Kick the fossil fuel habit

Tom Rand, an entrepreneur, venture capitalist, innovator, philosopher and MaRS Discovery District advisor, just launched his book, Kick The Fossil Fuel Habit: 10 Clean Technologies to Save Our World. It talks about things like solar power, wind power, hydro power, biofuels, smart buildings, and more that are leading the way to a sustainable future. Tom believes technology already exists to kick the fossil fuel habit. Not only is a world powered by clean technologies possible – it’s absolutely necessary!

Who is Tom Rand?

Both in the YouTube clip for the book and in his TED talk, Tom speaks about possible replacement to fossil fuels we are hooked on. His confidence that we can kick the habit is contagious. Just a few solar farms in Sahara can produce enough electricity for the entire world! Instead of burning coal, use geoexchange technology that can reduce energy use and carbon emissions by up to 70%, and lowers peak electrical load in the summer months. Tom is currently implementing this technology by converting a derelict building at 357 College St., Toronto, into a green hotel.

Sounds great. However I am a pessimist, or an extremely cautious person (call it what you like), and I have been taught by experience that, if something sounds too good to be true, it probably is. As some of you may know, it is actually possible to make a gravity-powered clock, for example. The only catch is that manufacturing this clock will be a lot more expensive than a regular alarm clock and a lifetime supply of batteries.

I will be happy if someone explains to me that I am mistaken and the obstacles to Tom’s suggestions that I see are no obstacles at all.

Tom suggests, instead of burning coal, to drill about 10 km or 6 miles down to extract heat and use heat exchange to produce electricity.

Isn’t 6 miles a little too much to drill routinely? Won’t the heat dissipate before getting to the surface? What happens to the heat balance if you have too many holes in the earth crust, and how many is too many? How does the cost of drilling and geothermal well maintenance compare to the cost of the energy we hope to obtain?

Another suggestion of Tom’s is putting up a solar farm in Sahara. Great, but do we already have a technology to transfer all this almost-free electricity to the places where it is actually needed? And if we do, why indeed are we still using coal?

By the way, if you have an invention, would like to commercialize it but do not know where to start, you should contact Kevin Downing at MaRS or fill in the MaRS Discovery Document online. And the advisors from MaRS will pick it up from there!
