A far better way, however, to obtain power would be to avail ourselves of the sun's rays, which beat the earth incessantly and supply energy at a maximum rate of over four million horsepower per square mile. Although the average energy received per square mile in any locality during the year is only a small fraction of that amount, yet an inexhaustible source of power would be opened up by the discovery of some efficient method of utilizing the energy of the rays. The only rational way known to me at the time when I began the study of this subject was to employ some kind of heat- or thermodynamic-engine, driven by a volatile fluid evaporate in a boiler by the heat of the rays. But closer investigation of this method, and calculation, showed that, notwithstanding the apparently vast amount of energy received from the sun's rays, only a small fraction of that energy could be actually utilized in this manner. Furthermore, the energy supplied through the sun's radiations is periodical, and the same limitations as in the use of the windmill I found to exist here also. After a long study of this mode of obtaining motive power from the sun, taking into account the necessarily large bulk of the boiler, the low efficiency of the heat-engine, the additional cost of storing the energy and other drawbacks, I came to the conclusion that the "solar engine," a few instances excepted, could not be industrially exploited with success. Another way of getting motive power from the medium without consuming any material would be to utilize the heat contained in the earth, the water, or the air for driving an engine. It is a well-known fact that the interior portions of the globe are very hot, the temperature rising, as observations show, with the approach to the center at the rate of approximately 1 degree C. for every hundred feet of depth. The difficulties of sinking shafts and placing boilers at depths of, say, twelve thousand feet, corresponding to an increase in temperature of about 120 degrees C., are not insuperable, and we could certainly avail ourselves in this way of the internal heat of the globe. In fact, it would not be necessary to go to any depth at all in order to derive energy from the stored terrestrial heat. The superficial layers of the earth and the air strata close to the same are at a temperature sufficiently high to evaporate some extremely volatile substances, which we might use in our boilers instead of water. There is no doubt that a vessel might be propelled on the ocean by an engine driven by such a volatile fluid, no other energy being used but the heat abstracted from the water. But the amount of power which could be obtained in this manner would be, without further provision, very small. Electricity produced by natural causes is another source of energy which might be rendered available. Lightning discharges involve great amounts of electrical energy, which we could utilize by transforming and storing it. Some years ago I made known a method of electrical transformation which renders the first part of this task easy, but the storing of the energy of lightning discharges will be difficult to accomplish. It is well known, furthermore, that electric currents circulate constantly through the earth, and that there exists between the earth and any air stratum a difference of electrical pressure, which varies in proportion to the height.

We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature’s inexhaustible sources of energy — sun, wind and tide. I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.

Electricity is really just organized lightning

It is probable that we shall soon have a self-acting heat-engine capable of deriving moderate amounts of energy from the ambient medium. There is also a possibility�though a small one�that we may obtain electrical energy direct from the sun. This might be the case if the Maxwellian theory is true, according to which electrical vibrations of all rates should emanate from the sun. I am still investigating this subject. Sir William Crookes has shown in his beautiful invention known as the "radiometer" that rays may produce by impact a mechanical effect, and this may lead to some important revelation as to the utilization of the sun's rays in novel ways. Other sources of energy may be opened up, and new methods of deriving energy from the sun discovered, but none of these or similar achievements would equal in importance the transmission of power to any distance through the medium. I can conceive of no technical advance which would tend to unite the various elements of humanity more effectively than this one, or of one which would more add to and more economize human energy. It would be the best means of increasing the force accelerating the human mass. The mere moral influence of such a radical departure would be incalculable. On the other hand if at any point of the globe energy can be obtained in limited quantities from the ambient medium by means of a self-acting heat-engine or otherwise, the conditions will remain the same as before. Human performance will be increased, but men will remain strangers as they were.

They are developing a form of renewable energy that runs on hubris.

Power corrupts, but we want energy.

