The Internet and tech world exploded in glee when Amazon introduced their drone delivery program, Amazon Prime Air. Though the program is years from reality, it demonstrates what will soon be commonplace. Now, the world’s most famous tech company, Google, is joining the drone game.
A commercial spaceflight company that wants to send people on balloon-powered capsule trips to the edge of space has completed a prototype test of its ambitious endeavor.
On October 24, 2015, World View Enterprises based in Arizona, where the test also took place sent a one-tenthscale replica of the final vehicle to a height of 30,625 meters (100,475 feet) using a high-altitude balloon filled with helium. Now, the company is working towards its goal of sending humans high into the sky by 2017.
This test flight is symbolic of a major step towards a new era of accessible space travel for us all, CEO and co-founder Jane Poynter said in a statement. Of course, this vehicle will not actually be going to space defined as the Karman line, 100 kilometers (62 miles) up. However, what it will do is still pretty impressive.
Check out a video of the test flight above. World View.
World View is buildinglargercapsules for passengers to travel high into the sky, from where they will be afforded views of the curvature of Earth. Each Voyager capsule, weighing 4,500 kilograms (10,000 pounds), will be carried upwards by a football pitch-sized balloon, taking no more than two hours to ascend to its maximum altitude of 30 kilometers (19 miles).
The capsule then detaches from the balloon and a parasail unfolds, known as the ParaWing, which a pilot on board can use to steer the capsule back to the ground anywhere up to 480 kilometers (300 miles) from the original launch site. The total time of the flight is up to six hours.
Sound unbelievable? Well, this latest successful test proved the entire concept, albeit with a 10% scaled version. But the company is confident that the first planned human flights in just two years can be achieved. Full-scale unmanned tests are expected in the coming months.
While each individual system has been analyzed and extensively tested in previous test flights, this significant milestone allowed us to test and prove all critical flight systems at once, said Chief Technology Officer and co-founder Taber MacCallum in the statement. Now were ready for the next major phase of development full scale system testing.
MacCullum told IFLScience that the pilot on the first human flight would likely be former NASA astronaut Mark Kelly, whose twin brother Scott is currently taking part in the Year In Space mission on the ISS. The process to pilot andland the capsule wont be unlike flying the Space Shuttle, said MacCullum. Both are essentially big gliders, with which Mark already has extensive experience.”
A ticket aboard a Voyager capsule will cost you $75,000 (50,000), significantly less than other high-altitude commercial endeavors such as Richard Bransons Virgin Galactic, but still obviously too dear for many. Nonetheless, initially expensive space tourism ventures like this could make space or at least near-space more accessible and hopefully drive the price down in the future.

Freshstep knows the Internet is obsessed with cats, and feels right at home with the feline friendly web. The cat food company even made this fake news report about new bacon scented kitty litter in honor of April Fools. The early joke is featured on YouTubeTrends.
Imagine no crime and no need for police. It may sound alluring, until you realize it’s because there is a fleet of weaponized drones flying in the sky controlled by one corporation. Read more on Collider.
If you’re a cat food company, one of your main objectives is to convince consumers to get a cat. For people on the fence, Friskies made this commercial to push people away from getting a dog. Do you want a slobber machine in your house? I didn’t think so. The video is going viral on sites like Urlesque.
It seems more and more unexpected players are entering the Internet world to promote their products with viral videos.
Heavy machinery company Cat is now trending for this epic, giant game of Jenga they played with heavy machinery. As most people already know, the players must remove a log from the Jenga structure and add it to the top without toppling the rest over.
In this game, the ‘pieces’ are 600 pounds!
Skittles is famous for their strange commercials. But that’s how you go viral right? This one takes the cake. The viral ad is made special for the Internet. The user is asked to put your finger on the skittle in the middle of the screen. The a cat comes and virtually ‘licks’ your finger. That’s all fine and cute, until a fat, middle aged man comes in a cat suit and takes the cat’s place. Too far Skittles, too far.
The aircraft industry is expecting a seven-fold increase in air traffic by 2050, and a four-fold increase in greenhouse gas emissions unless fundamental changes are made. But just how “fundamental” will those changes need to be and what will be their effect on the aircraft we use?
The crucial next step towards ensuring the aircraft industry becomes greener is the full electrification of commercial aircraft. That’s zero CO2 and NOx emissions, with energy sourced from power stations that are themselves sustainably fuelled. The main technological barrier that must be overcome is the energy density of batteries, a measure of how much power can be generated from a battery of a certain weight.
Tesla CEO Elon Musk has said that once batteries are capable of producing 400 Watt-hours per kilogram, with a ratio of power cell to overall mass of between 0.7-0.8, an electrical transcontinental aircraft becomes “compelling”.
Elon Musk on electric aircraft
Given that practical lithium-ion batteries were capable of achieving energy-densities of 113Wh/kg in 1994, 202Wh/kg in 2004, and are now capable of approximately 300Wh/kg, it’s reasonable to assume that they will hit 400Wh/kg in the coming decade.
Another aspect is the exponential fall in the cost of solar panels, which have already become the cheapest form of power in most US states. The expected 70% reduction in cost of lithium-ion batteries by 2025, and the rapid rise seen in the cost of kerosene-based jet fuel means that there will be a large and growing disparity in the costs of running aircraft that will greatly favour electrification. As is often the case, the reasons that will slow transition are not technological, but are rooted in the economic and political inertia against overturning the status-quo.

