Small, low cost, simple solar systems reduce the need for oil

Filed under: Energy, Solar — Tags: , , , , — Administrator @ 02:03

Simple solar heating makes good economic sense in uncertain times. It can help save the average homeowner 9.45 barrels of oil per year, more than $1,200 at $130 per barrel – enough to pay back the investment in less then two and a half years – and can help reduce the nation’s dependence on foreign oil.

If you install a mid-sized 25-square meter integrated solar hot water and space heating array in New York State for instance, you will collect about 54,812,780 btu per year with a low-cost 80% efficient system costing about $2,900. This will reduce you energy bills for heating and hot water by about 75%.

This may not seem like a lot compared to the energy use of the United States, which was approximately 97 quads, or 100,000,000,000,000,000 British Thermal Units (btu) in 2002 (1 btu is the energy which raises the temperature of 1 pound of water by 1 degree Fahrenheit). When someone talks about a number so large we often feel that anything that we do will be insignificant and will not matter. And indeed, the 9.45 barrels of oil that one householder might save in a year amounts to reducing the energy use of the nation by only 0.0000000548%.

But let us suppose that everyone in your town of 10,000 homes does the same. Now you and your neighbors will reduce the energy use of the entire nation by 0.000548% and we will not need to import 94,500 barrels of oil.

And if you and everyone in your state of 1 million homes adopted the same small, simple, low-technology solar initiative, you would reduce the overall energy use of the United States of America by 0.0548% and we would not need to import 94,500,000 barrels of oil.

Taking the idea one step further, if all 100 million homes in the nation adopted this simple solar initiative we would reduce the overall energy use of the nation by 5.48% and we could avoid the import of over 9,450,000,000 barrels of oil.

Barrels of oil saved

This is just the first in many small steps that we can each take as individuals to secure a better future for ourselves and our children. Act now. Make a difference.

How to Understand Energy and Save Money

Filed under: Energy — Tags: , , , , , , — Administrator @ 00:24

Niagra Falls

3,673 kg of water falling over Niagara falls creates only 1 kWh.

To generate just 1 kilowatt hour which we waste without worrying or thinking, would require the water volume of 6 residential swimming pools to flow over a 1 meter drop through a generator in one hour!!!!

Many dictionaries define energy as “the capacity to do work”, and power as the rate at which energy is used.

Potential energy refers to the energy that an object has by virtue of its elevation above the earth and the effect of gravity pulling down on it.

Kinetic energy refers to the energy that an object has by virtue of is velocity.

Thermal energy refers to the energy that an object has which can be released by “burning” or oxidizing it.

Electrical energy, which we commonly use to power our homes and businesses, is based on the movement of electrons through a conductor.

When we convert one type of energy to another, we typically lose between 35% to 75% of the original energy as waste heat.

Therefore, creating electricity from burning coal or from harnessing the energy of a water fall (such as a hydro electric dam) requires about 4 units of energy going into the system for 1 unit of electricity being produced.

The watt is defined in most dictionaries as “a standard unit of measure for power, the SI derived unit of power, equal to one joule of energy per second”.

A joule is a huge amount of energy.

One liter of water weighs 1000g, or 2.2 pounds.

If 102g, which is 102ml of water is 1 meter off the ground it has a potential energy of 1 joule.

1 Watt is defined as 1 joule per second.

That means, assuming a 33% efficient conversion of potential energy to electrical energy, that 3 joules per second must be used to create 1 watt of electrical power.

This means that 306 ml, or 306g of water must flow every second over a height of 1 meter to create 1 watt of electricity.
This means that 1101 liters of water or 291 US gallons of water must flow every hour to create just 1 watt of electricity.

26,424, 6990 US gallons of water must flow over a 1 meter drop every day to create just 1 watt of electricity, or a total of 24 watt hours of electricity.

A 16 foot x 32 foot typical residential swimming pool holds approximately 17,000 US gallons, or 64,260 liters of water.

Swimming Pool

If ALL of the water from a typical swimming pool, 17,000 US gallons, 64,260 liters flowed down over a drop of 1 meter to drive an electric generator with a 33% efficiency, we could:

Turn on two 3.5W Unity(TM) brand LED Lights bulbs for over 24 hours.

