Starship Main Drive Propulsion Systems – Athodyde



Don Davis and Duncan-Enzmann


The Athodyde has an extraordinarily positive effect on mass ratio. It not only gains fuel from the environment, but burns it much more effectively than any proposed engine at speeds of over 90% 99%, and 99.9% of that of light, and higher. This is why:

At these velocities time dilates (slows down) on a starship. (Read To The Stars for a novel based on this equation) The thermonuclear fission/fusion piles slow and the main drives slow down. To an extent this may be overcome by Engine Ganging. It is imaginable using two, four, eight, sixteen, thirty-two, sixty-four, and perhaps even more doublings of energy generation and lance engines; however power plant/engine ganging reaches a limit.

The Athodyde eliminates the need to gang power plants, and to gang engines. The Athodyde’s volume in which hydrogen, deuterium, and other elements are fused is not in the same inertial frame in time at speed of about 99% and above. The volume in which the material gathered by the Athodyde undergoes thermonuclear fusion is in normal space. Energy is produced in normal inertial space and then transformed into momentum in relativistic space. 

The Athodyde is operated with the photon scoop such that the scooped fuel is formed into streams. These may be directed against each other in the manner of clashing particle beams – a method of inducing thermonuclear fusion discovered by Rutherford and his colleagues late in the nineteenth century. 

Shielding the passengers on a starship from the hard gamma flux and neutrons generated by fusion events in the Athodyde should not be a significant problem. The Athodyde would be used before (in front of) the ship – in effect, towing it. It would therefore shelter the ship from interstellar gases and particles by shunting them into its combustion and/or thrust augmentation (afterburning) chambers. In addition at these speeds gamma rays, neutrons, and almost all other particles would be beamed forward of the ship because of beam topple. Beam topple, or head-lighting, operates upon the coulomb electrostatic field, photon propagation, magnetic fields, and the nuclear field. I adumbrate that it must also operate upon the color forces.

Forcing plasma into the Athodyde’s fusion chamber is beautifully solved by scooping. The particles moving inward would be kinetically heated such that they would reach critical frequencies at which both they and associated thermalized photons would be rammed downward into the combustion chamber as the path of least resistance. 

At relativistic speeds, self-pinch acts formidably to constrain plasmas. In a funnel, self-pinch effect may be resonated such that the funnel will feed itself with a self-generated peristaltic traveling wave. Such waves may be generated in plasma vorticies to force fuel down into the reaction volumes to undergo fusion, generating a pulse which operates to gorge the fusion chamber until it generates another pulse. 

At relativistic speeds the gamma rays generated by the fusion pulses could be manipulated to further augment scooping and also feeding of fuel into the reaction chamber.

Athodyde reaction chambers might be operated as pulsed fusion devices, traveling waves of plasma undergoing fusion, and/or a chamber in which thermonuclear fusion is continuous in one location. 

In an Athodyde it would be simple to rotate beams at relativistic speeds. This would cause charge separation and generate an electrostatic Coulomb gradient. A moving charge generates a magnetic field, and at relativistic speeds, magnetic fields undergo self-pinch. In the funnel of an Athodyde the velocity and self-pinch would induce fusion.

At certain thresholds an Athodyde could cross thresholds which would result in genesis of:

White dwarf plasmas
Neutron plasmas
Meson and baryon plasmas
And very probably quark plasmas

On emerging from the stern port of the Athodyde vortex such plasmas could expand successively, they would press against the magnetic fields of the Athodyde and drive the ship forward.

Beyond Apollo, Sixth Seminar

Taurus in Pleiades


Science, Art, Communication, and Cosmology

“We are stardust. We are billion year-old carbon. 
And we have to get ourselves back in the Garden.”
                                (Crosby, Stills, Nash, and Young 1969)

Almost a thousand years ago, Chinese astronomers saw a new star burst forth in the heavens. Half a world away amid the arid beauties of the American Southwest, this same star was watched by Pueblo Indians and marked on sandstone below a crescent moon. It has taken a millennium to decode the message of its passing. For what its light was bringing across 6,000 empty light years to their eyes was the death throes of a mighty denizen of heaven, a funeral pyre so immense that in its seething heart would be created elements for countless minds unborn, as had the elements within those very watchers been conceived amid the dying of still more ancient suns. 

