Comments Off on These new airless 3D-printed bicycle tires never go flat

Will cyclists pedal bikes with airless tires in the future? BigRep just unveiled a new set of 3D-printed bike tires and took them out for a whirl in Berlin, Germany. The airless tires are made from PRO FLEX Filament – a new thermoplastic elastomer that introduces flexibility to 3D-printing . Designer and test cyclist Marco Mattia Cristofori described the ride as “very smooth”. PRO FLEX Filament can be used with the BigRep One industrial 3D-printer and it boasts “high temperature resistance, low temperature impact resistance” and durability “with excellent damping behavior and dynamic properties.” Related: NASA’s new airless titanium tires are almost indestructible Possible applications for the material include skateboard wheels, sporting shoe shells — and bicycle tires. The flexibility of PRO FLEX is what enables it to work for the airless tires. Maik Dobberack of BigRep told CNET the idea behind the tires is that users could print and customize the treads and internal patterns for varying needs: mountain biking, cycling on roads or handling various weather conditions. Unfortunately, you won’t be able to buy the airless bicycle tires in a store at this point. Dobberack told CNET the tires were an “in-house industrial application design” not intended for large-scale production right now. “The main goal of the design was to inspire and explore the endless possibilities of large-scale 3D-printing,” Dobberack said. We printed the world's first 3D printed airless bicycle tire using our new PRO FLEX material – a TPU-based filament – and took it for a spin in Berlin. Stay tuned for some exciting news! #3dprinter#prototype #bigrep #design #3dprinting#additivemanufacturing #italiandesign #tpufilament A post shared by BigRep 3D Printers (@bigrep3dprinters) on May 3, 2018 at 7:52am PDT The company has also played around with 3D-printed wheel rims , also designed by Cristofori, in “a meeting of advanced design and industry.” Cristofori said, “With 3D printing you can prototype organic forms… It allows you to envision more complex shapes, because you don’t really have any limits.” Last year, Michelin unveiled concept tires that were also 3D-printed and airless; their Vision tire was printed with organic, recyclable materials and was completely biodegradable . + BigRep Via CNET Images and video courtesy of BigRep.com

Two men build a floating "Fatberg" in Amsterdam

Comments Off on Two men build a floating "Fatberg" in Amsterdam

Friends Mike Thompson and Arne Hendriks have created a floating island made of fat, a “ Fatberg ” as they call it. With a current weight of over a metric ton, the car-sized Fatberg began as one drop of fat in a glass of water in 2014. Today, the Amsterdam sight is one to behold, and Thompson and Hendriks hope to someday pull it to the North Pole. Why? The Fatberg is part art-project, part political-statement, part ridiculous-human-experiment. “Basically we’re doing this because fat is a very interesting material—it’s probably the most iconic material of time,” Hendriks told Gizmodo . “It’s organic, but it speaks about energy. It speaks about health. It speaks about over-consumption. It speaks about beauty.” The Fatberg in Amsterdam is not related to the fatberg discovered clogging the sewers beneath the streets of London in 2013. London’s fatberg was a product of improper waste disposal, with fat and grease congealing in the underworld. Amsterdam’s Fatberg is a deliberate creation, composed of various animal and plant-based fats. Its creators hope to someday add human fat, sourced from post-liposuction donations, though this remains an artist’s dream at the moment. Related: Boston man crosses harbor in a pumpkin boat To create the Fatberg, Thompson and Hendriks cut their collected solid fat, boil it into a sludge, then pour it on their creation, which floats at its own dock. Although it is not yet strong enough to carry a human, it does seem to have provided a habitat and food source for seagulls. To this end, Thompson sees the Fatberg as serving a practical purpose. “We’re talking about a floating energy reserve,” Thompson said. “We can maybe replace these melting icebergs with this floating energy reserve that allows us to store energy for times ahead. Because who knows what the future holds.” Via Gizmodo Images via Fatberg

Swytch is revolutionizing the e-bike conversion system

Comments Off on Swytch is revolutionizing the e-bike conversion system

Wheels like the GeoOrbital and Copenhagen Wheel will turn your standard bike into an electric one, but their weight can make it impossible to pedal far in non-electric mode. That’s why we’re so into the new Swytch eBike conversion kit. Swytch puts the electronics and battery on your handlebar, leaving your wheel light and easy to pedal, even when you aren’t in e-bike mode. Electric wheel conversion kits are heavy because they have to carry the battery, motor and electronics all within in the wheel structure. That makes it difficult to pedal when you aren’t using the electric assist. But Swytch claims to eliminate that problem by putting the battery and electronics in a pack that attaches to your handlebars, leaving just the motor on the wheel. That makes it so you can leave the wheel on full-time and still use the bike in non- e-bike mode. The pack can also be mounted in a few seconds (after the initial installation), so you can switch back and forth as needed. More: Swap-in wheel converts any bike into an electric within 60 seconds The pack also includes a light to improve visibility, and riders can control the amount of electric assistance and check range using a control panel on the top of the pack. It also weighs in at a scant 8.6 pounds (10.6 if you choose the larger battery). That’s half of the weight of the electric wheels out there, which typically weigh around 20 pounds. It’s also more versatile, fitting on any size wheel. That means you can now electrify your Penny-farthing, Kickbike or recumbent bike. The small battery has a 25-mile range, while the larger one can take you 50 miles. If you want to snatch up a Swytch, they are running and Indiegogo campaign (which has already surpassed its goal). You can get a kit for $299 right now, over half off the retail price of $650. That’s cheaper than other wheels, which sit in the $1,000 – $1,500 range. + Swytch Indiegogo Via New Atlas

