Dr. Robert W. Bussard Has Passed
Tom Ligon who worked for Dr. Bussard has informed me that Dr. Bussard has died. A sad day for all of us in the IEC Fusion community. A great one has passed. We are all diminished by his loss. Fortunately his work will continue. A whole community has developed to support his work: EMC2 Fusion Dr. Bussard was well known to Star Trek fans for inventing the Bussard Ramjet. The Bussard ramjet method of spacecraft propulsion was proposed in 1960 by the physicist Robert W. Bussard and popularized by Carl Sagan in the television series and subsequent book Cosmos as a variant of a fusion rocket capable of fast interstellar spaceflight. It would use a large ram scoop (on the order of kilometers to many thousands of kilometers in diameter) to compress hydrogen from the interstellar medium and fuse it. This mass would then form the exhaust of a rocket to accelerate the ramjet.Dr. Bussard is also known for his recent work on the Polywell Fusion Reactor. The Polywell is a gridless inertial electrostatic confinement fusion concept utilizing multiple magnetic mirrors. It was designed by Robert Bussard under a Navy research contract, and is intended to overcome the losses in the Farnsworth-Hirsch fusor to create fusion power.Dr. Bussard has left a great legacy. In 1960, Bussard conceived of the Bussard ramjet, an interstellar space drive powered by hydrogen fusion using hydrogen collected using a magnetic field from the interstellar gas.Some of his earliest work was in the area of nuclear fission rockets. In 1956, Bussard designed the nuclear thermal rocket known as project Rover.Dr. Bussard initiated some of the first major work on nuclear fusion in the United States. In the early 1970s Dr. Bussard became Assistant Director under Director Robert Hirsch at the Controlled Thermonuclear Reaction Division of what was then known as the Atomic Energy Commission. They founded the mainline fusion program for the United States: the Tokamak. Later, in June 1995, Bussard claimed in a letter to all fusion laboratories as well as to key members of US Congress, that he, along with the other founders of the program, supported the Tokamak not out of conviction that it was the best technical approach but rather as a vehicle for generating political support, thereby allowing them to pursue "all the hopeful new things the mainline labs would not try".If you would like to see Dr. Bussarrd in action and learn a little more about the Polywell design you can find out more at Easy Low Cost No Radiation Fusion. My tears are flowing but the work will continue. God bless you Dr. Bussard and Warp Speed. Update: 09 Oct '007 0244z Rand Simberg has some thoughts. I also want to thank from the bottom of my heart Eric Scheie and Justin of Classical Values who got me interested in Dr. B's work with this post and this one. The Fusor Net folks have some thoughts. Update: 09 Oct '007 2043z You can hear Dr. Bussard and Tom Ligon on The Space Show. I was honored to be able to ask a question. You can listen to the May 8th, 2007 MP3 here. New Energy and Fuel has a couple of posts up: Dr. Robert W. Bussard Passes Away I will be adding links without further comment or update notices.

Who else is working on this project? I don't want such a promising new technology to fall apart because its prime researcher is gone. Cervus · October 9, 2007 02:30 AM Cervus, There are two physicist from Los Alamos National Laboratories working on the project. They have been at it since the project was re-funded by the US Navy in August. These are not second or third tier guys either. They are some of the very best who have taken a leave of absence from their own fusion work to help carry the project forward. One of them is an old friend of Dr. B.'s. In addition they bring the fruits of their previous work to the project. This is a setback, not a catastrophe. M. Simon · October 9, 2007 02:38 AM MS: Thank you for you answer. I am much relieved. Cervus · October 9, 2007 04:45 PM My heart felt condolences go out to Dr. Bussard and his family. God Bless. Matt · October 10, 2007 08:06 PM |

I'm really sorry to hear about this. People like Bob Bussard are few in number, and he will be missed.
Glad to hear his work will continue.
