Another very interesting new possibility for generating energy. What's also interesting is the brief mention inside the article about UK energy consumption being a third of US households. That is quite a difference and it's going to have to change in the future. Also inside is a link to a computer generated video of what it would look like underwater.
A completely new concept of underwater wave energy using a simple 7 ton kite turbine design has been developed by Minesto; which is a spinoff from the Swedish military and aircraft design firm Saab. The Deep Green underwater turbine captures the power of the ocean just like a kite in wind.
The system could generate 18 terawatthours of energy annually, enough to provide nearly 4 million British households with reliably green electricity every year. UK households now use about a third of what average US households use in energy.
