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.

In his first U.S. TV interview, Ren Zhengfei describes Huawei as “a tomato” crushed between two superpowers.
The smash hit Chinese government propaganda app Xuexi Qiangguo, which translates to ‘Study to make China strong’, was developed by the technology firm Alibaba, reports Reuters today.
That massive Equifax data breach on September 7, 2017, shocked everyone, but a year and a half later, where the data of all those 143 million Equifax users ended up is still a mystery.
Just a reminder: Print isn’t dead. And now that printers are becoming as portable as cell phones, it might be around for quite some time. Enter the MEMOBIRD Mobile Thermal Printer, a mini-printer that is versatile, portable – and most importantly, never needs a refill on ink or toner. Measuring just a few inches around, […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
