Video of the Week: Tokamak Fusion Reactor


Posted by in Energy on Friday, February 7, 2014



Solar energy is a potential resource for power. But how about having a mini Sun right here on Earth?

Built at Hydro Quebec's Research Institute facility in Varennes, Que. and operational from 1987 to 1997, the Tokamak Fusion Reactor was an attempt at just that.

This week's video explains the science behind this reactor. Unlike modern nuclear reactors that produce energy through fission — splitting large particles into smaller ones — the Tokamak tried to do the opposite. It used fusion, which has the potential to produce nearly limitless, non-polluting energy. In fact, people may not realize it, but they witness the power of fusion everyday by walking in sunlight.

I worked on this project from 1988-1991. It made some excellent contributions, and had the potential to make many more. Bittersweet to see it in a museum. What is not mentioned in the article, and I believe should have been, is that the tokamak was shut down in its prime as part of a Federal deficit cutting exercise in the 1990's. Those scientists, such as myself, who remain in the field have mostly been working outside Canada ever since. Is this what Canada wants?
