Triton – The Affordable and Robust Wave Power Harvester

Mila Luleva — Mon, 22 Feb 2016 18:18:09 +0000

Triton system is the latest very promising development in the field of wave energy. Wave power, also often referred to as tidal power, has been an ‘on’ and ‘off’ topic over the last decade. Many technologies have emerged over the years, many of them have failed (mainly because of underestimating the power of the oceans), and of […]

Does Ocean Energy Mean Wave Power or Tide Power?

Benji Jerew — Thu, 11 Jul 2013 18:03:10 +0000

Another form of hydroelectricity being investigated involves the movement of the ocean. Here, consistency could mean the difference between wave power or tide power. Like the wind that drives them, ocean waves are intermittent. Thus, any wave power generators that have been developed suffer from the same problems that on- and off-shore wind power generators […]
