Quantum dots are nanoparticles made of a semiconductor material, that have unique optical
properties: the wavelength (and thus color) of their
light emission depends on their size rather than the material they are made of.
If party A (greenhouse gas emitters) is harming party B (those harmed by greenhouse gas
emissions), the contention that protecting the
property rights of B will cost A more than it will benefit B should not encourage principled libertarians at the Cato Institute to green -
