I agree with many of your points, and absolutely with the point that we should align economic incentives. I further suggest that instead of allocating tax dollars to such research programs, we just cut those taxes. If economic incentives are properly aligned, then there will be plenty of profit motive for private efforts to research lower carbon cement and whatnot. Unless you think that we can have a second Manhattan Project and dedicate half a percent of GDP to that end and get something usable on the other side ;-)
