SAVING THE EARTH FROM CLIMATE CHANGE AND POWER CRISIS
I want to reach to the World for SAVING THE EARTH FROM CLIMATE CHANGE AND POWER CRISIS
Considering the making of a green house, effects of heat on fluids and heat transmission methods, gases can’t make a green house and so they can’t make green house effect No relationship between gases and climate change. Pollutants, gases and air all absorb heat from the sun before it reaches the Earth. Cloudy misty foggy murky smoggy hazy days are colder. Gases by convection methods of heat transmission cool the earth. Colder during night and coldest before daybreak Cyclones hurricanes tornadoes are cooling systems as emergency. No gas can be defined as green house gas.
CAUSES- Man disturbed mechanism of cooling system- the rain cycle by
Urbanization- drainage system pavements houses roads stopped evaporation.
Deforestation- Reduced evaporation drastically.
Deserted land deserts- No evaporation at all.
Rain means colder clean atmosphere. Recharging ground. Spreading water all over the world. Easy access of drinking water. Proper irrigation. Rich vegetation. Snow on poles and mountains thus lower sea water level.
Simple logic take water back to places where it came from. Rain cycle needs lot of evaporation of water from the surfaces of the Earth
SOLUTION- Boosting evaporation by scattering water on the surfaces of the Earth not sparing even the deserted lands and deserts. Water can be drained from higher to lower places. Now it is an easy task for mankind. Use discharged water from the hydropower installations. Develop network of water delivery system as culture. Harness unlimited hydropower from water delivered through pipes. Considering fluid properties of water and nature of the gravitational force of the earth many turbines can be installed in series without breaking water column Conventional methods of installing turbines don’t consider those aspects. Turbines don’t reduce the power of running water

piezo power
The world is facing energy crisis greedy man has tapped all the non renewable sources.
“The blue planet is losing its charm
As it is getting warm
It’s now time to act
Or the earth won’t last
It’s funny we fight for caste
For soon the earth won’t last”

Advantages:
In Pondicherry I have heard
On December 26, 2004, when towering waves of the 2004 Indian Ocean earthquake crashed against India's south-eastern coastline killing thousands, the former French colonial enclave of Pondicherry (now puducherry) escaped unscathed. During the city's nearly three centuries as a French colony, French engineers had constructed and maintained a massive stone seawall, which kept Pondicherry's historic center dry even though tsunami waves drove water 24 feet above the normal high-tide mark.
The barrier was initially completed in 1735. Over the years, the French continued to fortify the wall, piling huge boulders along its 1.25-mile (2-kilometer) coastline to stop erosion from the waves pounding the harbour. At its highest, the barrier running along the water's edge reaches about 27 feet above sea level. The boulders, some weighing up to a ton, are weathered black and brown. The sea wall is inspected every year. Whenever gaps appear or the stones sink into the sand, the government adds more boulders to keep it strong.
The Union Territory of Pondicherry recorded some 600 deaths from the huge tsunami waves that struck India's coast after the mammoth underwater earthquake off Indonesia, but most of those killed were fishermen who lived in villages beyond the artificial barrier. This is one advantage think of the power we get due this as soon as the power is got it will be sent to the power station to be used here and the we can have gates for fishermen to move we can avoid the beaches as people need it for enjoyment. This idea can be utilized in buoys where it is used for its lighting. We can use this in to increase to power production by attaching a series of piezo crystals on the river facing side, on the turbines for increase in power production.
Peizo power (abstract)
Advantages of my energy source:
Non polluting green, produces high power, not noisy, The sea wall helps to prevent tsunami hurricanes and etc, The power is renewable, easy to get
Some may say the pezio crystals will break easily for that too there is a solution we attach thick foam or a polymer which is flexible, water resistant solves the problem.

CALCULATIONS
In a 1cm³quartz crystal 1hen 1 Newton is applied it produces 6.25v
So the acceleration of wave=4m/s²(15-4/3)
Total mass=3kg as minimum 3l of water hit the crystal
Force applied=12N
and 10 crystal the voltage produced=10×12×6.25×10=7500v for 1 sec
we have 200 such rows as the wall is at least be 2m value and we have 100 columns as wall is 1m long=20000×7500
but waves take some 5sec to reach the shore so value=30000000v
the velocity is to high so we attach foam which reduces it by half
value=30000000v
power produced=v²/r (r= 2000×200×100)
=5 MEGAWATT AND THIS FOR 2SEC IMAGINE EVEN IF WE REDUCE IT 5 TIMES TO ENSURE SAFTEY OF CRYSTAL OR IF SEA WAVE ACCELERATION DECREASE (BUT IT NEVER DECREASES BEYOND 3M/S²) IT IS STILL HIGH.
Total cost
Total cost of a wall for a metre=2000Rs
Cost of a crystal=50rs
Total cost=50×20000
=1000000+2000+5000(misc charge)
=1007000Rs
But in bulk it is cheap but still it offers
