Watch: Kite power system performs first flight in North Sea

Makani conducted the first flights of its energy kite from a floating platform in the North Sea. The energy kites use a wing tethered to a ground station to efficiently harness energy from the wind, generating electricity at utility-scale. The kite flies autonomously in loops, and rotors on the wing spin as the wind moves through them, thus generating electricity that is sent down the tether to the grid.

Watch: An underwater internet of things

To investigate the unexplored oceans covering most our planet, researchers aim to build an underwater network of interconnected sensors that send data to the surface; — an underwater “internet of things.”  MIT researchers could use a battery-free underwater communication system that uses near-zero power to transmit sensor data.

Watch: World’s longest wind turbine blade is now in UK

The world’s longest offshore wind turbine blade has touched down at the Offshore Renewable Energy (ORE) Catapult’s testing facilities in Blyth, Northumberland. The 107-meter LM Wind Power blade is  a milestone for the wind industry.

Why do ships use ‘port’ and ‘starboard’ and not ‘left’ or ‘right’

As port and starboard never change, they are unambiguous references that are independent of a mariner’s orientation, and, as a result, mariners use these nautical terms instead of left and right to avoid confusion. As NOAA informs, when looking forward, toward the bow of a ship, port and starboard refer to the left and right sides, respectively.

‘Norwegian Encore’ to leave the dock within August

Norwegian shipbuilder Meyer Werft announced the imminent launch of Norwegian Cruise Line’s newest cruise ship, expected in the morning hours of 17 August 2019.  Once Norwegian Encore has left the dock, it will berth at the shipyard’s out-fitting pier to be fitted with its funnel cladding.

Watch: Float to survive in cold water

The UK’s Royal National Lifeboat Institution (RNLI) published a video advising what one can do and can act to float on water and not drown. Following its ‘Respect the water’ campaign, falling into cold water shocks the body.

Watch: Saildrone, the first unmanned system circumnavigates Antarctica

Saildrone, a seven-metre long, wind-powered unmanned surface vehicle (USV) is the first unmanned system to circumnavigate Antarctica. The vehicle, also called SD 1020, had climate-grade sensors installed, and had gathered data in previously unchartered waters, providing an additional insight into ocean and climate processes.
