WIND POWERS VESSELS
Wind turbines in vessels is not a new invention . Savonius Rotor was invented by a Finn , Sigurd Savonius in 1926 , almost 100 years ago . Operation of his invention is based on Magnus effect and Flettner law ; very familiar to people involved in sailing .
The same physics laws are prevailing in Windside turbine , born 1982 in Finland by Risto Joutsiniemi . Due to shape and some mechanical differences , Windside has many advantages over Savonius rotor , e . g . totally soundless operation and utmost durability producing energy also in storms .
After working over 40 years with Windside turbines , Mr . Jout siniemi describes that “ a long journey has been just as a day of small beginnings ; future is at sea ”. – Despite the growing interest today from building industry .
“ As Windside turbines are strong enough to face storms seen by lighthouse Le Four in France , or McMurdo base station in Antarctica , they surely can stand and produce safe electricity also on vessels ,” Mr . Joutsiniemi says .

Key Facts :
Windside is used by e . g . Harbours , light houses , vessels , research centres , telecom , radars Operates 2m / s up to 60m / s Specifically designed for low cut-in wind speeds and no cut-out at extreme wind speeds . Production also in storms . 25 + year offshore lifespan Built of heavy-duty reinforced fiberglass , marine-grade aluminium , hardened steel , fully galvanized frames , high-quality bearings , and sealed electronics . Up to 5 years maintenance-free Optional automatic lubrication system extends maintenance intervals to 5 years . Silent , vibration-free and safe Perfectly silent , less than 5dB . Balanced for zero vibration . Safe to touch at all speeds . Patented technology

Civil engineer Per Kavli and the company Green Ships in Oslo are behind the projects for designing boats using only renewable energy as energy source . Mr . Kavli says : “ Environmental requirement and regulations in maritime sector are under big changes . The whole shipping industry is looking for new power plant solutions and the ultimate goal is to obtain ZERO NOX and CO 2 emissions .
This has resulted in the use of some new fuel options : Hydrogen , ammonia , methanol , fuel cells and also LNG ( which is not really a fossil free option , but in some ways better than MDO ).
