CeramicSpeed Bicycle Drivetrain

dezeen reports: [edited]

Danish company CeramicSpeed has developed what could be the world's most efficient bicycle drivetrain.

The Driven drivetrain has no chain or derailleurs, making it more than 99 per cent efficient. The prior drivetrain to beat was a Shimano Dura-Ace at 97.8 per cent efficiency — or 98.37 per cent when upgraded with CeramicSpeed parts.

The Shimano Dura-Ace, like the drivetrains on most bikes, is driven by a chain. While there are many advantages to chains, they eventually stretch and wear.

In contrast, CeramicSpeed's system is connected by a carbon-fibre shaft, which turns 90 degrees from the rear wheel and pedals. On either end of the shaft are 21 low-friction ceramic bearings, which transfer torque from the rider's pedalling through the drive shaft and onto the rear cog.

Icon Construct 3D Printed House In One Day

Wired reports: [edited]

A typical family home in the US takes an average of six and a half months to build. An Austin-based startup called Icon can produce a house nearly 200 times faster. In a day.

To be fair, the company is building houses that max out at 800 square feet. The fabrication is the work of a huge 3-D printer called Vulcan. Engineers run digital blueprints for the home through so-called slicer software, which translates the design into the programming language G-code. That code determines where the printer moves along its track, extruding 3⁄4-inch-thick layers of concrete like icing on a cake. The base material — a finely calibrated mix of cement, sand, plasticisers, and other aggregates — gets poured into a hopper at the top of the printer and flows onto the rising walls below.

The resulting abodes, which will cost $4,000 to build, are the latest addition in the tiny-house movement. In 2019, Icon intends to ship the Vulcan to El Salvador, where it’s slated to print 100 homes for disadvantaged families.

The startup’s next excursion may be even farther afield: Icon is participating in a NASA competition to develop printable space habitats using “indigenous materials,” the planetary soil available onsite.

IBM Computer Debates Humans and Wins


Cnet reports: [edited]

IBM has created a system called Project Debater that competes in what the company calls computational argumentation – knowing a subject, presenting a position and defending it against opposition. At a press event, IBM pitted the system against two humans with a track record of winning debates.

In one debate, Noa Ovadia overall nudged two people among a few dozen in a human audience toward her perspective that governments shouldn't subsidise space exploration. But in the second, Project Debater soundly defeated Dan Zafrir, pulling nine audience members toward its stance that we should increase the use of telemedicine.

Project Debater was trained in advance on debating methods, but not the details of the debate itself, which it found out about only moments before the debate started. To formulate its argument, it had at its disposal a collection of 300 million news articles and scholarly papers, previously indexed for quick search results. But it had to find the information, package it persuasively, listen to its opponents' arguments and formulate a rebuttal.

Although IBM didn't try to pretend Debater is human, it speaks in a well-modulated female voice, and researchers call it "she." At the top of the pillar was a display showing its state of mind with curvaceous shapes in a soothing blue.

Debater showed a grasp of debating's nuts and bolts. It marshalled evidence, told you its stance, explained how its argument would proceed and made its case. It quoted authorities, like German ministers touting the economic benefits of space exploration or scientific studies showing better health outcomes for diabetes patients monitored from afar.

There were gaffes, like the moment Debater said subsidising space exploration "is more important than good roads, improved schools or better health care."
