This is a photo of the Atlantis AK1000, a 130 ton, 74-foot-tall tidal turbine that will be installed underwater off the cost of Scotland. It is designed to supply electrical power for 1,000 households.
Sea water, which is 832 times denser than air, gives a 5 knot ocean current more kinetic energy than a 350 km/h wind; therefore ocean currents have a very high energy density. Hence a smaller device is required to harness tidal current energy than to harness wind energy.

Tidal current energy takes the kinetic energy available in currents and converts it into renewable electricity. As oceans cover over 70% of Earth’s surface, ocean energy (including wave power, tidal current power and ocean thermal energy conversion) represents a vast source of energy, estimated at between 2,000 and 4,000 TWh per year, enough energy to continuously light between 2 and 4 billion 11W low-energy light bulbs.
Both the U.S. and the U.K., for example, have enough ocean power potential to meet around 15% of their total power needs.
Nissan, to show off its autonomous parking tech, outfitted an inn in Hakone, Japan with “self-parking slippers,” autonomous floor cushions that tidy themselves, and a TV remote control that straightens itself on the coffee table. While obviously a marketing gimmick, self-knolling anything is quite appealing to me. ProPILOT Park Ryokan (Nissan)
Boing Boing pal Eric Paulos, an engineering professor and artist at UC Berkeley, has a history of high-tech provocations, from his early work with machine performance group Survival Research Laboratories to his controversial art installations such as a vending machine for pathogens. Above is the performance/prank Eric recently staged to open his Critical Making class: […]
With Vaunt, Intel is taking steps toward solving the Glasshole paradox: how to get consumers to wear wearables that don’t make wearers seem like bad clichés of wearable users.
More often than not, you won’t see an accident coming, which means it pays to be proactive and ensure you have the right tools on-hand before you need them. Whether you find yourself in the middle of a power outage or having car trouble at night, you can make sure you’re still capable of navigating […]
Trains may not be the most popular means of conveyance nowadays, but chances are you grew up playing with toy trains or building a model set to wrap around the Christmas tree. In either case, it’s safe to say that locomotives have long carried a unique sense of awe and scale, especially when they’re hundreds […]
When it comes to redesigning or renovating a living space, envisioning changes before they occur can be tricky for most. Thankfully, the web is home to tools that can remove some of the guesswork, like Live Home 3D Pro for Mac. This app lets you create detailed and furnished floor plans for everything from sheds and […]
