Applications And Advantages Of An Auto Transformer

Posted on February 21, 2018 By In Uncategorized With no comments

Power cuts and voltage variations are one of the common problems of every industry. To fight back with the problem, transformers are the only solution that is used widely in the global industries. The device is ideal for supplying the constant supply of power and also regulating the rise and fall of the voltage supply. Transformers are the stroke of the luck for the industries which are facing the energy distribution and transmission troubles. An auto transformer is an electrical device which has only one winding. It gives you a higher supply of the voltage required for proper application of the device. It uses the principle of self-induction.

Advantages Of An Auto Transformer:-

  • Less Costly: There is a huge range of the transformers available in the market and you need to choose the device for your application. But the auto transformer is known for its eco-friendly nature and affordable prices. They are actually cheaper in cost and high in performance.
  • Compact Size: Every industry is concerned about the space availability for the device to be installed and they generally avoid bulkier, big devices for installation. The device is available in the market in a compact size which can give you better results with the smaller size. It is usually employed to increase the voltage requirement for the application.
  • Voltage Regulation: The main aim of using the device is to regulate the voltage supply to provide the evenly distributed energy for the applications. The two winding device cost you more and there is more copper loss. However, auto transformers are the best at regulating voltage and less copper loss.

Application Usage Of An Auto Transformer:-

  • Power Transmission And Distribution: The device is frequently used in power applications to interconnect the systems with each other and operating with different KVA sizing. Other than this, it is used to adapt the machinery built-in the industry. It is also employed to provide the constant supply of the voltage while providing the average voltage close to the source.
  • Audio System: In the audio applications, the device is used to adapt the speakers to provide the steady voltage to the audio distribution system. It is also employed for matching the impedance.

Railways: The device is arranged to supply the steady power and are also used as the voltage regulator. It gives a small boost to the distribution cable and also corrects the drop. It is used to increase the voltage supply, but due to the single winding operation, it cannot step down the voltage supply.

The Question is, What is a Pressure Transducer?

Posted on February 21, 2018 By In Uncategorized With no comments

In its most basic terms, a pressure transducer measures the pressure exerted on its sensing mechanism and change it to an electrical signal. They are most commonly used to calibrate the pressure that a gas or liquid extracts under variable conditions. They are widely used in aeronautics and oceanographic vehicle manufacture. Various types are made with special conditions in mind, such as measuring pressure performed in a vacuum or when the gas or liquid is exposed to an extreme range of temperatures. The measurements are then recorded onto data loggers.

For example, the most widely used and economic transducer is the strain gauge type. When pressure is exerted on a diaphragm, strain is placed on the instrument gauges. This is then converted to an electrical signal.

The output can take three different forms. Millivolt output transducers are among the least expensive type. They are most useful when the distances involved are short and the environment does not feature a lot of electrical noise. A consistent power supply is necessary for the most accurate readings.

Voltage output pressure transducers are less sensitive to electrical noise. The power supply is also not as important as with millivolt transducers. The final type of output is a 4-20 mA output pressure transducer, sometimes called a pressure transmitter. These types are often used when lead wires must span a long distance. Least susceptible to electrical noise and power fluctuations, these types can utilize lead wires of around 35 yards or more.

Pressure transducers are further categorized based on other factors. The type of sensor and type of pressure is one indicator. Absolute sensors test in a true absolute vacuum. Gauge sensors test relative pressure. Differential pressure sensors test the difference between two or more pressures. And a sealed sensor is calibrated and then sealed to measure pressure in terms of a known pressure, usually at sea level.

Pressure transducers are also classified into two basic categories. The first are the force collectors, which use a bellows, piston, or diaphragm. The second category is basically all transducers that are not force collectors, and encompasses thermal and resonant transducers. Strain gauge transducers fall in the category of force collectors, as are capacitive transducers commonly used to take readings under low pressures. Piezoelectric transducers, which are often used to test combustion in automobile engines, are also force collectors. The resonant and thermal transducers check the density of a test gas while under pressure, and are often used to take multiple readings over an extended length of time.

