Abstract

Variable speed of light (VSL) is an emerging concept in Physics whichstates that the speed of light is not constant. Using this theory it isshown in our earlier work [1], that relativistic particle by itself acts asan energy source by virtue of variable speed of light. As a continuationto this work we determine the optimum speed of the particle at whichto this work we determine the optimum speed of the particle at whichmaximum power transfer takes place.

INTRODUCTIONINTRODUCTION

• The Variable Speed of Light (VSL) concept states that“ The speed of light in a vacuum, usually denoted by c, maynot be constant in some cases”

• In our earlier work we have shown that

“Relativistic particle by virtue of VSL concept posses an

VSL Theory & Our Earlier Contribution

“Relativistic particle by virtue of VSL concept posses anenergy which could solve the global energy crisis”

• We have provided a theoretical proof which states that

“Relativistic particle without decrease of mass as innuclear reaction is a potential renewable source of energy”

PROOF OF RELATIVISTIC PARTICLE PROOF OF RELATIVISTIC PARTICLE USE AS ENERGY SOURCE

• Special theory of relativity for a particle with zero velocity

E = mc2

• It is evident that for a relativistic particle to be used asenergy source either m or c should decrease over time

Extreme Case Example

Relativistic Particle as Energy Source Proof:

• Even if m does not decrease as in nuclear reactions• It is very evident that as c is slowly decreasing over time• Hence there is an inherent energy in relativistic particle by

virtue of VSL theory that make it act as an energy source

• Special theory of relativity for a particle with velocity ‘v’

E = mc3/(c2 - v2)1/2

• It has been proved using measurements that the magnitudeof change in ‘c’ is infinitesimal

General Case Proof

• Assumption is Special Relativity Theory still holds true &above equation is valid even if ‘c’ decreases very slowly.

• Let this slow decrease in speed of light be ε. This implies,

dc/dt = – ε (infinitesimal negative constant)

• We assume that the relative velocity between c & v isconstant.

vr = c – v = constant

• Therefore Special Relativity Equation becomes

General Case Proof

E = mc3/(c2 – (c - vr) 2)1/2

• For relativistic particle to act as energy source, the powerwhich is the rate of change of energy dE/dt should be –ve.

P =dE/dt = dE/dc. dc/dt = dE/dc (-ε)

• This implies, for relativistic particle to act as energy source,dE/dc should be +ve.

• Differentiating E = mc3/(c2 – (c - vr) 2)1/2 with c, we get

dE/dc = m[3c2(c2 – (c-vr) 2)-c3(c- (c-vr))]/(c2 – (c - vr) 2) 3/2

= m[c2(vr)(2c+3v)] /(c2 – (c - vr) 2) 3/2

General Case Proof

= m[c (vr)(2c+3v)] /(c – (c - vr) )

• Hence dE/dc is always +ve,since vr > 0 as v < c still hold true

• This implies all particles which obey special theory ofrelativity is as an energy source.

MAXIMUM POWER TRANSFERMAXIMUM POWER TRANSFER

Power of a relativistic particle

• The next question is at what speed ‘v’ of the particlecorresponds to the situation with maximum power

• Probably if we can have a relativistic particle travelling atthis speed ‘v’ maximum power could be transferred

• The power P of a relativistic particle is given by

P = - ε m[c2(vr)(5c-3vr)] /(c2 – (c - vr) 2)3/2

= - ε m[c2(c-v)(2c+3v)] /(c2–(v)2)3/2

Pabs = ε m[c2(c-v)(2c+3v)] /(c2 –(v)2)3/2

Max Power Transfer : Theoretical Method

• Objective: To find the v for which absolute value of P ismaximum

• Since relativistic particle is an energy source, the sign ofP would be negative

• We need to set dPabs/dv should be equal to zero

• A check needs to be done to see if dPabs2/d2v should benegative at that v.

• It can be shown by derivations that

dPabs/dv = ε m[c2(c-v)( c2+cv+3v2)] /(c2 –(v)2)5/2

CONCLUSIONSCONCLUSIONS

VSL theory is a solution to energy crisis!

• It has been shown that relativistic particle is an energysource by virtue of the variable speed of light

• The optimum speed of the particle at which maximumpower transfer happens is when the speed of the particleapproaches the speed of light

• This has been shown using theoretical method and usingsimulations

• Thus it has been shown that the VSL concept could bepotentially used to solve the present global energy crisis;

• However the exact pragmatic technique is still an openarea of research
