Paul Allen’s New Plane

Microsoft co-founder Paul Allen unveiled the world’s largest aircraft on Wednesday.

The massive plane rolled out by Allen’s aerospace firm, Stratolaunch Systems, features the longest wingspan of any aircraft ever built, according to Popular Mechanics.

With a wingspan of 385 feet, the six-engine plane will be larger than Howard Hughes’ 1947 H-4 Hercules, known as the ‘Spruce Goose,’ and the Antonov An-225, a Soviet-era cargo plane originally built to transport the Buran space shuttle that is currently the world’s largest aircraft.

The Stratolaunch is an aircraft that is designed to carry rockets between its two fuselages.

In 2011, the project’s cost was initially estimated to be at $300million, though there is no word as to the updated figures.

After the plane reaches altitude, it would then drop the launch vehicle, which will subsequently fire its boosters and launch into space from the air.

A US Air Force Academy cadet demonstrated that school lessons aren’t just about retreading old ground, by turning a classroom exercise into a new ballistic armor made out of goo. In 2014, Cadet 1st Class Hayley Weir’s assignment to combine epoxy, Kevlar and carbon fiber into an anti-ballistic substance inspired her to develop the task into a new type of flexible bullet stopper. read more

First Video Tombstone

The world’s first digital tombstone featuring a 48-inch touchscreen has been unveiled in Slovenia.

Installed in a cemetery in Maribor, Slovenia’s second largest city, the futuristic gravestone can show pictures, video and other digital content.

And the weather-proof device is available for sale now for 3,000 euros ($3,189; £2,588), according to its creators.

Drones for Mars Exploration

The European Space Agency (ESA) has developed a ‘crash-proof’ drone to fly on missions to Mars and beyond.

The new drones could one day help Martian settlers explore lava tubes on the planet by mapping out tight spots that humans cannot reach.

The drone, surrounded by a protective spherical cage and equipped with thermal cameras, deliberately bumps into its surroundings in order to build a 3D-map.

Whether you’re a high-speed thrill seeker or absolute beginner, windsurfing is a solo sport, but an Australian team is working on a fresh new design which changes that. The Wave Chaser is a twin-rig planing hull catamaran, designed to show how catamaran tech could combine with windsurfing to create a new, exciting craft. read more

True holograms – 3D images captured like photographs – are still a long way from replicating the flashy stage tricks that masquerade under the title. Although most holograms are still pretty tiny, a team from Australia’s RMIT and the Beijing Institute of Technology (BIT) have created the world’s thinnest holographic display, encoding a 3D image onto a material just 25 nanometers thick. read more

Stretchable Hologram

For Star Wars fans, Princess Leia’s holographic message to Obi-Wan Kenobi asking for help is a pivotal moment in the 1977 Star Wars film Episode IV: A New Hope.

But it is only now that the technology enabling her desperate plea stands a chance of becoming a reality.

Engineers have created stretchable holograms that can change from one image to another, offering the tantalizing possibility that holographic videos may one day be possible.

CHANGING IMAGES 

The researchers calculated how much a holographic image expands as the material generating it stretches, and how far the image plane moves away from its original position.

Based on these findings, the team created multi-layered holograms made up of two or three different images.

This means that as the surface stretches, one image appears in the place of another.

Using this method, they created a hologram that showed a pentagon in its relaxed state, which transformed into a square, and then a triangle when pulled.

Scientists from the Department of Materials Science and Engineering (SEAS) at the University of Pennsylvania used metasurfaces – flat, ultra-thin surfaces – to make their holograms.

They built on their previous work in creating 3D and multi-color holograms by embedding tiny gold rods in a stretchable film.

This helped them understand how holographic images change with stretching and to see if they could use this information to create a hologram that can switch between images.

AeroVironment’s new Snipe Nano Quadrotor is a man-packable drone with the potential to be carried by every foot soldier, vastly increasing situational awareness and individual capability. The Snipe will also be available commercially later this year for police, first responders and all those who need to be able to see what’s happening in places they cannot safely go.

Announced at AUVSI in Dallas today, the Snipe Nano Quad UAS weighs just 140 grams (5 oz) and fits into a small hard case light enough to be carried – though AeroVironment has not yet disclosed the weight of the entire UAS including the ruggedized touch screen controller. read more

Long popular in other countries, roof-top tents (RTTs) are having their moment in the US. The Santa Cruz-based innovators at Tepui are doing their best to turn that moment into a movement. The company is heavily invested in expanding the RTT market out from hardcore overlanders to the masses of general outdoor lovers and festival campers. read more
