Whoever needs to get a real appreciation of the greatness of our age ought to research the historical past of electrical improvement. There he’ll discover a story extra fantastic than any story from Arabian Nights. It begins lengthy earlier than the Christian period when Thales, Theophrastus and Pliny inform of the magic properties of electron� the valuable substance we name amber� that got here from the pure tears of the Heliades, sisters of Phaeton, the unlucky youth who tried to run the blazing chariot of Phoebus and almost burned up the earth. It was however pure for the vivid creativeness of the Greeks to ascribe the mysterious manifestations to a hyperphysical trigger, to endow the amber with life and with a soul.

Whether or not this was precise perception or merely poetic interpretation continues to be a query. When at this very day most of the most enlightened individuals assume that the pearl is alive, that it grows extra lustrous and delightful within the heat contact of the human physique. So too, it’s the opinion of males of science that a crystal is a dwelling being and this view is being prolonged to embrace the whole bodily universe since Prof. Jagadis Chunder Bose has demonstrated, in a collection of exceptional experiments, that inanimate matter responds to stimuli as plant fiber and animal tissue.

The superstitious perception of the ancients, if it existed in any respect, can subsequently not be taken as a dependable proof of their ignorance, however simply how a lot they knew about electrical energy can solely be conjectured. A curious reality is that the ray or torpedo fish, was utilized by them in electro-therapy. Some previous cash present twin stars, or sparks, resembling may be produced by a galvanic battery. The data, although scanty, are of a nature to fill us with conviction that a number of initiated, at the very least, had a deeper information of amber-phenomena. To say one, Moses was undoubtedly a sensible and skillful electrician far prematurely of his time. The Bible describes exactly and minutely preparations constituting a machine through which electrical energy was generated by friction of air towards silk curtains and saved in a field constructed like a condenser. It is extremely believable to imagine that the sons of Aaron have been killed by a high-tension discharge and that the vestal fires of the Romans have been electrical. The belt drive should have been recognized to engineers of that epoch and it’s troublesome to see how the plentiful evolution of static electrical energy might have escaped their discover. Beneath favorable atmospheric circumstances a belt could also be reworked right into a dynamic generator able to producing many putting actions. I’ve lighted incandescent lamps, operated motors and carried out quite a few different equally fascinating experiments with electrical energy drawn from belts and saved in tin cans.

That many information in regard to the delicate pressure have been recognized to the philosophers of previous might be safely concluded, the marvel is, why two thousand years elapsed earlier than [William Gilbert] in 1600 revealed his well-known work, the primary scientific treatise on electrical energy and magnetism. To an extent this lengthy interval of unproductiveness could be defined. Studying was the privilege of some and all info was jealously guarded. Communication was troublesome and sluggish and a mutual understanding between extensively separated investigators onerous to succeed in. Then once more, males of these occasions had no considered the sensible, they lived and fought for summary rules, creeds, traditions and beliefs. Humanity didn’t change a lot in Gilbert’s time, however his clear teachings had a telling impact on the minds of the discovered. Friction machines have been produced in speedy succession and experiments and observations multiplied. Progressively worry and superstition gave method to scientific in-sight and in 1745 the world was thrilled with the information that Kleist and Leyden had succeeded in imprisoning the uncanny agent in a phial from which it escaped with an indignant snap and damaging pressure. This was the delivery of the condenser, maybe probably the most marvelous electrical gadget ever invented.

Two large leaps have been made within the succeeding forty years. One was when Franklin demonstrated the id between the mild soul of amber and the awe-inspiring belt of Jupiter; the opposite when Galvany and Volta introduced out the contact and chemical battery, from which the magic fluid might be drawn in limitless portions. The succeeding forty years bore nonetheless larger fruit. Oersted made a big advance in deflecting a magnetic needle by an electrical present, Arago produced the electro-magnet, Seebeck the thermo-pile and in 1831, because the crowning achievement of all, Faraday introduced that he had obtained electrical energy from a magnet, thus discovering the precept of that fantastic engine�the dynamo, and inaugurating a brand new period each in scientific analysis and sensible software.

From that point on innovations of inestimable worth have adopted each other at a bewildering price. The telegraph, phone, phonograph and incandescent lamp, the induction motor, oscillatory transformer, Roentgen ray, Radium, wi-fi and quite a few different revolutionary advances have been made and all circumstances of existence eighty-four years which have since elapsed, the delicate brokers dwelling within the dwelling amber and lodestone have been reworked into cyclopean forces turning the wheels of human progress with ever growing velocity. This, in short, is the fairy story of electrical energy from Thales to the current day. The unattainable has occurred, the wildest goals have been surpassed and the astounded world is asking: What’s coming subsequent?