Harrison Ford: The greatest threat is that people in charge don’t believe in science

Comments Off on Harrison Ford: The greatest threat is that people in charge don’t believe in science

Take it from Indiana Jones (or Han Solo, or Rick Deckard) — doubting climate change is dangerous. The actor who played all of these characters, Harrison Ford recently gave a speech at the 30th anniversary gala for Conservation International  (CI). After receiving the Founders’ Award at the ceremony in Culver City, the outspoken advocate for ecological and environmental protection expressed his frustration with Trump — albeit indirectly. The vice-chair of CI said, “We face an unprecedented moment in this country. Today’s greatest threat is not climate change, not pollution , not flood or fire. It’s that we’ve got people in charge of important shit who don’t believe in science .” As IFLScience points out, it is hard to disagree with his assessment. Though 97 percent of climate scientists agree that global warming is a real phenomenon that poses great threats, the Trump administration — led by President Donald Trump — has downplayed the veracity that global warming is real and worrisome. To make matters worse, the administration hasn’t just ignored the science — it has outright attacked scientists and the field’s various branches. Related: Major climate science denial group admits to using false temperature data “I’m here tonight for one reason: I care deeply for the natural world . It’s not about me, it’s not about me at all, it’s about this other world we’re going to leave behind,” Ford continued. “If we don’t stop the destruction of nature, nothing else will matter. Jobs won’t matter, our economies won’t matter, our freedoms and ethics won’t matter, our children’s education and potential won’t matter, peace , prosperity.” “If we end the ability of a healthy natural world to sustain humanity nothing else will matter, simply said. For decades, Ford has advocated for sustainable change. He has met with lawmakers, businesses, and communities to discuss how improvements can be made to conservation policies and practices, according to the Hollywood Reporter . Now, he’s fed up with politicians dragging their feet and is using his platform to speak out and raise awareness. Ford concluded, “Other than my family, doing this work has been the most important thing of my life. Nature doesn’t need people, people need nature.” Via Hollywood Reporter, IFLScience Images via Wikimedia Commons,  Flickr

Harvard researchers just developed self-healing rubber

Comments Off on Harvard researchers just developed self-healing rubber

You’ve heard of self-healing concrete and even the potential of a self-healing starship , but what about rubber that repairs itself? The invention now exists, thanks to researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). In a new study published in Advanced Materials , the research team reveals how they developed a hybrid rubber with both covalent and reversible bonds that is capable of repairing itself. While self-healing materials aren’t new (researchers at SEAS created self-healing hydrogens which rely on water to incorporate reversible bonds that promote self-healing), this is the first time engineers have created a self-healing rubber. The task was difficult, as rubber is made of polymers often connected by permanent, covalent bonds. Because the bonds are strong, they never reconnect once broken. The researchers overcame this by making the bonds connecting the polymers reversible, so the material could break and reform. Related: This rubber-jointed LED table lamp can bend in any direction like Gumby To mix covalent and reversible bonds, the researchers developed a molecular rope (called randomly branched polymers) which tied the two types of bonds together. This rope allowed two previously unmixable bonds (“like oil and water,” according to Li-Heng Cai, a corresponding author) to be mixed homogeneously on a molecular scale. It was this step that produced the self-healing rubber. Unlike typical rubber, the self-healing variety redistributes stress so there is no localized point of trauma that results in cracking. When the stress is released, the material “snaps back” to its original form and the cracks repair themselves. Harvard’s Office of Technology Development has already filed a patent for the technology and is seeking commercialization opportunities. This means that in the very near future, objects that utilize rubber are likely to become more durable. Cai, a postdoctoral fellow at SEAS, Jinrong Wu, a visiting professor from Sichuan University, China , and author David A. Weitz, Mallinckrodt Professor of Physics and Applied Physics, developed the hybrid rubber as a team. Their research was supported by the National Science Foundation, Harvard Materials Research Science and Engineering Center (MRSEC) and the National Institute of Health/National Heart, Lung and Blood Institute. “There is still a lot more to do. For materials science , it is not fully understood why this hybrid rubber exhibits crazes when stretched,” Weitz said. “For engineering, the applications of the hybrid rubber that take advantage of its exceptional combination of optical transparency, toughness , and self-healing ability remain to be explored. Moreover, the concept of using molecular design to mix covalent and reversible bonds to create a homogenous hybrid elastomer is quite general and should enable development of tough, self-healing polymers of practical usage.” + Advanced Materials Via GreenCarCongress Images via Pixabay ,  Peter and Ryan Allen/Harvard SEAS

