Startups bring new attitude to fusion quest

The lab where a company called General Fusion is trying to spark an energy revolution looks like a cross between a hardware store and a mad scientist’s lair. Bins full of electrical gadgets are piled high against the walls. Capacitors recycled from a bygone experiment are stacked up like bottles in wine racks. Ten-foot-high contraptions bristle with tangled wires and shiny plumbing.

Michael Delage, General Fusion’s vice president for strategy and corporate development, makes sure nothing is turned on when he takes a visitor through the lab, which is tucked away in a bland industrial park near Vancouver. He’s worried about the voltage.

“If you get a broken wire or something like that, you get a very loud bang,” Delage explains.

His company and others are looking for a bang of a different sort: a smashing together of superhot hydrogen atoms that produces a net gain in energy. Nuclear fusion. It’s the same mass-to-energy reaction that’s behind the sun’s radiative power and the blast of a hydrogen bomb, but scaled down to a manageable level for power generation.
