if only I had mod points today...

Great movie with a great message that seems to really apply here.

Sports - This is where I think they would be useful for me.

I was skiing with my brother; between our spouses on the mountain, and tracking kids in ski school, we were trying to text, call etc. So, given all the gear you have on and the very cold weather, grabbing your phone out of your jacket is a problem. Having something like this, in the $150 - $250 dollar range seems like a reasonable solution to me.

No, I would not just wear them around, just like I would not wear ski goggles instead of sunglasses.

The tiny town of Ashford was engulfed in molten lava. Nearby, residents are wondering if study approval got proper scrutiny.

They commit crimes.
They break laws.
They can kill if left unchecked.

umm... how come you know so much about the rapist mentality?

From the US perspective, I am always surprised at how education is consistently bashed, yet I know many people who have good careers, good income, live in nice cities, and in my view it is THANKS to public education, including the public university system (Univ. of California in my case.).

my movie is animated, so it is only made of electrons - top that IBM!

teach?

"maximizes possible future states of local environment" is what he seems to mean, vs. "maximize entropy" is what is being said. Speaking on behalf of the chemists in the audience, we don't like it when pop lit mangles meanings of words. This is how we wind up with "organic water." /end_rant.

I wanted to add a question - does anyone know how well these work for people with presbyopia?

If so, I would want these for skiing, running, biking & so on. Otherwise, I would just pull out the phone to look at it. BTW, I am not a 24/7 phone junkie at all. But for example when skiing with family & friends, texting and calling is a big pain, but a heads-up display would be perfect.

I just skimmed TFA, but I didn't see any details of the electrochemistry. So this is only a guess, but I think the Al gets turned over to Al2O3, which provides the current to run the motor. If that is true, than you can't just recycle the spent mass, you have to convert it back to a metal, then you can recycle it. Doable, but not cheap.

Also, don't listen to the naysayers: "it's not true cardio...walking is useless...etc" - every little bit helps. Emotionally and physically.

You don't know the watch market. High end mechanical watches can easily fetch more that $10K. If Apple could get a high end digital design into play, and market it to the right people, they could do really well.

What is it with work snacks that make slashdotters want to post AC?
