Comment Decent, but not a Jesus Watch (Score 4, Interesting) 359

Things I like:
1) Notifications on wrist. #1 use of device. Makes it worth the cost.
2) Super easy to see upcoming events/meetings. I just look at watch face and tap the tap the calendar in the lower right. Brilliant.
3) Paying with your watch for a coffee at McDonald's. Sometimes I'll just go there to buy a coffee just to impress the people behind the counter.
4) Looking at temperature and weather at a glance. See #2.
5) Design is nice.
7) Health tracking feature.

1) Most apps are totally worthless. By the time you find and launch an app that does anything useful on your watch, you could have the real deal on your phone. Only the simplest of apps make sense like the stop watch or the timer.
2) Siri is worthless. It's very unreliable and only good for the simplest of requests.
3) Taking phone calls on the watch is kind of ridiculous. Very hard to hear what someone is saying unless you are in a quiet room and it's a hassle to hold your arm in the air to talk and listen for any length of time. Again, it's just much easier to whip the phone out. Though I will say it has saved me when phone is in the other room and an important call has come in.
4) Battery life is a joke if you use the exercise tracking feature over the course of the day. Then you'll be lucky to get to bed with it still charged.
5) Nothing is more annoying then when you go to look at your watch and it doesn't turn on and you have to tap it with your other hand.

Sorry, I was scrolling up and down the page, got distracted, and copied the answer from the wrong question. Here's what they say:

"How will you replace damaged panels in a highway?

Since our system is modular, repair will be much quicker and easier than our current maintenance system for asphalt roads. We've learned that in the U.S., over $160 billion is lost each year in lost productivity from people sitting in traffic due to road maintenance.

Each of the panels contain their own microprocessor, which communicates wireless with surrounding panels. If one of them should become damaged and stop communicating, then the rest of the panels can report the problem. For instance, "I-95 mile marker 114.3 northbound lane, third panel in, panel number A013C419 not responding".

Each panel assembly weighs 110-pounds. A single operator could load a good panel into his/her truck and respond to the scene. The panel could be swapped out and reprogrammed in a few minutes. The damaged panel would then be returned to a repair center. Think of how this compares to pot hole repair!"

They address this on their website:

"What are you going to do about traction? What's going to happen to the surface of the Solar Roadways when it rains>

Everyone naturally pictures sliding out of control on a smooth piece of wet glass! Actually, one of our many technical specs is that it be textured to the point that it provides at least the traction that current asphalt roads offer - even in the rain. We hesitate to even call it glass, as it is far from a traditional window pane, but glass is what it is, so glass is what we must call it.

We sent samples of textured glass to a university civil engineering lab for traction testing. We started off being able to stop a car going 40 mph on a wet surface in the required distance. We designed a more and more aggressive surface pattern until we got a call form the lab one day: we'd torn the boot off of the British Pendulum Testing apparatus! We backed off a little and ended up with a texture that can stop a vehicle going 80 mph in the required distance."

Not sure how true or relevant this is but they do address it.

Cost doesn't matter if they pay for themselves. "If" being the operative word here. But if it's true, it makes no difference how much more expensive they are than asphalt.

Even if they do cost more than asphalt after factoring in the electricty they produce, how do you place a cost on avoiding all the human misery that will come about from climate change?
