By 2020, Scotland expects to power 750,000 homes with commercial-scale wave and tidal power
Discover Magazine has a slideshow of the wave and tidal devices that will be used, such as the pictured tidal turbine.
PS These devices do not include Scotland’s vast potential amount of offshore wind power. That’s a whole separate subject.

Tidal power turbine unveiled for Bay of Fundy
Nova Scotia Power plans to test the 1 MW turbine, which is 10 meters in diameter, for a year to assess environmental impact and durability. It sits on the seabed and generates power from the strong tides there.
Pulse Tidal. Next-gen tidal power
A flat, foil type device can be used to generate power in much shallower water.
Traditional designs use a rotating blade to extract energy from the moving water. The diameter of this blade is limited by the water-depth and this reduces the amount of power that can be generated in shallow water.
Pulse Tidal’s technology overcomes this [...]
South Korea to get world’s largest tidal power site
Sixty 300 ft. tall turbines on the sea floor will power 200,000 homes by 2015. The turbines are in deep water, where the environmental impact is less.
Tidal power agreement promises commercial products by 2012
Alstom Hydro, a huge energy company, has signed an agreement with Clean Current Power Systems of Canada to commercialize tidal power products by 2012.
Ocean Power Magazine has the details, including:
Tidal stream power technology presents numerous advantages to the environment. It is clean, natural, invisible, and does not emit any greenhouse gases. Moreover, being a 100% [...]
Tidal and wave power is expensive
Tidal and wave power remains a pricey way of creating power. The ocean is a rough place to site energy generation, and then there’s the question of getting the power to shore reliably. Salt, corrosion, and water turbulence takes a toll.
There’s plenty of R&D going on in tidal and wave power. Hopefully someday soon they’ll [...]
Tidal power development continues
Several major tidal power projects are continuing. Sure, there are lots of technical hurdles, but if (and hopefully when) tidal power becomes a mature, dependable technology, we will have enormous amounts of renewable power at our disposal.
New design for deep water tidal power

This new design from TidalStream for tidal power turbines claims to output up to 10MW per 6 turbine platform, substantially more than other designs. Plus, such power is generated completely silently and is not visible from the shore, which should keep NIMBYs happy. Let’s hope it can scale to commercial levels.
Tidal power from giant rubber snake
Testing is underway in the U.K. on ‘Anaconda’, a giant rubber ’snake’ that converts tidal wave energy to electricity. A full-sized Anaconda could reportedly power 1,000 homes.
Planetizen has more. This is amazing stuff indeed.
Scotland making huge push toward wave and tidal power
The turbulent seas off Scotland could product massive amount of tidal and wave power. However, the industry is still in its infancy, with technical issues and financing sometimes being problematic.
However tidal power is steady and consistent, a major advantage. The WSJ details the promise and the problems with articles, images, and video.
Coast Guard to test tidal power in Maine
The 6-knot currents and 20-foot tides in Eastport, Maine will be harnessed in a Coast Guard test to provide power for their station there.
A major advantage of tidal power is that the power generation, unlike with wind or solar, is steady and can be predicted way in advance.
Tidal power could create electricity on land, not underwater
Rather than creating the electricity underwater then send it to land on expensive, easily corroded underwater cables, this new tidal power system from NASA “uses water motion to generate a high-pressure liquid rather than electricity. That liquid is then transported to shore and used to produce electricity on land.”
Tidal power turbines
Atlantis Resources of Singapore has tidal power projects planned in Scotland and Australia. The Scotland project could eventually output 1GW, as much as a large coal plant, of clean, renewable energy. Huge data centers housing tens of thousands of computers may be built there, with the electricity coming from tidal power.

Maine gets grant to study tidal power
Video: Ocean Renewable Power successfully tested a submerged turbine during one of the roughest winters in decades in Maine
A nearly $1 million federal grant to UMaine and Ocean Renewable Power will be used to determine if submerged turbines can reliably create power from tidal currents in estuaries.
Maine has huge potential for tidal power and unlike [...]
