"I wonder if he mightn't have some idea of what else plutonium can be used for, beside generating power."
It is exactly like the primary battery in the fundamental circumstance that its ability for generating electric current depends upon chemical action.
These polyps have a unique generating mechanism that reproduces them via the budding process, and they have an individual existence while also participating in a communal life.
An experience, a very humble experience, is capable of generating and carrying any amount of theory (or intellectual content), but a theory apart from an experience cannot be definitely grasped even as theory.
The swinging pendulum, with connected apparatus for compressing air or, perhaps, for generating the electric current, seems to be the most controllable and therefore the safest of the various types of apparatus which are applicable to the utilisation of wave-power for propulsion.
