A stupid question from someone with no technology aptitude. How does one turn the light off, particularly on the silverware example?
Close your eyes?
Swallow the fork?
One presumes the power source is your hand, so the fork will be on if and only if you are holding it. Otherwise, when you put it down, it will disappear into a totally dark miasma unless, of course, someone has turned on the table, possibly by rubbing it's legs.
It's not a stupid question, Betty.
The silverware example is simply a stupid example.
These LEDs will still have to be connected to some kind of power source (battery or AC wiring), and will be turned on/off by some kind of switch. I think the author is just using weird examples to show how this material might also be used as part of things other than something that looks like a lamp or lightbulb. But whatever it is, it'll still have to have some kind of power source and switch.
In addition, wouldn't the cord(s) supplying the power, be a pain in the a** at the table? ;-)

Better still, what happens if one were to swallow one of those dang things?
This is why I continue using vacuum tubes. There is nothing like them.
