This PESWiki page is the primary home page for the H2earth Institute's project to build, test, and demonstrate a "Geovoltaic Energy Pump" for practical home power applications, based on the Tesla Switch. All aspects of this design are derived from public domain technology, including items which were the subject of U.S. and foreign PCT patents which are now expired,technologies which were originally published instead of being patented, and design constructs which were originally disclosed more than 20 years ago, which, even if patented, have long since passed into the public domain. Due credit and appreciation is herby given to PowerPedia:Nikola Tesla, Ron Brandt, Joseph Newman, Ron Cole, PowerPedia:John Bedini, PowerPedia:Tom Bearden, Directory:Peter Lindemann, and Patrick Kelly for their respective contributions to this configuration. The sponsors of this project pledge to implement the There was an error working with the wiki: Code[2] with respect to any commercial ventures which evolve from the effort to utilize this technology, and request that any unaffiliated products derived from this design be developed under similar arrangements.


Tesla understood that the resistance of lines or components, viewed from the dynamo end, seemed to be an impossible “barrier? for charge carriers to penetrate. This barrier caused the “bunching? effect. Electrostatic charges were literally stopped and held for an instant by line resistance, a barrier which only existed during the brief millisecond interval in which the power switch was closed. The sudden force application against this virtual barrier squeezed charge into a density impossible to obtain with ordinary capacitors. It was the brief application of power, the impact of the charge against the resistance barrier, which brought this abnormal electro-densified condition. -- Gerry Vassilatos, Secrets of Cold War Technology as quoted in The Free Energy Secrets of Cold Electricity by Directory:Peter Lindemann

The Tesla Switch apparently made its first public appearance of the modern era in the early 1980s, in a unit the size of a cigar box, demonstrated by Ron Brandt, who was said to have worked for Nicola Tesla many years before, in his youth. Brandt was reputed to operate an electric car with the Switch, without external recharging, exactly as Tesla himself is said to have done. Brandt reportedly claimed no proprietary ownership of the technology, saying it was a Tesla invention which was never patented. Other instances of this [configuration] apparently exist historically, as well. Brought to the attention of John Bedini, a Tesla Switch based on Brandt's schematic was rigorously tested by Bedini in 1984, the There was an error working with the wiki: Code[3] later that year by Mike Mueller for the Tesla Book Company. In 1995, Tom Bearden published a paper entitled, Bedini's Method for Forming Negative Resistors in Batteries This paper elaborated on the theory of the technique, but is a dense read and contained no illustrations consequently, it did not gain the recognition for the effect nor inspire its use in the way that it otherwise might have. Five years later, John Bedini would file the first of several patents for related battery charging devices, based on proprietary magnet/coil configurations.

However, on July 27, 2007, the Practical Guide to Free Energy Devices (Patrick Kelly, Editor) released an updated document, which newly [outlined and illustrated] the Tesla Switch in a clear and concise way as never before, bringing practical design information that had been obscured in other writings on the subject for at least 25 years. To a global team of 65 research associates in 16 countries collaborating in realtime on deciphering Stan Meyer's Water Fuel Cell, this proved to be the Rosetta Stone.

Upon investigation, it became apparent that the switched potential function of the device, in which Voltage translates instantaneously, but the flow of Current is slower to propagate, and is interrupted by the Switch before a closed circuit is actually in effect, 'is the single mechanism common to all legitimate FE/OU electromagnetic devices, of every description', from Coler (1945) to Stoern (2007) - including the Water Fuel Cell - and likely many prior to that as well. The underlying switch dynamic is one articulated by Tesla in a variety of writings and patents throughout his career. Supported by analysis of the Gray Tube by Bedini and Lindemann, and of the energy yield from Spark Gap Discharges by Aleck, and other sources, the switch itself was rapidly realized to be the key everyone has been looking for all these years. All of the rotating machinery, the coils and magnets, armatures and flywheels and counterweights, are all bit players in the drama the switched potential is the star of the show. It is where the free energy (known as "Radiant Energy" by Tesla, "Quantum Vacuum Energy" by Bearden, and "Zero-Point Energy" to most of the FE/OU Movement) is entrained, captured or otherwise somehow originally manifest the permanent magnets and coils of wire are simply ways of amplifying and manipulating this energy. Failure to recognize this fact is why no FE/OU device has become practical until now.