One day, as I was roaming the mountains, I sought shelter from an approaching storm. The sky became overhung with heavy clouds, but somehow the rain was delayed until, all of a sudden, there was a lightening flash and a few moments after, a deluge. This observation set me thinking. It was manifest that the two phenomena were closely related, as cause and effect, and a little reflection led me to the conclusion that the electrical energy involved in the precipitation of the water was inconsiderable, the function of the lightening being much like that of a sensitive trigger. Here was a stupendous possibility of achievement. If we could produce electric effects of the required quality, this whole planet and the conditions of existence on it could be transformed. The sun raises the water of the oceans and winds drive it to distant regions where it remains in a state of most delicate balance. If it were in our power to upset it when and wherever desired, this might life sustaining stream could be at will controlled. We could irrigate arid deserts, create lakes and rivers, and provide motive power in unlimited amounts. This would be the most efficient way of harnessing the sun to the uses of man. The consummation depended on our ability to develop electric forces of the order of those in nature.

Three hundred years ago it would have seemed absurd to say that this black mineral, this sea-coal, which could be used as a substitute for wood to burn in one's grate, could be applied to revolutionize human affairs. Today we know that there is another source of energy a million times greater. We have not yet learned how to harness it or apply it, but it is there. Occasionally in complicated processes in the laboratory a scientist observes transmutations, re-arrangements in the core of the atom, which is known as the nucleus, which generate power at a rate hundreds of thousands of times greater than is produced when coal is burned and when, as the scientists put it, a carbon atom satisfied its affinity for an oxygen molecule. It can scarcely be doubted that a way to induce and control these effects can be found. The new fire is laid, but the particular kind of match is missing.

Power can be safely exercised only in the service of that which is ostensibly good. Power is like gasoline. Spread aimlessly over the landscape, it can result in an inferno, causing untold harm. Correctly contained, it can cook supper or transport us to Boston.

Worse yet, he still had to remind himself that sensations—such as tonight’s skin-cooling sea breeze—were just a blizzard of electric impulses, tricking his brain, his nerves.
Which, he had begun to fear, might not just be the endgame for Dornaani civilization. It could be in humanity’s future as well. Conceivably, those seeds were latent in electricity itself. Given how it ultimately expanded each individual’s sphere of contact and control, its utility was inseparable from the allure of its power. We summon heat and light without having to create it ourselves. We communicate across continents and oceans. We operate machines that labor in our stead. We keep opponents at a safe distance with remote sensors and drones. Is that how the long, subtle slide into speciate senescence began, that the more a species distanced itself from direct action, the more unfamiliar the natural environment became?

Conceptually, we would like a `Maxwell's demon' to exist within the power grid capable of capturing the geomagnetic storm energy. This could someday be a new feature of the `smart grid.'

Young Daniel Shipstone saw at once that the problem was not a shortage of energy but lay in the transporting of energy. Energy is everywhere—in sunlight, in wind, in mountain streams, in temperature gradients of all sorts wherever found, in coal, in fossil oil, in radioactive ores, in green growing things. Especially in ocean depths and in outer space energy is free for the taking in amounts lavish beyond all human comprehension.
Those who spoke of “energy scarcity” and of “conserving energy” simply did not understand the situation. The sky was “raining soup”; what was needed was a bucket in which to carry it.

[F]our hundred years hence the power question in England may be solved somewhat as follows: The country will be covered with rows of metallic windmills working electric motors [generators] which in their turn supply current at a very high voltage to great electric mains. At suitable distances, there will be great power stations where during windy weather the surplus power will be used for the electrolytic decomposition of water into oxygen and hydrogen. ...In times of calm, the gasses will be recombined in explosion motors working dynamos which produce electrical energy once more, or more probably in oxidation cells.

If you could invent a better battery, one that can store more energy using less exotic metal, one that could handle the heat without loss of performance or just plain catching on fire, we could store energy from the wind and the Sun and have it available whenever we need it. You would change the world all right. You might also get rich – crazy rich!