ELECTRICAL POSSIBILITIES IN COAL AND IRON

Many a would-be discoverer, failing in his efforts, has felt the remorse to have been born at a time when every thing has been already completed and nothing is left to be executed. This misguided impression that, as we’re advancing, the chances of invention are being exhausted, is just not unusual. In actuality it’s simply the other. Spenser has conveyed the best concept when he likened civilization to the sphere of sunshine which a lamp throws out in darkness. The brighter the lamp and the bigger the sphere the larger is its darkish boundary. It’s paradoxical, but true, to say, that the extra we all know the extra ignorant we turn out to be within the absolute sense, for it is just by means of enlightenment that we turn into acutely aware of our limitations. Exactly one of the crucial gratifying outcomes of mental evolution is the continual opening up of latest and larger prospects. We’re progressing at a tremendous tempo, however the fact is that, even in fields most efficiently exploited, the bottom has solely been damaged. What has been to date completed by electrical energy is nothing in contrast with what the longer term has in retailer. Not solely this, however there at the moment are innumerable issues carried out in old style methods that are a lot inferior in financial system, comfort and lots of different respects to the brand new technique. So nice are some great benefits of the latter that each time a chance presents itself the engineer advises his shopper to “do it electrically.”

Think about, in illustration, one of many largest industries, that of coal. From this worthwhile mineral we mainly draw the solar’s saved power which is required to satisfy our industrial and business wants. In response to statistical data, the output in america through the previous yr was 480,000,000 tons. In good engines this gasoline would have been adequate to develop 500,000,000 horse-power steadily for one yr, however the squandering is so reckless that we don’t get greater than 5 per cent of its heating worth on the typical. There’s an appalling waste in mining, dealing with, transportation, retailer and use of coal, which could possibly be very a lot lowered by way of the adoption of a complete electrical plan in all these operations. The market worth of the yearly product can be simply doubled, and an immense sum added to the revenues of the nation. What’s extra, inferior grades, billions of tons of that are being thrown away, is perhaps turned to worthwhile use.

Comparable issues apply to pure fuel and mineral oil, the annual lack of which quantities to tons of of tens of millions of dollars. Within the very close to future such waste shall be appeared upon as felony and the introduction of the brand new strategies can be pressured upon the house owners of such properties. Right here, then, is an immense subject for using electrical energy in some ways, huge industries that are sure to be revolutionized via its in depth software.

To provide one other instance, I’ll discuss with the manufacture of iron and metal, which is carried on on this nation on a scale really colossal. Over the past yr, however unfavorable enterprise circumstances, 31,000,000 tons of metal have been produced. It might lead too far to dwell on the chances of electrical enhancements within the manufacturing processes themselves, and I’ll solely point out what’s more likely to be completed in utilizing the waste gases from the coke ovens and blast furnaces to generate electrical energy for industrial functions.

Since within the manufacturing of pig-iron for each ton about one ton of coke is employed, the yearly consumption of coke could also be put at 31,000,000 tons. The combustion within the blast furnaces yields, per minute, 7,000,000 cubic ft of fuel of a heating worth of 110 B. T. models per cubic foot. Of this complete, with out making particular provision, four,000,000 cubic ft could also be made obtainable for energy functions. If all the warmth power of this fuel could possibly be reworked into mechanical effort, it might develop 10,389,000 horse-power. This result’s unimaginable, however it’s completely practicable to acquire 2,500,000 horse-power electrical power on the terminals of the dynamos.

Within the manufacture of coke roughly 9400 cubic ft of fuel are advanced per ton of coal. This fuel is superb for energy functions, having a mean heating worth of 600 B. T. models, however little or no is now utilized in engines, largely due to their nice value and different imperfections. A ton of coke requires about 1.32 tons of American coal; therefore the whole coal consumption every year on the above foundation is almost 41,000,000 tons, which give, per minute, 733,000 cubic ft of fuel. Assuming the yield of surplus or wealthy fuel to be 333,000 cubic ft, the stability of 400,000 cubic ft might be utilized in fuel engines. The warmth contents can be, theoretically, enough to develop 5,660,000 horse-power, of which 1,500,000 horse-power might be obtained within the type of electrical power.

I’ve devoted a lot thought to this industrial proposition, and discover that with new, environment friendly, extraordinarily low cost and easy thermo-dynamic transformers not lower than four,000,000 horse-power might be developed in electrical turbines by using the warmth of those gases, which, if not totally wasted, are solely partially and inefficiently employed.

