Dubai’s skyline is an ever-growing collection of impressive towering skyscrapers, including the Burj Khalifa, the tallest building in the world. And you know what loves tall buildings even more than tourists do? Lightning.

Instagrammer faz3, also known as Sheikh Hamdan Bin Mohammed Bin Rashid Al Maktoum (the Crown Prince of Dubai), captured this amazing lightning show over Dubai at 1,977 frames per second, turning what is normally a split second occurrence into a beautifully drawn-out ballet of bolts splintering their way across a dark stormy sky.

Two big problems have been vexing environmental scientists for decades: How to store solar energy for later use, and what to do with CO2 that’s been captured and sequestered from coal plants? Scientists from General Electric (GE) could solve both those problems at once by using CO2 as a giant “battery” to hold excess energy. The idea is to use solar power from mirrors to heat salt with a concentrated mirror array like the one at the Ivanpah solar plant in California. Meanwhile, CO2 stored underground from, say, a coal plant is cooled to a solid dry ice state using excess grid power.

When extra electricity is needed at peak times, especially after the sun goes down, the heated salt can be tapped to warm up the solid CO2 to a “supercritical” state between a gas and solid. It’s then funneled into purpose built turbines (from GE, naturally) which can rapidly generate power. The final “sunrotor” design (a prototype is shown below) would be able to generate enough energy to power 100,000 homes, according to GE.

Q-Dots windows to power homes and other buildings.

Researchers at the Los Alamos National Lab may have found a way to take quantum dots and put them in your ordinary windows to turn them into solar collectors.

Photovoltaic cells may be cheaper and more efficient than ever, but you still need to find a place to put them.

Looking to solve these space constraints, Los Alamos partnered with the University of Milano in Italy to see if they could turn windows into electric generators.

As nanocrystals roughly one-billionth of a meter across, — that is as small as 10 atoms wide — quantum dots can absorb light at one wavelength, convert it and re-emit it at another wavelength.

So the dots would absorb sunlight and convert it to a wavelength best suited for the photovoltaic cells, then be guided to the solar cells installed at its edges to electricity.

The University of Milan is responsible for the new industrial method that embeds the dots in a transparent material.

Needs lots and lots of work still.

The humanoid robot Walk-man showed of some of his life-saving capabilities in Genoa Thursday, as the Italian Institute of Technology (IIT) and University of Pisa develop the hardware for disaster response operations.

The 185-centimetre-high (72 inch) robot is a result of the four-year research program which started in October 2013 aimed at assisting or even replacing humans in civil damaged sites including buildings, such as factories, offices and houses.

“This is actually an anthropomorphic robot that was developed to assist humans during situations where actually we have physical disaster: disasters made by humans or the environments that becomes hostile and dangerous for emergency responders to intervene,” said IIT Senior researcher Nikolaus Tspgarakis.

Australia’s coast, being both great surf territory as well as a primo shark habitat, is getting a technological upgrade to keep the swimmer-fish twain from meeting: A shark-spotting drone nicknamed the “Little Ripper.”

A joint venture between Aussie philanthropist Ken Weldon and Aussie bank Westpac, the $250,000 battery-powered unmanned helicopter will be deployed in the skies above New South Wales. On Sunday, New South Wales Premier Mike Baird heralded the drone as the future of oceanic search and rescue.

The Little Ripper will be able to monitor the shore for an hour before its battery kaputs, according to the Sydney Morning Herald. It’s part of a push for non-lethal, greener shark attack deterrents in Australia, where encounters are reportedly rising. They’re still fairly rare — as of November, there were 14 shark attacks off the Australian coast in 2015, reports The Guardian — but that’s a spike from the typical average of five or so. A separate $16 million shark detection initiative in New South Wales also includes buoys with advanced sonar that can, according to its creators, detect sharks 90 percent of the time.

The person in the article is not very smart. 1st you never offer a tempting challenge to a hacker in public forum. I have known too many and followed to many since the 80’s. 2nd, house burgulars are not even close to the calibur of hackers.

I own a 2013 Nissan LEAF SV with telematics functions known as CARWINGS. CARWINGS connected to my car via an app also called NissanConnect EV that was hacked by Troy Hunt and came into to the news this week. Nissan issued two different statements about the hack and eventually shut off the app completely.

LEAF owners are concerned that because the app was easy to-hack with the LEAF’s VIN number that access could be used for malicious use.

The LEAF’s VIN number can be clearly seen through the windshield.

If the human race is to survive in the long-run, we will probably have to colonise other planets. Whether we make the Earth uninhabitable ourselves or it simply reaches the natural end of its ability to support life, one day we will have to look for a new home.

Hollywood films such as The Martian and Interstellar give us a glimpse of what may be in store for us. Mars is certainly the most habitable destination in our solar system, but there are thousands of exoplanets orbiting other stars that could be a replacement for our Earth. So what technology will we need to make this possible?

We effectively already have one space colony, the International Space Station (ISS). But it is only 350km away from Earth and relies on a continuous resupply of resources for its crew of six. Much of the technology developed for the ISS, such as radiation shielding, water and air recycling, solar power collection, is certainly transferable to future space settlements. However, a permanent space colony on the surface of another planet or moon adds a new set of challenges.

Scientists see cislunar outpost as critical to advancing future Mars missions.

NASA researchers based in Colorado are devising efforts to build a human outpost in cislunar space — the region around the moon. Unfortunately for fans of space tourism, these outposts are not designed to be the Airbnb of tomorrow. Rather, the habitats are to be used as in-between points to facilitate travel to near-Earth asteroids or Mars.

Scientists and engineers at NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) Projects are researching life-support needs, updating astronaut radiation protection, and rethinking communication systems, to enhance the habitability of orbital communities parked in cislunar space.

Google Fiber is heading close to home for its next location: San Francisco. Google announced this morning that it intends to bring its fast gigabit internet to “a portion of San Francisco,” specifically to apartments, condos, and affordable housing units. Details on exactly where and when are nonexistent for now, and Google suggests that we may be waiting a while to hear more.

What Google Fiber does say is that it won’t be building out its own network in San Francisco, as it’s done in many other cities. Instead, it’ll rely on existing fiber networks to provide its service. That may limit what Google can do and where it can go, but it also means a much faster path to launch. “To date, we’ve focused mostly on building fiber-optic networks from scratch,” Michael Slinger, Google Fiber’s business operations director, writes in a blog post. “Now, as Google Fiber grows, we’re looking for more ways to serve cities of different shapes and sizes.” Google Fiber is already taking this approach in a couple other markets, including Huntsville, Alabama, where earlier this week it announced plans to launch using the city’s municipal network.

As it’s done elsewhere, Google Fiber plans to provide free gigabit internet service to “some public and affordable housing properties” in San Francisco. It’s also working with a nonprofit to teach people basic internet skills, like setting up an email account and applying for jobs.
