Simple???


Yes??

it is all about “Thermo” and “Dynamics”. The
word “thermodynamics” stems from the Greek words
“therme” (heat) and “dynamis”(power).


No??

Today the same name is broadly interpreted to
include all aspects of energy, energy transformations
and properties of a substance.


Thermodynamics is both a branch of physics and an
engineering science, and is closely related to the
science of heat and mass transfer, fluid dynamics, and
mechanical, chemical, civil and electrical engineering.

What is “Thermodynamics” ?

Example 2: Tidal Stream Turbine

SeaGen

is the world's first large scale commercial tidal stream generator. It is four
times more powerful than any other tidal stream generator in the world.


Reference: http://en.wikipedia.org/wiki/SeaGen

Tidal power is the only form of energy which
derives directly from the relative motions of
the Earth
-
Moon system. Tidal power is
practically inexhaustible and classified as a
renewable energy source. Tidal energy is
periodical and predictable. In contrast, wind
and solar energies cannot be well
-
predicted.

“15 April, 1988 the aircraft performed its maiden flight using
liquid hydrogen
.
Upon flight testing and development 18 January, 1989 TU
-
155 a/c performed
its first flight on
liquefied natural gas
. Large flight testing Program was fulfilled,
several international flight demonstrations were made including those to
Bratislava (Czhekoslovakia), Nice (France), Berlin and Ganover (Germany).”