Anyone asking, "What is a Pressure Transducer?" may also wonder about some of their applications. They are important tools to manufacturers of aircraft, automobiles, weather instruments, and satellites. From rockets to weather balloons, pressure transducers are used to measure the effects of changes in air pressure. They are also used to help submarines measure depth. In addition, several industries use them to test pressurized systems for leaks.

Miller Welding Vs Lincoln Welding – Who’s the Best?

Posted on February 21, 2018 By In Uncategorized With no comments

Miller welding company is a class act.

I have a choice when it comes to the welding machine I use. I could choose to use ESAB, Lincoln Welding, Fronius, Panasonic, and a bunch of others. But I choose Miller Welding equipment. Why? There are actually several reasons but the number one reason is the people. Every Miller Electric representative that I have dealt with has been knowledgeable and more than helpful. After visiting the Miller Welding equipment headquarters in Appleton, Wisconsin, and seeing the rigorous testing the welding machines go through, I am even more convinced that they make quality welding machines.

I attended a focus group type seminar once that was mostly comprised of technicians that repaired welding machines. They all preferred working on Miller welding machines. When I asked why, they all agreed that customer support, parts availability and dependability, were big factors that impressed them.

I have welded with Miller, L-Tec, Linde, Lincoln, Hobart, and even JC Penney welding machines. Honestly, if someone were to paint them all black, I am not sure I could tell some of them apart by the arc (The JC Penney one, I definitely could tell). But the customer support thing, thats what makes the difference. If I have a problem with a machine that is still under warranty, I dont get some jerk on the phone asking me what I did wrong. What I do get is the Miller Welding Rep making sure my machine gets picked up and sent to the repair shop and returned to me good as new.

I have heard some stories about the customer support of other welding machine companies. I have also heard that most of the big welding machine companies are stepping up to the plate now. But Miller set the bar.

Simple Approach for AC Drive Repair

Posted on February 21, 2018 By In Uncategorized With no comments

AC drives are the most efficient devices as they supply an adequate amount of electrical power to a given electric motor system or motor drive. This device is highly energy efficient and is mostly employed for good orientation and process control in an industrial application. AC drives also known as variable frequency drives are mainly used to supply electrical power to industrial applications like induction motors and synchronous motors. Such a drive is also referred to as Adjustable Speed ​​Drive. It is an integral component in all electronic and electrical applications.

The Basic Need for AC Drive Repairs

We live in a modern technological world where every electrical and electronic systems or devices are likely to suffer certain wear and tear problems. This is because such devices are used for prolonged hours. Similarly, in case of variable frequency drives, these devices need timely maintenance and repairing in order to function smoothly and avoid stress and wear out problems. However, the components provided on variable frequency drives are likely to face breakdown due to factors like overvoltage or voltage notches. In such situations, it is highly necessary to perform AC drive repair and timely maintenance to ensure the smooth working of the units.

Many times, several consumers neglect the initial signs of wear or fatigue in the devices that they own and realize later on that the drives completely fail because of their negligence. Some even fail to understand the importance of the simple repairing or refurbishment procedure that can actually improve the device and make it more cost-effective. Therefore, it is highly critical to plan out on replacing the variable frequency drive component or carry out the simple repair procedures in a timely manner.

AC Drive Repair Procedure

When the service company receives your drive for repair works they run a visual inspection and evaluation on the drive to ensure whether the unit is meant to be repairable or replaceable. In most cases, the service company quotes the drive and waits for customer's approval before going ahead with the repair process. Once this has been clarified, the following are the steps that are conducted in the repair process.

  • At the service center, the entire unit is cleaned and the components are static tested by skilled technicians.
  • The technicians scrutinize the unit and troubleshoot the circuitry for faulty or damaged areas.
  • Once the AC drive repair is completed, the drive is then tested on an efficient load tester to check the true world conditions.
  • This is the last step of the repair process, whereby, the service center generates a service report that consistors of findings and an elaborate understanding of why the drive stopped functioning or failed initially.

