Water Baby is Energy Systems &
Design's solution to sites where the flow is very low, as low as 3 gpm
(0.18 l/s), and the head is above 100 feet (30m). It uses a double
stator, brushless permanent magnet generator with a 2" (50mm) pitch
diameter bronze turbine wheel. At a head of 100 feet (30m) and a flow
of 3 gpm (0.18 l/s) the output is 25 watts; at 24 gpm (1.5 l/s) the
output is 250 watts.
Water Baby is available either as a low voltage model (12/24 volt) or a
high voltage (48/120 volt) model. .
Electricity is produced from the potential energy in moving water from
a high point to a lower one. This distance is called "head" and is
measured in units of distance (feet, meters) or in units of pressure
(pounds per square inch, kilo-Pascals). "Flow" is measured in units of
volume (gallons per minute - gpm, or liters per second - l/s), and is
the second portion of the power equation.
The power available is related to the head and the flow. The Water Baby
is designed to operate over a wide range of heads and flows. Nozzle
diameters of 1/8 to 1/4 inch are available, and up to four nozzles can
be used on one machine, to utilize heads as low as 50 feet and as high
The Water Baby uses a permanent magnet type alternator. This design
eliminates the need for brushes and the maintenance that accompany them
while increasing efficiency. The Water Baby's output can be optimized
by simply adjusting the position of the stator.
