From Ice to Steam and Vice-versa, overcoming IMF. For phase change to occur as shown in the heating cooling curve below, matter must be separated from each other. To separate matter among each other, the forces that keeps them together must be overcome.
The title for world's largest offshore wind turbine was held by Samsung Heavy Industries' S7.0-171 7-MW turbine, which is now being installed offshore at Fife, Scotland. Here's a roundup of other large offshore wind turbines which were on display at last fall's EWEA Offshore 2013 conference and expo.
This wind turbine had an annual capacity factor of 32% which is close to the modern wind turbines. The first megawatt wind turbine was installed early 1941 in Vermont. However, after 1,100 hours of operation this wind turbine failed but it was not repaired due to limited resources during World War II.
