Solar Driven MHD Power Generator
MHD Large-Scale Utility Power Generation: Solar MHD is the next generation of thermodynamic power cycle with thermal-to-electrical conversion efficiencies higher than 60%. That is, unlike conventional photovoltaic devices with efficiencies on the order of ~20%, our approach is 3 times higher!
This approach is especially well suited to concentrated solar thermal power sources where temperatures in excess of 5,000°C. Unlike conventional power devices, ours is readily scalable and improves in operation with higher input temperatures. In addition, the direct conversion of thermal energy to electrical energy eliminates the inefficiencies associated with thermal-to-mechanical and then mechanical-to-electrical energy conversion as well as other dissipative losses.
Solar radiation presents a boundless opportunity for energy conversion. The energy density on a clear day is approximately 1000 watts per square meter.
In theory, solar concentrators can provide thermal energy at a temperature high enough to provide thermal ionization. Thus, solar-based MHD systems have potential, provided that solar collectors can be developed that operate reliably for extended periods at high temperatures.
Current solar technologies are limited to photovoltaic and solar salt/heliostats (much less efficient and cost effective). Higher temperatures will enable dramatic improvements in overall efficiency and provide selective marketing opportunities in high sun areas
Magnetohydrodynamics Solar Power Technology New Technology Increases Concentrated Solar Conversion Efficiency by 60 Percent.
Our technology uses superconducting magnets to increase the efficiency of conversion from sunlight to electricity by stripping electrons from high-energy plasma jets and thereby generating power with no moving parts.
SUPERIORITY OF SOLAR MHD
The combination of >2000°C plasma and super-cooled magnets provide the mechanism to produce electricity with greater than 60% efficiency. No other non-electro-mechanical means of power generation exceeds 45% in efficiency. Furthermore, with no moving parts, this design has the potential for much greater useful full-time power production life.
Concentrated solar power systems use various focusing optics, e.g., mirrors or lenses, often with tracking systems, to concentrate a large area of sunlight into a small area. Electrical power is then produced with the concentrated is converted to heat used with an electrical power generator.
Use of Concentrated Solar Power to produce the very hot thermal medium is, in itself, a proven renewal energy source. By integrating CSP with the MHD generator as a topping mechanism we gain a synergism that no other power generator to date possesses. Furthermore by using the high-temperature exhaust plasma to drive a closed-Brayton cycle turbine electricity generator thereafter, we gain additional power output that further amplifies the efficiency of the integrated closed loop system.
Because of the higher temperature, generated solar MHD is more efficient than other types of solar thermal technologies that work at a much lower temperature. The laws of thermodynamics tell us that to generate power from a heat source, such as a burning fuel, the higher the temperature, the more efficient it will be, and that is the key advantage of this green technology.
A historic benchmark in the annals of solar energy history. The concept is simple the more heat, the more energy - the higher the temperature, the greater solar thermal potential electrical energy.
Solar radiation presents a boundless opportunity for MHD energy conversion.
CSPU technology takes advantage of concentrated solar thermal power, creating super-hot temperatures that help produce the maximum amount of heat that can be transformed into electrical energy.
We propose a novel approach to utilize concentrated solar power for the extremely high efficiency generation of electrical power. The efficiency of solar cells to converted solar energy into electricity is roughly 33 percent and this efficiency has not been reached yet. By using concentrated solar power to heat a magnetohydrodynamic plasma we will achieve efficiencies in excess of 60%. A better solar mouse trap!

Solar MHD generators have the potential to truly change the world, by vastly improving the state-of-the-art technology for solar electrical conversion. Solar MHD is Free of Pollution.
The efficiency improvement is based on the high temperature of the concentrated solar powered plasma and the extremely high magnetic fields only possible through using high temperature superconductors as permanent magnets. In addition, the requirement of holding the permanent magnetic as close to the magnetohydrodynamic plasma as close as possible is critical to achieving this high efficiency and that will be accomplished through a combination of radioactive shielding and micro channel coolers. In the proposed seedling work, we will demonstrate the ability to achieve this extremely high efficiency with the materials and at the temperatures and cooling required for full system functionality. This will be a great improvement over existing systems to convert concentrated solar power.
Our system design is over twice as efficient at converting solar energy into electricity as is conventional photovoltaic collectors.
It is our contention that solar MHD is theoretically the most efficient way of converting solar energy into electricity.
Solar MHD: A NEW way of converting solar energy into electrical power.
Solar MHD generators are thermal-driven; they avoid certain limitations in the conversion of solar energy into electricity commonly found in current solid state solar voltaic cells.
Our objective is to introduce to the world and bring to market a new and very efficient new way of converting solar energy into electricity. Solar MHD (magnetohydrodynamics) is at the forefront of science. It is a new, advanced technology for generating electrical power using solar energy. Whereas current state-of-the-art solid state solar voltaic cells have a built-in solar electric conversion limits, solar MHD generators are thermal-driven, and not as limited in their conversion of solar energy into electricity as the solid state solar voltaic cells are.
An important advantage of solar MHD, besides the extraordinary conversion efficiency, is the reliability because the channel, its power conversion unit contains no moving parts, and its maximum operating temperature is much higher compared to conventional electrical machines that rely on mechanical shaft power. Therefore, MHD generators are potentially much more efficient than conventional photovoltaic, photo-thermoelectric or steam turbine conversion devices.
This approach is especially well suited to concentrated solar power where temperatures in excess of 3,000°C can be reached. In addition, the direct conversion of thermal energy to electrical energy eliminates the inefficiencies associated with thermal-to-mechanical and then mechanical-to-electrical energy conversion as well as other dissipative losses.
While MHD generators can receive energy from a range of sources, it is perhaps most suited to be used with solar heat energy and Gas/Biodiesel.
Solar Concentrators can provide thermal energy at a temperature high enough to provide thermal ionizations. Thus solar- based MHD systems have potential - International Journal of Scientific and Research Publications, June 2013.
State of the Art of Concentrating Solar Power Technologies:
Concentrating Solar Power uses mirrors to focus the suns energy into high-temperature heat which is used to generate electricity in a generator. Concentrating solar power technologies use reflective materials such as mirrors to concentrate the sun's heat to warm a synthetic liquid to temperatures over 500 degrees Fahrenheit. This fluid heats a liquid that in turns powers steam turbines to produce electricity. Concentrating Solar Power plants use solar radiation as a high-temperature energy source to produce electricity via concentrating heliostats in a thermodynamic cycle. The need for Concentrating Solar Power technology arises because solar radiation reaches the Earths surface with a density that is adequate for heating systems but not for efficient thermodynamic cycle needed for electricity production.
"A solar energy collector focuses solar energy onto a solar oven which is attached to a mixer which in turn is attached to the channel of a MHD generator. Gas enters the oven and an alkali metal enters the mixer. The gas/alkali metal mixture is heated by the collected solar energy and moves through the MHD generator thereby generating electrical power. The mixture is then separated and recycled." NASA - National Aeronautics and Space Administration

It should be noted that a Hughes Space and Communications Company physicist, J. Palmer's solar MHD benchmark experiments done in the 1970's in California, using solar energy to ionize a plasma, proved the concept that solar MHD could work for the first time.