Once the drive has been serviced, the service centers carry out rigorous tests under high-stress conditions just to make sure the units are reliable and perform well. It is advisable to look out for trusted service providers so that you gain efficient result and good reliability in your product.

The Benefits of Electric Heating

Posted on February 21, 2018 By In Uncategorized With no comments

Electric heating is making something of a comeback. With natural gas prices soaring and uncertainty in its future availability, electric heating systems are the preferred choice of those who wish for an efficient heating system and peace of mind with a more environmentally friendly alternative to gas central heating. So what are the benefits of an electric heating system?

What is Electric Heating?

Essentially, an electric heating system converts electricity into heat. Like an electric kettle, the electric boiler heats water via an element then pumps the water through the building's radiator network. Domestic systems do require a boiler but, because of their smaller size compared to gas boilers, they can be located more discreetly and in smaller spaces.

Efficiency of Electric Heating

Compared to gas central heating, electrical is far more efficient and reliable:

  1. Easy to install as there is no flue required.
  2. Electric boilers can run at 100% efficiency.
  3. Quick response times – hot water from taps within 5-10 seconds, radiators heat to maximum temperature within 3 minutes.
  4. Simple, user friendly controls enable quick and easy temperature control, room by room.
  5. Few moving parts means no annual service, quick and easy repair and maintenance.
  6. Longer life span than a gas boiler – 10 years for gas, 15 years for electricity.
  7. Durable components.
  8. Good safety record – no need for a flue or ventilation.
  9. Quieter operation than gas.
  10. Mains pressure hot water – power showers do not require a booster pump.
  11. No storage or header tanks required.
  12. Provided constant room temperatures.

Helping Your Pocket

Because of the simplicity of electric boilers, electric heating users rest safe in the knowledge that there is little or no energy waste. In addition, electricity usage for heating can be monitored accurately, which helps future domestic budgets.

Users of electric central heating systems have lower running costs than gas users as they have the option of peak avoidance tariffs to help keep running costs down, something gas users can not use for their central heating. In the UK, two popular tariffs are Economy 7 and Economy 10. Economy 7 splits electricity use for heating into day and night (7 hours on an off-peak rate during the night). Economy 10 offers 10 hours of off-peak electricity. The beauty of these tariffs means that you have the choice of running heating and other appliances during off-peak times.

Helping the Environment

Both gas and electricity prices have suffered in recent years. Most electricity is created from gas-fired power stations, so if gas prices rise so do electricity prices. However, the move towards sustainable electricity generation is well underway. Wind farms account for increasing amounts of generated electricity year on year, and Governments around the world continue to cooperate to make electricity more abundant and affordable. This type of electricity generation is not only good for the environment; it is good for end users reliant on electricity for heating. Another environmental benefit of electric heating is that there are no emissions. This not only has a positive effect on the wider environment, but also within buildings as it contains clean, healthier living and working spaces.

The Legal Issues Of Engineering And Constructing A Microbrewery

Posted on February 21, 2018 By In Uncategorized With no comments

In the engineering and construction of a microbrewery there are numerous areas where legal issues come into play from concept to completion. This article will attempt to outline some of the legal issues one must ponder while progressing through the entire engineering and construction process of a new 15 barrel (bbl) microbrewery. The process will be divided up into two distinct sections – engineering design and construction.

Let us begin the engineering design process with the owner’s concept: “I want you to design a 15 bbl microbrewery for me”. As an astute engineer, you know that you need a written contract. This written contract must clearly contain several elements in order to be valid. These elements are: competent parties, agreement (offer and acceptance), consideration, lawful purpose, and form. The competent parties would be the owner and you (or your engineering company). The agreement would be your offer to design and engineer the microbrewery, and his acceptance would indicate and agreement. The consideration would be that you receive a fee (for instructional purposes let’s say you charge a flat fee to design building plans that will be accepted by the permit office for construction. The owner’s consideration would be those completed building plans that are accepted by the permit office, thus being ready to use for construction. The contract must be for a lawful purpose, in this case, the design and engineering of a microbrewery. The form, of course, would be the written form outlining all of the above elements. Now, that the basic elements of the contract are known, you must now work with the owner to get some answers that will help you design this new microbrewery.

