Fusion Research Showing Progress

05/22/2006 11:06 AM

Back in the nineties you couldn't talk about fossil fuel alternatives without bringing up fusion. Then there was a the mistaken claim regarding cold fusion and the whole field got the cold shoulder. With growing energy prices there is a renewed interest in the practically unlimited energy of fusion.

A fusion reactor is filled with a charged plasma contained inside a doughnut-shaped chamber called a tokamak. One problem that has stood in the way of fusion has be a tendency for the plasma to erode the inner walls of the tokamak. Now researchers have found a way to reduce the erosion by using magnetic fields. A small resonant magnetic field creates a "chaotic" magnetic interference on the plasma edge which stoms the fluxes that cause the erosion from forming.

Nuclear Fusion

05/23/2006 7:10 PM

Take a look at the informative General Atomics website of San Diego, California, USA has. It is www.ga.com Select the icon for their fusion program (Icon is a partial view of a containment toris) As a privately held firm, they are advanced in the control of the plasma flux. Their entire sight is very interesting.

Magnetic Fusion Should be Used for Rockets

05/27/2006 2:26 AM

Roger: Progress has been made, but the density of a gas will never match that of a liquid state, hence in essence cold fusion has a much better chance to succeed. It is great they've solve another problem with magnetic confinement but there are still dozens of others needing to be solved. So far 50 years too late and $17 billion spent. As a comparison, the recent Taleyarkhan's bubble fusion results are too real for me to ignore as an educated nuclear engineer. His original paper in Science seemed very credible, particularly with respect to the use of deuterated and non deuterated acetone and the results seen. The recent "denial"by Nature to me is a way to bury this story (and bantering between competing publications ) trying to make it go away, because it may be too easy to make Tritium in my opinion - thinking ahead ten years that is. More research money should be spent on these smaller devices not larger city block sized magnetic solutions. Instead magnetic fusion should refocus their efforts at making rocket engines to burn He3 once He3 production via cold fusion scales up. The recent startling results announced by Yang, et al at ICCF-12 last year in Japan in which hydraulic pressure applied to mineral oil and distilled water produces measureable amounts of gamma radiation is also another piece of startling work. However this story didn't even register on the richter scale so to speak, with mainstream scientific press and again just goes to show how unknowledgeable and asleep they really are on new breakthroughs that are outside the norm in nuclear physics that we've known for the last 70 years. Both of the above stories demonstrate that low energy nuclear reactions(LENR) can be stimulated with devices found in most hardware stores, opening up perhaps a new age of atomic exploration for those who dare to safely investigate. Building city block sized reactors and using huge sledge hammers to fuse nuclei is not the answer. Instead one should let nature and her subtle Quantum mechanical tricks do all the work for you. In the future, folks will laugh at the magnetic fusion method as a white elephant and waste of time and $ that it is. It will be realized that this research would be better applied to rocket engine design to burn He3 and where vulnerable magnetic fields ideas don't matter when one end of the nozzle is used for thrust. -Johnathan Chan [www.atomicmotor.com]
