Forsiden - Green Carbon DIY Cheap 100 Hour Candles I am always on the look-out for homemade counterparts to store bought preparations. These DIY ’100 hour candles’ definitely fit the bill. In less than 5 minutes you have an inexpensive, refillable ’100 hour candle’ that will light up your home in the darkest of times. And for you ladies – these homemade alternatives are far more aesthetically pleasing than the store bought versions. Supplies The supplies you need are pretty straight forward. Just as a side note, it took me forever to find the liquid paraffin. Step One: Create Opening For Wick I used some grass-trimming shears but you can use a knife or any other sharp tool to create your opening. Step Two: Insert Wick Instead of just putting the wick in like a candle, we’re going to place it so that it is doubled over. After having both ends through, pull down so that only a tiny amount of the folded piece of wick remains. Step Three: Pour Paraffin Into Jar Fill up your 1/2 pint mason jar with the liquid paraffin. Step Four: Secure the Top
Artificial graphene could outperform the real thing A new breed of ultra thin super-material has the potential to cause a technological revolution. “Artificial graphene” should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting. For the first time, scientists are able to produce and have analysed artificial graphene from traditional semiconductor materials. Such is the scientific importance of this breakthrough these findings were published recently in one of the world’s leading physics journals, Physical Review X. A researcher from the University of Luxembourg played an important role in this highly innovative work. Graphene (derived from graphite) is a one atom thick honeycomb lattice of carbon atoms. The University of Luxembourg is heavily involved in cross-border, multidisciplinary research projects. University of Luxembourg researcher Dr.
How to Make a Candle Heater With the cold season coming to a close I wanted to share one more survival craft that you can do in order to provide some off-grid heat to a small insulated area with just a candle! I got this idea straight from the HeatStick.com site, where instead of ordering one of their “Kandle Heeters” I decided to make my own and share with you guys how you can too (it cost me about 15 bucks to make compared to 30 dollars (plus shipping) if you were to buy one). How it Works The basic purpose of this heater is to capture the heat given off of a candle flame and to concentrate it into a steel and ceramic radiator assembly. Putting it all Together The process for putting together the candle heater is very simple: What You Need one 4″ ceramic (not glazed) potone 2″ ceramic (not glazed) potone 1 1/2″ ceramic (not glazed) pottwo 1 1/2″ x 1/4″ washersthree 1 1/4″ x 1/4″ washersthree 1″ x 1/4″ washerseight 3/4″ x 1/4″ washersseven 1/4″ nutsone 3″ x 1/4″ bolt Assembly Instructions Making the Stand Test Results
Fun, interesting science? 10 amazing online sources In today’s TED Talk, Tyler DeWitt makes a fantastic case for a simple idea: make science fun. Educators and writers get caught up in the idea that science needs to be taken seriously, and forget that the best way to get kids interested is to… make it interesting. Too much emphasis on being accurate can lead to lessons that are incomprehensible, or just flat-out boring. Tyler DeWitt: Hey science teachers -- make it fun“If a young learner thinks that all viruses have DNA, that’s not going to ruin their chances of success in science. Now to the good news. Minute Physics. Vi Hart. It’s OK to be Smart. Comics! I F***ing love science. There are lots of wonderful places to find science news. Of course, there is our very own TED-Ed. There’s also The Story Collider, the story-telling event dedicated to how science makes a difference in lives and changes people.
How To Make A Survival Stove (Car Heater) With winter coming soon for many of us who live in the colder climates, getting stranded in your car can become a dangerous possibility. As a result, everyone’s emergency car kit should contain the ability to heat your car if you were stranded or holed up waiting the passage of a winter storm. Even if running your engine is an option, you may need to conserve fuel for the return trip. Also, carbon monoxide can build up inside a standing vehicle while the engine is running, even if the exhaust pipe is clear. What You’ll Need A small empty metal can: You want this to be slightly taller but thinner than a standard roll of toilet paper. How to Put it All Together Prepare the toilet paper: The first step is to take out the central cardboard tube from the toilet paper roll, leaving only the paper behind. Place the smaller can into the larger one and position it in your car: The larger can provides an insulating barrier and some protection for passengers and your car. Controlling the Burn Rate
‘NSA-Proof’ Email Service ‘ProtonMail’ by Harvard and MIT Students becomes massive success | Hack Read Necessity is the mother of invention, the old adage has proved its worth again when a group of Harvard and MIT students came together to create an NSA-proof email service. ProtonMail, the new email platform launched at European Organization for Nuclear Research (CERN) by five security experts ‘who were drawn together by a shared vision of a more secure and private Internet,’ is probably safer and secure than Lavabit, Snowden’s defunct email service. The service has many benefits over conventional email service providers. As the founders explain: They are incorporated in Switzerland, which is well known for offering the strongest privacy protection to both individuals as well as countries. The site uses end-to-end encryption and intense user authentication measures, implying that the data transmitted through their services is inaccessible to the ProtonMail team itself, let alone other people. It is free forever and does not allow tracking or logging of personally identifiable information.

New class of nanoparticle brings cheaper, lighter solar cells outdoors Think those flat, glassy solar panels on your neighbour’s roof are the pinnacle of solar technology? Think again. Researchers in the University of Toronto’s Edward S. Rogers Sr. Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that outshines the current state of the art employing this new class of technology. This new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots, could lead to cheaper and more flexible solar cells, as well as better gas sensors, infrared lasers, infrared light emitting diodes and more. Collecting sunlight using these tiny colloidal quantum dots depends on two types of semiconductors: n-type, which are rich in electrons; and p-type, which are poor in electrons. “This is a material innovation, that’s the first part, and with this new material we can build new device structures,” said Ning.
