City of Edmonton gets its own Ice Castle

When Brent Christensen moved from California to Utah several years ago, he took advantage of the colder climate by building his kids a backyard ice rink … although that rink also included an ice slide, an ice cave, and a 20-ft (6-m) castle-like ice tower. People saw it, they liked it, and the Ice Castles business was born. Since then, Christensen and his team have built their elaborate Ice Castles in a few select American cities every winter. Last month, however, they began construction on a castle in Edmonton, Alberta, Canada – their first-ever creation outside the US. We dropped by, to get a first-hand look at the construction process.Read More

Digital sundial blends 3D-printing tech with ancient ingenuity

You could certainly be forgiven for thinking that the term "digital sundial" is simply an example of an oxymoron, not unlike "jumbo shrimp" or "deafening silence." That hasn't stopped French Thingiverse member Mojoptix from building one, however. It contains no electronics or moving parts, yet it still shows the time from 10:00 to 16:00 in a changing numerical display – with a little help from the sun.Read More

Mojoe puts a battery-powered drip coffeemaker in your travel mug

Is humanity growing tardier and tardier? It sure seems that way when looking at the coffee-on-the-go market.

Detection of "angry" mousing could improve our online experiences

The top 10 things you CAN'T have for Christmas 2015

This is how it's supposed to work: You pen a note to Santa outlining how wonderfully well behaved you've been throughout the year and put forward a wishlist of all the goodies you deserve in recognition of your exemplary performance. The elves then set to work with their hammers and saws and carbon fiber fabrication techniques to produce your heart's desire before Santa loads it up and drops it down your chimney with no regard for physics or reindeer haulage limitations. Ok, it's not going to pan out that way, but that doesn't stop us from setting aside the crushing reality of socks and scented soap for a moment and dreaming a little dream. Here's our annual list of the top 10 things you CAN'T have for Christmas.Read More

Salt-impregnated asphalt de-ices itself

Living someplace that gets snow in the winter may have its perks, but the ice-melting salt that's spread on the roads isn't one of them. Besides the fact that it gets all over our cars and clothing, it also has to be reapplied throughout the winter, harming the environment in the process. If a new type of asphalt reaches production, however, salt-spreading may become a thing of the past.Read More
