A SYSTEM FOR GENERATION OF ELECTRICAL OUTPUT FROM DISSIPATED
HEAT OF A HEAT/LIGHT SOURCE
FIELD OF INVENTION
The present invention relates to the recycling of radiated thermal energy into productive form for
supplementary electrical energy requirements. More particularly, the present subject matter relates
to the utilization of the heat dissipated from the resistive load banks or like heat/light sources
followed by its conversion to electrical energy.
BACKGROUND OF INVENTION
The background of the invention relates to the reengineering different forms of energy wasted in
shop floor activities for channelling into productive usage. The heat, radiated from the sun or
generated from engines and furnaces, is often wasted. Thermophotovoltaic devices are known to
convert heat into electricity and is a promising technique to scavenge it. Thermoelectric devices
are normally made from materials capable of converting a temperature difference into electricity.
The phenomenon is reversible, i.e., if electricity is applied to a thermoelectric device, it can yield
a difference in temperature between two ends of the device. As a result, compact, simple systems
for grid energy storage can be designed using these devices that are even cheaper than batteries.
The present subject matter focuses on efficient utilization of the heat dissipated from a resistive
load bank or like heat/light sources followed by their conversion to electrical energy.
PRIOR ARTS OF THE INVENTION
There are some systems/methods known in the art for recycling of the wasted energy. These are
discussed herein below:
CN103201941A titled “Method and apparatus for generating electricity by thermally cycling an
electrically polarizable material using heat from various sources and a vehicle comprising the
apparatus” discusses a method for converting heat into electric energy. The invention discloses a
method for converting heat to electric energy which involves thermally cycling an electrically
polarizable material sandwiched between electrodes. The material is heated using thermal energy
obtained from a number of processes namely, a combustion reaction; solar energy; a nuclear

reaction; ocean water; geothermal energy; or thermal energy recovered from an industrial process.
Further, an apparatus is also described which includes an electrically polarizable material
sandwiched between electrodes and a heat exchanger for heating the material. The heat source
used to heat the material can vary from a combustion apparatus; a solar thermal collector; or a
component of a furnace exhaust device. Alternatively, the heat exchanger can be a device for
extracting thermal energy from the earth, the sun, ocean water, an industrial process, a combustion
reaction or a nuclear reaction. A vehicle is also described which comprises an apparatus for
converting heat to electrical energy connected to an electric motor. Therefore, it may be inferred
the invention discussed herein differs widely from that of the present subject matter in terms of the
purpose, method and the proposed system.
CN112262291A titled “Method for operating regenerative heat accumulator device and heat
accumulator device” relates to a method for operating a regenerative heat accumulator system,
wherein the accumulator system has at least one gas heater for heating a carrier gas, in particular
for heating air; a heat accumulator bank having a plurality of heat accumulator modules; and at
least one compressor, wherein during a charging cycle, a carrier gas heated in the gas heater flows
through at least one regenerator module, preferably through a plurality of subsequent regenerator
modules of the regenerator bank, which is hot-charged by transferring heat from the heated carrier
gas to the heat storage material of the regenerator modules, and cools the carrier gas during the
charging process, wherein the carrier gas is fed to the subsequent regenerator modules for charging
if, after charging of the regenerator modules, the carrier gas temperature reaches or exceeds the
lowest charging temperature for the subsequent regenerator modules in the regenerator bank, and
wherein if the carrier gas temperature falls below the minimum filling temperature for the
subsequent regenerator module, the carrier gas is recirculated and the carrier gas is fed to the
compressor upon recirculation and fed back to the gas heater after compression to reheat the carrier
gas.
An Indian Patent application Number “202141010521” titled “Portable IOT based hybrid power
generator for commercial purpose” discloses a system which use photovoltaic (PV) devices to
convert chemical and physical energy, such as inorganic chemical and pouches to PV to an
electrical energy reservoir that may continuously retain a portion that is not yet obtained and stored.
The invention relates to the usage of the thermoformed of disparate metals forming a tropical
biometrical conjunction that produces the Seebeck effect. Consequently, the radiant energy is

