Porsche

Porsche's Egger-Lohner C.2 electric vehicle

On June 26, 1898, Ferdinand Porsche's "Egger-Lohner C.2 electric vehicle," better known as the "P-1," rolled onto the streets of Vienna for the first time. In 1899, the P-1 took the gold medal (by a full 18 minutes!) against a field of other electric vehicles in Berlin. Then in 1902, as Porsche put the first all-wheel drive passenger car into production, the P-1 was parked in a warehouse...where it sat untouched for the next 111 years.

Now it's been recovered and is on permanent display, unrestored, at the Porsche Museum in Stuttgart, Germany.

Airbus A350 XWB cold-weather testing

The Airbus A350 XWB flies over Iqaluit, Nunavut in cold-weather testing. Another test version of the aircraft just completed hot-weather, high-elevation testing in Bolivia.

Airbus debuted the energy-efficient A350 XWB at the Paris Air Show in June 2013, pitting it chiefly against Boeing's 787 Dreamliner.

Luca Iaconi-Stewart

A serious paper airplane

Since 2008, Luca Iaconi-Stewart has been working on a scale-model of a Boeing 777-300ER -- made out of manila folders. Though he took two years off during that time to go to college, the now 22-year-old has otherwise spent almost all his waking hours on the project, which is finally nearing completion.

The Laser Girls

3D-printed nails

False nails have been around a long time, but they've been mostly pretty staid. They tend to come in natural colors, red, or pinks, or with Hello Kitty patterns if you're getting really crazy. A pair of designer/artists known as The Laser Girls are turning the fake-nail world on its head with wild 3D-printed creations.
