227. HELIUM-3 FUSION
POD regular Al Fin has a new post at the Al Fin Blog with more details on the race for lunar energy.
Navigating the links, there is a fascinating interview in Space Review with Gerald Kulcinski, a professor of nuclear engineering at the University of Wisconsin.
Prof. Kulcinski has a working helium-3 fusion reactor in his lab:
Professor Kulcinski's lab is running the only helium-3 fusion reactor in the world. He has an annual research budget that is barely into six figures and allows him to have five graduate research assistants working on the project. Compared to what has been spent on other fusion projects around the world, the team’s accomplishments are impressive. Helium-3 would not require a tokomak reactor like the multibillion-dollar one being developed for the international ITER project. Instead, his design uses an electrostatic field to contain the plasma instead of an electromagnetic field. His current reactor contains spherical plasma roughly ten centimeters in diameter. It can produce a sustained fusion with 200 million reactions per second producing about a milliwatt of power while consuming about a kilowatt of power to run the reactor. It is nuclear power without highly radioactive nuclear waste.Here's his vision of the future:
Imagine a world thirty years from now. NASA has led the way to returning humans to the Moon and is in the final steps of preparing for human exploration and settlement of Mars. On Earth our environment is cleaner with reliable fusion reactors steadily replacing coal-fired plants and fission reactors. The fuel for these reactors is being mined from the surface of the Moon relegating the mercury, radium and carbon dioxide-laced exhaust from coal-fired plants to "the ash heap of history". The growth of highly radioactive waste from fission power plants is following coal into history. Dependency on highly volatile regions of our planet for energy supplies is steadily diminishing. Clean power is allowing economic development of the world to continue, lifting a higher and higher percentage of the population out of poverty. Is this a possible future for our country and the planet? Professor Kulcinski and his small team of researchers just might have the answer and NASA might provide access to the key enabling resource.
