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.
The speed of travel of the deep water swell group will be 1.5 times the swell period; ie: a 20 second swell will be traveling at 30 Nautical mph. The actual individual waves will be traveling at three times the swell period, so a 20 second swell will have waves moving at up to 60 Nautical mph.
