The name of Ikea's new SOLVINDEN lamp translates from Swedish as "Sun Wind," as those are the two things that power it. The cordless LED lamp is charged by a combination of the lampshade, which rotates in a breeze, and the sun's rays hitting the solar panel on top. The solar panel also contains a sensor that apparently swiches the lights on when it's dark outside. (There's also an on/off switch.)
What we're not sure of is how the $30 SOLVINDEN is meant to be used, as the stalk on the floor-standing model seems a bit flimsy for permanent outdoor use. With no power cables it's conceivable you could move the lamp from indoors to out each day for a charging session, though that's obviously not practical in cities and certain climes. And though it's tough to tell from the video, the light produced by the lamp appears quite wan.
Still, I'm thankful a global retail giant like Ikea is promoting alternative power, and I think the lamp is an important "1.0" to get mass-market consumers and designers used to the idea. I'm looking forward to both hearing early-adopter feedback and seeing how Ikea incorporates that into future versions.
