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.

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.

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 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.

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?

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.
