So how much power is swirling in Hurricane Ike right now? With Gustav last week and Ike this week and possibly Josephine a few days hence, the destructive power of nature’s howling winds is on more than a few minds! Googling for the answer, I discovered several sources that have calculated that, while it is extremely difficult to compute the power of a single hurricane, it is estimated its power is equivalent to 400 twenty-megaton hydrogen bombs (8000 megatons, or 8 billion tons of TNT).
