Voting third party is not a wasted vote, even if the third party won't win. It's playing for the long term. In a first past the post system, the two parties are kept in balance by political alliances and gradual evolution of the platforms. (Yes, a major party can die, but it doesn't happen often.) If one of the major parties sees that a third party is attracting a lot of votes, they might be inclined to shift their party platform in that direction, to recapture some of those votes in the future.

Comment Re:Fresnel Lens or ZOne plate? (Score 2) 132

Zone plate would limit you to one color and cost a lot of intensity. According to the journal article, it is a Multilevel Diffractive Lens (MDL), and the authors distinguish it from a Fresnel lens, claiming it is 100x thinner and corrected for the entire bandwidth, unlike a Fresnel lens. The MDLs use subwavelength scattering elements, but I don't fully understand how it works.

Sure, energy costs money. But pollution (associated with energy production) doesn't cost money (to the user). So, energy doesn't cost as much as it should cost with externalities included, and people are more inclined to use incandescent bulbs than they would be.

Actually, pretty much every good has externalities associated with it, so having no regulation at all is a good way to turn the Earth into a trash heap. You can argue about how much regulation is worthwhile though.
