Transforming Energy for All Humanity

Pioneering at the Frontier of Fusion Physics



We have designed and tested a compact aneutronic fusion reactor capable of delivering tens of kilowatts of power, yet scalable to megawatts. It can deliver constant, distributed energy, anywhere, anytime, without generating greenhouse gases or other waste products, or requiring expensive capital infrastructure or exotic materials, or even any oxygen or solar energy to operate.


Our electric fusion devices are portable, safe, and inexpensive to manufacture. Our patent-pending embodiments create a globally transformative change to all energy production with a dramatic reduction in carbon emissions. The technology heralds a monstrous leap in clean energy technology, not an incremental improvement to existing technology.

Fusion benchtop lithium proton



Our electric fusion reactor design has multiple safety systems and produces no neutrons, or ionizing radiation, hence no radioactive waste.


A near carbon-neutral energy source that reduces dependency on fossil fuels. The technology heralds a monstrous leap in clean energy technology, not an incremental improvement to existing technology.


Our devices can be mass-produced inexpensively using known engineering methods and can be scaled to yield more energy with larger units.



Our goal is to transform energy production into fusion. With a specific ten-year objective to convert most fossils-use to electric fusion. Our strategy is to prove, demonstrate, and validate the technology with the scientific community and to license the intellectual property to strategic verticals and industries to accelerate global adoption.



We seek $10 million of funding to enable us to complete our research and development and to engineer and market well-designed products. With these funds, we plan to build application-specific demonstration products that prove commercial viability.



Today, the founders have built a series of laboratory experiments that show fusion reactions. This is confirmed via neutron instrumentation, gamma-ray, and optical spectroscopy data that substantiate fusion reactions. Also, two prototype electrical power generating devices have been built and are in the testing and refinement stage.



Based on the R&D data we will refine three application-specific designs at different power scales, initially targeted at 10 kilowatts, 500 kilowatts, and one megawatt. These units will be placed with key customers or strategic partners for further integration in their specialized commercial markets.



With feedback from beta testing, we will refine the engineering of our design approaches to maximize energy harvest and minimize production costs. Designs and technical design guidelines will be prepared to support licensees of the technology to strategic production and integration partners for a variety of applications and markets.






EFS was founded in 2020 by Ken E. Kopp and Ryan S. Wood to advance a breakthrough approach to safe, scalable, cost-effective fusion power with a very low cost of energy, small form-factor, and clean environmental profile. With our patent-pending approach, EFS is poised to deliver a transformational energy source capable of supporting the planet for centuries. EFS is based in Colorado and is using our proprietary science insights and engineering towards a global transformation for all humanity.


What differentiates EFS from other fusion efforts?

Fusion efforts have failed to deliver on their promise. Over $50 billion has been spent and there are no reactors producing electricity. These scientific approaches, no matter how sophisticated by some of the brightest minds in the world, have all failed and the promise is always “ten years off”.

It is time for a new approach, EFS has the problem solved – aneutronic fusion with lithium + proton = helium + energy converted directly to useable electricity. EFS is pioneering this revolutionary energy technology, using a novel fusion physics that does not emit dangerous radiation. The founders have found an easier and safer way to generate fusion chain reactions. We use a cyclical process that cycles into and out of fusion in a plasma with electrical arcing, a magnetic induction field, and pressure confinement. Think of it as an electrical arc, passing through a dense plasma fuel, with pressure confinement. In short, a sort of fusion-plasma “transformer”.  One of the keys is our unique fuel that creates a super dense plasma ten orders of magnitude denser than historically failed approaches.


Why is proton-lithium fusion the preferred pathway?

The lithium-proton fusion reaction is preferred because it generates virtually no neutrons (thereby supporting aneutronic fusion) or radiation and has strong energy output. A proton is a hydrogen atom stripped of its electron; lithium (Li) is a light, non-radioactive element that is used in lithium-ion batteries and many other industrial applications. Hydrogen-lithium represents a clean, and abundant fusion fuel cycle making it the ideal fuel source for EFS’s commercial fusion solution.


How does EFS’s approach achieve practical fusion?

