En daar is Grayvox, mijn vader zij altijd vanwege mijn rode haar "Vossie", maar het is voor zover nog aanwezig is het grijs,vandaar Grayvox

Ik heb dus op een locatie eigenhandig een huisje gebouwd, waar wel water en riool is maar verder moet ik het doen met gas uit de fles (LPG) en een aggregaat dat ik tijdens het bouwen heb gebruikt voor de zware machines.

Om nu mijn koelkastje en radio en led-verlichting vanuit een een tweetal tractie-batterijen te voeden heb ik een aantal energiebronnen nodig om mijn accu's op peil te houden, die er dan wel zijn als ik ze nodig heb.
Voor een deel zou dat een tweetal zonnepanelen kunnen zijn of een zelfgebouwde windgenerator, maar er is vast meer mogelijk?

Vandaar mijn oproep aan allen, kom op en we gaan het maken en uitproberen.

Ja zo kunnen we elkaar helpen. En denk dat er toch vrij makkelijk een oplossing te bouwen moet zijn voor het geen Grayvox voor ogen heeft althans met een juist plan.

Doorbraak: waterstof uit zonlicht

Waterstof rechtstreeks produceren uit zonlicht kon tot nu toe alleen met het schaarse platina. Onderzoekers kunnen nu met een nieuw materiaal, bestaande uit het veel voorkomende molybdeen en zwavel, even hoge rendementen boeken. Komt de waterstofeconomie er nu dan toch aan?

Waterstof als oplossing energieopslagprobleem
Zonnepanelen zijn op dit moment de effectiefste manier om energie uit zonlicht op te wekken. Commerciële cellen halen tien tot twintig procent, het allerbeste laboratoriummodel zit tegen de veertig procent. Elektriciteit kent echter een vervelend probleem. Het is zeer lastig op te slaan. Dat is met waterstofgas makkelijker, zeker in grotere hoeveelheden. Daarom geloven veel onderzoekers in een waterstofeconomie, waarin energie over de wereld wordt getransporteerd in de vorm van waterstof.

Waterstof produceren uit zonlicht
Essentieel hierbij is het splitsen van water in waterstof en zuurstof. Dat kan door elektrische stroom door water te laten lopen. Hierbij wordt water gesplitst in waterstof en zuurstof. Een tweede methode is het verhitten van steenkool met waterdamp, waarbij kooldioxide en waterstofgas ontstaat. Uiteraard is de mooiste oplossing om water rechtstreeks te splitsen in waterstof en zuurstof met behulp van zonlicht. Tot nu toe was daar maar één effectieve methode voor waarbij het zeldzame edelmetaal platina als katalysator wordt gebruikt. Hierbij wordt meer dan 10% van alle zonlicht gebruikt om waterstof mee te produceren: het rendement van een goedkope zonnecel.

Afbeelding

Molybdeensulfide als zonnecel
Nu is een nieuwe methode ontwikkeld, waarbij molybdeensulfide wordt gebruikt. Chemische zonnecellen bestaan uit kleine staafjes, waarvan het bovenste deel blauw licht absorbeert en met behulp hiervan water splitst in H+-deeltjes (protonen) en zuurstof. In het onderste deel worden onder invloed van rood licht elektronen aan de H+-deeltjes toegevoegd en geoxideerd tot waterstofgas. Voor die tweede reactie werd tot nu toe platina gebruikt. De onderzoekers hebben nu ontdekt dat molybdeensulfide (Mo3S4) dit laatste proces even efficiënt uitvoert. Hierbij absorbeert een silicium P-halfgeleider (waaruit de staafjes bestaan) het rode licht en draagt de energie (en elektronen) over aan molybdeensulfide, dat de protonen met de elektronen samenvoegt en zo waterstofgas produceert.

De onderzoekers keken de kunst af van bacteriën. Ze stelden vast hoe bacteriën protonen in waterstofgas omzetten en wat deze reactie zo efficiënt maakte. Ze ontdekten toen dat dit effect met molybdeensulfide uitstekend te repliceren is.

Helaas is er nog steeds geen materiaal dat de eerste stap, het omzetten van water in protonen en zuurstof, efficiënt kan verrichten. De onderzoekers willen ook dit probleem op soortgelijke wijze aanpakken en op deze manier een even effectief materiaal ontdekken. Ook dit belooft een taaie klus te worden.

Doorbraak waterstofeconomie?
Lukt het deze onderzoekers (of hun collega’s) ook de laatste missende schakel te vinden en zo een effectief en goedkoop proces te ontwikkelen om waterstof te produceren, dan worden grote drijvende zonnefarms denkbaar, die in de wintermaanden de Noord-Europese landen van waterstofgas kunnen voorzien om zo de productie uit andere alternatieve bronnen aan te vullen. Dit zou effectief de energieafhankelijkheid van Europa terugbrengen tot nul.