Since the microbrewery is going to be a 15 bbl system, you might need details like:

What is the maximum annual production capacity expected?

What type of beer will be produced (ale, lager, stout)?

How will the beer be packaged (bottles, cans, kegs)?

You are asking these questions because they are needed to determine the size of the facility, as well as what special items must be designed. For example, the owner says he wants to be able to brew and store three brews a week. Knowing this you now have to calculate enough space and equipment to handle a maximum annual capacity of 2250 barrels at 50 brewing weeks per year.

Calculation of Annual Production

System Size (Brewhouse Size) x Number of brews per week x 50 weeks per year = Annual Production 15 Barrels (bbls) x 3 brews/week x 50 weeks/year = 2250 bbls/year

The owner also says that he wishes to brew both ales and lagers – 50% ale production and 50% lager production. You also know that each type of brew has a different cycle for brewing, and thus you need a different amount of fermenters per type of beer.

Calculation of Number of Fermenters

2250 bbl Annual Production Capacity (50% Ale, 50% Lager)

14 Day Ales / 28 Day Lagers with full fermentation in fermenters Ales – 25 cycles / fermenter / year (50 brewing weeks / 2 week fermentation) Lagers – 12.5 cycles / fermenter / year (50 brewing weeks / 4 week fermentation)

Ales: 1125 bbls / year / (15 bbls x 25 cycles/year) = 3 Fermenters Lagers: 1125 bbls / year / (15 bbls x 12.5 cycles/year) = 6 Fermenters Total: 9 – (15 bbl) Fermenters to produce 1125 bbls Ales and 1125 bbls Lagers

This information will affect the dimensions of the microbrewery. You know that ales ferment ideally between 65 and 75 degree F, but you also know that lagers ferment below 65 degrees and must age longer in lager tanks, so you must add not only a “hot room” for brews but also a “cold room” for the lager tanks and dispenser tanks. The owner says that he wants to dispense the beers in ½ bbl kegs and 12 oz bottles. He also stipulates that he needs enough space to store a month’s worth of each type of container. So, based on this requirement you need to calculate the space required for the bottling and kegging machinery, as well as the storage space for a month supply of ½ bbl kegs and 12 oz bottles.

Of course, you will need to figure out the other requirements specific to the microbrewery, such as water needs, drainage, floor finish, electrical, ceiling heights, venting, loading and unloading areas, etc. Slowly but surely the picture of what needs to be designed is coming together. As an engineer, you will need to ask many questions, and get answers to those questions, so that you can clearly outline the specifications of what needs to be built in the contract. In addition, by getting these specifications in writing you are further eliminating any ambiguities there might be which could be used to not honor the contract, or which could be used against you if you must go to court to resolve a contract dispute.

After several weeks of hard work, you finish the project, submit the plans for approval, and they are approved. You present the approved plans to the owner as consideration for your services, and as consideration you are paid your fee.

After having been pleased with your design and engineering services, the owner now asks you to be the general contractor for the construction phase of the project. He asks you to supply him with a bid as soon as possible. You call your suppliers to get prices, availability, lead time for delivery, etc. You receive bids from subcontractors for the various trades (plumbing, electrical, HVAC, flooring, etc). You pick those subcontractors that you think best fit your needs.

In addition, you have done your due diligence by making sure all your subcontractors are licensed, that they are carrying their own forms of liability insurance, and that their workers will be covered in the event of injury. As a general contractor, you, of course, must also be licensed, possess liability insurance, surety bonds, workman’s compensation insurance, etc. These are all instruments that help protect you legally in the event that any liability or injury issues arise during the construction of the microbrewery.

When preparing the contract for the bid (and the job) you ensure that the specifications contain all of the critical elements such as: general provisions, the schedule of work, change order procedures, drawings, receipt and storage of materials, warranty on labor, warranty on materials, methods of payment, procedure for lien release, etc.

