I agree that implementing 10 ideas that tackle 5% of the problem is valuable. Maybe 100 ideas that tackle 0.5% of the problem each. But ideas that tackle 0.00001% of the problem are more useful as a counterexample of what doesn't work. I haven't looked into large scale technical solutions to climate change, but they seem quite unlikely to scale in relation to the consumption of fossil fuels. Sure, coal-burning plants could add carbon capture at the source. But as we decarbonize, we will be left with the use cases like aviation and off-grid mobility where carbon capture at source isn't feasible technically or economically. The only thing that will really work (has the right magnitude of effect) is to stop digging carbon out of the ground and burning it without capturing the carbon at the source, or block the sun's rays so that more energy is reflected to space.
