Tom Ligon, an engineer who worked with Dr. Robert Bussard, is giving a talk on fusion powered rockets at the International Space Development Conference in Dallas. Here is a link to Tom’s Power Point Presentation at ISDC. Scroll down the page and click on the button in the lower right.
In other news Tri Alpha Energy has just raised $40 million in venture capital for nuclear fusion.

Tri Alpha Energy, which hopes to commercialize nuclear fusion technology, has raised $40 million from Venrock Associates and others, according to VentureWire.
The company, which grew out of the University of California at Irvine, says its advanced plasma fusion technologies could be used to generate electricity as well as eliminate waste from nuclear power plants. A plant based on its technology would cost less than a conventional nuclear plant. Tri Alpha was founded in 1998 and has raised funds in the past.
Tri Alpha is working on a generator in which hydrogen chases boron, according to literature from UC Irvine. These atoms then form a helium atom, which is placed in a particle accelerator. Slowing down the helium generates electricity.

I have some links to their proposed design at Easy Low Cost No Radiation Fusion. Scroll down and look for the Hendrik J. Monkhorst information.
Here are some more details on the venture capital deal from UC Irvine.

Norman Rostoker, research professor of physics and astronomy, received $5.2 million from Tri Alpha Energy Inc. to research a plasma electric generator that will use as fuel a mixture of hydrogen and boron. In this generator, hydrogen will chase boron in a cylinder, eventually resulting in helium nuclei that will be made to escape into a particle accelerator. The backwards-running accelerator will slow down the nuclei, turning the energy released into electricity.

Here is the patent for the Monkhorst/Rostoker design.
