The Problems Our Project Have Potentially To Fight These
Problem
World Thirst For Energy Which Is Always Increasing
Dependency On Conventional Energy Which Is Just Too Much
Global Warming
Wasting Up Of Resources
Limitation Of Non Conventional Energy
World Energy Thirst EIA's recently released International Energy Outlook 2013
(IEO2013) projects that world energy consumption will grow by 56% between 2010 and 2040, from 524 quadrillion British thermal units (Btu) to 820 quadrillion Btu. Most of this growth will come from non-OECD (non-Organization for Economic Cooperation and Development) countries, where demand is driven by strong economic growth.
Renewable energy and nuclear power are the world's fastest-growing energy sources, each increasing 2.5% per year. However, fossil fuels continue to supply nearly 80% of world energy use through 2040. Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coal bed methane increase.
Based on current policies and regulations governing fossil fuel use, global energy-related carbon dioxide emissions are projected to rise to 45 billion metric tons in 2040, a 46% increase from 2010. Economic growth in developing nations, fueled by a continued reliance on fossil fuels, accounts for most of the emissions increases.
The Global Warming
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect
Effects Of Global Warming
Cause Of Global Warming Burning of fossil fuels (Coal/Crude oil)
Power plants generate electricity
Transportation-----fuels for transports (E.g. LPG, kerosene, fuel oil)
Industrial processes (E.g. manufacture of cement, steel, aluminum)
Other greenhouse gases emission Agriculture Forestry Other land uses Waste management
Besides carbon dioxide, other
gases such as methane,
chlorofluorocarbons, nitrogen
oxides and ozone also
contribute to the greenhouse
effect.
Example : Using natural gas to cook CH4 + 2O2 CO2 + 2H2O
How Serious The Problem Is?
increased about 0.6°C/century since the late19th century increased to 2°C/century over the past 25 years Regions that have temperatures (1-3°C) warmer than the
average: United States Most of the Europe
Regions that have temperatures (1-3°C) cooler than the average: Australia
The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment.
Direct Temperature Effects
Increase in average temperature
More extreme heat waves during the summer; Less extreme cold spells during the winter
Harmful to those with heart problems, asthma, the elderly, the very young and the homeless
Extreme Events Extreme Events: Heat waves; Cold waves; Storms;
Floods and Droughts Global warming
An increase in the frequency of extreme events
More event-related deaths, injuries, infectious diseases, and stress-related disorders
Climate-sensitive diseases Increase the risk of some infectious
diseases [particularly that appear in warm areas; are spread by
mosquitoes and other insects] E.g. Malaria, dengue fever, yellow fever, encephalitis
Algal blooms occur more frequently as temperatures warm (particularly in areas with polluted waters)
Diseases (e.g. cholera) accompanying algal blooms become more frequent
Air QualityAn increase in the concentration
of ground-level ozone
Damage lung tissue
Harmful for those with asthma and other chronic lung diseases
Food supply
Rising temperatures and variable precipitation
Decrease the production of staple foods in many of the poorest
regions
Increasing risks of malnutrition
Population displacementRising sea levels
Increase the risk of coastal flooding
(Necessitate population displacement)
More than half of the world's population now lives within 60km of the sea.
Most vulnerable regions: Nile delta in Egypt, the Ganges-Brahmaputra delta in Bangladesh, many small islands, such as the Maldives, the Marshall Islands and Tuvalu.
UV Exposure (Australia)
Skin Cancer an abnormal growth of skin tissues.
Premature aging make the skin thick, wrinkled, and leathery
Cataracts No longer have transparent lenses in their
eyes
UV Exposure (Australia) Other Eye Damages
Skin cancer around the eyes Degeneration of the yellow spot
Suppression of Immunity Overexposure to UV radiation suppress
proper functioning of the body's immune system and natural defenses of skin
UV-B radiation weakens the immune system increases the chance of infection and disease
Non Conventional Energy
Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.
Limitation Current availability of fuel obtained from plants that can be used
as economical energy practically is limited. Though lot of research and development activities is going on around to world to develop plants that could provides suitable fuels economically and in sufficient quantities.
The total potential of renewable energy source as wind power and tidal power is limited.
The current capital cost for equipment to convert renewable energy such as solar, wing and tide is very high.