Biofuels while we wait
Considering the average service-life of passenger and freight aircraft are around 21 and 33 years respectively, even if all new aircraft manufactured from tomorrow were fully electric, the transition away from fossil-fuelled aircraft would take two to three decades.
In the meantime, biofuel offers carbon emissions reductions of between 36-85%, with the variability depending on the type of land used to grow the fuel crops. As switching from one fuel to another is relatively straightforward, this is a low-hanging fruit worth pursuing before completely phasing out combustion engines.
Even though a biofuel-kerosene jet fuel blend was certified in 2009, the aircraft industry is in no hurry to implement change. There are minor technological hurdles and issues around scaling up biofuel production to industrial levels, but the main constraint is price – parity with fossil fuels is still ten years away.
The adoption of any new aircraft technology – from research, to design sketches, to testing and full integration – is typically a decade-long process. Given that the combustion engine will be phased out by mid-century, it would seem to make more economic and environmental sense to innovate in other areas: airframe design, materials research, electric propulsion design and air traffic control.
Bringing aircraft to life
Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and weighs 30 tons, computers in the future may have only 1,000 vacuum tubes and perhaps weigh 1.5 tons. — Popular Mechanics, 1949
Technology evolution of digital storage (2005-2014)
As we can see, we are living in a world of exponential change in technology. We need to step out of our linear day-to-day thinking to fully conceive and make use of what we have to shape the future.
In terms of the cost of computational power, computer technology is advancing more each hour today than it did in its entire first 90 years. With this in mind we can project that the equivalent of a US$1,000 computer today will by 2023 be more powerful than the potential brainpower of a human and, by 2045, will surpass the brainpower equivalent to all human brains combined.
The miniaturisation of digital electronics over the past half-century has followed a similar exponential trend, with the size of transistor gates reducing from approximately 1,000 nanometres in 1970 to 23 nanometres today. With the advent of transistors made of graphene showing great promise, this is expected to fall further to about 7 nanometres by 2025. By comparison, a human red blood cell is approximately 6,200-8,200 nanometres wide.

Putting together this increase in computational power and decrease in circuit size, and adding in the progress made with 3D-printing, at some point in the next decade we will be able to produce integrated computers powerful enough to control an aircraft at the equivalent of the cellular level in near real-time – wireless interlinking of nano-scale digital devices.
Using a biologically-inspired digital “nervous system” with receptors arranged over the aircraft sensing forces, temperatures, and airflow states could drastically improve the energy efficiency of aircraft, when coupled to software and hardware mechanisms to control or even change the shape of the aircraft in response.
Chopping the tail
Once electric aircraft are established, the next step will be to integrate a gimballed propulsion system, one that can provide thrust in any direction. This will remove the need for the elevators, rudders, and tailplane control surfaces that current designs require, but which add significant mass and drag.

The wings we are already designing are near their peak in terms of aerodynamic efficiency, but they still do no justice to what nature has achieved in birds. Aircraft design templates are a century old – constrained by the limitations of the day then, but technology has since moved on. We no longer need to build wings as rigid structures with discrete control surfaces, but can turn to the natural world for inspiration. As Richard Feynman said:
I think nature’s imagination is so much greater than man’s, she’s never going to let us relax.
