It's hard to say if anything is 'green'. Do cars travel a longer route? Does cost equate to energy, dollars per jewel, in the manufacturing costs of something? So something more expensive uses more energy overall. Lifetime cost of photovoltaic cells is higher than other forms of energy for the lights. That's true even if the photovoltaic cells are free is what Larry Page tells me, and he is well invested in such technology. And if something is cheaper, the savings go elsewhere and still wind up as energy. Is an electric car cleaner than a gas car? It's hard to get a clear answer, and that depends on how 'green' your power source is.
Since technology is what lets us use more energy per person, it could be that technology is the great enemy of 'green'.
This bridge is beautiful in form and function and the way I'd go regardless. To me, this bridge is like using solid state storage instead of hard spinning storage, an type of intellectual 'art'.
@stevewoz: Is an electric car cleaner than a gas car? It's hard to get a clear answer, and that depends on how 'green' your power source is.
A common argument, and one with little validity. Regardless of what kind of centralized power source, producing power and emissions from a single source is always more efficient than producing power and emissions from millions and millions of individual sources. That efficiency results in less pollution.

That bridge was made for walking, but what if it walks all over you? Weird ass design. Reminds me of when I was a kid and used to build stick fences covered in barbedwire to keep my sister out of my room. Ahhh..the memories... Good times. Good times.

Eco? I don't think so. This thing took resources to build and also uses electricity for something that doesn't need it. In the end this thing is just something that itself will eventually end up in the land fill or have to be dismantled and recycled. It's a joke to call it "Eco".
@jmonty: In the sense that it promotes recycling to some who might be too lazy to crush cans with a non-automated tool (or no tool at all for that matter).
I was waffling on whether or not this was a hoax, so I did some Googling. I found this article entitled "Semiconductor Properties of Natural Melanins".
@ripfire: I assume you aren't pranking me. :) As I understand it, semiconductors make good solar cells because it's easy or photons of light to knock electrons loose. That being said, I tested some of my wife's jet-black hair and got nothing. Not conductive. No electrical potential when exposed to UV. Not a definitive experiment, of course.
Interesting to note, conductivity has only been attained in subjects with high concentrations of Eumelanin (Black and Brown), so this would only work with black or very dark brown colored hair. Sorry Matt, you'll have to buy hair by the kilo for this project...
@acuraboytl: My wife's hair is jet black, but does not conduct at all. I tested it. She must be used to me. She didn't even blink when I said, "Honey, I need to cut off a chunk of your hair to check conductivity and semiconductor properties." :)

But how much do you water your plants when it's already raining enough to fill up a watering can? haha #adropofwater

Oh cool. Great to see that they've extended the concept of the walkway overpass (over the freeway) onto a bigger body of water.
But I just realized that this could become new major retail space as well! I mean, just look at the Ponte Vecchio!
Just don't light any cigarettes of lanterns while you're on it. ;)

As for laziness, i have 2 little brothers and a little sister
That's my rechargeable battery/electric motor

Yeah, I've had one of those before, and it's MUCH faster, and requires a lot less patience than this. And it's kinda fun...

How can melanin (a semiconductor) be a good conductor?