The standard of fusion system performance is the Lawson Criterion. The Lawson criterionis a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment. The criterion consists of three basic elements: density, temperature, and time. These elements are used to calculate a value known as the “Triple Product”

EFS’s LEEF Triple Product is favorable for the follow reasons:

  1. EFS’s LEEF fuel operates in a supercritical fluid state with a density orders of magnitude higher than any other known approach. LEEF densities are literally off the chart used to document the plethora other approaches.
  2. Ion temperatures orders of magnitude higher and measured in MEV as opposed to KEV seen in other approaches result in significant chain reactions during every fusion cycle. Again, LEEF energies are literally off the chart.
  3. In other approaches stability of magnetic confinement is the primary driver of the confinement & Fusion burn time. This has been a failure point for other approaches. The LEEF process is cyclical and fusion EMF energy is extracted every cycle via magnetic induction at very high efficiencies exceeding 90% as compared to the ~30% seen in “heat” based extraction used in other approaches. Our induction field by nature is not a steady state field nor should it be lest we suffer the same issues plaguing other programs.
  4. In a preignition state our fuel exhibits a modified coulomb barrier by orders of magnitude through a phenomenon known as electron screening.


How can EFS REACTORS be scaled from a suitcase and larger?

Since our fusion reactions do not continuously sustain fusion chain reactions and our fuel is already ten orders of magnitude denser than traditional deuterium-tritium fuels, we do not need the massive magnetic or electrostatic confinement, typical of multi-story fusion experimental reactors of the past.

We have shrunk the reactor to the size of a suitcase, and we can go smaller and larger for more or less electrical power generation. How we do this is an artifact of the revolutionary approach of the EFS fuel insights and reactor design.


What scientific evidence does EFS have that its approach is superior?

The science behind aneutronic fusion and particularly proton + lithium fusion is well documented in the scientific peer-reviewed literature.

Today, EFS has built a series of laboratory experiments that show fusion reactions on laboratory tabletop. This is confirmed via neutron detection, gamma, and optical spectroscopy that substantiate fusion reactions. There are also historical experiments in capillary fusion that support our insights. Yet, EFS is on the cutting edge, there is not a rich paper trail of peer-reviewed science that is on point. If there were, our approach would be known and the world would be different. However, the science behind all aspects of our apparatus and approach to the practical fusion problem is grounded in known and practiced science. From magnetic and electrical fields to plasma physics, pressure confinement, electromagnetic pulses, and energy extraction via inductive coupling. It is the novel combination of our fuel and traditional electrical engineering and plasma physics that enables the breakthrough.


How cost-effective is the EFS reactor compared to other approaches?

Key reasons for the economic superiority of the Light Element Electric Fusion (LEEF) reactor are the following: a LEEF reactor has no minimum critical mass therefore it can be produced in small or large sizes in a factory. It cannot experience a criticality accident. It has no special nuclear materials of concern for weapons proliferation and no high-level radioactive waste. This set of characteristics will dramatically reduce the design, licensing, construction, safety, public relations, export, and operating costs compared to the fission or fusion reactors they may replace; even compared to the new fission based Small Modular Reactors currently being designed to utilize high asset low enriched uranium (HALEU) fuel.

What the EFS technology enables is a small, modular, and scalable fusion reactor that is safe and inexpensive to manufacture, at the OEM facility rather than on-site. Our patent-pending claims and embodiments create a global transformation in energy production; delivering constant, distributed energy, anywhere, anytime, without generating greenhouse gases or other hazardous waste products.



How does EFS produce electricity?

As the fusion reactions cycle into and out of a chain-reacting state, they create bursts of charged particles that are electromagnetically coupled to the reactor’s oscillating magnetic field. This inductive coupling of plasma pressure becomes electromotive force in the magnetic field which is converted directly to electricity. In essence, a gain transformer using fusion plasma as its core. This allows us to use very efficient power supply regulating techniques to harvest the EMF and subsequently regulate as a switching power supply. Hence, direct conversion into AC or DC output at the voltage, current, and frequency for the desired application, be it 800VDC for a transportation application, or 35 kilovolts AC in an electrical substation.
