Researchers at the University of Stuttgart are preparing to test a solar heating system capable of long term storage as part of “Solspaces,” a three-year project that kicked off in March 2012.
During winter, the zeolite acts as a sorbent, adsorbing humidity from the moist air flowing through the reservoir. The binding of the water vapor with the sorbent produces heat energy, which is used to heat the building.
In the summer months, the process is reversed with solar cells heating the air flowing through the reservoir to 180° C (356° F). This desorbs the water molecules, allowing the sorbent to dry out and be ready to store heat once again. The team says this process has the potential to almost entirely eliminate heat loss as it doesn’t require water in the tank to be maintained at a high temperature year-round.

Teaching children the basics of computer science isn’t as simple as teaching them to tie their shoes. How often do you see a parent sitting down with their kids, walking them through a line of code or pointing out the components of a motherboard? Probably never. Because kids think it’s boring. And parents think it’s hard. Today, children grow up surrounded by shiny objects that look and act like magic. There are screens that respond to touch and computers that can do just about anything a five-year-old can dream up. But even though kids have been immersed in technology since birth, it’s rare for them to actually know how it works.
Tory peer Baroness Rawlings wants us to use electric blankets to keep warm this winter.
"Everybody needs an electric blanket," [..] "I thought I didn’t like them until I moved to the country and my friends who lived here took me to one side and said in no uncertain terms that I would need one. It’s like a chain whisper."
Once installed, I couldn’t believe I had ever lived without one – getting into bed at night is like climbing into a lovely warm embrace, without all the hassle of another actual human being. "They are especially good for single people," agrees Anna.
Reading this got me thinking… why not give it a try and buy one?

Create a learning environment for the course that is open and continuous.
That is to say that anyone can join the course space at any time or leave at any time, the content is open to registered and unregistered alike. Learning material is surrounded by interactions and there are general interaction spaces through discussion areas. The idea is to build up an open community of learning.

Amidst all the effusion of how MOOCs are signing up hundreds of thousands of learners, democratizing education, and forever changing the way future generations will learn, we often overlook learners’ low engagement and high attrition rates. While technology that teaches so many people at scale is certainly impressive, if an online course doesn’t inspire users to think critically about the subject matter, it has not met its course objectives.
It’s not enough to slap together a series of textual notes, PowerPoint slides, or talking-head videos followed by a quiz, and call it “eLearning.” In order to compensate for the lack of real-time learning feedback, you must use the advantages of the Internet to overcome its disadvantages and engage learners.
OK, Amazon won the Cyber Monday news jackpot. Bezos and his merry band announced plans to one day deliver packages with drones, nabbing legions of headlines in the process. Before we get all serious, let’s take a moment to appreciate how awesome it would be to have a UAV touch down in your front yard and drop off your new coffee maker.
The concept isn’t new. Several companies including FedEx and even a vaporware taco delivery business have thrown out the idea of using an unmanned aircraft to deliver products to customers. But Amazon is a bit bigger than a couple of guys talking about delivering munchies to those with a must-have-now craving, and they have produced a nice video showing how their service, called “Prime Air” might work. When Amazon talks, even if it talks a bit crazy, people pay attention
Heard it on the radio while driving back home from work. Thought it was a great idea; too bad it shouldn’t happen any time soon.

The Spruce Stove isn\’t stoked with split cordwood or puny sawdust pellets, but rather entire tree trunks are fed into its fiery maw. Photo: Spruce Stove
Americans purchased nearly a quarter-million wood stoves last year, and despite their popularity in the modern era the aesthetic options would be surprisingly familiar to colonial-era shoppers. Fortunately for fans of clean lines, Dutch designers Michiel Martens and Roel de Bohr have remade the wood-fired heating stove for the contemporary home. Called the Spruce Stove, their bespoke 55-gallon fireplace breaks with tradition by trading out a boring hinged door for a portal that irises open like an airlock on a sci-fi space ship, or the opening credits of a Bond flick.
