Thermodynamics is a branch of physics concerned with Heat & Work

History of thermodynamics

Reason for thermodynamics: #PoliticalEconomy http://goo.gl/0dVsT  of 19 Century & quest for fuel efficiency:

The above is also known as “Engineering thermodynamics”.

There is also the “Chemical Thermodynamics”:

Thermodynamics is concerned with interactions between  systems:

Thermodynamics is concerned with the “before” & “after” of a process:

There are three laws in thermodynamics each covering a specific property:

“Solar Power”, “Solar Energy” & “Solar Panel” all are  sales gimmick for manufactured Photovoltaic cell units using fossil fuels

What is a Photovoltaic cell (commonly and wrongly referred to as solar panels”)

A photovoltaic cell (PV cell) is a specialized semiconductor diode that changes visible light into direct current (DC). Some PV cells can also change infrared (IR) or ultraviolet (UV) radiation into the unidirectional flow of electric charge (DC current)

working of photovoltaic cell (PV cell) relies on Heat (thermal Energy) Transfer & Radiation

Heat (thermal energy) Transfer is an important science in engineering

Any viable system for electric power generation has to satisfy four conditions:

4 condition for Power gneration.jpg

Using manufactured photovoltaic cell (PV cell) (manufacturing process uses fossil fuels) fails all four conditions stated above.

Photovoltaic cell (PV cell) manufacturing processes wholly & solely depends on fossil fuel http://goo.gl/DkEeIC

Processes used in production of Photovoltaic cell (wrongly referred to as solar panels) are wholly & solely dependent on using fossil fuels, & have hazardous toxic by-products which have to be disposed of safely.

A company like Qatar Solar Technologies (QSTec) can produce 8,000 tonnes per annum Polysilicon for export to the world disguised under false banner of renewable energy using processes listed below which use fossil fuels

Processes used for manufacturing Photovoltaic cell (PV cell) are:

Electric Power

We don’t use Electricity we use Generated Electric Power

What is electricity?

Electricity  means:

The physical phenomena arising from the behaviour of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge.

The physical science of such phenomena is also called electricity

Electricity is not generated it is there in nature no doubt electricity has a role in life like all other physical phenomena.

When 2 coulombs of positive electricity cross a system boundary at a point “A” & re-enter the system at a point “B”, the electric potential of “A” being v volts above the potential of “B”, the system does positive work on its surroundings equal to 2v joules.

The statement above is the definition of the volt in a form acceptable to thermodynamicists. The coulomb is a unit of electric charge, which is defined in any available texts on electricity.

Further, one coulomb per second is called a current of one ampere. Consequently when a steady current of I amperes flows between the points A and B of the above definition the system does work at the rate of 1V joules per second.

Electrical effects were known in ancient times, but the starting point of modern knowledge and USE of electricity may be said to be the discovery by Volta in 1799 of the possibility of producing an electrical current from a chemical reaction, namely that between paired discs of copper and zinc in brine as shown below:

Volta’s pile

Although developments of it are used for car accumulators and the batteries of flash lamps, Volta’s discovery has not yet led to any large-scale production of electrical power; the reason is that, on the one hand, the substances with which it is easy to produce electrical power are expensive, while on the other hand the chemical reactions undergone by common fuels are difficult to harness in this way, for technical reasons. Nevertheless the possibility is of great theoretical interest.

Modern use of the Electric Power Generation derives from Faraday’s discovery, in 1831, of how electric power is generated by moving an electrical conductor across a magnetic field (see sketch below), thus eventually making possible the convenient transmission of power. Hence the name Power Station & Power Line.

Dynamos & electric motors should therefore be thought of, not as prime movers, but as modern equivalents of the levers, gears, belts and pulleys which have been used for transmission since engineering began.
