I love reading about clever ideas like this, but at the same time, I'm leery of the notion that we can fix the climate at the last minute, a narrative that stems from the late capitalist imperative to innovate. We don't need to innovate to find a solution; we need to act.
We’re not going to act. I’ve come around to accepting that. We need to plan on what we do if we don’t reduce carbon emissions because it’s too late for that already. Even if everyone is driving electric cars that’s just going to lower the price of gas and people will put it to other uses.
a) There is a floor to oil prices. No one will produce it for less than the cost of production, no matter how low demand falls.
b) It's possible to raise the price arbitrarily using a carbon tax, which becomes much more politically expedient once prices are already lower and fewer voters are relying on oil for their commute.
