Abstract

Variable speed of light (VSL) is an emerging concept in Physics which
states that the speed of light is not constant. Using this theory it is
shown in our earlier work [1], that relativistic particle by itself acts as
an energy source by virtue of variable speed of light. As a continuation
to this work we determine the optimum speed of the particle at which
maximum power transfer takes place.

VSL Theory & Our Earlier Contribution

• The Variable Speed of Light (VSL) concept states that
“ The speed of light in a vacuum, usually denoted by c, may
not be constant in some cases”

• In our earlier work we have shown that

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

• We have provided a theoretical proof which states that

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

PROOF OF RELATIVISTIC PARTICLE
USE AS ENERGY SOURCE

Extreme Case Example

• Special theory of relativity for a particle with zero velocity

E = mc2

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

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

General Case Proof

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

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

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

• 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)

General Case Proof

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

vr = c – v = constant

• Therefore Special Relativity Equation becomes

E = mc3/(c2 – (c - vr) 2)1/2

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

P =dE/dt = dE/dc. dc/dt = dE/dc (-ε)

General Case Proof

• 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

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

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

Power of a relativistic particle

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

• Probably if we can have a relativistic particle travelling at
this 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 is
maximum

• Since relativistic particle is an energy source, the sign of
P 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 be
negative 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

VSL theory is a solution to energy crisis!

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

• The optimum speed of the particle at which maximum
power transfer happens is when the speed of the particle
approaches the speed of light

• This has been shown using theoretical method and using
simulations

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

• However the exact pragmatic technique is still an open
area of research
