3. Words of Tesla "It is not a dream, it is a simple feat of
scientific electrical engineering, only expensive -- blind,
faint-hearted, doubting world! [...] Humanity is not yet
sufficiently advanced to be willingly led by the discoverer's keen
searching sense. But who knows? Perhaps it is better in this
present world of ours that a revolutionary idea or invention
instead of being helped and patted, be hampered and ill-treated in
its adolescence -- by want of means, by selfish interest, pedantry,
stupidity and ignorance; that it be attacked and stifled; that it
pass through bitter trials and tribulations, through the strife of
commercial existence. So do we get our light. So all that was great
in the past was ridiculed, condemned, combatted, suppressed -- only
to
4. BuildingIntegrated Photovoltaic's(BIP) Building-integrated
photovoltaics (BIPV) are photovoltaic materials that are used to
replace conventional building materials in parts of the building
envelope such as the roof, skylights, or facades. The advantage of
integrated photovoltaics over more common non-integrated systems is
that the initial cost can be offset by reducing the amount spent on
building materials and labor that would normally be used to
construct the part of the building that the BIPV modules replace.
These advantages make BIPV one of the fastest growing segments of
the photovoltaic industry.
5. PiezoelectricGenerators Piezoelectricity is the electric
charge that accumulates in certain solid materials (such as
crystals, certain ceramics, and biological matter such as bone, DNA
and various proteins) in response to applied mechanical stress. The
word piezoelectricity means electricity resulting from pressure.
The piezoelectric effect is understood as the linear
electromechanical interaction between the mechanical and the
electrical state in crystalline materials with no inversion
symmetry. The piezoelectric effect is a reversible process in that
materials exhibiting the direct piezoelectric effect the internal
generation of electrical charge resulting from an applied
mechanical force also exhibit the reverse piezoelectric effect the
internal generation of a mechanical strain resulting from an
applied electrical field.
6. Ocean thermal Energy Ocean thermal energy conversion (OTEC)
uses the temperature difference between cooler deep and warmer
shallow or surface ocean waters to run a heat engine and produce
useful work, usually in the form of electricity. OTEC is a base
load electricity generation system, i.e. 24hrs/day all year long.
However, the temperature differential is small and this impacts the
economic feasibility of ocean thermal energy for electricity
generation. These fluids have low boiling points, and are therefore
suitable for powering the systems generator to generate
electricity. The most commonly used heat cycle for OTEC to date is
the Rankine cycle using a low-pressure turbine. Open-cycle engines
use vapour from the seawater itself as the working fluid.
7. Tidal Energy Tidal power is taken from the Earth's oceanic
tides, tidal forces are periodic variations in gravitational
attraction exerted by celestial bodies. These forces create
corresponding motions or currents in the world's oceans. A tidal
generator converts the energy of tidal flows into electricity.
Greater tidal variation and higher tidal current velocities can
dramatically increase the potential of a site for tidal electricity
generation. Because the Earth's tides are ultimately due to
gravitational interaction with the Moon and Sun and the Earth's
rotation, tidal power is practically inexhaustible and classified
as a renewable energy resource. Movement of tides causes a loss of
mechanical energy in the EarthMoon system: this is a result of
pumping of water through natural restrictions around coastlines and
consequent viscous dissipation at the seabed and in turbulence.
While tidal power will take additional energy from the system, the
effect is negligible and would only be noticed over millions of
years.
8. Geothermal Energy Geothermal energy is heat generated and
stored in the Earth. Thermal energy is the energy that determines
the temperature of matter. The geothermal energy of the Earth's
crust originates from the original formation of the planet (20%)
and from radioactive decay of minerals (80%).The geothermal
gradient, which is the difference in temperature between the core
of the planet and its surface, drives a continuous conduction of
thermal energy in the form of heat from the core to the surface
Geothermal power is cost effective, reliable, sustainable, and
environmentally friendly, but has historically been limited to
areas near tectonic plate boundaries. Geothermal wells release
greenhouse gases trapped deep within the earth, but these emissions
are much lower per energy unit than those of fossil fuels.