converted to electrical energy. The invention further discloses a collector made up of vertical
metallic strips both affixed to a hollow non-carrying rod further affixed to a horizontal moving
carrier connected to said non-carrying base. The base is affixed to said carrier with sheets that are
in turn affixed by slotted connections. But the invention disclosed in the current system differs in
a way that here a different thermoelectric sensor in a totally different system (a series of k type
thermocouples) for a resistive load bank has been used. In other words, the above disclosure will
not work for the purpose and equipment specification defined in the present subject matter.
Moreover, the present disclosure provides an extended battery storage for the energy to be stored
at rated values.
An Indian Application No. 202147008849 titled “Device, plant and method for the storage and
transfer of thermal energy of solar origin” relates to the use of the high temperature thermal power
stored in the fluid bed in conjunction with thermophotovoltaic (TPV) technology. TPV technology
requires thermal emitters at high temperature (>600°C) in order to produce electricity from thermal
radiation. As disclosed in the invention, TPV thermal emitters are located immersed in or exposed
to a hot particle fluidized bed, protected by suitable layers of high temperature resistant material,
like ceramic or refractory walls. The high temperature fluidized bed provides thermal power to the
TPV cells thus producing electricity. The basic distinguishing factor between the invention
disclosed and the present subject matter lies in the mode of power generation from the heat source.
The application of solar based effects does not fall into the categorization of thermoelectric
regeneration. These pertain to the category of renewable energy and therefore is in different format
on all fronts with respect to the present subject matter.
It is evidenced from the prior arts that there is no such system for efficient utilization of the
dissipated heat energy by converting it to the electrical output by means of thermoelectric sensors.
In pursuit of this, the present disclosure focuses on the recycling of this heat energy into electrical
energy that can be further used to operate a number of utility equipment.

existing in the prior art systems and methods.

electrical output.
It is yet another object of the present subject matter to implement thermoelectric sensors for
conversion of the dissipated heat to electrical energy.
It is still another object of the present subject matter to store the energy generated from the circuit
by suitable means and then provide it to other utility equipment.
These and other objects and advantages of the present subject matter will be apparent to a person
skilled in the art after consideration of the following detailed description taking into consideration
with accompanied drawings in which preferred embodiments of the present subject matter are

DETAILED DESCRIPTION OF INVENTION WITH REFERENCE TO THE
DRAWINGS OF THE PREFERRED EMBODIMENTS
The following is a detailed description of embodiments of the disclosure depicted in the
accompanying drawings. The embodiments are in such detail as to clearly communicate the
disclosure. However, the amount of detail offered is not intended to limit the anticipated variations
of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and
alternatives falling within the spirit and scope of the present disclosure as defined by the appended
claims.
While the embodiments of the disclosure are subject to various modifications and alternative
forms, specific embodiment thereof have been shown by way of example in the figures and will
be described below. It should be understood, however, that it is not intended to limit the disclosure
to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications,
equivalents, and alternative falling within the scope of the disclosure.
The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are
intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises
a list of components does not include only those components but may include other components
not expressly listed or inherent to such system, or assembly, or device. In other words, one or more

