Imagine if you could use a vacuum cleaner to suck up all the air pollution in a city—and then turn it into jewelry. That is, in short, the plan for the Smog Free Tower, a new project by glow-in-the-dark smart highway and LED aurora borealis-makers,  Studio Roosegaarde. To help build the air-purifying tower in Rotterdam, the project went live on Kickstarter last week. Backers can purchase a Smog Free Ring and donate 1,000 cubic meters (35,314 cubic feet) of clean air to the city. The new tower is set to begin construction as soon as next month. The structure is, in essence, a 23-foot-tall modular system which uses patented ion technology to filter the surrounding air. “We’re basically building the largest air purifier in the world,” Roosegaarde tells The Creators Project. “The technology is already used indoors in hospitals. It’s safe and tested, we just build the largest one outdoors. Here, people can once again experience what it is to breathe clean air, for free.”

The smog-free park is meant to convince city boards, NGOs and the industry at large of the fact that there are solutions to smog that are both practical and scalable. The plan is to compress the collected smog particles and into high-end jewelry. “Each Smog Free Ring supports the cleaning of 1,000m3 of polluted air,” says Roosegaarde. “For the men, we’re designing Smog Free Cufflinks.” It may be a jewel made of pollution, but it's one that's pure at heart.what is the best grill cleaning brush If the crowdfunding campaign succeeds, construction of the Smog Free Tower will begin as early as September 4, 2015. do air purifiers remove paint fumesPossible future locations include high-pollution cities such as Los Angeles, Beijing, Paris and Mexico City. air purifier hospital

“The Smog Free Park is not intended as a final solution, but as a tangible solution of what a clean future could look like. It’s time to make people become part of the solution instead of the problem.” Head to Kickstarter to learn more about the project.

And They Glow In The Dark Artist Auctions A Jar Of Fresh Air For $860 To Raise Smog Awareness In ChinaTools & Materials Needed Cutting the Box Parts Tools & Materials Needed 24 or 12 volt Computer Fan, 90mm (2) 12 volt power supply Start with cutting out all the MDF parts on the Xcarve using the standard MDF settings. In terms of electronics, I decided to use two 90 mm 24 volt computer fans I’m using a 12 volt DC power supply, so to control the speed of the 24 volt fans you will need a voltage booster. On the voltage booster de-solder the potentiometer and extend the lines while adding two 3k ohm resistors in line with a 10k ohm potentiometer/switch.

Solder the incoming negative power line to the switch and the fans in parallel with the voltage booster. Set the maximum voltage by adjusting the potentiometer on the booster and the range through the 10k ohm switch. Confirm the desired values with a multimeter. If you wanted to avoid the booster and the extra work, then you could just directly hook up the fans to a 12 volt power supply and use a switch. So now it’s simply a matter of assembling all the parts together, and connecting the box. I prefer to put on some yellow glue on the edges of the MDF, as well as some hot glue. The hot glue works as a clamp as the yellow glue sets up and dries. I’m putting in a couple of these small support pieces in the corners to provide a little extra strength. Now as a filter I’m using a charcoal filter meant for a range fan. I’m just fitting it in the box and then I’m notching out the space for the little support pieces in the corners. I’m also doubling up with two pieces of filter and then just continuing to put the box together.

I’m also gluing together some thicker support pieces which I will glue in to the box which the backing will screw in to. OK, so now I have the basic box complete, which means all the sides together, except the back with the fan holes which will screw in later. To finish the box, I’m starting with a coat of shellac, then sanding, then a coat of primer. I’m also adding spackle to any areas that have imperfections. Then painting the pieces white with a flat paint and finishing with a water based polyurethane. This will give you a very nice finish. So the box is finished, now let’s go back to the contents of the box. Trim up the wires and solder everything in place that needs soldering. Then insert the filter into the box. I have these thin pieces of scrap MDF I cut up to keep the filter in place inside the box, and I’m simply hot gluing those to the support pieces to keep everything neat and tight. Next I’m screwing the fans into the back piece, and the holes fit perfectly.

To clean up some of the wires, I’m twisting them around each other so they stay together and then securing to the fan with a plastic zip tie, just because I don’t want the wires to be all over the place. Time to connect everything in place. So I’m connecting the wire I twisted from the fan into the booster and securing it in place. At various stages I confirm that everything works and that nothing has shorted or come loose. Then I bring the parts into the box, and especially the potentiometer twist knob which goes in the side of the box. I put a nut on the outside and then I secure it. The power cord goes in the back, right below the fans, it’s a pretty tight fit. Then I’m hot gluing around it to secure it in place. Also securing the booster with some hot glue, as well as some wires to the side of the box, because I don’t want them to interfere with the fans. And then it’s time to close the back, fit the fans in, and I’m screwing the back in place with some small screws that goes into those support pieces I glued in place.
