Megatruck Runs on the Lightest Fuel



The Huge Image options know-how by means of the lens of photographers.

Each month, IEEE Spectrum selects essentially the most beautiful know-how pictures not too long ago captured by photographers around the globe. We select pictures that mirror an essential advance, or a development, or which are simply mesmerizing to have a look at. We function all pictures on our web site, and one additionally seems on our month-to-month print version.

Benefit from the newest pictures, and if in case you have options, depart a remark beneath.

Megatruck Runs on the Lightest Fuel

Huge issues are taking place on this planet of hydrogen-powered automobiles. One of many newest monumental happenings is the debut of
Anglo American’s 510-ton hydrogen-powered mining truck. The behemoth, which can put in work at a South African platinum mine, will exchange a whole 40-truck fleet that companies the mine. Collectively, these vans devour about a million liters of diesel gas annually. The brand new truck, whose energy plant options eight 100-kilowatt hydrogen gas cells and a 1.2-megawatt battery pack, is simply the primary earth-moving step in Anglo American’s NuGen undertaking geared toward changing its international fleet of 400 diesel mining vans with hydrogen-powered variations. In line with the corporate’s estimates, the change would be the equal of taking half one million diesel-fueled passenger vehicles off the highway.

South Pole Snooping Platform

Snooping on penguins for clues relating to how they relate to their polar setting is a job for machines and never males. That’s the conclusion reached by a staff of researchers that’s finding out how local weather change is threatening penguins’ icy Antarctic habitat and puzzling out defend the species which are native to each polar areas. Slightly than subjecting members of the staff to the bitter chilly climate in penguins’ neighborhoods, they’re finding out these ecosystems utilizing hybrid autonomous and remote-controlled
Husky UGV robots. 4-wheeled robots just like the one pictured listed below are outfitted with arrays of sensors comparable to cameras and RFID scanners that learn ID tags in chipped penguins. These permit the analysis staff, representing a number of American and European analysis institutes, to trace particular person penguins, assess how efficiently they’re breeding, and get an image of total penguin inhabitants dynamics–all from their labs and workplaces in additional temperate climates.

Seeing the Entire Scene

This isn’t a hailstorm with items of ice which are straight-edged as a substitute of ball-shaped. The picture is supposed for example an innovation in imaging that may permit cameras to seize beautiful particulars of objects up shut and much afield on the identical time. The metalens is impressed by the compound eyes of a long-extinct invertebrate sea creature that would dwelling in on distant objects and never lose deal with issues that had been up shut. In a single photograph, the lens can produce sharp pictures of objects as shut as 3 centimeters and as far-off as 1.7 kilometers. Beforehand, picture decision suffered as depth of subject elevated, and vice versa. However researchers from a number of labs in China and on the Nationwide Institute of Requirements and Expertise (NIST) in Gaithersburg, Md., have been experimenting with metasurfaces, that are surfaces lined with forests of microscopic pillars (the array of ice-cube-like shapes within the illustration). Tuning the dimensions and form of the pillars and arranging them so they’re separated by distances shorter than the wavelength of sunshine makes the metasurfaces able to capturing pictures with unprecedented depth of subject.

Auto Physique Arms Race

Painters specializing in vehicle detailing may need to start looking for out new traces of labor. Their artwork could quickly be the unique province of a robotic arm that may replicate pictures drawn on paper and in pc applications with unequalled precision.
ABB’s PixelPaint computerized arm makes portray go a lot sooner than is feasible with a human artisan as a result of its 1,000 paint nozzles ship paint to a automobile’s floor a lot the identical manner that an inkjet printer deposits pigment on a sheet of paper. As a result of there’s no overspray, there isn’t a want for the time-consuming masking and tape-removal steps. This degree of precision, which places one hundred pc of the paint on the automobile, additionally eliminates paint waste, so paint jobs are inexpensive. Heretofore, inventive renderings nonetheless wanted the skilled eye and practiced hand of a talented artist. However PixelPaint has proven itself able to laying down designs with a degree of intricacy human eyes and palms can’t execute.