9. Vertical Farming Year-round crop production; 1 indoor acre
is equivalent to 4-6 outdoor acres or more, depending upon the crop
(e.g., strawberries: 1 indoor acre = 30 outdoor acres) No
weather-related crop failures due to droughts, floods, pests All VF
food is grown organically: no herbicides, pesticides, or
fertilizers VF virtually eliminates agricultural runoff by
recycling black water VF returns farmland to nature, restoring
ecosystem functions and services VF converts black and gray water
into potable water by collecting the water of evapotranspiration VF
adds energy back to the grid via methane generation from composting
non-edible parts of plants and animals VF dramatically reduces
fossil fuel use (no tractors, plows, shipping.) VF creates new
employment opportunities VF offers the promise of measurable
economic improvement for tropical and
10. Miracle Plant (Hemp) Environmental Benefits of Hemp:
Production of hemp material is considered to be eco friendly
because the hemp production generates some environmental benefits:
Pollution free : Hemp is such as hardly plant that can grow almost
anywhere at any climate; it hardly needs fertilizer, herbicides or
pesticides, so it reduces the pollution to the earth, air and
water; but this is not all. Hemp itself actually cleans up toxins
from the ground, under a process namely phytomerediation. Chemical
pollution can also be significantly reduced if displace cotton with
hemp for clothing, as 50% of the worlds pesticides goes on cotton
fields. Sustainable Agriculture : Not just can be grown without
fertilizer, hemp plant also replenishes soil with nitrogen and
nutrients, increases the topsoil, and restore the health and
fertility of the soil that makes hemp farming becomes a sustainable
agriculture. Erosion control & Carbon Sequestration : Hemp tree
has long roots that firmly hold the soil which help control the
erosion. Due to its fast growth, hemp may also be useful in carbon
sequestration - absorbing carbon from the air and storing it back
into the earth.
11. Industrial Hemp Clean industry: Processing hemp fiber for
paper and cloth does not require chlorine that produces dioxins as
it does with wood or cotton fiber. Paper industry which today
mostly uses wood pulp has now become the 3rd largest polluter.
Switching to hemp fiber will make an immense improvement to our
Earth. Eco Fuel: As biodiesel fuel, hemp fuels emit 80% less carbon
dioxide with almost no sulphur dioxide compared to fossil fuel.
This makes hemp flues do not destroy the ozone layer, generating
less greenhouse gas nor causes acid rain that contribute to global
warming and climate change. Hemp fuel even found to be 10 times
less toxic than salt and as biodegradable as sugar! Water-saving:
Hemp plant helps the water crisis that the Earth is facing now,
because it does not need much water to grow. Compared with other
wood and cotton plantation, hemp requires much less water. Land -
saving: 1 acre of usable hemp fiber is equal to the usable fiber of
4 acres of trees or 2 acres of cotton. Using hemp could save the
land cleared for agriculture means; hemp production could reduce
the deforestation. Durable products: Hemp produces stronger fiber
than most other plants, and can be recycled many more times than
other products can. Therefore hemp products are supporting the
reuse, reduce, recycle of the eco living. Efficient Land Use. Hemp
can yield four times of an average forest can. A hemp crop can be
harvested in ninety days, while trees take around twenty- five
years. Just imagine, once we harvested the forest, it will need
some 25
12. Material Recycling Recycling is a process to change waste
materials into new products to prevent waste of potentially useful
materials, reduce the consumption of fresh raw materials, reduce
energy usage, reduce air pollution and water pollution from
landfilling by reducing the need for "conventional" waste disposal,
and lower greenhouse gas emissions as compared to plastic
production Recyclable materials include many kinds of glass, paper,
metal, plastic, textiles, and electronics. So "recycling" of many
products or materials involves their reuse in producing different
materials (e.g., paperboard) instead.
13. Epilogue Finally we have came to the end of our sojourn
with Renewable Technologies and its implication to End the Energy
Crisis. We have seen different avenues of development and
integration. The main objective is to reduce dependency on Fossil
Fuels and use utterly available renewable resources.