The present disclosure relates to an invention pertaining to technology regarding a system (100)
for generation of electrical output from the dissipated heat of a heat/light source. The principle of
working involves recycling of the wasted heat energy. There is no productive means by which this
energy can be recycled for other utilities. Welding Power sources are tested using different sets of
criteria, preferably with a static load facility. A non-inductive pure resistive load is a primary
requirement for important tests like static characteristics, load test, stalled fan test etc. The IEC
design stage stipulates that load current should be flown in the circuit as per a governing relation
between voltage and current. Therefore, resistive load bank has been considered as a source of
heat in the present subject matter. The present disclosure pertains to other sources of heat/light as
well.
Figure 1 illustrates the schematic of the regenerative system (100) for recycling of energy. It is
observed from the figure that a resistive load bank is connected to a plurality of thermoelectric
sensors (2) in series which in turn is connected to a battery storage (4). The output of the battery
storage (4) is fed into the utility equipment/instrument (5) upon requirement.
In an embodiment, the resistive load bank comprises of a plurality of coils. In a preferred
embodiment, the coils are made up of nichrome.
In an aspect, the coils are wound into a load circuit and is connected to the terminals of the supply
from which energy is sourced for dissipation.
In another aspect, a plurality of thermoelectric sensors (2) are connected to the output of the load
circuit thus referring it as a “hot junction” (1). The thermoelectric sensors (2) cover the entire range
of the hot junction (1) of the resistive load bank. The other end of said thermoelectric sensor is in
reference to the room temperature serving as a “cold junction” (3). The difference in temperatures
between the hot junction (1) and the cold junction (3) provides an equivalent electrical signal as
the output. Consequently, the heat dissipated from the load circuit is converted to electrical energy
by said thermoelectric sensors (2).

In a preferred embodiment, thermocouple has been used as the thermoelectric sensor and is chosen
suitably depending on the range and the values of heat energy dissipated.
In another aspect, the system (100) comprises of a battery storage (4) in order to store the output
electrical energy and deliver the rated values to the load circuit continuously or on requirement.
This is necessary as the operating conditions of the equipment/instrument do not provide a stable
output. The battery storage (4) acts as a medium to store the energy from the circuit and further
providing it to the load. The battery storage (4) has been configured to be connected live or in
isolation for powering the circuits.
In a preferred embodiment, a plurality of utility equipment (5) targeted in the present disclosure
comprises of all electrical appliances/devices with DC input power. The generated electrical output
is used either internally to power the DC operated devices in the equipment or as supply source
for DC operated devices in nearby environment.
Further in an embodiment, the proposed system (100) holds true for conversion of heat energy
dissipated from any other heat source or light sources as well.
In an embodiment, the resistance value for a particular value of current in the circuit is calculated
on the basis of reference voltage. This provides fixed values of resistances for different load
settings of 50A, 100A, 150A, 200A, 250A, 310A, 350A, 400A and 500A.
In an aspect, although it is theoretically possible to extend this to any current load, considering the
practical requirements and utility of the power source, it is never expected to cross 400A.
Therefore, in a preferred embodiment, the proposed system (100) operates with the load settings
in the range of 50-400 A. However, the maximum load of 500A is considered for the design of the
system (100) and is deemed sufficient for different types of inverter based power sources.
Moreover, in a preferred embodiment, the current carried by the resistive coils for period of
duration varies between ten minutes to four hours depending on the testing requirement. The heat
dissipation is significant for all duration and in fact longer the duration, the continuous fixed heat
is dissipated through the coils as the resistances do not vary over the time period. Thermocouples

convert this heat gradient to an equivalent electrical signal and the generated energy is stored in a
battery.
Working of the invention
The present subject matter aims towards recycling and further utilization of the heat energy
dissipated from the resistive load bank or like heat/light sources (1). Herein, induction free resistive
load bank is used in evaluating the equipment’s capability of supplying the rated power. The
present disclosure details a system (100) in which the emitted heat from the resistive load bank is
converted into a usable form of energy by using a multitude of thermoelectric sensors (2) that
convert the thermal gradient into an equivalent electrical voltage as a result of the diffusion of
electrons from the hot junction (1) to the cold junction (3) of the thermoelectric sensors (2). The
generated voltage is further used to charge a battery storage (4) that could supply the required
energy for powering the utilities (5). The heat dissipated from the coils even at the minimum input
supply is sufficient enough to generate a heat gradient that induces the voltage output thus
indicating that the minimal operating conditions as sufficient for working of the circuit. The
electrical output at the higher extreme generates voltage at higher value that is stored in the battery.
The purpose of battery is to define the constant delivery of rated parameters to the load considering
the inconsistency with which the operating conditions may work out for power generation.
Advantages of the invention
The system (100) described in the present disclosure is having the following advantages:
a) Utilization of the heat energy which is otherwise wasted.
b) Storage of the converted electrical energy that is used for operation of utility equipment
(5).
It should be noted that the description and figures merely illustrate the principles of the present
subject matter. It should be appreciated by those skilled in the art that conception and specific
embodiment disclosed may be readily utilized as a basis for modifying or designing other
structures for carrying out the same purposes of the present subject matter. It should also be
appreciated by those skilled in the art that by devising various systems that, although not explicitly
described or shown herein, embody the principles of the present subject matter and are included
within its spirit and scope. Furthermore, all examples recited herein are principally intended