Turn on a single 13 W compact fluorescent light bulb for 13.5 hours

Turn on a single 40 W bulb for 4.37 hours

Turn on a single 60 W bulb for 2.9 hours

Turn on a single 100 W light bulb for 1.7 hours

Turn on a single 500 W halogen “work light” for 20 minutes

Turn on your 1500 W hair dryer for 6.8 minutes

Turn on your 3000 W air conditioner for 3.4 minutes

Turn on your 8000 W clothes dryer for only 1.28 minutes

Replace your inefficient incandescent and your medium efficiency mercy filled compact fluorescent light bulbs with low cost, high efficiency LED Light bulbs and help create a better future and save money.

Visit Omachron Lighting Corporation for more information about LED light bulbs.

P. S. The sun provides us with an AMAZING amount of heat energy every day – 2 kWh of energy per day per square meter. This is a huge amount of energy and can be cost effectively harnessed.

How to Prevent Skin Cancer

Filed under: Health — Tags: , , , , , , , , — Administrator @ 23:52

Beware – your sunscreen may not protect you from skin cancer and may even pose an additional risk …

It is now a well established fact that ultraviolet rays from the sun are only partially filtered out by our ever diminishing ozone layer; that powerful UVA rays and the less powerful UVb rays can cause sunburns and lead to skin cancer.

Historically, wearing light cotton clothing, a good hat with a brim, such as a classic straw hat, and covering your neck with a loose fitting scarf were a common way to stay cool in summer. This seems logical – prevent the rays of the sun from touching you skin and you avoid sunburns, stay more comfortable, and reduce the risk of skin cancer.

We live in a world where we believe that technology will solve all problems and that newer and more expensive items are better. Many manufacturers of sun tan lotions leave you with a potentially false sense of security that by simply applying their products you will be safe. This concept has been fostered by the concept of a SPF number – a number which leaves you to believe that a higher SPF will protect you from the sun more effectively and longer. Just put it on and “DO NOT WORRY?”

This false sense of security may result in people putting these products on and then exposing themselves to the sun for longer periods under the assumption that they will be completely safe. This may NOT be the case.

Exposure to sunlight ages the skin, causes wrinkles, causes the most common forms of skin cancer – basal cell carcinoma, which rarely becomes deadly, and causes squamous cell carcinoma, which can turn deadly about 1 percent of the time

NOTHING IS BETTER THAN USING CLOTHING, UMBRELLAS AND NATURAL SHADE TO AVOIDING EXPOSURE TO DIRECT SUNLIGHT TO PREVENT SKIN CANCER.

Also consider the sun tan lotion that you use both in terms of its potential effects on your health and its effects on the environment.

Early sun tan lotions were a bit messy and typically relied on inorganic particles such as titanium dioxide and zinc oxide or a combination of both. These materials have been used in cosmetics for many years and are basically considered safe both for people and for the environment. These materials do tend to wash off when bathing, but they offer PROVEN PROTECTION and have a much lesser environmental impact than many of the “NEWER” sun screen products which contain potentially toxic organic chemicals. However, “NEWER” organic sun screens may not wash off but they do “BREAK DOWN” when they absorb UV, hence they become progressively less effective whereas classic, non water proof sun screen which rely on inorganic particles such as titanium dioxide and zinc oxide or a combination of both work well until they wash off… which you can see and remedy!!! The idea that a sun tan lotion can offer “all-day protection”, or even several hours of protection is not reasonable. In addition to the breakdown of many sun screens, the idea of long term protection does not account for sweat and casual rubbing reducing protection.

Groups such as The Environmental Working Group (EWG) have done research that shows 4 out of 5 of the nearly 1,000 sunscreen lotions analyzed offer inadequate protection from the sun or contain harmful chemicals or both. The EWG studies also found that many lotions contained chemicals that would pass quickly and easily into the blood stream such as oxybenzone which only blocks UVA, and was in the urine of people tested. Oxybenzone MAY promote DNA damage in the presence of sunlight, does not filter out deadly UVB rays, so why take a chance with a product which contains this potentially dangerous and partially effective material.

USING A PROVEN SUN SCREEN (a formulation using inorganic particles such as titanium dioxide and zinc oxide or a combination of both) ALONG WITH USING CLOTHING, UMBRELLAS AND NATURAL SHADE TO AVOIDING EXPOSURE TO DIRECT SUNLIGHT TO PREVENT SKIN CANCER.