Once you have collected your information you submit your bid, and the owner accepts. Of course, there may be many different contracts involved here: the contract between the owner and you (the general contractor); the contracts between you and the subcontractors; and the contracts between you and your suppliers.

Finally, the first building supplies arrive, construction begins, and within several months, you and your team have constructed a new top-of-the-line microbrewery, adding value to the community, the nation’s economy, as well as putting a little money in your pocket.

Now, let’s review. Along the way there were several areas where you could have encountered potential legal pitfalls. In the engineer role, you made sure that the contract contained all of the elements necessary for it to be valid: competent parties, agreement (offer and acceptance), consideration, lawful purpose, and form. Also, based on the owner’s input, you made very detailed specifications of the microbrewery design and you put it in writing. This helped prevent any ambiguities between what the owner wanted and what you thought the owner wanted; furthermore, you put the design specifications in writing.

In the general contractor role, you had to deal with potential legal pitfalls involving the contract between you and the owner, you and your subcontractors, as well as you and you suppliers. You possibly had to encounter labor issues, liability issues, injuries, workman’s compensation insurance claims, incorrect building supply deliveries, theft or damage of materials or equipment on the job site, or maybe even attractive nuisance issues. Whatever you might have encountered as an engineer and as a general contractor you know that you are armed with the knowledge to jump over any legal issues you may encounter. It’s time to have a beer!

Understanding Compact Fluorescent Lighting (CLFs)

Posted on February 21, 2018 By In Uncategorized With no comments

Compact Fluorescent Lighting (CFL) has been so successful in replacing the traditional light bulbs (incandescent) and fit in existing light fixtures to produce more energy-efficient lighting. Edward Hammer developed the spiral shaped bulb to try to pack in enough tube yet allow enough space between the coils to decrease blockage of light. Today, Hammer’s spiral design endures, although rectangular tubular-type CFLs are a bit more efficient and are more popular in Europe.

There are two main components of a CFL:

  1. The ballast, which emits and moderates electric current (typically in the ‘bulb’ part of light)
  2. The gas-filled tube, also known as the bulb

The CFL tube is filled with an inert gas, typically argon but sometimes neon. This may also include a small amount of mercury vapor. As the larger fluorescent tubes, excited mercury atoms produce UV light. This strikes the phosphor coating on the inside of the glass tube or bulb to emit visible light.

In all fluorescent bulbs, the phosphor coating is a key part of the design and is constantly evolving. It is primarily the part of the bulb that produces light color, strength and quality. Today, most CFLs use a layering of two or three phosphors and in some occasions a five layer phosphor. Most CFLs have electronic ballasts, although some earlier models used a magnetic ballast that would cause a flicker in the light it produced and would sometimes hum.

Integrated vs Nonintegrated CFLs

CFLs can be manufactured as integrated or nonintegrated units. Integrated lamps combine the tube and ballast into a single product and have either an Edison screw-type or bayonet fitting. These are the CFLs that ar most familiar to consumers and they allow simple replacement of incadescent bulbs. This lowers the coast of use because people can actually reuse existing hardware.

Nonintegrated CLFs have a separate replaceable bulb and permanently installed ballast. Since the ballasts are placed in the light fixture, they are larger and last longer than the integrated ones. Nonintegrated housing tends to be more costly ranging anywhere from $85 to $180 for each recessed light fixture.

Direct Current (dc) CFLs

Most fluorescents will work on dc as long as there is enough voltage to sustain an arc. Unless the starting switch is arranged to reverse the polarity of the supply to the lamp each time it is used, the mercury in the tube will accumulate at one end of the tube. One alternate solution for this problem is to hook up an inverter before the fluorescent light, which will convert the power from dc to ac.

Advantages of CFL Lighting

Most residential CFLs opperate on 12 to 24 watts of energy which is far less than the typical 60 to 100 watts for incandescent bulbs. The great thing about this type of lighting is the CFL is still able to produce the same amount of light with a fraction of the energy. CFLs also have a longer life, sometimes 8 to 10 times that of an incandescent bulb. Even though the CFL bulbs cost more, with a longer life and a fraction of the energy use, you can expect to save anywhere from $25 to $35 over the life of the bulb according to the EPA.