With systematic enhancements and refinements a lot better outcomes might be secured and an annual income of $50,000,000 or extra derived. The electrical power could possibly be advantageously used within the fixation of atmospheric nitrogen and manufacturing of fertilizers, for which there’s a limiteless demand and the manufacture of which is restricted right here on account of the excessive value of energy. I anticipate confidently the sensible realization of the venture within the very close to future and look to exceptionally speedy electrical improvement on this course.

HYDRO-ELECTRIC DEVELOPMENT

Water-power gives nice alternatives for novel electrical purposes, notably within the division of electrochemistry. The harness of waterfalls is probably the most economical technique recognized for drawing power from the solar. This is because of the truth that each water and electrical energy are incompressible. The web effectivity of the hydro-electric course of could be as excessive as 85 per cent. The preliminary outlay is usually nice, however the price of upkeep is small, and the comfort provided ideally suited. My alternating system is invariably employed, and to date about 7,000,000 horse-power have been developed. As usually used, we don’t get greater than six-hundredths of a horse-power per ton of coal per yr. This water power is subsequently equal to that obtainable from an annual provide of 120,000,000 tons of coal, which is about 25 per cent of the whole output in the USA. The estimate is conservative, and in view of the immense waste of coal 50 per cent could also be a better guess.

We get higher appreciation of the large worth of this energy in our financial improvement once we keep in mind that, in contrast to gasoline, which calls for a horrible sacrifice of human power and is consumed, it’s provided with out effort and destruction of fabric and equals the mechanical efficiency of 150,000,000 men�one and one-half occasions the whole inhabitants of this nation. These figures are imposing; however, we’ve got solely begun the exploitation of this huge nationwide useful resource.

There are two chief limitations at present�one within the availability of the power, the opposite in its transmission to distance. The theoretical energy of the falling water is gigantic. If we assume for the rain clouds a mean peak of 15,000 ft and annual precipitation of 33 inches, the 24 horse-power per sq. mile is over 4000, and for the entire space in america greater than 12,000,000,000 horse-power. As a matter of reality, the bigger portion of the potential power is used up in air friction. This, whereas disappointing to the economist, is a lucky circumstance, for in any other case the drops would attain the bottom with a velocity of 800 ft per second�sufficient to boost blisters on our our bodies, whereas hail can be positively lethal. A lot of the water, which is obtainable for energy functions comes from a peak of about 2000 ft and represents over one and one-half billion horse-power, however we’re solely in a position to make use of a mean fall of, say, 100 ft, which signifies that if all of the water-power on this nation have been harnessed beneath the prevailing circumstances solely 80,000,000 horse-power could possibly be obtained.

THE NEXT GREAT ACHIEVEMENT� ELECTRICAL CONTROL OF ATMOSPHERIC MOISTURE

However the time could be very close to when we will have the precipitation of the moisture of the environment underneath full management, after which it is going to be potential to attract limitless portions of water from the oceans, develop any desired quantity of power, and utterly rework the globe by irrigation and intensive farming. A higher achievement of man by way of the medium of electrical energy can hardly be imagined.

The current limitations within the transmission of energy to distance shall be overcome in two ways�through the adoption of underground conductors insulated by energy, and thru the introduction of the wi-fi artwork. The primary plan I’ve superior years in the past. The underlying precept is to convey by means of a tubular conductor hydrogen at a really low temperature, freeze the encompassing materials and thus safe an ideal insulation by oblique use of electrical power. On this method the facility derived from falls could be transmitted to distances of tons of of miles with the very best financial system and at a small value. This innovation is certain to enormously prolong the fields of electrical software. As to the wi-fi technique, we’ve got now the means for financial transmission of power in any desired quantity and to distances solely restricted by the size of this planet. In view of assertions of some misinformed specialists to the impact that within the wi-fi system I’ve perfected the facility of the transmitter is dissipated in all instructions, I want to be emphatic in my assertion that such isn’t the case. The power goes solely to the place the place it’s wanted and to no different.

When these superior concepts are virtually realized we will get the complete advantage of water-power, and it’ll turn out to be our chief dependence within the provide of electrical energy for home, public and different makes use of within the arts of peace and struggle.

