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.

NASA’s new airless titanium tires are almost indestructible

Comments Off on NASA’s new airless titanium tires are almost indestructible

Flat tires and AAA roadside assistance may soon be past memories. NASA Glenn Research engineers have just unveiled a new super-elastic tire constructed from nickel titanium, a shape memory alloy able to flex, conform, and then return to its original shape even after traversing the most punishing of terrains. While this latest invention is part of a larger, half-century-long effort to build a better tire for extra-planetary exploration, NASA engineers and materials scientists note they’ve already been testing a spinoff version for cars and trucks on Earth. The design of NASA’s new tire takes cues from those used for the 1971 Lunar Rover, which was brought to the moon by Apollo 15. Unlike the common pneumatic tire propping up our electric cars , the Lunar Rover’s wheels used flexible wire mesh. Like rubber tires, the wheels could absorb shocks, but the mesh allowed them to “float” over the soft lunar soil (rather than sink into) and it also prevented over-deflection. Related: NASA confirms asteroid came from another solar system – and it’s incredibly bizarre The Lunar Rover design was considered a major success and engineers used it as a model for future wheels that would later carry heavier loads. The tire is actually the basis for the award-winning Spring Tire , “an airless compliant tire that consists of several hundred coiled steel wires woven into a flexible mesh, giving the tires the ability to support high loads while also conforming to the terrain,” writes NASA. Notably, the headline-making Mars Curiosity Rover , which touched down in 2012, uses aluminum wheels. The choice to use aluminum wheels was based on previous missions which forwent mesh tires without much issue. However, given the size and weight of the Curiosity (roughly that of a 4×4) mixed with the rough terrain, the soft metal alloy wheels began showing loose treads and holes after just a year. Not ideal for a vehicle that cost $2.5 billion USD to build. In anticipation of the Mars 2020 launch, engineers and researchers are revisiting the Spring tire, but juicing it up for the red planet. The new tire improves on traction in soft sand, durability, and a reduced overall weight through the use of nickel titanium. The nickel titanium also gives the tires elasticity, as the metal’s shape memory alloys can rearrange at an atomic level to mold to rocks and bumps and then effortlessly snap its original shape. Indeed, tests conducted on simulated Martian terrain showed that the tires returned to form even when warped to the axle. The original Spring tire made of steel wire mesh stretched and deformed under the same conditions over time. The hope is that the new tires will allow rovers to explore greater regions of Mars or the moon for longer periods, carry heavier payloads, and eventually be used on manned exploration vehicles that would move at much higher speeds. On Earth, the tires would mean far less maintenance, no more flats, and a lot less landfill waste. Rubber tires deemed irreparable are ecologically problematic as they are durable, non-biodegradables that contain high levels of heavy metals and other pollutants. Via Gizmodo Images via NASA

Comments Off on Airless tires could help Toyota make lighter electric cars

Airless tires could boost performance and cut down the weight of electric cars – and Toyota is interested. The automaker recently unveiled the hydrogen-powered Fine-Comfort Ride concept car fitted with the tires at the Tokyo Motor Show . The Fine-Comfort Ride is about as big as a crossover SUV, but chief engineer Takao Sato said the airless wheels could be used on any electric car. The airless tires on the Fine-Comfort Ride are comprised of a band of rubber around a plastic-aluminum hub, reports Bloomberg . Sumitomo Rubber Industries supplied the tires for Toyota . Sumitomo unveiled their Smart Tyre Concept, which includes the airless component, at the Tokyo Motor Show and said in a press release , “Airless tires contribute to greater safety and peace of mind in transportation by freeing the driver from worries about punctures and the trouble of having to manage tire pressure.” Sumitomo said there’s interest from other Japanese carmakers as well. Related: Michelin unveils airless 3D-printed tires that last virtually forever Sato said, “For automakers, the attraction of airless tires is for electrified vehicles.” At the moment the concept tires still weigh about as much as pneumatic tires, but the technology could develop to trim five kilograms – around 11 pounds – from each tire. That’s around 30 percent of each tire’s weight, and the development could come as early as 2025. Sumitomo airless tire project head Wako Iwamura said he aims to have a commercial product by 2020, according to Bloomberg, and that his tires are already comparable in price with those requiring air. The company has already been testing the tires on golf carts and minicars. Sumitomo also pioneered what they called the world’s first 100 percent fossil resource-free tires using all-natural materials back in 2013, and said since then they’ve been working to create “proprietary biomass materials based on raw materials derived from plants .” Via Bloomberg Images via Toyota

Comments Off on Leading Stanford climate scientist builds incredible net zero home, complete with Tesla Powerwall

A leading climate scientist — who has dedicated his career to proving the feasibility of transitioning the world off fossil fuels — walks the walk with his personal home. Professor of civil & environmental engineering and director of the Atmosphere/Energy Program at Stanford University, Mark Z. Jacobson has built an incredible Net Zero home using energy-efficient features that enable the house to generate all of its own energy from renewable sources . Jacobson is one of the founders of The Solutions Project , an initiative backed by scientific research that aims to show how every state in the USA can transition to 100 percent renewable energy . Using the organization’s ethos and his own research as a guide, Jacobson worked with luxury custom homebuilders, BONE Structure to design and build his ultra-efficient home . Related: This new energy concept from Sweden can make any building net zero Located in Stanford, California, the structure is the epitome of future efficient home design that doesn’t sacrifice on style or comfort. The project’s planning began by creating an ultra-low energy thermal shell that would insulate the home and reduce energy requirements. Next, to generate and conserve energy, the home was equipped with solar panels along with a couple of Tesla Powerwall battery packs for storage. This system meets all of the home’s energy needs, including heating, cooling, plug loads and even transportation charging. Jacobson moved into his Net Zero home last summer and has been monitoring its performance ever since. Not only does his energy system generate enough clean energy to meet his family’s needs, but Jacobson has also been able to sell 67 percent of the clean electricity back to the utility grid. + BONE Structure
