Anywhere there is an industrial process that
involves transforming raw materials into products-streel mills, paper plants,
refiners, chemical plants, oil and gas pipelines and general manufacturing-heat
is wasted as a by product,. Waste Heat 
is a by product of industrial processes that is released through
mechanicalequipments. If not captured and used to generate emission free
renewable – equivalent power, waste heat is released through stocks, vents,
flares and mechanical equipment. Waste heat to power (WHP) works by capturing
waste heat w/ recovery unit and converting it to electricity through a process
called heat exchange.WPH systems use the same technologies
deployed in a number of industries including the geothermal industry. Main
technologies used by WPH  developers are
Stream Turbine Tech. , Organic Rankine Cycle, Supercritical (02, Kalina Cycle).
Stiring Engine, and emerging technologies such as thermoelectrics. Thermoelectrics
are solid-state semiconductor that capitalize on a difference to turn heat into
electricity w/ few or no moving parts. According to an EPA report, there is
between 7 and 10 gigawatts of waste heat to powercapacity in US, enough to power 7 to 10 million
American homes

In recent years, global warming and limitations in
use of energy resources increase environmental issues of emissions.Also in
industry,most of the expenses are due to energy (both electrical and thermal),
labor and materials.But out of them, energy would relate to the manageability
of the cost of potential cost saving and thus energy management will help in
cost reduction. The possibilities
of thermoeclectric system contribution to 
“green ”  technologies
specifically for waste heat recovery from industry fuel gases. It results into
extensive research on green technologies producing electricity.Waste heat
recovering techniques, such as 
thermoelectric generator (TEG) developed.. thermoelectric generator
direct converts waste-heat energy into electric power where it is unnecessary
to consider the cost of thermal energy input.The application of this technology
can also improve the over all efficiency of the energy conversion system.

A  thermoelectric generator is a semiconductor
device that transforms the heat difference between its two layers into
electricity, it is also devices that convert temperature differences into
electrical energy, using a phenomenon called the “Seebeck Effect”. The seebeck
effect involves a temperature differential across the module by heating one side
of the module and cooling the opposite. A great misconception of how
Thermoelectric Generators work is that They
simply convert heat sources to electricity. Thermoelectric generators work on
temperature differences. Some Thermoelectric Generator, can generate power when
the potential temperature differential reverse polarity.

         Battery storage technologies seem to
be the hot topic wherever you look in energy industry. Battery storage is a
type of battery that can be given a new charge by passing an electric current
through it. Some basic concepts about battery storage cell are capacity,
voltage, current and energy. The more electrode material contained in the cell
the greater its capacity. Voltage is the potential. The voltage between two
points is equal to the work done per unit of charge against a static electric
field to move the test charge gainst a static electric field to move the test
charge between two points.  Property
maintained inchargable batteries can provide good service and long life.
Maintenance involves regular monitoring of battery voltage. Rechargable
batteries comprise a reference LED, LED ref , which operates at a constant
current of 1 MA and provides reference light constant intensity regardless of
battery voltage. The light output of the variable LED changes with respect to
changes in battery voltage. The side-by-side mounted LEDs let you easily can
paste light intensities and, thus, battery-stanes.

measured in amperes or amps (A) is the rate of electric flow which, if
maintained in two straight parallel conductors of infinite length, of
negligible circular cross-section, and placed one meter apart in vacuum, would
produce between these conductors a force equal to 2×10?7 newton per meter of
length. Energy, measured in watt-hours (WH) or joules (J), is a measure of the
amount of work, or change, that can achieved. One watt-hour is equivalent to
3,600  joules. Power vs. Energy: The
terms “power” and “energy” are frequently confused. Power
is the rate at which energy is generated or consumed and hence is measured in
units (e.g. watts) that represent energy per unit time.