ECONOMY IN LIGHT AND POWER� ELECTRIC PROPULSION

Within the nice departments of electrical mild and energy immense alternatives are provided by means of the introduction of all types of novel units which may be hooked up to the circuits at handy hours for the aim of equalizing the hundreds and growing the revenues from the crops. I’ve myself information of a variety of new home equipment of this type. An important amongst them might be an electrical ice machine which obviates solely using harmful and in any other case objectionable chemical compounds. The brand new machine will even require completely no consideration and might be extraordinarily economical in operation, in order that the refrigeration can be effected very cheaply and conveniently in each family.

An fascinating fountain, electrically operated, has been introduced out which is more likely to be extensively launched, and can afford an uncommon and pleasing sight in squares, parks, lodges and residences.

Cooking units for all home purposed are being supplies, and there’s nice demand for sensible designs and recommendations on this subject. The identical could also be said of electrical indicators and different engaging technique of promoting which could be electrically operated. A few of the results which it’s attainable to supply by electrical currents are fantastic and lend themselves to exhibitions, and there’s no doubt that a lot could be finished in that course. Theaters, public halls and personal dwellings are in want of an excellent many units and devices for comfort and supply ample alternatives to an ingenious and sensible inventor.

An enormous and completely untouched subject is using electrical energy for the propulsion of ships. The main electrical firm on this nation has simply outfitted a big vessel with high-speed generators and electrical motors and has achieved a sign success. Purposes of this type will multiply at a speedy fee, for some great benefits of the electrical drive at the moment are patent to everyone. On this connection gyroscopic equipment will in all probability play an necessary half, as its common adoption on vessels is certain to return. Little or no has but been finished within the introduction of electrical drive within the numerous branches of business and manufacture, and the prospects are limitless.

A FEW OF THE WONDERS TO COME

Books have already been written on the agricultural makes use of of electrical energy, however the reality is that hardly something has been virtually executed. The useful results of electrical energy of excessive pressure have been unmistakably established, and a revolution can be caused by way of the in depth adoption of agricultural electrical equipment. The safeguarding of forests towards fires, the destruction of microbes, bugs and rodents will, sooner or later, be completed by electrical means.

Within the close to future we will see a terrific many new makes use of of electrical energy aiming at security, notably vessels at sea. We will have electrical devices for stopping collisions, and we will even be capable of disperse fogs by electrical pressure and highly effective and penetrative rays. I’m hopeful that inside the subsequent few years wi-fi crops shall be put in for the aim of illuminating the oceans. The undertaking is completely possible, and if carried out will contribute greater than some other provision to the security of property and human lives at sea. The identical plant might additionally produce stationary electrical waves and allow vessels to get at any time correct bearings and different useful sensible knowledge with out resorting to the current means. It may be used for time signaling and lots of different functions of comparable nature.

Electrotherapy is one other nice area during which there are limitless prospects for electrical purposes. Excessive-frequency currents particularly have an ideal future. The time will come when this type of electrical power shall be out there in each personal residence. I contemplate it fairly potential that by means of their floor actions we might get rid of the customary tub, because the cleansing of the physique might be instantaneously effected just by connecting it to a supply of currents or electrical power of very excessive potential, which leads to the throwing off of mud or any small particles adhering to the pores and skin. Such a dry tub, in addition to being handy and time-saving, would even be of useful therapeutic affect. New electrical units to be used of the deaf and blind are coming and will probably be a blessing to the bothered.

Within the prevention of crime electrical devices will quickly develop into an necessary issue. In courtroom proceedings electrical proof will typically be decisive. In a time not distant it is going to be attainable to flash any picture shaped in thought on a display and render it seen at anywhere desired. The perfection of this implies of studying thought will create a revolution for the higher in all our social relations. Sadly, it’s true, that crafty lawbreakers will avail themselves of such benefits to additional their nefarious enterprise.

TELEGRAPHIC PHOTOGRAPHY AND OTHER ADVANCES

Nice enhancements are nonetheless attainable in telegraphy and telephony. Using a brand new receiving gadget which can be shortly described, and the sensitiveness of which might be elevated virtually with out restrict, will allow telephoning by means of aerial strains or cables nevertheless lengthy by decreasing the required working present to an infinitesimal worth. This invention will dispense with the need of resorting to costly constructions, which, nevertheless, are of circumscribed usefulness. It should additionally enormously prolong the wi-fi transmission of intelligence in all its departments.

The subsequent artwork to be inaugurated is that of image transmission by bizarre telegraphic strategies and present equipment. This concept of telegraphing or telephoning footage is previous, however sensible difficulties have hampered business realizations. Various enhancements of nice promise have been made, and there’s each purpose to anticipate that success will quickly be achieved.

