Importance of nano technology
Many new technologies today possess some sort
of nano technological device in their system.
Things we take for granted todaycellular phones,
handheld computers, mp3 players were notimagined 10 or 20 years ago.

HISTORY
From the day to day life the use of nano particles are
increasing.
But by using these nano particles the power can be
generated?
HOUSTON (Nov. 19, 2012) Rice University
scientists have unveiled a revolutionary new
technology that uses nanoparticles to convert solarenergy directly into steam. The new solar steam
method from Rices Laboratory for Nanophotonics
(LANP) is so effective it can even produce steam
from icy cold water.

BRIEF HISTORY
Figure 1.9: Tokyo Science
University.
Birth of Nanotechnology
Professor Taniguchi of Tokyo Science
University used the word
nanotechnology to describe the scienceand technology of processing or building
parts with nanometric tolerances.
A nanometer is a unit of length in the
metric system, equal to one billionth of
a meter.

OPERATION The efficiency of solar steam is due to the light-
capturing nanoparticles that convert sunlight into
heat. When submerged in water and exposed to
sunlight, the particles heat up so quickly they
instantly vaporize water and create steam.
With this technology, we are beginning to think
about solar thermal power in a completely differentway.

How it can be employed?
It is employed in the sea. The following waves lift thefloating structure that is connected to the diaphragm
pump, which in turns lifts the sea water into higher
levels. The water flows down due to gravity spins the
turbine and produce electricity.
Coming out of turbine, the water falls into a glass
storage container filled with carbon nano particles which
quickly Evaporates water when exposed to the sun by
direct sun light or using reflectors

Once the container is full, further water entry is
blocked using a valve. The excess water is released into
the sea.
The vapours are captured through a pipe to generate
distilled water for human consumption (Or) by using that
steam it can be sent to steam turbine. The steam turbine
rotates by the connection to the generator electrical
energy is produced as output.

conclusionWe can conclude that using this method, we
can
generate conventional and eco-friendlyelectricity using wave power and turbine.
water can be desalinated to produce lowcost, safe drinking water from the sea
water using solar power
