Our next speaker for TEDx is golden

The next speaker we’ve confirmed is Rob McEwen. On the face of it, Rob is a ‘business’ speaker. After all, he's Chair and CEO of US Gold and Lexam Explorations. He famously ran Goldcorp , one of the most stunning successes in Canadian business. During his time at the helm, Gold Corp's market capitalization went from $50M to $10B. He was named by Canadian Business magazine as Canada's Most Innovative CEO in 2006 and made Fast Company magazine's The Fast 50 Champion of Innovation list. In June 2007, he was named to the Order of Canada.

Like the very best of business people, he's used his money for good. His largest contribution has been in establishing the McEwen Centre for Regenerative Medicine at the Toronto General Hospital, helping maintain Toronto’s global leadership in stem cell research.

So, Rob certainly has the credentials to count as a business speaker. But I see him in a different light. To me, he represents the best i n creative and innovative thinking, and the courage to try something entirely new. The way he made Gold Corp successful was by defying the 'known' truths of how you run a mining company. He exploited the power of the Internet and collaborative cross-industry creativity to reach for success. When I find my students languishing in the doldrums of thinking the same old way about problems, I evoke McEwen's experience to jolt them into letting go of what they 'know' and striking out with contrarian thinking.

When you set up a program like this one for TEDxIBYork, you have to reach beyond your own limited experience, so you ask lots of people for their opinion about who would be a great, not a good, speaker. Rob was described as charismatic by many of the people I polled. I've wanted to hear Rob speak for a long time; I can't wait to see him on our TEDxIBYork stage.

Innovate to Zero - an energy imperative

The necessity for carbon-free energy
Bill Gates' incisive talk on energy was one of my favourites this year. His acute analysis went step by step through his thinking with startling clarity. (In fact, if you want a template for a perfectly formed presentation, you could do worse than use this model.)

The Gates Foundation is working on vaccines and seeds. But climate is more important to the very poor than anything else. And the price of energy is critical to them too. In order to arrest climate change,we need to do more than just reduce carbon - we have to Innovate to Zero, from the current 26B tons of carbon/year (of which the US is responsible for 20B tons).

Carbon math is inescapable

Carbon = Population x Services/person x Energy/service x Carbon/unit of energy

Gates dryly pointed out the simple mathematical fact - if you want carbon to go to zero, then one of the terms of this equation has to go to zero. We can take the terms one at a time. Population is going to rise to 9B before leveling off. Services per person are rising as huge numbers reach for the middle class. Efficiency can drive down Energy per service, but realistically, not to zero. That leaves Carbon/unit of energy as the only factor that can be driven to zero. That requires a miracle. And we need to achieve that miracle by 2050.

Next, Gates identified five candidates for that miracle:

• carbon capture and storage
  
• nuclear
  
• wind
  
• solar photovoltaic
  
• solar thermal.
  

Each approach has unsolved problems and concerns, and would take major breakthroughs to deliver the miracle. We need thousands of people working on all these challenges and he exhorted that work to begin.

The potential of nuclear
Gates pointed to nuclear as a strong contender in this race. The current technology in nuclear power plants dates back to the 1950s and uses rare enriched uranium. Furthermore, the process is quite inefficient and produces a lot of waste, without a sound plan for its disposal.

Gates disclosed that he is backing an initiative out of Intellectual Ventures, run by his friend and former CTO of Microsoft, Nathan Myrvold. Terrapower's uses U25 (i.e. spent uranium that is now considered nuclear waster) as fuel, rather than U28. It has the potential to use all that nuclear waste we now worry about so much. Even better, the process takes place in a sealed reactor in the ground, which you fill once every 60 years, eliminating the risks of accidents associated with refuelling. This approach has the potential to meet the deadline, through 20 years in development and 20 years for wide deployment. (Gosh, as much as I admired Gates' analysis, I wouldn't go so far as to put him in charge of a deadline!!)

The Gates talk is one of the first to go up on TED.com here. It's well worth watching.

Other TED talks on nuclear
Nuclear wove its way through a couple of other TED talks. Stewart Brand, an early environmentalist and creator of the Whole Earth Catalog has come to the conclusion that nuclear is the only answer. The risks of nuclear are less than the risks of climate change. And TerraPower's approach reduces those risks further. He outlines his reasoning in his new book Whole Earth Discipline: An Ecopragmatist Manifesto. He participated in a debate about nuclear power against Mark Jacobson, a Stanford civil and environmental engineer, whose most persuasive argument against nuclear power was that it couldn't come online fast enough to make a difference, mostly because of regulatory delays. That's the 20 years Gates allows for deployment after development has proven the concept.

And of course one couldn't help but link the Countdown to Zero movie (described in an earlier post) with Innovation to Zero. Using nuclear power creates a market for the uranium in all those weapons that should be dismantled).
