Rant, glorious rant! Mostly I roundly curse every politician since 1973 who has not seen it as imperative to diminish the use of fossil fuels, which inspires me to mention the long–planned but never–implemented use of heat from Pickering to replace oil and gas heating fuel in central Toronto. I also mention the abortive attempt of some of the major oil companies to get into nuclear energy (and, by implication, out of fossil fuels) in the 1970s and early ’80s. And in the last minute or so I explain that Elon Musk, no matter what else you can say about him (and there’s plenty to be said), is not enriching himself at the expense of NASA.