The GVEP consists of a Tesla Switch utilizing a rotary mechanical contactor in lieu of solid state components to control cross charging among a standard residential battery bank of 12v lead-acid deep cycle batteries, arranged in groups of four. An enhanced version of the Energy Machine of Joseph Newman, herein, the "Newmach Module(s)", is/are used to drive the rotary mechanism, with the Newman Commutator and Tesla Switch sharing a common contactor disk assembly. This choice not only provides a suitable motor to rotate the disk which consumes virtually no power to drive it (nanoamps), but also contributes a positive back pulse of high voltage at the switching frequencies of the battery array, which is additive to the overall energy balance of the system. Unlike other possible drivers for a rotary contactor, the Newmach Modules can be made compact, with a minimum of moving parts, are not encumbered by patent rights (disclosed and published in-depth in 1984, its 1983 PCT patent expiring in 2000), and can be substantially improved over its nominal observed and replicated level of performance.

Driver Mechanism

Based on Joseph Newman's expired 1983 PTC Patent WO8300963 (Figure 6), the proposed Newman Modules are enhanced over the stock Newman design in four important ways. [1] A new generation of Neodymium-Iron-Born (NdFeB) magnets are to be utilized, [N-50 Class, Ni-Cu-Ni clad, Remanance 1400 - 1450 (BrmT), Max. Energy Product 48 - 51 (BH)max(MGO), Coercive Force ?10.0 Hcb (KOe), Intrinsic Coercive Force ?11 Hci (KOe), as described in the paper Motor Design Advancements Using NdFeB Magnets [2] In the book "There was an error working with the wiki: Code[4]" by D.A. Kelly (1991), Electrodyne Corporation reports that Tinned Copper Wire produces a 3x improvement in magnetic field strength when used in Newman coils, over regular copper wire. [3] A ferric steel keeper will be employed, to concentrate magnetic flux, resulting in a 3x performance improvement, as demonstrated by Lindemann in the lecture ["Electric Motor Secrets"]. [4] The use of Bifilar wire will increase the energy release per pulse by a factor of 250,000x, as per Tesla U.S. Patent 512,340. While Newman has spent the past decade re-engineering his system to reduce the Back EMF negative current spikes in favor of more mechanical energy, resulting in a completely different machine configuration, the Institute believes that his device was far more valuable in its original embodiment, when in a context which permits those spikes to be properly utilized, as presented here.

While a large Newman Energy Machine, which itself puts out all of the power necessary for an average home, will generate back spikes so powerful that they will destroy conventional batteries, when integrated as the driver mechanism for a Tesla Switch, and scaled down to simply drive the rotary switch mechanism, the spikes are of a reasonable magnitude which complements the self--charging operation of the battery array. Moreover, these "negative current" pulses (which are actually positive {+} polarity, or rather, a 'current of holes'), must be matched with an electron source in order to generate the conventional current flow that provide a useful charge to the battery bank. In the GVEP, much smaller Newman devices are used, which are far more efficient, and are properly integrated with home-scale battery infrastructure.

Tesla Switch

The Tesla Switch creates a pulsed current flow between four 12v, Lead-acid batteries in an array (in the anticipated system, three such arrays operate together, or 12 batteries in all). Through some mechanism of radiant energy entrainment, net energy is captured within the battery system in this process. The rate of entrainment charging adjusts itself to the external load being drawn from the batteries the greater the discharge to load, the faster external energy is captured from the active vacuum. The switching rate also determines the rate of charge, and must be kept in a range (20cps to 800cps, TBD) which, in relation to the [then] load, does not damage the batteries from excessive charge.

