IS hacks UK solar firm site in revenge
Posted by Karen Hurst in categories: cybercrime/malcode, solar power
I always caution folks to never say “never” especially around hacking and worst case scenarios relating to security. Granted there is a balance around not going too overboard. However, when it comes to being risk adverse and determining how much risk your company can absorb must be a core piece of your assessment. And, an attack like the one by ISIS in this article can not be allowed.
LONDON: ISIS terrorists hacked the website of a UK-based solar firm as revenge for the killing of one of their British Muslim members, a media report said on Sunday.

Artificial control of exciplexes opens possibilities for new electronics
Posted by Karen Hurst in categories: computing, electronics, materials, solar power, sustainability
Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers at Kyushu University were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.
This new way to control electrical properties by slightly changing the device thickness instead of the materials could lead to new kinds of organic electronic devices with switching behavior or light emission that reacts to external factors.
Organic electronic devices such as OLEDs and organic solar cells use thin films of organic molecules for the electrically active materials, making flexible and low-cost devices possible.

Here’s how we could build a colony on an alien world
Posted by Julius Garcia in categories: alien life, habitats, solar power, space travel, sustainability
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?

This smartphone’s display is also a solar charger
Posted by Shailesh Prasad in categories: mobile phones, solar power, sustainability
You phone does all kinds of things when it’s just lying there: checking your Facebook feed, pulling down Google Now updates, receiving emails and text messages. One thing it’s not doing: giving your battery a break.
Kyocera is working to change that. How? By sandwiching a solar panel to a smartphone display. It’s something they’ve been working on in conjunction with Sunpartner Technologies. They actually showed off their progress last year at Mobile World Congress, and they returned this year to give the crowd a glimpse at their updated prototype.
It’s an Android device with a five-inch screen, and like some of Kyocera’s other phones it’s waterproof and quite rugged. Curious how the solar layer affects the phone’s display? Reports from people that have spent time with the device say that you’d be hard pressed to notice the difference. That’s because the .55mm panel that Kyocera has integrated into their latest prototype’s display is 85% transmissive.

Quantum dot solids: This generation’s silicon wafer?
Posted by Karen Hurst in categories: electronics, engineering, quantum physics, solar power, sustainability
Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids – crystals made out of crystals – can help usher in a new era in electronics.
The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.

Graphene May Soon be Produced Commercially, Thanks to a Chance Discovery
Posted by Shailesh Prasad in categories: electronics, materials, solar power, sustainability
Graphene is too delicate to be produced commercially, but it seem that scientists have now stumbled upon the correct method of tuning it.
Graphene has many extraordinary properties. It is carbon, but it comes in the form of a two-dimensional, atomic thick, honeycomb lattice.

Mark Zuckerberg Offers These Predictions for the Future of the Internet
Posted by Shailesh Prasad in categories: drones, internet, military, solar power, sustainability, transportation
On Monday at the Mobile World Congress in Barcelona, Mark Zuckerberg partook in what he thought would be a “fireside chat” with Wired’s Jessi Hempel but which was verifiably not fireside, and was, actually, a keynote.
Inverse picked out the best nine moments of this interview.
1.) Zuck doesn’t know that Aquila will meet regulations but is just confident that it’ll work out

SolarCity will use Tesla’s Powerpack to deliver solar power even when it’s dark
Posted by Shailesh Prasad in categories: Elon Musk, solar power, sustainability, transportation
No source of energy is perfect and one of the traditional drawbacks of solar energy has been that it’s tough to generate new power when it’s dark outside. However, SolarCity announced this week that it’s taken a big step toward fixing this problem by agreeing to use Tesla’s 52 MWh Powerpack lithium-ion battery storage system for its massive solar power project that it’s building in Hawaii for the Kaua’i Island Utility Cooperative (KIUC). SolarCity, of course, is chaired by Tesla CEO Elon Musk so the decision to go with the Powerpack is pretty convenient for both companies.
MUST READ: The FBI has laid a clever trap for Apple
SolarCity says it believes that its collaboration with Tesla will produce “the first utility-scale system in the U.S. to provide dispatchable solar energy, meaning that the utility can count on electricity being available when it’s needed, even hours after the sun goes down.” To be clear, using the Powerpack won’t completely eliminate the need for non-solar resources at night since it’s projected to feed up to 13 megawatts of electricity onto the grid, which will only reduce the amount of power used by non-renewable sources.
