Facebook Test-Flies Drone to Bring Internet to Remote Areas
Posted by Dan Kummer in categories: drones, internet, solar power, sustainability
US social networking giant Facebook announced on Thursday a successful test of its solar-powered Aquila drone, which will beam Internet to people in remote areas.
MOSCOW (Sputnik) — Facebook has been working on Aquila Project with leading experts in aerospace and communication technologies, from NASA’s jet propulsion lab to a small UK firm that created one of the world’s longest flying solar-powered drones.

Huge sail will power JAXA mission to Trojan asteroids and back
Posted by Montie Adkins in categories: robotics/AI, solar power, space travel, sustainability
I wonder, if NASA and/or SpaceX goes to Mars in the 2030’s as planned, by the time the 2050’s roll around a manned attempt to Ceres or Jupiter trojans might be attempted or perhaps an unmanned vehicle made on Mars beats this sail.
Japan’s space agency has its sights on unexplored asteroids as far away as Jupiter, a project that at one level draws on centuries of sail science.

Facebook Heads For The Clouds With Its Internet-Streaming, Solar-Powered Aquila Drone
Posted by Karen Hurst in categories: drones, internet, robotics/AI, solar power, sustainability
Tech now really moving into the clouds.
Although the world is increasingly connected through the internet, there are still four billion people or 60% of the world’s population who do not have such access. 1.6 billion of those people live in remote locations and do not have access to mobile broadband networks. Facebook Connectivity Lab just announced the first full-scale test flight of Aquila, a solar-powered airplane that can be used to bring affordable internet to isolated areas.
Aquila is a high-altitude, long-endurance, unmanned solar-powered airplane. It has a wingspan bigger than a Boeing 737 airplane but weighs hundreds of times less due to its carbon fiber frame. Many of the team members who contributed to the craft had previous experience at at NASA, Boeing, DARPA, Northrop Grumman, and the British Royal Air Force.

Facebook plans to beam fast Internet to remote areas using lasers
Posted by Klaus Baldauf in categories: drones, internet, solar power, sustainability
So far the system can be used to receive signals carrying data at rates of up to 2.1 gigabits per second, though the team claims it could go faster if it were built to absorb infrared, rather than blue, light.
It’s worth pointing out that this isn’t the first piece of hardware to emerge from the Connectivity Lab. Famously, it’s been working on a solar-powered drone to deliver Internet access. That particular project is progressing slowly, though, so despite the fact that the team behind the new laser device plans to test it in a real-world setting, there’s likely still much development ahead before it’s used widely.
The social network is, however, busy pursuing plenty of other projects to take data to the sticks. Most notably, its Telecom Infra Project will use open-source cellular networks to achieve similar results. That way, you see, anyone will be able to sign up on Facebook.

Physicists Say They’ve Figured out How Spacecraft Could Make It Through a Wormhole
Posted by Andreas Matt in categories: climatology, cosmology, physics, space travel, sustainability
A new paper asserts that a physical body might be able to pass through a wormhole in spite of the extreme tidal forces that are at play.
A physical object, such as a person or a spacecraft, could theoretically make it through a wormhole in the centre of a black hole, and maybe even access another universe on the other side, physicists have suggested.

Definitely need this for the farm.
This robot cowboy not only herds cattle, soon it will also monitor the herd’s health and alert ranchers to any injuries or illness to livestock.

Quantum computers show potential to revolutionize chemistry
Posted by Karen Hurst in categories: chemistry, neuroscience, quantum physics, robotics/AI, solar power, supercomputing, sustainability
Like this feature on QC.
If you have trouble wrapping your mind around quantum physics, don’t worry — it’s even hard for supercomputers. The solution, according to researchers from Google, Harvard, Lawrence Berkeley National Laboratories and others? Why, use a quantum computer, of course. The team accurately predicted chemical reaction rates using a supercooled quantum circuit, a result that could lead to improved solar cells, batteries, flexible electronics and much more.
Chemical reactions are inherently quantum themselves — the team actually used a quote from Richard Feynman saying “nature isn’t classical, dammit.” The problem is that “molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision,” according to the Google Research blog. Computing the lowest energy state for propane, a relatively simple molecule, takes around ten days, for instance. That figure is required in order to get the reaction rate.
