Groundbreaking Advancements in Energy Conversion

MHD, which is a plasma technology, will replace the 100-year-old steam turbine electric generating technology of Thomas Edison's era. The Plasma in the MHD is created by a process called thermal ionization, where the temperature of the gas is raised to the point so that the electrons are no longer bound to the atoms of gas. These free electrons make the plasma gas electrically conductive.

We will be Retrofitting Existing Gas Power Plants with a MHD Topping Cycle Globally, Increasing the Overall Efficiencies of the Power Plant We have improved and supplemented proven technologies that will significantly increase the output of existing fossil fuel powered power generation plants therefore saving utility companies billions of dollars of investment to build additional plants, and extend the life and capability of existing plants. Once the first is operational, we plan to sell the patented technology to a major power plant design/build firm so they can re-fit prior clients and use the technology for new power plants. The ROI will be dynamic. Investor Relations

MHD Faraday Generator

Closed Cycle MHD System


Magnetohydrodynamic (MHD for short) is the study of the interaction between magnetic fields and moving, conducting fluids. MHD power generation is a method for converting heat directly into electrical energy without the use of a rotating electrical power generator.

The World’s Most Efficient MHD Hybrid Power Plants are the Future of the Power Industry

Power Plants with Magnetohydrodynamic Topping Cycle

MHD devices have already been built as lab prototypes and power plants, establishing proof-of-concept. MHD generators can maximize the energy benefits of both new and existing power plants by increasing their power output capacity and overall system efficiency.

MHD has multiple applications, and has the potential of multiple and very profitable revenue streams.

Retrofitting Existing Power Plants

We have a team of highly trained scientist and engineers. The first product are bringing to market is the MHD Topping Cycle combined cycle plant because this offers a instant huge market with the biggest potential and need. MHD Topping Cycle Combined Cycle Power Plant saves money and energy and improve air pollution, and can potentially increase the efficiency of existing power plants 5% to 15% and pay for themselves with money saved.

"There are ranges of temperature that different thermodynamic conversion cycles work. A topping cycle for MHD works best at the highest possible temperature. The exhaust can then be used for other techniques that work in temperature ranges below MHD high temperature cycle.

Let's say that MHD will improve the overall combined cycle plant efficiency by 5%. Now calculate how the 5% improvement /MW reduces the same 5% reduction in CO2 emission, but calculate the actual savings in pounds of CO2. We then can calculate the number of natural gas plants and the MW's they produce and thus the entire savings in the US if MHD was implemented. It should be a gargantuan number - I am guessing like 10 Trillion lbs of CO2 less. The improvement of efficiency with increased magnetic field is proven – that is a not a subject of argument. The idea of using HTS is novel as it can achieve such a high magnetic field (and thus efficiency). The efficiency has 2 parts – magnetic fields and high temperatures (bread and butter thermodynamics - Carnot efficiency). The application of HTS (High Temperature Superconductors) is novel because we are putting high current MHD at the highest temperatures right next to a low temperature HTS. Enter microchannel cooling! Conventional magnets do not achieve these high fields and thus efficiencies." - Chief Science and Engineering Officer Professor Doug Chrisey

In 1831 Faraday observed small irregular deflections in a galvanometer connected to Thames River water with immersed electrodes at mid span of the Thames Bridge. He interpreted this event that the electrically conducting river water moving through the earth’s magnetic field should produce a transverse emf. The phenomenon of the production of emf by conducting fluid flow through magnetic field was defined as magnetohydrodynamic (MHD) power generation.

MHD Topping Generators can be used in conjunction with steam operated thermal plants utilizing the heat of the gas leaving the MHD ducts. The combined operation of MHD generators along with the conventional thermal plant, will raise the overall efficiency.

"In the MHD generator the advantage of having no moving parts allows to work at higher temperatures than a conventional energy conversion. It is possible to work with temperature around 3000K, and a these temperature the maximum theoretical efficiency would be near 90%." - International Journal of Scientific and Research Publications, June 2013


Magneto-Hydro-Dynamics (MHD) is derived from Magneto-meaning magnetic field, Hydro-meaning liquid, and Dynamics-meaning movement. MHD generates electricity directly from a body of very hot moving gas without any mechanical moving parts. Magnetohydrodynamics works by using magnets to extract electricity from superheated charged gas. In a sense MHD replaces the wires used in conventional electrical generators with ionized gas.

"Today, near all of our power plants (coal, natural gas, hydroelectric, wind, concentrated solar, nuclear, bio-mass) use mechanical turbines to generate electrical power. In the future, if developed, we may use a more efficient generator which operates without moving parts. This is called a MHD generator" - DOE

High-temperature direct-energy conversion capability of an MHD dynamo combined with an already sophisticated steam-powered turbine industry knowledge base allows the cascading cycle design to achieve breakthrough first-law energy efficiencies previously unheard of in the power industry!
