Sorry, George - the "Pizeo" (more properly spelled
Piezo) ignition was meant to be a joke. But, some lawn
mower systems do have a small Piezo electric type ignition. This is the
making use of the property of some crystals which if flexed will generate an
electrical discharge. The lighter on most gas Bar B Q grills are Piezo
electric. Sorry if my misspelling mislead you.

Ed,
What is a Pizeo EIS?
George ( down under)
Rich, good questions, but like many of the choices we in
alternative engines face, there is no yes/no, good/bad- just
another risk factor with pros and cons to consider. I believe
that there is some technical merit to using an electrical water pump such as
reducing pumping HP losses, perhaps less weight, optimum coolant temp
control, etc. . You could also factor in your water pump
current load into your overall power considerations and run with a larger
battery to get you your minimum alternator-out time. But, I must admit
that I find the reliability and no need for attention mechanical pump
preferable for myself.
Me?, I'm waiting for a pizeo electric ignition
system and a mechanical fuel pump and then I can throw the
battery away {:>).

I have a potential safety question with using an electric pump,
unless the engine is using a magneto.
The ignition system runs on battery/alternator power. If it and the
FI are run by an ECU, it too needs power. The fuel pumps need electricity.
There are other electric hungry mechanism that need power.
In an alternator/battery failure (short of having dual alt and batt)
to have a water pump sucking 5 or more amps of power, this significantly
shortens the available flight time before engine stoppage.
If the engine is magnitoed, when the electrons disappear and the
pump stops, all that will happen is that the engine will fry---- The
result will be the same