Worlds largest bike parking garage opens in the Netherlands

Comments Off on Worlds largest bike parking garage opens in the Netherlands

Good news for cyclists in the Netherlands — which, to be honest, is pretty much everyone. The country just unveiled the world’s largest bike parking garage ! By the end of 2018 the 184,000-square-foot facility beneath Utrecht’s central train station will be able to hold 12,500 parked bikes. For years, bicycle enthusiasts have been urging the government to update its parking infrastructure . Martijn van Es, the spokesman for the Dutch cycling organization Fietsersbond, says the country could do much more to accommodate the growing volume of cyclists . He said, “They have been talking about updating the city since 1989. The infrastructure hasn’t changed enough. And there are a lot more cyclists today than there were, [and much of the infrastructure] was built in the 1980s.” Van Es has a point. Bicycles outnumber people in the Netherlands , and the average citizen cycles more than 600 miles a year. Additionally, over one-fourth of the population bikes to work. It’s because of this that parking garages such as the one in development are in high demand. Related: The Netherlands is converting prisons into homes for refugees The Guardian reports that the Utrecht train station is an ideal location for the parking garage, as 40 percent of commuters who arrive there do so by riding a bike. And, according to Tatjana Stenfert, the project manager at Utrecht station’s square, even more bike parking will be added to the area in the future. She said, “We will have 12,500 places by the end of 2018. But then we will have to do some research and find more places for the bikes . It never stops. I look around and everyone is trying hard to find spaces – trying hard and fast.” + CU2030 Via The Guardian , Curbed Images via CU2030

Comments Off on Oregon just approved the nations first tax on bicycles – and cyclists are furious

Riding a bike is good for your health and the environment – so you’d think governments would go out of their way to encourage cyclists, right? Wrong. Oregon — a state known for its avid bicycling culture – just approved the nation’s first statewide bicycle tax . The new excise tax will require consumers to pay $15 for bikes that cost over $200 with a wheel diameter of at least 26 inches. The Washington Times reports that the $5.3 billion transportation package is expected to be signed into law by Democratic Gov. Kate Brown. Both anti-tax Republicans and environmentally conscious consumers are frustrated by the development. It is “an unprecedented step in the wrong direction,” said BikePortland publisher Jonathan Maus. “We are taxing the healthiest, most inexpensive, most environmentally friendly, most efficient and most economically sustainable form of transportation ever devised by the human species.” Related: Sweden wants to fight waste with new tax breaks for repairs According to Oregon Republican Party Chairman Bill Currier, the tax is an effect of Governor Brown’s “endless obsession with finding new and innovative ways to take money out of the pockets of Oregon taxpayers.” There are numerous reasons bikes are better for the environment than automobiles. For instance, bicycles require fewer natural resources to create , emit zero emissions, cut down on health care costs (30 minutes of cycling a day is estimated to save $544/year ) and help combat noise pollution — in addition to other benefits. This acknowledged, why should consumers who strive to get healthier and benefit the environment pay more money to do so? Via Washington Times Images via Depositphotos and Pixabay

Comments Off on China’s largest bike share launches air-purifying bicycles for 20 million citizens

In the near future, 20 million people will be able to clean the air as they cycle. To fight air pollution and create a healthier environment for future generations, eco-innovator Daan Roosegaarde just partnered with Chinese bike-sharing giant ofo and leading Chinese design platform TEZIGN to make his smog-free bicycles available to millions of consumers. Roosegaarde’s highly-anticipated Smog Free Bicycles inhale dirty air, clean it, and then release fresh air into the environment. The bicycles work similarly to Roosegaarde’s Smog Free Tower by providing “a healthy and energy-friendly solution for urbanites, combatting both traffic congestion and pollution issues in the city.” Both the Smog Free Tower and the smog-free bicycles are part of Roosegaarde’s larger vision to fill cities with fresh air. At present, the project is being developed in China and the Netherlands. Roosegaarde , a Dutch artist and innovator, first unveiled the concept for a Smog Free Bicycle at a TED talk. It wasn’t long before excitement grew for the innovation, resulting in the progress made thus far. In a statement, Roosegaarde said, “ Beijing used to be an iconic bicycle city. We want to bring back the bicycle as a cultural icon of China and as the next step towards smog free cities.” Related: Daan Roosegaarde’s smog-sucking tower will clean the skies of China The news was announced at a press conference at the World Economic Forum / AMNC17, in Dalian. Further details about the project will be revealed in coming months. There’s still a long way to go to slash pollution and traffic in China, but the Smog Free Bicycle offers a creative approach to the problem. + Studio Roosegaarde Images via Studio Roosegaarde , Pinterest
