A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from run of river or tidal estuarine sites. Certain types of these machines function very much like underwater wind turbines, and are thus often referred to as tidal turbines. They were first conceived in the 1970s during the oil crisis.

  • Une hydrolienne est une turbine hydraulique (sous-marine ou à flot) qui utilise l'énergie cinétique des courants marins ou fluviaux, comme une éolienne utilise l'énergie cinétique du vent. La turbine de l'hydrolienne permet la transformation de l'énergie cinétique de l'eau en mouvement en énergie mécanique qui peut alors être convertie en énergie électrique par un alternateur. Les machines peuvent prendre les formes les plus variées allant du gros générateur de plusieurs mégawatts immergé en profondeur dans des spots à très forts courants de marée au micro-générateur flottant équipant des petits courants de rivière. Dans les années 2005-2010, la volonté de développer les énergies renouvelables met un coup de projecteur sur les énergies marines et sur l’énergie hydrolienne. La maturité technique du secteur s'affirme et les investissements financiers se mettent en place. Soutenues par des politiques institutionnelles volontaristes, des études techniques et environnementales sont réalisées. Dans le même temps, démonstrateurs et prototypes sont testés en France et à travers le monde pour valider concepts et machines. Dix ans plus tard le constat est moins optimiste : contraintes techniques, réglementations environnementales et coûts d'exploitation élevés freinent le développement d'un secteur industriel encore fragile.

  • Generator arus pasang surut, sering disebut sebagai konverter energi pasang surut, adalah sebuah mesin yang menyarikan energi dari pergerakan massa air, terutama pasang surut, meskipun istilah tersebut sering dipakai dalam merujuk kepada masin-masin yang dirancang untuk menyarikan energi dari arus sungai atau tempat pasang surut. Jenis mesin tertentu lebih berfungsi seperti turbin angin bawah laut, dan sehingga sering disebut sebagai turbin pasang surut. Alat tersebut pertama kali dibuat pada 1970an saat krisis minyak. (in)

Tidal stream generators are the cheapest and the least ecologically damaging among the four main forms of tidal power generation. (en)
  • Un generatore a flusso di marea (in inglese: tidal stream generator, con acronimo TSG) è una macchina o dispositivo elettro-meccanico che estrae energia cinetica da masse d'acqua in movimento, per lo più correnti di marea. Attualmente le TSG cominciano ad essere studiate perché sembrano più economiche e meno dannose ecologicamente tra le modalità di sfruttamento della energia mareomotrice ovvero: "generatori a flusso di marea"; "barriere per le onde di marea" (in inglese Tidal barrage) e "energia dinamica delle onde" (in inglese Dynamical Tidal Power). La maggior parte delle turbine maremotrici assomigliano a una turbina a vento, più comunemente al tipo HAWT. (it)
  • Um gerador de corrente de maré, também chamado de conversor de energia maremotriz é uma máquina que extrai energia do movimento de massas de água, em particular de maré, embora o termo seja frequentemente usado em referência a máquinas projetadas para coletar energia do corrimento de um rio ou de pontos de maré estuaria. Certos tipos de maquinas do gênero funcionam de forma similar a aerogeradores e são por isso também chamadas de turbinas de maré. Ela foi concebida na década de 1970, durante a crise do óleo. Geradores de corrente de maré são o meio mais barato e menos ecologicamente prejudicial entre os principais tipos de extração de energia maremotriz. (pt)
