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” In this poem I have clearly said all our problems all renewable energy is before our eyes but we close our eyes for all the petty problems in the society .Coming to the topic waves are huge quantities of energy they strike the obstacles with high velocity but we waste this energy many other countries tap this energy often inside the ocean one day I came across this idea .I just learnt about piezo electric effect and I thought if we build a sea wall with piezo crystals in the shore very near the sea the waves will constantly hit the wall but the hard concrete wall will not give in and the crystals should have high density .They will be attached with piezo electric materials and such that the outer layer of the wall will be embedded with them. later I tried to learn more on this in such way ”I heard In 2007, two MIT graduate students proposed the idea of installing piezoelectric flooring in urban areas. Dubbed "Crowd Farming," the idea was to install a flooring system that would take advantage of piezoelectric principles by harvesting power from footsteps in crowded places such as train stations, malls, concerts and anywhere where large groups of people move. The key is the crowd: One footstep can only provide enough electrical current to Curved or stepped seawalls are designed to enable waves to break and to dissipate wave enlight two 60-watt bulbs for one second, but the greater the number of people walking across the piezoelectric floor, the greater amounts of power produced. It's not beyond the realm of possibility -- approximately 28,500 footsteps generate energy to power a train for one second [source: Christian Science Monitor]”. Imagine how much power will big waves constantly hitting the hard wall produce. This wall will cost about 300rs per metre.with the quartz crystal costs 216 for 36 pieces each 2 inches approximately .A range of seawall types can be envisaged in relation to wave energy, resembling cliff and beach profiles. Vertical seawalls are built in particularly exposed situations. These reflect wave energy and under storm conditions standing waves will develop. In some cases piles are placed in front of the wall to lessen wave energy slightly.ergy and repel waves back to the sea. The curve can also prevent the wave over topping the wall, and provide additional protection for the toe of the wall. A series of rubble mound-type structures (revetments, riprap) are used in less demanding settings. The least exposed sites involve the lowest-cost bulkheads, or revetments of sand bags or geotextiles. These serve to armour the shore and minimize erosion. They may be either watertight, covering the slope completely, or porous, to allow water to filter through after the wave energy has been dissipated. 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. By r.vignesh 9k Psbb kk. Nagar Chennai-78 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
