The theory that substantial energy can be extracted continuously for 24 hours from the perpetual current of Florida’s Gulf Stream appears obvious to those who study hydrokinetics, yet until now the goal has been elusive.
Other forms of clean energy may seem to be similarly perpetual, but they are not. The wind blows, dies down and eventually gusts again. The sun rises and sets. Tides wash in and flow back out. The energy they create must be stored somewhere until the source cycles back on again.
Meanwhile, the Gulf Stream keeps flowing. A natural phenomenon throughout recorded history, it will be here for a long time to come. In certain sections, its velocity has been measured at more than 300 times the rate of the