Tesla's Fuelless Generator

In the 1880's, Nikola Tesla invented the alternating current system we use today. By the 1890's, he was working on a new type of electrical generator that would not "consume any fuel."

This paper documents where in his writings the description of this new generator is found, a theory of how a fuelless generator could work and a suggestion as to how Tesla's new device might have operated.

ABSTRACT

Ten years after patenting a successful method for producing alternating current, Nikola Tesla claimed the invention of an electrical generator that would not "consume any fuel." Such a generator would be its own prime mover. Two of Tesla's devices representing different stages in the development of such a generator are identified.

INTRODUCTION

While in college Nikola Tesla claimed it should be possible to operate an electrical motor without sparking brushes. He was told by the professor that such a motor would require perpetual motion and was therefore impossible. In the 1880's he patented the alternating current generator, motor, and transformer.

During the 1890's he intensively investigated other methods of power generation including a charged particle collector patented in 1901. When the New York Times in June of 1902 carried a story about an inventor who claimed an electrical generator not requiring a prime mover in the form of an external fuel supply, Tesla wrote a friend that he had already invented such a device.

Fuelless electrical generation raises the same objection of perpetual motion as did the generator in use today when it was first proposed. Research Nikola Tesla carried out during his second creative period and the resulting devices that were the basis for his assertion of fuelless electrical generation will be examined. Whether Tesla's fuelless generator was a "perpetual motion scheme" of the sort his teacher warned him against, or a creative application of recognized natural phenomena will be discussed.

TESLA'S STATEMENTS

In The Brooklyn Eagle, Tesla announced, on July 10th, 1931, that "I have harnessed the cosmic rays and caused them to operate a motive device." Later on in the same article he said that "More than 25 years ago I began my efforts to harness the cosmic rays and I can now state that I have succeeded." In 1933, he made the same assertion in an article for the New York American, November 1st, under the lead in "Device to Harness Cosmic Energy Claimed by Tesla." Here he said:

This new power for the driving of the world's machinery will be derived from the energy which operates the universe, the cosmic energy, whose central source for the earth is the sun and which is everywhere present in unlimited quantities.

Dating back "more than 25 years ago" from 1933 would mean that the device Tesla was speaking about must have been built before 1908. More precise information is available through his correspondence in the Columbia University Library's collection. Writing on June 10th, 1902 to his friend Robert U. Johnson, editor of Century Magazine, Tesla included a clipping from the previous day's New York Herald about a Clemente Figueras, a "woods and forest engineer" in Las Palmas, capital of the Canary Islands, who had invented a device for generating electricity without

burning fuel. What became of Figueras and his fuelless generator is not known, but this announcement in the paper prompted Tesla, in his letter to Johnson, to claim he had already developed such a device and had revealed the underlying physical laws.

IDENTIFYING THE INVENTION

The device that, at first, seems to best fit this description is found in Tesla's patent for an "Apparatus for the Utilization of Radiant Energy," number 685,957, that was filed for on March 21, 1901 and granted on November 5, 1901. The concept behind the older technical language is a simple one. An insulated metal plate is put as high as possible into the air. Another metal plate is put into the ground. A wire is run from the metal plate to one side of a capacitor and a second wire goes from the ground plate to the other side of the capacitor. Then:

Afbeelding

The sun, as well as other sources of radiant energy, throw off minute particles of matter positively electrified, which, impinging upon [the upper] plate, communicate continuously an electrical charge to the same. The opposite terminal of the condenser being connected to ground, which may be considered as a vast reservoir of negative electricity, a feeble current flows continuously into the condenser and inasmuch as the particles are ... charged to a very high potential, this charging of the condenser may continue, as I have actually observed, almost indefinitely, even to the point of rupturing the dielectric(1).

This seems like a very straightforward design and would seem to fulfill his claim for having developed a fuelless generator powered by cosmic rays, but in 1900 Tesla wrote what he considered his most important article in which he describes a self-activating machine that would draw power from the ambient medium, a fuelless generator, that is different from his Radiant Energy Device. Entitled "The Problem of Increasing Human Energy - Through the Use of the Sun," it was published by his friend Robert Johnson in The Century Illustrated Monthly Magazine for June 1900 soon after Tesla returned from Colorado Springs where he had carried out an intensive series of experiments from June 1899 until January of 1900.

The exact title of the chapter where he discusses this device is worth giving in its entirety:

A DEPARTURE FROM KNOWN METHODS - POSSIBILITY OF A "SELF ACTING" ENGINE OR MACHINE, INANIMATE, YET CAPABLE, LIKE AN LIVING BEING, OF DERIVING ENERGY FROM THE MEDIUM - THE IDEAL WAY OF OBTAINING MOTIVE POWER

Tesla stated he first started thinking about the idea when he read a statement by Lord Kelvin who said it was impossible to build a mechanism capable of abstracting heat from the surrounding medium and to operate by that heat. As a thought experiment Tesla envisioned a very long bundle of metal rods, extending from the earth to outer space. The earth is warmer than outer space so heat would be conducted up the bars along with an electric current. Then, all that would be needed is a very long power cord to connect the two ends of the metal bars to a motor. The motor would continue running until the earth was cooled to the temperature of outer space. "This would be an inanimate engine which, to all evidence, would be cooling a portion of the medium below the temperature of the surrounding, and operating by the heat abstracted(2)," that is, it would produce energy directly from the environment without "the consumption of any material."

