INTRODUCTION Background Today’s population consumes enormous amounts of energy. Even with the new energy efficient products that are available on today’s market, Stats Canada claims that Canada’s energy demand continues to rise each year. This energy demand growth could be attributed to many causes such as: population growth, dependence on technology, development in under developed world countries. One new alternative energy source that is not getting as much recognition as it should is piezoelectricity. The concept behind piezoelectricity will be examined at a greater length later on in this report. Basically the main concept behind piezoelectricity is compressing a piezo ceramic which will in turn produce a static voltage which we could …show more content…
Although solar seems to be excluded from most of the disadvantages listed above tied to using renewable energy sources, it still has two big main disadvantages. The first being that, it is impossible to shut off. The fact that there is no way to shut these solar panels off makes them prone to catch fire. This is harmful to the place they are located. It is especially bad when people put them on their roofs which can cause house fires. Another big issue with solar is that it takes a lot of room for the amount of energy that it produces. According to the U.S. Energy Information Association to produce 1 MW of solar energy, assuming that your panels are located in price sunny locations, it takes 7.4 acres of solar panels. When you compare it to the nuclear reactors that produce on average 770MW for approximately 500 acres of land. To produce the same amount of energy as one single nuclear reactor you would need approximately 5698 acres of land which is 11 times the amount of space that nuclear …show more content…
Scope In this report you will find a suggestion as to which type of piezoelectric ceramic would be best suited to utilize at Northern College. You will also find calculations outlining how much energy would be available for Northern College to use if they were to install piezoelectric generators within the entrance of the technology hallway. I will provide my recommendation as to whether it would be feasible or not to have the piezoelectric generators installed. Finally, I will prove my theories by building a small piezoelectric generator. Sources The primary sources I will be utilising for this project are alternative energy text books, lectures from the alternative energy course I took last semester with Brian Nankervis and the physics behind transforming the kinetic energy used to compress the piezoelectric elements into usable energy. I will also be consulting with my technical advisor, Derryk Morrish, who has extensive knowledge in electronics. I will also be using the APC PiezoCalc app, on my apple I-Phone, to verify my calculations. I am also using the internet for research on statistics that have to do with the current energy supply problems we
In 1955, her 34-year career included developing and implementing computer code that analyzed alternative power technologies, supported the Centaur high-energy upper rocket stage, determined solar, wind and energy projects, identified energy conversion systems and alternative systems to solve energy problems. Her energy assignments included studies to determine the life use of storage batteries, such as those used in electric utility vehicles. Her computer applications have been used to identify energy conversion systems that offer the improvement over commercially available technologies.

A transducer is a mechanism that changes one form of energy to another form. A toaster is a transducer that turns electricity into heat; a loudspeaker is a transducer that changes electricity into sound. Likewise, an ultrasound transducer changes electricity voltage into ultrasound waves, and vice versa. This is possible because of the principle of piezoelectricity, which states that some materials (ceramics, quartz, and others) produce a voltage when deformed by an applied pressure. Conversely, piezoelectricity also results in production of a pressure whe...
Today our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed. One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need of energy in today’s current world, exploring different ways of producing power are necessary. The differences and similarities of nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production.
Although the world may never be able to fulfill all of its energy needs through renewable energy sources, it is a goal worth trying to achieve. And people are working toward that goal. Many advances in the field of wind generated power have been made in recent years, and research efforts continue to press forward on numerous other alternative energy fronts.
The N Power Peg is a device that was developed to be utilized as a source of energy deriving from the kinetic energy concept. The inventor, impetus behind the innovation and the potential success of this product is further emphasized in this paper.
A Piezo-electric substance is one that produces an electric charge when a mechanical stress is applied. In a Piezo-electric accelerometer a mass is attached to a Piezo electric crystal which is in turn mounted to the case of the accelerometer. When the body of the accelerometer is subjected to vibration the mass mounted on the crystal wants to stay still in space due to inertia and so compresses and stretches the piezo electric crystal. This force causes a charge to be generated and due to Newton law (F=ma) this force is in turn proportional to acceleration. The charge output is converted to voltage output by the use of integral electronics (for example: in an IEPE accelerometer) or made available as a charge output (pc /g) in a charge output Piezo electric
Some climate scientists such as Ken Caldeira believe that humans will never reduce greenhouse gas emissions and that the earth will eventually return to the climate of the Cretaceous period due to climate change (How Far Can Climate Change Go?, 2012). There is enough evidence to suggest that this will not happen. Thanks to our individual senses of environmental consciousness, our uses and further research of alternative energy sources and fuels, and the potential for space colonization and exploration. We still have a chance to reverse our impact on the planet because of further advancements in technology and a sense of global consciousness.
In this electronics science fair project, you will build and test your own life-size robot grasshopper! It demonstrates how energy can be turned into different forms. First, radiant energy, which comes from the Sun or from a lightbulb, is turned into electrical energy by a small solar panel. A solar panel (solar means of or relating to the Sun) is a panel that produces either electricity or heat when light shines on it.The electrical energy from the solar panel is then used to make a small motor spin. In other words, the electrical energy is converted into kinetic energy. Kinetic energy is defined as the energy of motion. The motor has a small weight on it, which is unbalanced, so when the motor is turned on, the unbalanced weight moves, making
With a looming energy crisis and an unstoppable rapid decrease in fossil fuels, the need for renewable energy is greater than ever. Yet it is inevitable that with every new solution, there are consequences. People can only hope that the energy crisis will be resolved with every new and advanced generation of scientists.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
On average, one person will walk about 150 million steps in their lifetime (Phillips). What if these footsteps could actually be harnessed and converted to a form of energy that could actually help power the world? The very notion seems to come straight out of a science fiction novel about a utopian society. However, one man has taken the steps to make this dream a reality. Laurence Kemball-Cook has developed a product called Pavegen; essentially, it is a rubber tile that can, “harvest kinetic energy from the impact of people stepping on them” (Jain). By harnessing energy generated from footsteps, Pavegen can help to power appliances such as cellphones and streetlights. The idea behind Pavegen is to develop an accessible product that can help lower economic bills, and to make a positive impact environmentally. If similar products were produced around the world, Pavegen tiles could help businesses in taking one step closer to building a sustainable and environmentally whole planet Earth.
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Finding use in “spacecrafts, pacemakers, underwater systems, electric automobiles, and remote monitoring systems” (source 6), the atomic battery has existed for over a century and is growing to benefit our world. The atomic battery generates electricity from a nuclear reaction, utilizing the radioactive decay of specific elements. The atomic battery is certainly not meant for households or as a source of common battery use, but rather powerful equipment needing to run for long, extended periods. Atomic batteries are quite expensive, but can provide an immense amount of energy that will conduct over an extremely long life period. This paper will explain the basic functioning of an atomic battery, investigate a brief history of the atomic battery, and also examine one aspect of energy conversion within atomic batteries, thermal converters.
My next step was solar energy investigation. The thought of a panel of treated glass exposed to the sun, with no other work involved, pumping out usable electricity was overwhelming. What a gold mine this was. No air pollution was being produced and there were no moving parts to brake. Later I learned that there were a few more variables to this energy production system, costly variables, such as inverters to transform and condition the electricity and battery banks to store it.
