Developing gravel tire tread patterns is part art, part science – VeloNews.com

Published

Early gravel tires were more a mashup of chunky MTB treads and road tire casings. Now, there are more sophisticated choices, as designers learn what works.

Knobs, grooves, hexagons, ridges: The tread pattern of a gravel tire is covered in protrusions to give it traction, evacuate mud and water, and stand up to harsh terrain. How does a tire manufacturer know how to arrange all those rubber bumps?

The process requires artistry, physics, and a lot of trial and error.

“There is no magic cell phone app that you tell to design this tire for this application,” says Ken Avery, vice president of marketing and product for Vittoria Tires. “You have to talk to a lot of people, gather a lot of data, and look at how a tire is going to interact with a certain type of surface.”

Tires are often designed to perform across several surface types. Thus, they must balance multiple attributes: low rolling resistance with cornering grip, for example. Designers create effective edges to dictate how much grip a tire has, given whether it is propelling you forward or braking your speed.

Ultimately, designing a tire’s tread pattern starts with knowing its application. Johs Huseby, global director of OEM sales at WTB, also oversees product vision. He says 25 or more iterations of a tire may be designed before a final pattern is settled on.

Before a tire reaches a consumer, Vittoria uses pro athletes to test a design. For its Terreno Dry, its cyclocross racers told designers they loved a file-tread tire, but when they braked they’d always skid. The tire’s hexagonal pattern was born: in the rolling direction, the pattern creates hundreds of little ramps, giving it a slick feel. Under braking, the effective edges stand up.

“This doesn’t happen in a vacuum with myself,” says Avery, who has 20 years of tire design experience. “There’s an army of athletes that verify each round of prototypes to make sure we’re on track. Before we release it, they’ve already raced on it many times.”

Early gravel tires were more a mashup of chunky MTB treads and road tire casings. Now, there are more sophisticated choices, as designers learn what works.

Huseby sees a trend toward faster rolling tires for racers, which incorporate a smooth center section with side knobs to improve cornering.

Popular all-conditions tires feature dense tread patterns. “With their low height, you get low rolling resistance, and lots of little fingers that reach out to get traction,” Huseby says.

Some brands go further, producing 35-45-millimeter tires with very little tread. That’s because consumers are starting to realize they don’t need a lot of tread on a gravel bike to still get a decent amount of traction.

“Because you can run such low pressures, you’re achieving grip that way rather than through tread,” Huseby says.

Apple turning to Chinese firm BOE for premium iPhone screens: Nikkei

Apple is in the final stages of certifying premium smartphone displays from Chinese tech firm BOE Technology Group for the iPhone, according to a report from the Nikkei.

The Nikkei, citing sources, said that Apple was “aggressively testing” BOE’s flexible organic light-emitting diode (OLED) displays, adding the company would decide by the end of the year whether to take the company on as a supplier of the panels.

The move is aimed at cutting costs and reducing Apple’s reliance on Samsung, the Nikkei reported.

The U.S. tech giant is expected to unveil its new flagship phones in September, and speculation has grown over what Apple will bring to the table with the latest models. Last year, the company brought out three new models, the XS, XS Max and XR.

Analysts don’t expect the new iPhone, which has been dubbed the iPhone 11 by industry watchers, to include significant updates to previous models. The expectation is that the company will not release phones with any major changes, including 5G, until 2020.

Selecting a Chinese company would be a surprising move, given the company has warned of the impact of the U.S.-China trade war on its business. Many of Apple’s major products, including the iPhone, are produced in China.

The firm has reportedly considered moving some production out of the country, but got a slight reprieve earlier this month after the U.S. announced it would delay tariffs on electronics and other consumer products made in China until mid-December.

Apple was not immediately available for comment when contacted by CNBC.

Renewable energy breakthrough: Scientists economically extract hydrogen from oil | Science | News

Published

on

This method could be used to power hydrogen-powered vehicles, in addition to generating electricity. Hydrogen is regarded as an efficient transport fuel, similar to traditonal fuels such as petrol and diesel, without the associated pollution problems. The process can extract hydrogen from existing oil sands reservoirs, with large supplies found in Canada and Venezuela.

This revolutionary process can be applied to mainstream oil fields, causing them to produce hydrogen instead of oil.

Although hydrogen-powered vehicles are known to be efficient, the high price of extracting hydrogen from oil reserves means the technology has not been economically viable.

However, engineers have now developed an economical method of extracting hydrogen from oil sands.

Dr Ian Gates, of the Department of Chemical Engineering at the University of Calgary, said: “There are vast oil sand reservoirs in several countries, with huge fields in Alberta in Canada, but also in Venezuela and other countries.”

Oil fields, even abandoned ones, still contain significant amounts of oil.

The researchers found that injecting oxygen into the fields raises the temperature and liberates hydrogen, which can then be separated from other gases via specialist filters.

Hydrogen is not pre-existing in the reservoirs, but the addition of oxygen means the reaction to form hydrogen can occur.

Grant Strem, CEO of Proton Technologies which is commercialising the process, said: “This technique can draw up huge quantities of hydrogen while leaving the carbon in the ground.

“When working at production level, we anticipate we will be able to use the existing infrastructure and distribution chains to produce H2 for between 10 and 50 cents per kilo.

“This means it potentially costs a fraction of gasoline for equivalent output”.

This compares with current H2 production costs of around $2/kg (£1.65/kg).

Around five percent of the hydrogen produced then powers the oxygen production plant, so the system more than pays for itself.

Mr Strem stress the economics of the process is favourable.

He said: ”What comes out of the ground is hydrogen gas, so we don’t have the huge above-ground purification costs associated with oil refining: we use the ground as our reaction vessel.

“Just taking Alberta as an example, we have the potential to supply Canada’s entire electricity requirement for 330 years.”

Canada uses approximately 2.5 percent of the world’s electricity – approximately the same amount as Germany.

Mr Strem added: “Our initial aim is to scale up the production from Canadian oil sands, but in fact, we anticipate that most of the interest in this process will come from outside Canada, as the economics and the environmental implications make people look very hard at whether they want to continue conventional oil production.

“The only product of this process is hydrogen, meaning that it the technology is effectively pollution and emission free.

“All the other gases remain in the ground because they cannot go through the hydrogen filter and up to the surface”.

Professor Brian Horsfield, of the GFZ German Research Centre for Geosciences said: “The research is highly innovative and exciting.

“It’s an adaptation of some 1970’s fire-flood production concepts, but tuned to a modern day perspective.

“Declining oil field production infrastructures now stand to get a new lease of life.

“Extensive field testing will be crucial in assessing how the system works on industrial scales and over time”
