This is incorrect because for it to work, it is necessary in addition to burning fuel (apart from all the embodied energy prior to its design) a not insignificant quantity of consumables (oil and various lubricants, mechanical maintenance) to operate. .and I do not even address the problem of the machine operator.
the "why" has a teleological connotation, cyclones organize themselves spontaneously when the flow of heat from the ocean to the atmosphere becomes too great, that's all .
No such connotation, it's just a question, you can replace it with how, but whatever.
I rephrase: what is the origin of this spontaneous organization?