PROTECT YOURSELF, YOUR FAMILY AND THE ENVIRONMENT.

Solar Pool Heating. Free energy. Or maybe not …

Filed under: Energy, Solar, Swimming Pools — Tags: , , , , , , , , — Administrator @ 14:26

Solar energy should be free…right?…maybe not. Depending on the system you chose solar energy can still cost you a lot of money and waste a lot of electricity!!

Solar energy collection systems such as solar swimming pool heaters typically require a pump to operate. This pump is driven by electricity. Therefore, electrical power (energy) is needed to collect the solar energy. This electricity use must be factored into your considerations when determining the REAL payback of a solar energy capture system.

This does not mean that solar energy is not a good idea. It is a GREAT idea …

It does mean that you must clearly understand the overall costs of solar energy must include the capital and installation cost, and the energy used to operate the system versus the energy collected.

The Solar Energy Capture Efficiency is defined as the solar energy collected by a system divided by the energy that must be input to make the solar collector work. The larger this number is, the less energy is used to collect the solar energy which means that the operating costs are lower and it is better for the environment..

Example:

A solar collector in Southern Ontario, Canada could collect an average of 1,233 btu/sq ft/day (3.887 kWh/day/sq m) during the 6 month period from Mid April through Mid October assuming a 75% collector efficiency.

If a 1.5hp pump is used to pump the water from your pool through your solar collector and filter the energy use is calculated as follows:.

1.5 hp x 746W/hp = 1.119 kWh/hr.

If the swimming pool pump runs 8 hours per day, it will use 8.952 kWh /day, 1,612 kWh in 6 months of use.

At $0.10/kWh, this amounts to $0.90 per day, or about $162 for 6 months. The price of electricity will continue to rise.

The electricity used by the water pump is equivalent to 3,819 btu/hr, or 30,552 btu/day.

Therefore, a 4′ x 20′ solar collector could capture 4 x 20 x 1,233 btu/sq ft/day = 98,640 btu/day.

This means that you must put 30,552 btu/day of electrical power equivalent into your swimming pool filter and solar water heating system to collect 98,640 btu/day, which is a Solar Energy Capture Efficiency of 3.2:1. Many system provide a ratio of only between 3:1 and 6:1.

Solar energy systems are NOT created equal …
Omachron Technologies Inc. has developed more efficient solar collection systems wherein the Solar Energy Capture Efficiency (energy output to energy input ratio) is up to 40:1, which means that they would cost 10 times less to operate than many current products.

Consider the capital cost of your solar energy system and the cost of operating your solar collection system when comparing different technologies.

When you save money and energy, both you and the environment win.

How to help save the coral reefs of the world

Filed under: Environment — Tags: , , , , , — Administrator @ 00:18

Use a hat, shirt, and umbrella and reduce your use of sun screen to help save the coral reefs of the world AND reduce you risk of skin cancer!!!

Coral Reefs are “the Rainforests of the Sea”. They are the natural habitat to thousands of plant and animal species and they are critical to the health of our planet. Coral reefs are threatened around the world due to environmental changes and pollution caused by people.

Many people think that there is nothing that they can directly do to save coral reefs. That is NOT TRUE. While it may be beyond your personal control to reduce the negative environmental impacts of marine debris, over-fishing, run-off pollution, reckless diving and snorkeling habits that can harm the coral reefs of the worlds; there are some simple things that you can do to help save coral reefs and reduce your risk of skin cancer.

There are many different types or coral reefs which include Fringing reefs. They are reefs that form along a coastline and grow on the continental shelf in shallow waters. Barrier reefs grow parallel to shorelines, but farther out and are typically separated from land by deep water. Coral Atolls are rings of coral that grow atop sunken volcanoes in the ocean. The Great Barrier Reef off the coast of North East Australia is over 1,257 miles long and is the largest in the world. Hawaii also has some amazing coral reefs as do the Cayman Islands.