Those who have been involved with FE/OU experiments have consistently reported that in various radiant energy devices, electromechanical switching yields superior results to solid state electronics. When using solid state components, PNP transistors are widely preferred over NPN transistors, however, the reason for this has only recently become apparent: atmospheric electrons from the local environment can enter the circuit in a PNP device, but not through an NPN. A picture emerges that radiant currents do not behave in the same manner as electron currents. Dr. Lindemann recommends beginning with mechanical contactors to eliminate sources of error, before taking a FE/OU system to a solid state architecture. In the documentary "Energy from the Vacuum", Part 2, Bedini himself features a "transistor-free" version of his motor, which is the one he says 'will run forever', while Stan Meyer filed U.S. Patent 4,613,779, on an Electric Pulse Generator to be used with his Water Fuel Cell, with the following Background:

"Power supplies for electrical systems have been utilized for a century or so. As time progressed new uses of electrical systems placed a need for more sophisticated systems. One particular utilization is the need for power transfer to the utilization device but yet with the requirement that there be power isolation. The advancement of electronics and power devices such as SCRs, Triacs and the such, appeared to be an obvious solution to such a power transfer. Current limiting circuits also were developed. Unfortunately, the solution was not met. The electronic devices in most instances could not limit or tolerate high power. Finally, it became apparent that the electrical systems, with this type of current limiting requirement necessitated electrical power supplies--not electronic."

Current Source

A limitation inherent in most FE/OU devices is that the radiant energy extracted from the quantum vacuum ("ZPE") comes in the form of potential, and while this can flow as a 'radiant current', is not sensible as an electron current with ammeter instrumentation. If the system does not carefully match this potential to an 'electron source', high potential will build, which destroys batteries and blows capacitors, rather than charging them. Failure to account for this stumbling block has been the Achilles' heel of many otherwise viable free energy devices. The H2earth Institute has determined, for example, that the Meyer Water Fuel Cell's Electron Extraction Circuit is actually an "Electron Donor" within the radiant FE/OU circuit that runs the device. Since the WFC itself, properly configured, consumes no current (it is a water capacitor that likes to be 'blown', repeatedly), the WFC/EEC can serve to provide current within an overall fixed-facilities, distributed generation context. However, because this raises issues - at the household level - of what to do with the large amounts of [then] surplus Hydroxy gas which would be produced, a residential radiant power system would best utilize environmental free electron sources, particularly Ground and Air. For this, the Tesla U.S. Patents 685,957 and 685,958 ("Apparatus" and "Method" for the Utilization of Radiant Energy) provide the ideal electron capture subsystem.

Balance-of-System Components

The objective of this project is to design/build/test a version of the Tesla Switch which can interoperate with the large range of commercial, off-the-shelf residential battery bank infrastructure which has hit the market in the past 15 years to accommodate the conventional Renewable Energy marketplace. Tens of thousands of homes now have 12v battery bank systems for home power, charged by Solar Photovoltaic panels, Wind Turbines, Micro-Hydro, and Biogas energy sources. The Battery Bank components, Automatic Transfer Switch (Grid-Inertia), Charge Controller, Voltage Regulator, Sine Wave Inverter, etc. are now all common consumer electronics available from multiple vendors online, and from local renewable energy installation contractors nationwide. If the GVEP can interface with a conventional residential battery bank package, it can reduce the cost of home power by 1 - 2 orders of magnitude vs. Solar PV, and put FE/OU into the marketplace as a practical alternative within 12 months.


We believe that local Renewable Energy Contractors are a pragmatic and innovative group of engineers, who will find a single FE/OU powered test house to be sufficiently persuasive to begin testing, using, selling, and installing the GVEP themselves in their local communities. Each working home power installation will then attract its own converts, as friends and neighbors of "early-adopters" also opt to become energy independent. Due to the electrical and mechanical simplicity of the unit, no significant investment is needed in fabrication or assembly to begin producing such systems. With no big factory, precision machine tooling, specialized manufacturing equipment, or venture capital necessary, and no issues as to intellectual property rights, the GVEP can be productized by dozens of independent small business startup ventures around the world simultaneously, and bootstrapped by each of them into substantial sales volumes.

