However exciting the rubber robot snake wave power generator sounds, a real seagoing power station is way more interesting. And over in the UK, they've just turned on the world's first commercial tidal power generator station. SeaGen is situated in Strangford Lough, Northern Ireland, and it has twin turbines that spin as the tide rushes into and out of the lough at up to 8 knots. The moving seawater spins the turbines for around 20 hours each day and when it's up to full operating capacity, SeaGen will be pushing out 1.2 megawatts of power, roughly enough to supply 1,000 homes. And since the revolution speed is only around 10 to 15 per minute, the blades shouldn't offer a threat to sealife like the local common seals. Eco-friendliness all 'round. [Daily Mail]