It has been estimated by some experts that global warming can be a threat to the health of our reefs as well. If the water were to rise by just 2 degrees it could lead to the phenomenon known as coal bleaching, in which the coral die and turn white. This has been observed off the coast of Florida. Another aspect of global warming is the rise in sea levels near the shore, leading to more powerful wave action, and stronger currents which can bring potentially dangerous pollutants farther out into the ocean thereby damaging more coral. Scientists from the U.S. Geological Survey have indicated that Hawaii may already be experiencing some erosion due to coral damage along the south shore of Moloka’i.

If you love to walk on white sand beaches, and you want your children and grandchildren to enjoy this, you must help to protect the coral reefs of the world!

If you are out in a boat, do not dump waste into the water as this will harm the local ecology.

Do not wear organic based sun screens, and preferably, do not wear any sun screens when you swim. Wear a T shirt and limit you exposure to the sun and help prevent washing your sun tan lotion into the lakes and oceans of the world. Consider wearing UV protection beach clothing that allows you to swim without getting a sunburn and which reduce the risk of skin cancer.

Use fewer household chemicals and reduce the use of chemicals on your lawn or garden.

Don’t litter or throw cigarette butts on the beach. What’s on the beach will eventually go into lakes and oceans and may be eaten by the fish causing them harm.

Do your part … it’s easy to make a real difference …

The Hidden Costs of Using Electricity

Filed under: Energy — Tags: , , , , , , — Administrator @ 00:58

Your lighting and appliances can use more energy than heating your home!

According to the latest information from the US Department of Energy, and other sources, space heating and electricity for appliances and lighting are equal consumers of energy in a home in terms of cost and combine to represent 68% of household energy use as of 2003.

A typical home uses energy as follows:
Energy consumption in a home
Space heating: 34% Natural Gas or Oil
Lighting: 20% Electricity
Other Appliances: 14% Electricity
Water heating: 13% Natural Gas or Electricity
Air Conditioning: 11% Electricity
Refrigeration: 8% Electricity

A typical home in the Midwest requires 60 to 80 million btu per winter for heating.
This would represent the equivalent energy in 17,579 to 23,439 kWh of electricity.

If lighting accounts for 20% of your energy costs, it actually represents much more energy than your heating systems!

An efficient modern coal fired electric power plant typically operates at 30% efficiency, and a further up to 20% of the electricity generated at the plant is lost in transmission of the electricity.
Energy Loss
Therefore, the energy used to create the electricity to power your lights is at least 2.45 TIMES MORE than the energy used to heat your home.

Whenever possible, we must reduce electricity use because it actually takes about 4.16 kWh equivalent of heat energy from burning oil, gas or coal to produce just 1 kWh of electricity.

Conserve electricity whenever possible. Turn off lights when they are not needed and replace incandescent and compact fluorescent lights with more efficient LED light bulbs which are available in a variety of sizes and provide the right amount of light for your applications.

The best environmentally friendly products are cheaper and last longer

Filed under: Energy, Environment — Tags: , , , , , , , — Administrator @ 00:10

Green buildings, hybrid cars, solar panels, organic food, fair trade goods and more – living an eco-friendly lifestyle is now easier than ever! Environmental awareness and social responsibility associated with product purchases is now becoming an important part of the decision-making process for many of us.

In choosing a sustainable lifestyle, remember that the cost of goods is primarily driven by the cost of energy. Most goods are primarily based upon the cost of materials, other than software, books, etc wherein labor is a significant factor. Increasingly consumers, employees, shareholders, government, non-government organizations and service groups, like insurance companies and banks, are considering social and environmental responsibility as an important part of their operating practices.

However, many purchases made to “benefit the environment” are misguided in that they involve paying for an item with a long payback period compared to the operational life of the product. Therefore, products with a long payback are fundamentally not “sustainable” and do not represent a good use of resources to make. When you look at a purchase, consider the energy savings and potential pollution reduction or avoidance, and consider the payback and the projected useful life of a product.

Products with the MOST environmental benefits will have a pay back period of less than 4 years, and ideally they should pay back in 1-2 years and the useful life of the item should be at least 3-10x greater than the payback period. The shorter the payback period and the longer the useful life, the greater the benefit of the item.

This means that when we use energy to make a product, we can have the greatest impact on climate change, pollution and the associated ill health, by choosing products with a quick payback and a long useful life so that the energy and pollution savings become ever greater.

Also, if you have an environmentally good product you no longer want, give it away to someone who will use it to ensure that the full environmental benefits of an energy saving product are realized. If a product is discarded before its useful life is finished, a portion of the benefits of making the energy efficient and/or environmentally friendly item are lost.