Come on America – Lets Go Electric Now! What Are We Waiting For?

Posted on February 21, 2018 By In Uncategorized With no comments

Plug-in-Hybrids (PH's), all Electric Vehicles (EV's), and PHEV's are all available now or in 2010. If enough Americans set the right example, we can lead the rest of the world in avoiding the doubling of CO2 emissions before that target date of 2050. We can not risk dawdling for the next 40 years or even a small part of that because the exploding economics of India and China need the right example to follow starting now. That includes US state and federal legislators especially!

Lack of enlightened leadership regarding incentives and legislation to control emissions has allowed the petroleum-automotive industrial complex to drag their feet. They have continued to promote gas hog SUV's and pick ups (PU's) at the expense of our future. They have been purposely slow to develop PH's, EV; s and PHEV's, holding on to inefficient technologies to appease the greed of the petroleum companies, while the EV technology has exhausted since the time of Henry Ford and Thomas Edison. The US has actually increased it's emissions rate since the Kyoto Conference. Consumers are ready. Look at the success of the Prius and Insight. Forty percent of consumers polled recently say they will go electric in the near future.

An EV puts out zero emissions locally but they are recharged from our 'Dumb' grid. Half of our available power STILL comes from DIRTY coal. That that EV's represent a 30% reduction in emissions of CO2 and polluting particles. As the grid becomes smarter and supplies all of our energy from 100% renewable sources, EV's will realize their potential of 100% efficiency, true ZERO emissions. The near future is cleaner and brighter and global warming can be stopped.

PHEV's like the Toyota Prius and the Honda Insight get from 40 to 60 mpg. We can trade up now and double our milage while cutting the cost by half and cutting our emissions to zero locally. Can you imagine paying half what you do now for gasoline? If you use half as much gasoline you have cut your car's carbon footprint by 50%! In addition you will be cutting your out put by 30% more in the larger dumb grid picture, When the grid is completely based on clean renewable sources, you will have true ZERO emissions. What are we waiting for? You can, right now, cut your footprint by 100% by using an EV for short trips. Consider commuting and shopping with an Electric moped, motor bike, or motor scooter. Please start setting the right example today? The Coda Sedan is all electric and will also go 100 miles per charge.

Smart grid technology is coming but we already have enough power in the grid to switch to EV's and PHEV's. Since they could be charged during peak hours, we can charge over 70% of our existing fleet, assuming we could convert the fleet to all electric overnight. Renewable energy from wind and solar could fill the gap. Smart grid technology will allow us to plug in while at work where our EV battery could actually supply energy to the grid during peak needs, while allowing solar roof sources to recharge it for the commute home. During evening hours, our batteries could supplement home needs, recharging late at night for the morning drive.

Most of the new PHEV's are extended range vehicles, designed to achieve over 100 miles per charge. After that the backup gasoline engine will help power the vehicle. That all electric range is good enough to get 80% of America's commuters to work, and back! The PH's Prius and Insight are getting 40 to 60 mpg now. The Chevrolet Volt is expected to get 230 mpg. Yes, TWO HUNDRED THIRTY miles per gallon! What does that do for your gas budget? And the Volt will go 40 miles on a charge alone before the gas engine has to assist. Electric golf carts, electric mopeds, motor bikes and motor scooters have been around for some time. People who use them enjoy an expense of about 3 cents per mile versus 13 cents per mile for a gas vehicle, and that is at current gas prices.

Ford, Mitsubishi, and Toyota plan on all electric vehicles to hit the production line by 2011. But what is available in 2010? Chrysler's General Electric Motor division has produced the all electric GEM E4. The Nissan Leaf expects to get 100 miles per charge and Nissan plans an extensive expansion of charging stations nationally to accommodate their intended sales! Click on the link below for more information on the Coda. So, "Lead, Follow, or Get Out of the Way!" Start commuting all electric now, or, trade up to a Volt or Coda next year, or, switch to mass transit tomorrow!

