Tasty Tech Eye Candy of the Week (Oct. 2)

The world's largest elevator, the first hydrogen fuel cell airplane and another glass slide round out this week's gallery.

style="text-align: left;">French carmaker Renault showed off it's all-electric concept car, the two-seater Trezor, at this year's Paris Auto Show. One of the coolest things going for it is the clamshell roof, which tips up to allow driver and passenger entry. No doors. Once you sidle in over the top, you sink down into full-wrapping bucket seats and -- thanks to the 350-hp Formula E-based powertrain -- are ready to accelerate from 0 to 60 in less than four seconds.

At the Three Gorges Dam in China's Hubei province, this ship elevator is capable of lifting 6.7 million pounds. Before the elevator opened, it took ships more than three hours to navigate from one side of the dam to the other. Now it takes just 40 minutes. Credit: CCTV via Youtube

Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, are looking to bacterium, paramecium and even jellyfish for inspiration, creating tiny robots with wiggly appendages propelled by an external magnetic field. Thanks to a new algorithm, the researchers have figured out the best magnetic conditions necessary to efficiently drive different kinds of these microrobots. Credit: Phil Loubere

Up top, the windscreen has been formed from a single piece of glass. Below deck are a toilet, refrigerator and table that converts into a bed. The cabin holds eight people and the boat has a top speed of 45 knots. Credit: Aston Martin

style="text-align: left;">Because Wi-Fi and Bluetooth signals are vulernerable to hackers, scientists at the University of Washington wanted to create a way to securely send a password or secret code over radio waves. Their solution: send the signal through a person's body not through the air. Their so-called "on-body" transmission technology pairs the fingerprint sensor on a smartphone with an electronic smartlock. Just touch the doorknob and the fingerprint sensor at the same time and the secure credentials travel through the body to open the door. Credit: Mark Stone/University of Washington

style="text-align: left;">This week in Germany, the world's first four-seater plane powered by a hydrogen fuel cell completed a 10-minute test flight. The plane, the HY4, runs on electricity generated by the fuel cell and has a range of 932 miles with a speed of 102 mph. Credit: DLR

style="text-align: left;">Apparently, glass slides are a thing. This past July, the US Bank Tower in Los Angeles unveiled its glass Skyslide and now the same engineering firm that made it, UK-based Eckersley O'Callaghan, is showing off their Vidre-Slide. Both the ladder and the 29.5-ft slide are each made from a single piece of glass and bonded together with structural silicone. Credit: Frank Kretschmann

Stephen Simiyu, a photographer from Nairobi, Kenya, took home the $2,000 grand prize for his image of a fisherman using a laptop in a canoe on Lake Victoria, Uganda. Credit: Stephen Simiyu / Agility

style="text-align: left;">Toyota's concept car the FCV Plus is being billed not only as an emission-free vehicle, but as a stable source of electric power. Like other hydrogen fuel cell cars, it generates electricity from the hydrogen in its tank. But the "plus" means that it can also process hydrogen from an external source, generating electricity to power household appliances or charge up other batteries. Credit: Toyota