Once a product has reached its useful end of life, reuse the parts or recycle it to ensure that we have a truly sustainable future.

The real energy to change the future

Filed under: Energy, Solar — Tags: , , , , — Administrator @ 16:51

Energy is often defined as the ability to do work.

There are really only a few primary sources of energy available to mankind – the sun, the moon, the earth and nuclear power.

The sun provides us with heat (infra red radiation) which we can absorb, use, or store. The sun also provides visible and ultra violet light which we can convert to electricity and then store as chemical energy. Plants store various wavelengths of visible light and near IR to store in the form of chemical energy. The sun also provides the weather which provides us with water power, wind power and wave power. The sun also causes evaporation which causes powerful ocean currents. All of these secondary solar energy forms can be harnessed by man.

The moon provides us the power of the tides.

The hot molten core of the earth can provide us with geothermal energy.

Nuclear reactions can provide energy in the form of heat and in the future may be able to be converted into other more conventional forms of chemical or electrical energy or a combination thereof.

Oil, natural gas, and coal are all just solar energy which has been stored over millions of years which we are now exhausting within just a few centuries. Oil is the most convenient form of stored energy which we have found because it is an easily stored liquid that is simple to transport, has a high energy density, and is easily combustible yet will not readily explode. Oil is used to make many petrochemicals including gasoline, plastics, and hundreds of thousands of other items. Given the amazing flexibility of oil, should we really just be burning it when we could use the sun to provide many of our space heating, water heating, space cooling, and refrigeration needs?

Historically, it took about 50 years for the world to switch from wood to coal as the primary means of stored energy. It took another 50 years to switch from coal to oil.

The key challenge now is that we must quickly and decisively reduce our oil consumption as a simple energy source and preserve it for use in petrochemicals and other materials where oil cannot easily be replaced.

The first common sense thing to do is to look at how energy is used in the North America, the largest consumer of oil in the world. A quick review of the facts as presented by the U.S. Department of Energy shows the following:
Industrial Energy use – 33%
Residential Energy use – 21%
32% space heating
13% water heating
12% lighting
11% air conditioning
8% refrigeration
5% electronics
5% wet-clean (mostly clothes dryers)
Commercial Energy Use – 17%
25% lighting
13% heating
11% cooling
6% refrigeration
6% water heating
6% ventilation
6% electronics
Transportation Energy use – 28%

If we replace all incandescent light bulbs in America with non polluting long life LED light bulbs (www.omachronlighting.com) we can reduce US energy consumption by 6.77%!

If we replace our inefficient furnaces and hot water heaters with ultra high efficiency furnaces integrated with low cost simple solar space heating and water heating products such as the products developed by Omachron Technologies Inc which pay for themselves in only 1 to 3 years, we could reduce US energy consumption by 12.68%!

If we replace air conditioning, ventilation, and refrigeration systems with solar powered air conditioners such as the products developed by Omachron Technologies Inc which pay for themselves in only 2 to 4 years, we could reduce US energy consumption by 6.88%!

Electricity is our friend… or is it?

Filed under: Energy — Tags: , , , , , , , — Administrator @ 01:47

In 2002 the Unites States of America used 97 Quads of energy which is the equivalent of 97,000,000,000,000,000 btu or 2,800,000,000,000,000 kWh. This is an amount of energy almost beyond comprehension. What is worse is that we WASTED 57.9% OR MORE of this energy became waste heat!!!

An astounding 87.6% of this energy came from fossil fuels including oil, coal, and natural gas.

For over a century, electricity has been distributed to homes and businesses to provide lighting, heating, and cooling, and to drive motors, industrial equipments, and in recent years, computers.

Electricity is a convenient means of distributing energy and it seems clean, neat and efficient to the users of electrical products and appliances. However, the TRUTH is that electricity generation is one of the most wasteful and polluting industrial processes in our current society.

Oil, coal and natural gas represent millions of years of solar energy captured by plants and micro-organisms and captured under ground for us to use. Fossil fuels are an amazing resource that has allowed us to develop an amazing society with an electrical power grid at its heart. Approximately 39.4% of the 2002 US Total Energy Consumption went into making electricity, while only about 27.9% went into transportation!!

