The design has merit but its engineering needs some more fleshing out. Is it all that green a gadget if the chair charged a battery for use later maybe i dont know if its possible to rock and read. how do you produce it so that its energy benifits out weigh its production..

I'll be brutally honest like most of my design teachers in school: this idea sucks. You put all the effort and energy into manufacturing these parts, create this heavy chair that probably is a PITA to rock, and what do you get? A LED that lights up. Friggin' awesome, something i've always dreamed of having. Too much art, not enough thought.

While the idea is different, the integration of the flywheel and generator could use work. Looks more like the chair was already designed, then had a bunch of industrial parts slapped onto it. If you are going to make it look like a junkyard creation...go all the way!

The idea is good, but I think there's no way that the piston can rotate such a big flywheel just by rocking the chair normally (Angular limit of oscillation is very less in normal rocking of chair).

I question the true sustainability --- It seems like a lot of energy-intensive materials and manufacturing goes into this baby. Now consider shipping weight, place of origin, and post-consumer recyclability. The carbon footprint is huge compared to a standard wood rocking chair and CFL lamp.

I'm sure you'd have to "rock

And what else ?! :/

This is a beautiful object, but seems very uncomfortable as a chair. The lack of padding and armrests would ensure that any reading only occurs in short sessions. So, it defeats its own purpose.

I agree with Michael's comment - if there is no connection to the floor, how can the mechanism actually turn the flywheel? I think the concept is fine, but the design is not at all thought through.

clever design. - you should add - arm rest -

Ridiculous. The dynamo, lever etc would use a lot more energy to process its materials, manufacture, ship, market, etc etc than a little solar collector outside, or even an LED light run on the grid I suspect.

the dynamo is huge compared to the work it does

i love the chair, but more of a gadget than a functional green product to me

It looks very nice but If I see the chair in dentist ordination I would scare much more than usually :).

Pratical and cool. It will be handy for tail-gatting and camping.

I like it a lot. It is really cool and timeless. i would like to see it while working.

It looks very clever and simply. Desing is very nice.

It is the same mechanism like in the old style hemming machine, I think that it has chance to work

a lot of effort for very little impact or reward.

how will fluctuating motion give rise to non-flickering light? Some how the majority of the weight in the fly wheel must be free to rotate on momentum rather than fixed to the "piston rod" that transfers rocker's reciprocating motion to energize the wheel's circular motion.

While the idea of harvesting energy from a rocking chair is a great one, this design does not make much sense as there is no link from the ground to the chair, so there is no way for the generator to make use of the motion to generate power. I think

This is cool. May have to tweak the engineering slightly, but it will work.

beautiful design, questionable functionality
