for example the equipment cost for a 10 kw wind turbine costs roughly $ 40000 while a 100 kw turbine can cost more than $ 350000 according to bergey com the average wind turbine can cost $ 48000 to $ 65000 to install
The boats can typically travel at speeds over 80 knots (150 km/h) in calm waters, over 50 knots (90 km/h) in choppy waters, and maintain 25 knots (47 km/h) in the average five to seven foot (1.5 to 2 m) Caribbean seas. They are heavy enough to cut through higher waves, although at a slower pace.
2.15 How fast can dolphins swim? The dolphin's fast cruising speed (a travelling speed they can maintain for quite a while) is about 3-3.5 m/s (6-7 knots, 11-12.5 km/hr). They can reach speeds of up to 4.6 m/s (9.3 knots, 16.5 km/hr) while travelling in this fashion. When they move faster, they will start jumping clear of the water (porpoising).