expressly to be for pedagogical purposes to aid the reader in understanding the principles of the
present subject matter and the concepts contributed by the inventor(s) to furthering the art and are

The novel features which are believed to be characteristic of the present subject matter, both as to
its organization and method of operation, together with further objects and advantages will be
better understood from the following description when considered in connection with the
accompanying figures.
Although embodiments for the present subject matter have been described in language specific to
package features, it is to be understood that the present subject matter is not necessarily limited to

embodiments for the present subject matter. Numerous modifications and adaptations of the
system/device of the present invention will be apparent to those skilled in the art, and thus it is

the scope of the present subject matter.
It will be understood by those within the art that, in general, terms used herein, and especially in
the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms
(e.g., the term “including” should be interpreted as “including but not limited to,” the term
“having” should be interpreted as “having at least,” the term “includes” should be interpreted as
“includes but is not limited to,” etc.). It will be further understood by those within the art that if a
specific number of an introduced claim recitation is intended, such an intent will be explicitly
recited in the claim, and in the absence of such recitation no such intent is present. For example,
as an aid to understanding, the following appended claims may contain usage of the introductory
phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such
phrases should not be construed to imply that the introduction of a claim recitation by the indefinite
articles “a” or “an” limits any particular claim containing such introduced claim recitation to
inventions containing only one such recitation, even when the same claim includes the introductory
phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or
“an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true
for the use of definite articles used to introduce claim recitations. In addition, even if a specific
number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize

that such recitation should typically be interpreted to mean at least the recited number (e.g., the
bare recitation of “two recitations,” without other modifiers, typically means at least two
recitations, or two or more recitations). Furthermore, in those instances where a convention
analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended
in the sense one having skill in the art would understand the convention (e.g., “a system having at
least one of A, B, and C” would include but not be limited to systems that have A alone, B alone,
C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in
general such a construction is intended in the sense one having skill in the art would understand
the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited
to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C
together, and/or A, B, and C together, etc.). It will be further understood by those within the art
that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether
in the description, claims, or drawings, should be understood to contemplate the possibilities of
including one of the terms, either of the terms, or both terms. For example, the phrase “A or B”
will be understood to include the possibilities of “A” or “B” or “A and B.”
It will be further appreciated that functions or structures of a plurality of components or steps ma y
be combined into a single component or step, or the functions or structures of one-step or
component may be split among plural steps or components. The present invention contemplates
all of these combinations. Unless stated otherwise, dimensions and geometries of the various
structures depicted herein are not intended to be restrictive of the invention, and other dimensions
or geometries are possible. In addition, while a feature of the present invention may have been
described in the context of only one of the illustrated embodiments, such feature may be combined
with one or more other features of other embodiments, for any given application. It will also be
appreciated from the above that the fabrication of the unique structures herein and the operation
thereof also constitute methods in accordance with the present invention. The present invention
also encompasses intermediate and end products resulting from the practice of the methods herein.
The use of “comprising” or “including” also contemplates embodiments that “consist essentially
of” or “consist of” the recited feature.
