Don't forget that we're overdue for another miracle development in batteries, as well as the next iteration of sprayed-glass coating that turns everything waterproof and bacteria-free.

And solar cells, and some vaccine for dental cavities.

And the moon doing some "once in a millennium" thing.

Like spontaneously disintegrating?

(Seveneves is a good book, I highly recommend it.)

This is one of my biggest pet peeves. Every week on the news you hear about a miracle graphite battery that is super thin and has 500 times the capacity. The first time I was excited, the second disappointed, and every other time I just sighed. I'll believe it once it's hit the market. I don't understand why the news reports experimental research just because it's novel. Of course the researchers will play along because it makes their work seem important, stroking their egos and helping them get future funding.

All I can think now is "Will a new battery size of rolodex be able charge your iPhone 400 times and power your electric car drive from Folkestone to Stoke-on-Trent?"

And "New solar panel technology powers 30 middle Atlantic households or 400 French sheds."

Ad impressions.

any time I see the word 'study' I immediately skip to the next link. I don't believe anything from a 'study' anymore.

I have seen this before too, and I ask myself what impact it has on the life of the lamps.

Others have made me think about other issues with this, like how the lamps will get their connection? -Someone then mentioned through the power grid network. And then I think you are limited to the bandwidth of that. How much infrastructure needs to change to make this li-fi happen?

edit: spelling error, also I am thinking only about the impact on for example an office installing this. At a home this is too expensive for what it gives.
