Governments like to talk about the importance of diversifying the economy, but when it comes to providing stimulus, the same old sectors usually top the priority list.

The resource, auto and aeronautics industries are where governments typically put most support.

But in British Columbia, an alliance that represents some of the smartest technology companies the province has ever produced is hoping to change all that.

As the race to replace fossil fuels heats up, a few Canadian startups are betting on the nuclear option. "We need a game-changing energy innovation," Simon Irish, chief executive of Oakville, Ont.,-based Terrestrial Energy, said in a recent interview. Renewable power like wind and solar aren't able to meet the world's growing energy demands, Irish says, so people have to rethink nuclear energy. "This is clean energy on a massive scale," he said.

Depuis soixante ans, les physiciens essaient de maitriser la fusion nucléaire. L’objectif ? Produire de l’énergie propre et quasi inépuisable. Vont-ils bientôt toucher au but ?

Startups bring a new attitude to the energy quest — will it be enough? 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.

De l'énergie verte... et illimitée! Voici le rêve fou de scientifiques qui veulent lutter contre le réchauffement du climat grâce à une technologie révolutionnaire : la fusion nucléaire. Au cœur de cette aventure, un Québécois qui ne souhaite rien de moins que sauver la planète.

On a sprawling campus in southern France, a revolutionary kind of power plant is steadily rising from the ground. Scientists and engineers from dozens of countries are building a facility that will eliminate all the negatives of today’s power supplies -- greenhouse gas emissions, toxic air pollution, radioactive meltdowns -- while still providing massive amounts of electricity around the clock. At least, that’s the goal.

Sharing Science Radio is one of the ventures by the members of UBC Sharing Science, a group of students dedicated to making science interesting and accessible to all members of the community. Sharing Science toured General Fusion and spoke with Michael Delage, General Fusion's VP Strategy and Corporate Development, on the differences between nuclear fusion and nuclear fission, why General Fusion has built a huge metal everlasting gobstopper (or at least what looks like one), and how to tame plasma with a temperature of 150 million degrees C.

After decades of slow progress and massive investment, some fusion power researchers are changing tactics You can accuse fusion power advocates of being overly optimistic but never of thinking small. Fusion occurs when two elements combine, or “fuse,” together to form a new, third element, converting matter to energy. It is the process that powers the sun, and the fusion world's marquee projects are accordingly grand.