Plant for generating power from wind, and tides can be located only in places where suitable conditions of tide or wind exist.
The plant for generating energy from sun light, wind and solar energy have to be spread around large areas.
Solar power is dependent on availability of sunlight. Thus the availability of power fluctuates from zero to maximum every day.
There have been some allegations that large scale use of wind power can interfere pattern of wind flow and disturb the set weather pattern. Use of hydro power is already known change the pattern of silting in rivers.
Solar energy disadvantages: solar radiation is depending on geographical location solar radiation is depending on the cycle day/night capture of solar radiation is requiring a large amount of necessary materials Wind energy disadvantages: wind turbines are noisy and can become dangerous for wild birds Hydroelectric energy disadvantages: affects ecology by the process of vegetation decaying, which is releasing
methane, which is also responsible with the greenhouse effects flooding is another problem caused by the dam releasing; Geothermal energy disadvantages: geothermal wells drilling is costly together with the heat, poisonous gasses could be released
How Our Project Can Help ?
How Much Do We Walk In Our Life Span?
The average moderately active person take around 7,500 step/day. If you maintain that daily average and live until 80 years of age, you’ll have walked about 216,262,500 steps in your lifetime.
Doing the math; the average person with the average stride living until 80 will walk a distance of around 110,000 miles.
Which is the equivalent of walking about 5 times around the Earth, right on the equator.
Electricity generating Footwear
While looking for our project we first thought of tidal energy which had a large scope in the coming decade but not every country have sea connection. So it was not possible and a solution in this case is something which satisfy every country to make a bigger change. And while looking for a solution we came the Piezo Electric Effect. First we thought the idea cannot produced such a major but after some calculation it was literally mind blowing results. The concept of making shoes that produce electricity may seem but odd but the amount of electricity that can be saved from the it is massive.
Don’t believe this is revolutionary? After this calculation you will also believe.
The typical cell phone battery voltage is around 3 to 4Vdc. Also, the battery is rated in mAh which is a measure of battery capacity (milliamp * hours). If I remember correctly a decent phone battery is around 2000-3000mAh. This means that if I connect a load to this battery which draws 2000-3000mA, the battery will roughly survive for about an hour. Theoretically.
Assume that your new smart phone has the following specifications....
3.5V battery 3000mAH battery capacity Requires a full recharge everyday.
Therefore the battery lasts 24hours, which correlates directly to the AVERAGE current draw on the battery: I = 3000mAH / 24H = 125mA
Knowing that your battery is 3.5V, finding the AVERAGE power consumption is just
Power = V * I = 3.5 * .125 = .4375W So, Around 6, 57, 29, 50,124+ mobile phone users. As we speak this number is increasing at a very fast rate. Each mobile consume around .5W So everyday total consumption is = 5*6, 57, 29, 50,124 = 32,86,47,50,620 W
And if we add other small appliance like mp3 player, watches, wireless joy-pad and gaming console, power bank, GPS devices, wireless speaker ,etc. this will easily become around 50,00,00,00,000 W. Around 5,00,00,000 KW( 50 million kilowatt).Assuming this to be done in one day(24 hours *150 days as the rest of the time we will not be walking or doing any kind of work) then it will be 8 640 000 000 000 Kilowatt hour [kWh]= 8 640 Terawatt hour [TWh]. It is equal to 2 times the total production of USA electricity power and 7 times that of India . This energy is 100% natural and is independent of external factors like sunlight, wind, etc. So this can be a new step towards a bright energy rich future.
This is equal to 994800000 kg CO2e which is equivalent to 271580400 kg of Carbon which we can save from entering the atmosphere daily. And this could contribute a lot in fighting global warming.
Concept Behind the Project
Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and piezo, which is Greek for “push”.
One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect (the generation of electricity when stress is applied) also exhibit the converse piezoelectric effect (the generation of stress when an electric field is applied).
When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centers in the material takes place, which then results in an external electrical field. When reversed, an outer electrical field either stretches or compresses the piezoelectric material.
Why Not Use Dynamos?
As much as possible, we tried to avoid using dynamos. Yes dynamos produce more electricity but it will feel like you've stuffed a rock in your shoe. Don't forget dynamos will create a lot of noise.
