SAFETY

A set of safety rules should be the foremost introduction and focus of the class. These rules attained in the classroom will go with the student into the workforce. The teacher or instructor should post, follow and maintain the set rules as standard practice everyday. All the students should be fully aware of the rules and regulations.

The most important agenda before starting teaching or instruction is to focus on safety, awareness and understanding of key concepts.

THE FOLLOWING ARE BASIC RULES FOR THE CLASSROOM AND SHOP

Any cut or breakage of the skin should result in notation of the event and first aid should be administered to immediately.

Electricity can burn, shock or even kill a person. Before assuming the voltage or amps, be sure to take precautions and take accurate readings, even locking out the circuit..

Capacitors will store up amps and will have the capacity to kill a person for a long time after they are charged. DO NOT ASSUME A CAPACITOR IS DISCHARGED!

Battery acid will burn the clothes and the skin. Always have a flush station nearby and make sure that everyone is well instructed on the use of the station in the event of acid getting on the skin, clothes or in the eyes. Always wear gloves, eye protection and a rubber apron when handling acid batteries.

Lock out and tag any circuits that are being worked on.

Be respectful for others and other's work.

No horse play should be allowed

Organization and order should be maintained in the work area at all times.

No student works alone. Everyone must work with at least one other classmate.

No student should work with any tool, equipment or device that the student has not been trained and certified to operate.

All students must clean up after themselves

Work in a well ventilated area

Shop glasses should be used any time that work is being performed


INTRODUCTION TO BASICS

The concept of renewable energy is as follows:

To produce usable energy with materials, movement or velocities that can be renewed or regenerated as opposed to the non-renewable fuels such as coal and petroleum sources.

The following are some basic terms that will be used.

Students must get an understanding and knowledge of these key terms.

Water

The use of water can be used for mechanical and electrical production. Hydro is another word associated with water as being the same, thus, power that is made from water is called, hydro-power.

Water can be used to create many useful purposes, such as running saws, mills, irrigation, pumps, grinding stones, juicers, tumbling and creating electricity. Most of the time, a wheel or turbine is used to create the motion or action that is needed to operate the machinery or electrical generation stations.

WIND

Through the use of wind, energy can be produced into electricity, compressed air and for mechanical power.

For years upon years, people have used the wind for pumping water, for mechanical power to grind seeds and for running machinery. With the invention of industrialized apparatuses that use electricity to do the work, the inventions of sophisticated windmills have been made to convert the wind currents into usable electrical energy.

SOLAR

The sun produces heat, sunlight and other frequencies that can be transmitted into usable energy. The sun can create intense heat on the earth and can also direct different radiation that can be useful to create forms of energy. The solar panels are composed of solar cells that convert the sun's radiation into electricity through the process called photoelectric effect.

Solar energy can also be converted into heat by using some type of magnification unit. The Fresnel lens can be used to heat materials to high temperatures by concentrating the sun's rays to a focal point. Also mirrors can be used to direct the sun's light to a central focal point. Steam can be produced by using these principles, which can be used to create electricity.

GEOTHERMAL

The heat inside the earth can be used to produce energy and usable heat. When there is usable heat or steam inside the earth, this can be used to heat buildings and water, cook and produce steam that can be used to run turbines to produce electricity.

The earth is known to stay at about 55-57 degrees, but there are areas of the earth that have volcanic activity, radioactive decay or decaying organic material under the surface, creating heat. Depending on the temperature of the underlying ground would determine the amount of usable energy could be extracted. A very high temperature, above the boiling point of water would give an indication that steam could be produced to be used to run machinery, extract heat for heating homes and buildings and to run generators or turbines to produce electricity.

BIOMASS

The organic substances can be changed to produce fuels and other organic materials that can be usable in today's society.

Biomass is composed of carbon, hydrogen and oxygen. Most of the time, it is recognized as wood, grass, organic material, fruit and vegetable matter, but could also consist of animal matter.

The bio-mass could be used straight as a form of heat or converted into other fuels, such as methanol, ethanol, methane, bio-diesel and other forms of combustible fuels.

New technologies are being developed to use different types of bio-mass to produce usable types of fuels. The use of fermentation, distillation, organisms, enzymes, and chemical to transform the organic mass into a dependable, usable flammable liquid.


ORGANIC

Anything organic can be reproduced and regrown, thus being renewable forms of energy.

People have been using trees for years for heating the home and buildings for thousands of years. Within the last 50 years, the scientist have experimented with the genetics to develop hybrid plants to grow faster, stronger and bigger.

The organic material can be converted to usable energy by composting,destructive distillation, fermentation and anaerobic digestion. Yeast is used to break down the sugars into alcohol, composting breaks down certain organic material releasing heat and methane and anaerobic digestion is the breakdown of organic materials in an environment absence of free oxygen by the anaerobic organisms. This anaerobic action produces methane. The destructive distillation is a process where heat is applied to an organic material in a closed oxygen absent environment that drives out usable energy. In the case of wood, the fuel produced would be methanol alcohol.

COMPLEX AND OTHER FORMS OF ENERGY

OK, this will be dedicated to the unknown, fringe areas and to the possibilities of further information of generation and obtaining of new sources of energy.

One of these areas is free energy. Tesla experimented with these types of sources. It is said that Tesla invented a car that could take the electricity directly out of the air. Ben Franklin flew a kite, with a carbon filament string, lit a key at the end of the string. He took the energy directly out of the air or some say that lightening struck it..

The difference between the gradients of the sky and the ground would produce the energy if connected to each other. Lightening would be the great difference of the gradients, which would be released, to be stabilized.

Dear laurenswright,

Thank you for an interesting and comprehensive article. Due to medical reasons I have my house hardwired to a 5kw diesel generator that can run on diesel, furnace oil or vegetable oil. I am planning to put in a deep charge battery bank that can be charged by solar panel, small wind generator or surplus diesel power.

kind regards Peter