One other invaluable novelty will probably be a typewriter electrically operated by the human voice. This advance will fill a long-felt need, as it should eliminate the operator and save quite a lot of labor and time in workplaces.

A brand new and very simple electrical tachometer is being ready for the market, and it’s anticipated that it’ll show helpful in energy crops and central stations, on boats, locomotives and cars.

Many municipal enhancements based mostly on using electrical energy are about to be launched. We’ve quickly to have in all places smoke annihilators, mud absorbers, ozonizers, sterilizers of water, air, meals and clothes, and accident preventers on streets, elevated roads and in subways. It should turn out to be subsequent to inconceivable to contract illness germs or get harm within the metropolis, and nation people will received to city to relaxation and get nicely.

ELECTRIC INVENTIONS IN WAR

The current worldwide battle is a strong stimulus to invention of units and implements of warfare. An electrical gun will quickly be introduced out. The marvel is that it was not produced way back. Dirigibles and aeroplanes will probably be outfitted with small electrical turbines of excessive rigidity, from which the lethal currents can be conveyed via the wires to the bottom. Battleships and submarines might be supplied with electrical and magnetic feelers so delicate that the strategy of any physique underwater or in darkness shall be detected. Torpedoes and floating mines are virtually in sight which can direct themselves mechanically and with out fail get in deadly contact with the item to be destroyed. The artwork of telautomatics, or wi-fi management of automated machines at a distance, will play an important half in future wars and, probably, within the subsequent phases of the current one. Such contrivances which act as if endowed with intelligence will probably be utilized in innumerable methods for assault in addition to protection. They could take the form of aeroplanes, balloons, cars, floor or under-water boats, or some other type in response to the requirement in every particular case and can be of higher vary and destructiveness than the implements now employed. I consider that the telautomatic aerial torpedo will make the massive siege gun, on which a lot dependence is positioned at current, out of date.

A quantity may be full of such strategies with out exhausting the chances. The advance even underneath the circumstances present is speedy sufficient, however when the wi-fi transmission of power for basic use turns into a sensible reality the human progress will assume the character of a hurricane. So all-surpassing is the significance of this marvelous artwork to the longer term existence and welfare of the human race that each enlightened individual ought to have a transparent concept of the chief elements bearing on its improvement.

THE POWER OF THE FUTURE

We’ve at our disposal three important sources of life-sustaining energy�fuel, water-power and the warmth of the solar’s rays. Engineers typically converse of harnessing the tides, however the discouraging fact is that the tidewater over one acre of floor will, on the typical, develop just one horse-power. Hundreds of mechanics and inventors have spent their greatest efforts in making an attempt to good wave motors, not realizing that the facility so obtained might by no means compete with that derived from different sources. The pressure of wind gives a lot better possibilities and is effective in particular situations, however is by far insufficient. Furthermore, the tides, waves and winds furnish solely periodic and sometimes unsure energy and necessitate the employment of huge and costly storage crops. In fact, there are different prospects, however they’re distant, and we should rely upon the primary of three assets. If we use gasoline to get our energy, we live on our capital and exhausting it quickly. This technique is barbarous and wantonly wasteful, and should be stopped within the curiosity of coming generations.

The warmth of the solar’s rays represents an immense quantity of power vastly in extra of water-power. The earth receives an equal of 83 foot-pounds per second for every sq. foot on which the rays fall perpendicularly. From easy geometrical guidelines making use of to a spherical physique it follows that the imply price per sq. foot of the earth’s floor is one-quarter of that, or 20 three/four foot-pounds. That is to say over a million horse-power per sq. mile, or 250 occasions the water-power for a similar space. However that’s solely true in concept; the sensible information put this in a special facet. For example, contemplating the USA, and considering the imply latitude, the day by day variation, the diurnal modifications, the differences due to the season and informal modifications, this energy of the solar’s rays reduces to about one-tenth, or 100,00 horse-power per sq. mile, of which we’d have the ability to get well in high-speed low-pressure generators 10,000 horse-power. To do that would imply the installment of equipment and storage crops so giant and costly that such a challenge is past the pale of the sensible. The inevitable conclusion is that water-power is by far our most respected useful resource.

On this humanity should construct its hopes for the longer term. With its full improvement and an ideal system of wi-fi transmission of the power to any distance man will have the ability to clear up all the issues of fabric existence. Distance, which is the chief obstacle to human progress, shall be utterly annihilated in thought, phrase and motion. Humanity can be united, wars might be made unattainable and peace will reign supreme.