Home Improvement Solutions That You Can Use

Posted on February 21, 2018 By In Uncategorized With no comments

Home improvement makes a great hobby. After all, it builds useful skills, creates a sense of empowerment, and of course it improves the function and look of your home. There are lots of ways to do it, some right and some wrong. Check out these tips so the time you spend on home repair projects will all be time well spent.

Get new tiling. If your tiling does not match your walls, or is cracking and becoming damaged, replacing it is a better way of refurbishing your home that is solely simple and inexpensive. Stick-on floor tiles are available at many house improvement stores, and if you want to use the real ones, they are not too expensive either.

You need to make sure that you are getting the best price for your building supplies when you are doing any repairs or renovating your homes. All building supply stores carry the same materials but they all charge different prices for the materials. In order to get the best price you need to compare all of the prices at the different stores.

No matter what project you tackle with you home repair, stay safe while doing it. Wear the proper safety protection for your eyes and hands. Read the operation manuals for the power tools that you are going to use. If you do not feel comfortable with anything and it seems dangerous, hire a contractor to do that part.

Almost all Do-It-Yourself projects are pretty easy and self-explanatory. Most people can paint a room, clean storm windows, and make minor repairs. Be careful not to overextend your actual Do-It-Yourself abilities in more complex areas. Unless you really know what you are doing, you are likely to have trouble (and encounter danger) with projects such as Do-It-Yourself electrical wiring and DIY sewer line replacement. Call an expert!

Adding casual living areas to a home, is a smart and profitable home improvement project. Many homes have just one living area, the addition of a second that can be used as a family room or den are big plus to potential buyers who see your home as place that they can grow with their own family.

Follow the above tips, and the investments you make into home improvements will be wise expenditures of both your energy and the resources it takes to complete a project. From the smallest project to the most complex, home improvement can be rewarding and worthwhile in many ways – as long as you pay attention to tips like these.

Will Free Energy Ever Be a Reality?

Posted on February 21, 2018 By In Uncategorized With no comments

I remember from my childhood, reading about visions of the future. One feature that they often included was the notification that we would one day invent a free energy source that would power all our needs and help us live out a utopian lifestyle. The same notification often crops up in science fiction as well. Take those lithium crystals in star trek for example, they seemed to produce a fair bit of energy, by just being there.

Despite being well into the 21st century now, I am not aware of any source of free energy available to power my home or propel my car. I can cope with the reality of that now I am a grown man, but had you told me 30 years ago that this would be the case; I would have been very disappointed.

Thinking back to these childhood memories last week, I decided to have a trawl through some of the writing on the subject to see if there were anyventions in the making that might have the potential to deliver, sometimes in the near future, my dream of free energy. Nuclear power often crops up as the most likely candidate. But with the problems associated with this form of power I am cautious about investing my dreams in the nuclear power industry. Other candidates that may yield something, so their supporters argument, are magnetic motors and the inventions of a certain Nikola Tesla.

Let's look at Tesla first. It would appear that despite being less well known than Thomas Edison, it was Tesla who won the argument when the two clashed in the late 1800's over which was the most efficient form of electricity. It was Tesla's idea about alternating current that is used to this day. Moving into the 20th century, he teamed up with some top industrialist who clearly recognized his genius. For a number of years Tesla was working on a project that promised free energy for all via a 'giant dynamo' to be built using the natural forces of the earth. However before anything was disclosed, his funding was withdrawn. Many believe that his funders realized he was close to inventing a form or free or cheap energy that strengthened their established energy businesses. Here they dropped his funding. Those who have looked into the work of Tesla claim to have produced devices that produce the free energy that Tesla was describing, but only on a small scale.

Another area that may yield our free energy machine is the magnetic motor. Using the forces of the earth's magnetism, believers in these motors claim that they can build machines that produce free renewable energy. It seems the real stumbling block is to build one large enough to produce commercial amounts of power. Nonetheless it looks that there is something for the inventors to work on here.

It would appear therefore if you want to be the one who delivers my boyhood dream of free energy for all, then you might want to focus some effort looking more closely at magnetic motors and the work of Nikola Tesla.
