Dragon skin ice sounds like something you’d encounter beyond The Wall in the Game of Thrones fantasy realm. But good news nerds, you can find this magical-sounding stuff right here on Earth—though you’ve gotta be lucky, and willing to travel to some of the most hostile environments on the planet. Like the team of… Read more...

Spaceships can't pull in foreign objects with a almost-magical tractor beam yet, but researchers have been making progress towards that goal. Scientists have now shown that tractor beams are possible, and can actually work . For microscopic objects over microscopic distances at least. More »

Robert sez, "Dungeons & Dragons, now celebrating its 40th anniversary, is about to release its new Monster Manual -- the original Monster Manual was a watershed moment in human history, part of a history that includes a 16th century bestiary, the Augsburg Book of Miracles; bestiaries reveal our profoundly human desire for an enchanted, magical world."

Researchers from the Technical University of Denmark demonstrated a new nanotechnology-based printing technique that produces long-lasting color images on plastic at resolutions up to 127,000 dots per inch, many times more detailed than traditional laser printers. The system uses a laser to alter the structure of nanoscale structures on the plastic material. (A nanometer is one-billionth of a meter; a human hair is around 60,000 nanometers in diameter.) The nanoprinting technique could also lead to new kinds of 3D displays or invisible watermarks. From New Scientist : The surface of the plastic is shaped so that it has lots of tiny pillars, one roughly every 200 nanometers. A thin film of the element germanium is then spread over the plastic. Heat from a laser melts the germanium on each pillar, morphing its shape and thickness. As a result, it reflects a specific color. The coating protects the shapes of the newly carved nanostructures.

 The conveyor belt has long been the center of wacky adventures. From Charlie Chaplin to Lucy, things whizzing by on a flat belt has made for comedy gold. Now you can watch your 3D printed objects whiz past on the Blackbelt, a conveyor system for FDM printing that lets you build huge objects. The Blackbelt Kickstarter will launch in 3 days and you can expect the system to cost about 9, 500 for… Read More

Enlarge / Tesla is starting pre-orders on smooth and textured black glass solar roofs. (credit: Tesla) Tesla CEO Elon Musk announced on Twitter on Wednesday that the company’s solar roof panels would be available for pre-order that afternoon. In a press conference Wednesday afternoon, Tesla and SolarCity executives said the roof would be cheaper, on the whole, than installing a regular tile roof (although not cheaper than an asphalt roof). Pre-orders require a $1,000 payment to secure a place on the list. Tesla also rolled out a calculator on its website using data from Google Sunroof , a 2015 project from the search giant that used 3D modeling to map out every house’s potential for solar panel output. Tesla’s calculator factors in the cost of a 14kWh Powerwall, although purchase of a Powerwall is not required to get a solar roof, as well as any tax incentives that a customer might receive in their state. The "energy value" number featured most prominently is calculated over 30 years, which is the length of the warranty covering power production from the tiles. (Tesla is offering an "infinity warranty" on the tiles themselves.) Tesla Read 8 remaining paragraphs | Comments

Ice Energy A Santa Barbara-based company called Ice Energy has partnered with NRG Energy to deliver 1,800 “ice batteries” to commercial and industrial buildings served by electric utility Southern California Edison (SCE). The units are expected to reduce air conditioning bills by up to 40 percent and eliminate 200,000 tons of CO 2 over the next 20 years. Ice Energy has been building ice-based cooling systems since the early 2000s. Much like pumped storage or compressed air “batteries,” Ice Energy essentially stores electricity by drawing power from the grid at non-peak times to freeze water in a special container. Then at peak times, when the cost of electricity is high and grid operators are struggling to keep up with demand, Ice Energy’s systems kick in and use that block of ice to cool the space that the air conditioning unit normally serves.

Current US law extends copyright for 70 years after the date of the author's death, and corporate "works-for-hire" are copyrighted for 95 years after publication. But prior to the 1976 Copyright Act (which became effective in 1978), the maximum copyright term was 56 years—an initial term of 28 years, renewable for another 28 years. Under those laws, works published in 1958 would enter the public domain on January 1, 2015, where they would be "free as the air to common use." Under current copyright law, we'll have to wait until 2054 . Read more...