Working hardware, locally demonstrated and available for immediate purchase and installation, trumps any skepticism that fundamentalist scientific dogma can throw at it. The fulcrum that gives a mainstream establishment leverage to intercept and block successful FE/OU technology has been - virtually always and everywhere - the point at which the Inventor Turns Entrepreneur. First, there are psycho-social factors common to talented research inventors, which reciprocally make them unlikely "people persons" to organize and lead venture teams (i.e. "they don't play well with others"). Invariably, Inventor ego, paranoia, greed, suspicion, and poor socialization/communications skills, or bad judgment (or bad luck) in finding/selecting potential partners and team members, inhibits successful commercialization of the completed technology. Second, however, when the development stage technology venture turns to venture capitalists and investment bankers to underwrite productization and manufacturing, these institutional investors always must obtain independent technical evaluations from respected mainstream academic university research professors. They must, for reasons of legal liability, conduct this "Due Diligence" investigation, soliciting the opinions of independent scientific sources. Of course, for reasons obvious, establishment scientists will - always and everywhere - fail to endorse FE/OU technology concepts, thus dissuading the venture capitalist or investment banker from backing the inventor's technology, product, and venture. The GVEP, requiring no such financial underwriting, and having no one aberrant inventor, can easily sidestep these impediments, sliding into the marketplace where no opposition can effectively prevent it.

Project Status

The GVEP has never been built before. It is a logical integration of complementary technologies, each of which has been independently demonstrated and is in the public domain. For various reasons which the different components exhibit, they all should fit together in a very organic, symbiotic manner.

The H2earth Institute has arranged for the promulgation of a comprehensive Engineering Package of detailed drawings and specifications from its volunteer Research Associates, which will include a set of electromechanical assembly drawings in AutoCAD, specific circuit schematics in pSpice, and 3-D modeling animation in Maya. This documentation is expected to be completed in the 4th Quarter 2007.

An Institute team in Central Florida, lead by a senior scientist (PhD in Atomic Physics, Pioneer in Electro-Optics and Lasers, Registered Professional Engineer in Electrical Engineering, Certified Manufacturing Engineer, Certified Environmental Engineer) and with the participation of several electrical and mechanical engineers and technicians, will assemble a prototype from the completed drawings package.

Two 'Residential Systems Testbeds' have been arranged, with test houses donated both on Florida's Space Coast and in the Tampa Bay area, at which full scale home power systems utilizing the GVEP and conventional battery banks will be installed for evaluation and demonstration purposes. Florida's well-established Renewable Energy industry, representing a wealth of experience in [Zero Energy Home] technologies will be treated to the first public demonstrations of the system, in early to mid-2008.


All technical information, design specifications, and test data will be posted here, as it is developed. The sponsors solicit drawings, interface suggestions, and replications worldwide. All technology and information is in the Public Domain, and the resulting unit may be freely manufactured, sold, or used by anyone, anywhere. It is hoped that a vibrant new home power industry will arise among competing vendors and different implementations of FE/OU technologies, spurring further discovery, innovation, and improvement.

Whether as a Do-It-Yourself project or a commercial system manufactured and installed for the end-use Homeowner on a 'turn-key' basis, a complete GVEP -based home power system is expected to cost approximately $5,000.US. The Balance-of-System components [apart from the GVEP] represent the bulk of that cost, and their prices are subject to market forces, declining with increasing competitive pressures and production volume.


The phrase "Geovoltaic Energy Pump" is an effort to normalize the concept to Bearden's Geothermal Heat Pump analogy for FE/OU systems, and the Solar Photovoltaic industry that it will leverage off of for the balance-of-system components.

Respected critics inside the FE field say that this is not a plausible design. The Tesla Switch (a misnomer) is difficult to control [ref: John Bedini attempts], and is not superior to other OU designs out there.