Approximately half of the electricity produced in the United States is made by burning coal to create heat. This heat is converted to mechanical work by heat engines at an efficiency of not more than 40%, typically 35%. The mechanical work is then converted to electricity by electromechanical generators with a typical 90% efficiency. Thus, 66-68.6% of the energy available in coal has already been lost in producing the electricity.

The electricity is then distributed through an electrical grid where a further 20% or more of the energy is lost and in the end not more than 25% of the energy available in coal is lost as waste heat.

The electrical appliances that we use are often inefficient. Common motors in products such as vacuum cleaners and fans typically operate at 50% to 65% efficiency thereby create yet more waste heat which is then pumped outside by air conditioning systems running on electricity.

The efficiency of solar photovoltaic systems is typically below 15% and must therefore be very large to produce useful amounts of electricity which would be distributed by inefficient networks. Photovoltaic panels are expensive because huge amounts of energy must be used to create them. This makes large scale adoption of photovoltaics to replace our existing electrical generation infrastructure a bad idea.

A BETTER SOLUTION IS AVAILABLE WITH CURRENT TECHNOLOGY AND OUR EXISTING INFRASTRUCTURE. Whenever possible, use solar energy as heat directly. Drive heating and cooling systems directly with the heat from the sun rather than converting it to electricity. If coal is to be used, burn it in an efficient generator co-located with a home or business that can use the waste heat thereby increasing the efficiency of coal use from 25% to produce electricity to 95% or better to create electricity, hot water, space heating and space cooling.

Our society will continue to use electricity … But we should use it wisely.

We should divert electricity away from space heating, hot water heating, space cooling, and refrigeration which would dramatically reduce our energy consumption.

We should insist on high efficiency mercury free alternatives to incandescent light bulbs.

We should purchase appliances with electrical motors having an efficiency of at least 85%.

We can make a significant difference NOW and we SHOULD.

Electricity can be our friend if used wisely …

Making your swimming pool affordable and helping the environment …

Filed under: Energy, Swimming Pools — Tags: , , , , , , — Administrator @ 01:30

If you want to save more than 70% of the cost of heating and maintaining your swimming pool, follow these simple steps:

STEP 1: Install a floating or fixed pool cover to reduce heat loss from the pool;
STEP 2: Install a low cost solar heating system
STEP 3: Enjoy swimming in your own back yard without the hassle and expense of driving to a cottage or to public pools …

A swimming pool in your back yard is a great way for your family and friends to gather without the cost and energy use to travel to public pools, lakes, or cottages. Inexpensive temporary PVC pools can be bought in supermarkets and taken down after summer. Swimming pools range from expensive concrete or fiberglass permanent structures to inexpensive plastic pools which are installed only for us in summer and put away in the winter.

Medical researchers have found that 78oF a healthy and comfortable temperature for swimming yet many people enjoy swimming in water temperatures of 80oF to 90oF (26.7C-32.2C). Excessive pool temperatures waste energy due to increased evaporation rates (which cause cooling of pool) and also cause chemical used to purify the water to evaporate more quickly.

A swimming pool without a cover will loose 70% if its heat energy as evaporation, 20% as radiation to the sky, and 10% as thermal conduction losses to the air and to the ground. A floating or fixed rigid swimming pool cover with a small R value can reduce energy losses by 75% and is the first step to enjoying you pool at an affordable price.

Most swimming pools are heated with natural gas, electricity, or oil which contribute to air and water pollution as well as the heat-trapping gases that cause global warming and which are quickly becoming very expensive.

Solar water heating technology is a simple, reliable, and cost-effective method of harnessing the sun’s energy to provide for your pool heating needs. Modern solar heating products can work winter and summer, even in areas where temperatures fall below freezing.

Many commercial solar hot water heating systems costs between $2,000 to $4,000, depending on variable factors such as ease of installation, state or provincial codes, safety requirements, and access to financing.

Many of the newer technology solar heating systems such as the products developed by Omachron Technologies Inc. have a cost of $600 to $1,200 and pay for themselves in as little as a single year of operation of your pool. Solar pool heating systems are highly reliable and generally maintenance free. In particularly hot climates, passing pool water through the solar collectors during the evening hours can serve as a cooling mechanism if needed.