It was a cycle framed of elegance: from dust to star and in the end to dust again. For one brief planetary moment, consciousness would flourish on the hearth of many suns, to disappear too soon into the interstellar night, swept outward with the atoms of its dying star. But in-between – a proton of the universe would gaze out upon itself and ask the question:     

Why? 


Participants in discussions for the Sixth Seminar include:

Isaac Asimov, author, bio-chemist

Donald Davis, artist

Robert Duncan-Enzmann, Fellow, New York Academy of Sciences

Gilette Griffin, Director Princeton Museum of Meso-American Art

Norman Mailer, author

Frederick Pohl, author

Burgertt Roberts, poet

Topics include: 

Cro-Magnon Man and Ice-Age observation of the moon – the beginning of civilization and   the earliest wedding of art and science 

How the process of observation changes the observer

The identity of energy and information and the universe

The process of science: are there limits?

Science and art – complementary objectives


Apollo Seventeen

I hope you have enjoyed this series. What a sight it must have been to sit on the water and watch Apollo launch into the stars. Powerful and magnificent. This is the last seminar of the Voyage Beyond Apollo. It is also the most elegantly described. The questions of discussion were potent then, and they are still so now. Taken together, the seminars pose crucial questions for thinkers of today to reflect upon, and to ponder why? Why are we not colonizing? Why are we not looking for a way to preserve the human race for all time? Why has it taken decades to crawl ahead and then stall out, when in one short decade we raced into the sea of stars? Technology went from radio to rockets in less than 100 years. Rolling forward exponentially in many areas, our technology has unfolded rapidly. Except in space. Why? The inventions of necessary technology for space exploration benefit all areas of human life on earth. Energy, medical, convenience, travel, research, economic growth, jobs.

…… So what happened? Who is out there that is willing to pick the flag up again and run?

One for the money
Two for the show
Three to get ready
Four --- GO!
Just GO.

Beyond Apollo: Fifth Seminar


The overwhelming presence in the night – the stars. They fill the sky, those icy glints of silver, the burnished gleams of gold, the ghostly specter of the Milky Way. These timeless constants across a million revolutions of the Earth around his sun have left their mark and shaped the soul of Man.
What universal symbol adorns the artifacts of cultures spread around the Earth, on art which seeks to draw all men together, and on banners of nations keeping them apart? And where have most men placed their gods if not amid that star-flecked awesome majesty which has come to symbolize the highest aspirations of the human race, the quest for truth and justice, sometimes as out of reach as are the stars themselves?

But pause…..For men are on the threshold of a Dream, the culmination of an odyssey that stretches from the cave. Within this generation they will leave the nursery of the Earth and make that long dark crossing to the stars.

That act, fulfilling, as it will, Neil Armstrong’s prophecy, will be only the beginning. Energies that have been harnessed, from the sun, to launch a starship can also solve on overwhelming crisis for the world – availability , for all, of pollution-less cheap power from the stars. Of lesser things are revolutions made..And what of those who sail from star to star? What will they find? Is life as common in the Universe as stars themselves, or is it rare, more priceless because the distance separating cultures ifs so vast? We do not know.

Perhaps the star lights in the night are beacons marking civilizations resplendent with a thousand Michelangelos, Shakespeares, and da Vincis. A flowering of art to dwarf the best of Earth amid the interstellar suns. OR, again, the lights that light up heaven in that vast celestial city we call the Milky Way may be, without the spark of Mind that seeks to know its origins and communicate with kind across the dark light-years.

Only one thing is certain: if, out of indolence of fear, we do not seek the answer, then our heritage was faulty and the Earth, in no small way, has sapped our essence of humanity which is the Grand Design!
