This power can not be called "tidal" because it receives energy from sea currents, not the fastest (1 m / s). The power plant consists of a group of units, each of which represents something like a kite, just floating in the water column. Unit is positioned so as to optimally use the energy flow.
Each unit is equipped with "wings" with a total span of three meters, and the turbine, which drives the water. By the way, the cable, which "hangs" unit, a complex consisting of fasteners, cable ties and energokabelya.
Manages all of this operator, which monitors the performance of each unit, and directs them so that overall efficiency is maximized. The author of the project is Minesto. By the way, as long as it is - a pilot project.
Subject to the successful testing of the entire plant, the work will be introduced to the full-size units "wingspan" of 8-14 meters. Power unit with the "scope" in 8 meters
be 120 kW, at a flow rate of 1, 3 meters for second. 14-meter version will have to give 850 kW, at a flow rate of 1, 7 m / s.
The developers claim that their technology is quite competitive (including, and price) with other energy technologies, not only "green", but also traditional.
