Personal Energy
Systems Calculations: Part II
by Dennis L. Feucht
Innovatia Laboratories
In Part I, we did some basic calculations on the feasibility of using raised
and rotating (flywheel) weights to store energy, and how feasible it is
to reduce power usage so that some alternative generation and storage methods
might become feasible on a small scale, that of a household. In this Part
II the calculations continue for power from flowing streams of water and
from small- or medium-scale ethanol production. By putting numeric values
to the requisite equations, the feasibilities of various schemes is made
more apparent. This includes the reasons why the world is not bursting with
all kinds of alternative-energy generation and storage techniques. However,
as the older solutions become increasingly less attractive, these calculations
can guide the effort to select alternatives.
