Jack, that's not a spec or a standard, just a handle that immediately gives a picture of how long a battery charge lasts in a cell phone app, based on what the app is used for, in this case, talking. I suppose you could say "video watching time" if you had a battery-powered video player. I don't even know if the term is still in use. Back in the day I used to do the same kind of monitoring you describe on my Mac laptop, although it now comes with preset options for Battery vs AC Power, and switches automatically depending on whether it's plugged in.
Ann, I didn't know about the "talk-time" term either. Is there a standard for calculating it? I pay more attention to monitoring the battery hours on my laptop, so I know that there are a whole bunch of things that can affect that (brightness, software being run, communication devices, etc.). I would think that there would need to be a certain standard combination of those types of inputs for comparison across products.
The weakness in any portable system is the battery. If you can recharge in 10 minutes, you have a winner.
And they said nothing good ever came out of California...
Yes, it would be great if they could overcome what you note is a long-time hurdle. This would be a great invention, particularly for the future of electric vehicles and could overcome any remaining hurdles to adoption. It's good to know at least that some very clever people are looking at the problem in new ways.
I didn't know that term, Ann, but it makes sense! Now I will know to use it when I am talking about cell phone batteries anyway and avoid any confusion in the future.
Nice story, Liz. Let's hope this technology reaches its potential. Material scientists have tried many lithium-ion chemistries over the past 20 years and short cycle life has often been a problem. Lithium-sulfur, for example, has offered high energy but has had problems getting past about 50 cycles. Most automakers are looking for a minimum of a thousand cycles. Some are looking for 2,000 because they want some margin for warranties. Let's hope these engineers can do it.
Thanks for posting this: potentially really good news. And yes, it's helpful to use two different terms for total lifespan and length of charge. In cell phone batteries, the latter is called "talk time."
Yes, you're right, TJ...tricky wording there...It depends on what you mean as longer lasting. The battery will run out more quickly but it will continue to be charged and recharged longer, and apparently they are working on the design so it will eventually be longer lasting in both respects. Sorry for the confusion...I should have worded it more clearly.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
