Viable Energy From Ocean Waves

(a) Purpose of Research To investigate the wave conditions offshore along the South African coast to determine wave heights, intervals, and patterns. These results have demonstrated the power potential of ocean waves and identified sites for offshore power stations. The waves off of the South African coast are the most viable, as they have wave heights of between 2.7m (9ft) and 14.6m (48ft). It is also to assist in the development of my power station design, through research into offshore wave composition, principles, periods and characteristics. (b) Procedures I have used various calculations including the surface pressure of salt water per square meter to calculate the potential power produced by a buoy. These figures have been expressed in Kilowatt Hours, and are then able to be divided by the known consumption of a single USA household in 1 year. A figure of the amount of households that can be supplied by a single generator will then be reached. An approximate power output for a single buoy is between 200 and 300 homes per year (Dependant on wave height) A concept for a maintenance free electrical generator suitable for marine use has been investigated. The design will be made as: ● A working demonstration model capable of producing electricity, which consists of a Rotary Induction Generator, ● a scale model to show the appearance of one such generator & ● A large scale model to show how generators can be congregated to form a power station offshore. (c) Data Utilising the calculations of potential power output and the wave data, the financial viability of the generator has been calculated, in relation to current fossil fuel power stations, down to a cost per Kilowatt. Wave data from international marine monitoring websites that provide real time wave condition graphs, have been tracked by myself daily for over 1 month and recorded to provide a large data resource. This provides wave heights of multiple weather systems as well as averages. Costs have been investigated from Internet sources for electrical integration to the national power grid, as well as the generator manufacture. These are estimates, as the exact specifications of my device cannot be finalised without further prototypical research. (d) Conclusion With conclusions reached by thorough research into wave dynamics, weather patterns and their effects on wave heights, Rotary induction power generation and costs related to multiple power systems, I intend to demonstrate fully to the International Electrical Producers, that coal fired power plants are more costly and environmentally damaging than my revolutionary concept for a truly economically viable, ocean based generator system.

The Usage of Bananan Stem in The Production of Baby's Diapers

In this project, the stem of the banana tree is innovated into the absorbent substance in the baby’s diapers. A water proof material too has been innovated . In the study carried out, several changes has been identified in the production of an environment friendly disposable diapers.The structure of water molecules and cellulose as well as charges in both materials will enable cellulose present in all green plants to absorb water easily and effectively. Cellulose is also insoluble in water or solvent. This project uses the banana stem due to its high cellulose content and furthermore the cellulose present has a very fine structure which will increase its absorbency rate. Baby’s urine will be absorb into the absorbent material through capillary actions due to surface tension that develops between the cellulose and baby’s urine. The absorbent substance in baby’s diapers available today in the market is made up of Polyacrilate (SAP) and cellulose which are extracted from hardwoods, particularly pine trees. The production of the absorbent substance from the cellulose will help to reduce the logging of hardwoods.

CIRCUIT TESTER

The purpose of this project is to create a project that can improve the quality and the production of the merchandise and also to prevent a 100% of mistakes in the electronic components which are complicated to detect or not detectable for us when we are making a circuit. Other of the purpose of this project is to prevent the bad production in the products which are elaborated in a company and then to check if the employee is working well, in that way the company will be able to avoid the bad production and it will be more profit for the company thanks to the products.

Automated Traffic Light

This Project is inspired by the situation incurred by pedestrians, which for the most part are students who need a crossway in order to obtain public transportation or to get to the school; the difficulties that are faced by the personnel to exit the parking lot as well as the students who have a vehicle and to help those parents who drop and pick up their children at the school. At the same time, we would like to reduce the amount of contaminated gas emissions that are emanated into our environment. As consequence of the emission of toxic substances, the air contamination can cause side effects such as the burning of eyes or ears, throat irritation and itching and or respiratory problems. Under determined circumstances, some chemical substances that are found in the contaminated air can produce cancer, congenital malformation, brain damage and disorders to the nervous system, as well as, pulmonary damage and harm to the respiratory tract. For the present investigation it has been suggested as a primary goal: The development of a device, in this case a traffic light, which has the objective to reduce the previously mentioned traffic/security problems that arise upon entering and exiting the institution. The secondary goal is to have a friendly ecological impact within our community. This device was built and tested during a month to obtain figures and demonstrate benefits reported. The device should be low maintenance, it should have a long lifetime and, be simple enough to be operated by those who use it. Among the benefits found, the safety of the students, the prevention of accidents such as: car crashes and run overs, etc. Our studies indicate that per week it is consumed an average of 2,020.16 liters of gasoline, in schedules of 13 hours (from 7:00 AM to 8:00 PM) to lessen this figure would have a good ecological impact since all the hydrocarbon emission are harmful to health.

Night Vision Goggles

Hadley has create a system that enables you to see in the dark, night?vision goggles. The military version usually retail for thousands of dollars, but Hadley’s solution costs considerably less. And they really work! He has even attached close?fit rubber swimming fittings to the eyepieces to ensure you can’t see a thing without the help of the electronics. The key feature of this project is the way Hadley has used his imagination to access and modify existing technology and explore ways of ‘hacking’ these device to obtain useful component system that he can integrate to make a fully functioning product. In doing this he has encountered many unsuitable combinations, but has persisted to reach an extraordinarily effective endpoint. The whole process, which has taken over a year from initial idea to result is a demonstration of tenacity and ingenuity.

The Free-D Elevator System

Miracles in life originate from daily life itself. What can be imagined can really be achieved. Hong Kong, as an international city, is small in area and densely populated. To utilize space, tall buildings inevitably emerge. Taking elevators has therefore become the daily routine of everyone of us. However, problems abound with the present elevator system. You have probably gone through the dreadful episode of waiting long for an elevator to come, and passage being interrupted by unreasonably frequent stops. Besides, it wastes space, since each elevator tube can only accommodate one elevator. This is why our Free-D Elevator System will revolutionize the present one. It consists of a large cylindrical tube, which can be divided into several smaller, imaginary sector-shaped tubes. In each small tube a large number of elevators move vertically by magnetic levitation. The elevators can also rotate from one tube to another, thereby avoiding collision. This innovative design will substantially increase the number of available elevators for given space. Most importantly, it is highly feasible.
