Re: Big Brother
@Ariella - I'm thinking more of a V for Vendetta type world, where the government is all controlling. Anymore it doesn't seem that out of the question...

Re: Many Smart City Applications
I'll have to check out the San Diego city site and see what info I can find. :)

Re: Slightly more seriously, LEDs should make reverbere laws finally inevitable
You bring up some great ideas there John. It will be interesting to see if they come true and how fast they do.

Yeps, you sure can do without the fog lights.

For those not acquainted, a reverbere is the type of streetlight most famous from Paris, where they have had them for a long time. It directs light downward. Besides making pools of light that look really cool in movies, that also means a dark sky; you can see stars from any side street. Which is vastly healthier for people and animals in the city.
American cities have always fought against reverberes because they argue the lights are cheaper without the shields, and anyway reverbere laws lead inevitably to restrictions on advertising, and illuminated skyscrapers, and all the other things that make our cities so glaringly ugly.
Filament and fluorescent light have a basic economy of scale -- the bigger the source, the more efficient, i.e you get a lot more light per unit power out of a 750- or 1000-watt lamp blasting away in all directions than out of, say, 10 75-watt or 100-watt lamps. LEDs scale the other way: little is efficient. A bank of them sitting in reflectors (like an upside down shiny egg box) is really efficient -- and sents all the light downward. Moreover, you can put them all on little gimbal/servo things and point the light where it's needed when it's needed there.
(Person or AI monitoring a surveillance camera doesn't like the look of what's going on in an alley? Streetlights re-aim to brighten it up. Crowd coming out of a show or sports event onto icy pavement or steps? Lights aim at low angles (to stay out of eyes and reveal the sheen of the ice.)
Eventually, with links to self-driving cars, you might normally drive through the city with headlights off; the car won't need them to see and the streetlights will just keep enough light for the car to see in a bubble around each car (or a streak along a busy lane).

Cameras everywhere, already linked to law enforcement. What a happy thought.
I must remember to buy a diary at a second hand store while they're still not recording purchases. And never to write DOWN WITH BIG BROTHER under a streetlight.
Re: Many Smart City Applications
They mentioned 30 intersections. They probably have that information on the city site. It was not relevant for the purposes of this article.

Re: Big Brother
Especially since our governments don't seem especially skilled at keeping user data safe.

Re: Big Brother
I agree. Or just because a technology hasn't been used by law enforcement against someone in the past doesn't mean it won't be used against people in the future.
Even if local governments don't have plans on utilizing data that way, depending on what information they are storing, data retention, etc., the state or federal government may decide to use that data differently.

Re: Big Brother
I agree. It's kind of disconcerting that there hasn't been more coverage about this implementation here.
Plus just because something isn't used for that currently doesn't mean information can't be suppoenaed for use. (And it never seems like the info is used to defend/protect citizens, usually it's used to try to convict them)
