detectors for security applications.

    y To analyze molecular structure of materials.

    y Machines that cheaply manufacture new synthetic materials & efficiently produce tritium, which is used for

    medical imaging to watch dials.

  • FUTURE DEVELOPMENTS y Fully self-sustained.

  • CONCLUSION y For more than half a century, thermonuclear fusion has

    held out the promise of cheap, clean and virtually limitless

    energy.

    y 1 gram of deuterium,an isotope of hydrogen,would be equal to produced by burning 7000liters of gasoline.

    y Deuterium abundent in ocean water ,1 cubic kilometer of seawater could supply all the worlds needs for several

    hundred years.
