Megatruck Runs on the Lightest Gas


The Huge Photograph functions know-how by the lens of photographers.

Each thirty day period, IEEE Spectrum selects the most stunning technological know-how images not too long ago captured by photographers around the environment. We choose pictures that mirror an vital progress, or a craze, or that are just mesmerizing to glance at. We function all visuals on our web site, and one particular also appears on our month to month print version.

Love the most recent images, and if you have strategies, depart a remark below.

Megatruck Operates on the Lightest Fuel

Significant matters are going on in the planet of hydrogen-run vehicles. A person of the newest monumental happenings is the debut of
Anglo American’s 510-ton hydrogen-powered mining truck. The behemoth, which will place in perform at a South African platinum mine, will change an overall 40-truck fleet that solutions the mine. Together, all those vans take in about just one million liters of diesel gasoline each individual yr. The new truck, whose power plant characteristics eight 100-kilowatt hydrogen gas cells and a 1.2-megawatt battery pack, is just the 1st earth-transferring phase in Anglo American’s NuGen task aimed at replacing its world-wide fleet of 400 diesel mining vehicles with hydrogen-run versions. In accordance to the company’s estimates, the swap will be the equivalent of having 50 % a million diesel-fueled passenger automobiles off the street.

South Pole Snooping System

Snooping on penguins for clues pertaining to how they relate to their polar setting is a position for equipment and not adult men. That is the conclusion attained by a crew of researchers that is researching how local climate improve is threatening penguins’ icy Antarctic habitat and puzzling out how to defend the species that are native to the two polar areas. Alternatively than subjecting customers of the team to the bitter cold temperature in penguins’ neighborhoods, they’re learning these ecosystems utilizing hybrid autonomous and remote-managed
Husky UGV robots. 4-wheeled robots like the 1 pictured below are geared up with arrays of sensors this kind of as cameras and RFID scanners that read ID tags in chipped penguins. These allow the exploration crew, representing several American and European research institutes, to observe person penguins, assess how successfully they are breeding, and get a photo of all round penguin populace dynamics–all from their labs and workplaces in extra temperate climates.

Observing the Full Scene

This is not a hailstorm with pieces of ice that are straight-edged in its place of ball-shaped. The impression is intended to illustrate an innovation in imaging that will make it possible for cameras to capture amazing details of objects up close and significantly afield at the same time. The metalens is inspired by the compound eyes of a lengthy-extinct invertebrate sea creature that could home in on distant objects and not eliminate target on items that were up shut. In a single picture, the lens can make sharp pictures of objects as close as 3 centimeters and as far absent as 1.7 kilometers. Beforehand, impression resolution suffered as depth of area amplified, and vice versa. But researchers from numerous labs in China and at the National Institute of Specifications and Know-how (NIST) in Gaithersburg, Md., have been experimenting with metasurfaces, which are surfaces included with forests of microscopic pillars (the array of ice-dice-like styles in the illustration). Tuning the dimensions and condition of the pillars and arranging them so they are separated by distances shorter than the wavelength of gentle makes the metasurfaces able of capturing images with unprecedented depth of subject.


Vehicle Body Arms Race

Painters specializing in automobile detailing may possibly want to get started searching for out new lines of get the job done. Their art may possibly quickly be the special province of a robotic arm that can replicate visuals drawn on paper and in laptop courses with unrivaled precision.
ABB’s PixelPaint computerized arm makes painting go a great deal quicker than is possible with a human artisan mainly because its 1,000 paint nozzles deliver paint to a car’s surface significantly the identical way that an inkjet printer deposits pigment on a sheet of paper. Because there is no overspray, there is no need for the time-consuming masking and tape-elimination methods. This amount of precision, which puts 100 per cent of the paint on the vehicle, also removes paint squander, so paint jobs are a lot less pricey. Heretofore, creative renderings however needed the professional eye and practiced hand of a competent artist. But PixelPaint has demonstrated by itself able of laying down patterns with a level of intricacy human eyes and arms cannot execute.