Tesla goes on in the article to describe how he worked on the development of such an energy device, and here it takes a bit of detective work to focus on which of his inventions he meant. He wrote that he first started thinking about deriving energy directly from the environment when he was in Paris during 1883, but that he was unable to do much with the idea for several years due to the commercial introduction of his alternating current generators and motors. It was not "until 1889 when I again took up the idea of the self-acting machine(3)."

THE TURBINE

He quickly came to realize that an ordinary electrical machine, like his generator, would not be able to directly extract energy from the cosmos and turned his efforts to what he called a "turbine" design.

The best known turbine, that is, water pump, associated with Tesla is his patent for such a device, #1,061,206, which was filed for in 1909 and granted in 1913. The unique point about this water pump is that instead of using some form of paddle wheels inside a box to move the water, he discovered that more water could be moved faster by using a set of flat metal disks. The turbine is, in itself, fascinating and may yet prove to be another important overlooked invention, but what is of concern regarding the electrical design is the general shape of the turbine - metal disks turning inside a supporting box.

This same shape turns up in another patent, this one for a "Dynamo-Electric Machine." This patent was filed and granted in the same year that Tesla said he returned to work on the "self-activating" machine, in 1889. The dynamo consists of metal disks that are rotated between magnets to produce an electric current.

Afbeelding

Compared to his alternating current generator, this "dynamo" represents something of a curious throwback to the days of Faraday's early experiments with a copper disk and a magnet. Tesla makes some improvement over the Faraday setup by using magnets that completely cover the spinning metal disks and he also adds a flange to the outside of the disks so current can be taken off more easily - all of which makes for a better generator than Faraday's. On the surface, though, it is hard to see why Tesla patented such an anachronistic machine at this point in his work.

The next piece of the puzzle is found in an article Tesla wrote for The Electrical Engineer in 1891 entitled "Notes on a Unipolar Dynamo." Here Tesla presents an in-depth analysis of the Faraday disk generator, explains why it was an inefficient generator, describes his improved variations on the Faraday machine, and, at the bottom of the third page of the article, states that he has devised a generator in which "the current, once started, may then be sufficient to maintain itself and even increase in strength(4)." Then, at the close of the article, he states that "several machines ... were constructed by the writer two years ago ..."(5) Two years before the writing of that article was 1889. All the evidence points to the turbine-shaped Unipolar Dynamo as being Tesla's first design for a machine that can continue to produce electricity after being disconnected from an outside source of power.

SELF-SUSTAINING CURRENT

Before going into the details of this invention it would be worthwhile to have an idea of how any generator, even in theory, could be capable of producing a self-sustaining current. This has been clearly explained by Walter M. Elsasser in a Scientific American article (May 1958) titled "The Earth as a Dynamo."

Elsasser models the earth-dynamo, conveniently for this explanation, on the Faraday generator of a metal disk spinning over a bar magnet placed at the edge of the disk. He notes, also, that the bar magnet could be replaced by an electromagnet which could get its power from the spinning disk by attaching one end of the electromagnet's wire to the outside of the disk and the other end of the wire to the metal rod running through the center of the disk.

Elsasser then points out that an ordinary disk generator "could not maintain a current for very long because the current induced in the disk is so weak that it would soon be dissipated by the resistance of the conductor [the disk]." This conventional arrangement would not be an answer to "how currents could be built up and perpetuated to maintain the earth's magnetic field." He does, though, propose three options in the dynamo model that would explain the earth's persistent magnetism.

If we had a material that could conduct electricity a thousand times better than copper, the system would indeed yield a self-sustaining current. We could also make it work by spinning the disk very fast... a third way we could make such a dynamo self-sustaining ... is to increase the size of the system: theory says that the bigger we make such a dynamo, the better it will function. If we could build a coil-and-disk apparatus of this kind of scale of many miles, we would have no difficulty in making the currents self-sustaining(6).

Tesla did not have a material a thousand times more conductive than copper, neither was he able to spin a disk at the ultra-high speeds needed to produce such a current, nor did he plan on using a piece of rotating metal several miles in diameter. What he did was to use energy that is usually wasted in a generator and turn it into a source of power.

UNIPOLAR DYNAMO

Tesla's design varied from that of Faraday in two major ways. First, he used a magnet that was bigger in diameter than the disk so that the magnet completely covered the disk. Second, he divided the disk into sections with spiral curves radiating out from the center to the outside edge.

Etc. Etc.
