I found this a while ago, appeared interesting (particularly that I have spare magnetrons lying around), yet something about it seems a bit spurious.
I'd considered building it.
Have any of you experimented with this sort of thing?

Someone sent me a hard copy of this and I transcribed it. May make for some
fun experiments connected with cavitation, steam, and O-U.

I am posting the following for a friend who does NOT have access to Internet.
Comments welcomed.
NOTICE
The prupose of this notice is to place into public domain something which I
invented so that it may be patented and in order to prevent it's use from
being restricted in any way.
The device is an engine in which small quantitites of water are turned into
steam by the use of a magnetron (as found in microwave ovens).
Interested parties may wish to try this test: Place a few drops of water into
a clear plastic 35mm film roll holder and put the cap on the film roll holder.
Place in a microwave oven and turn the oven on. The 'pop' is the result of
the water turning suddenly into steam.
The engine I have invented is far more efficient than any other steam engine
because the efficiency of the magnetron in turning water into steam. In fact,
the water droplet 'explodes' very much like air/gasoline explodes in a
conventional internal combustion engine.
This engine was first tested in 1992. I am however unable to invest the
required capital to produce a more sophisticated model and therefore unable to
patent it. Even though I may not be able to profit from this technology, it
is too good to be kept to myself and I would like to spread it around so that
others may be able to use it.
The following is an outline of how to construct the device and a few cautions:
PARTS NEEDED:
1. Magnetron from medium power microwave oven.
2. Small 4-stroke single cylinder lawn mover engine or similar engine with
'old style' points and ignition system.
3. Automotive alternator with built-in rectifier and regulator, also a 12
volt auto battery.
4. "Trigger" mechanism from an aircraft "strobe" landing light.
INSTRUCTIONS:
1. The magnetron fits into the spark plug hole.
2. The distributor points are modified so that the contact is closed when the
piston is at the top dead center and this contact is used to activate the
aircraft strobe mechanism.
3. The high voltage from the strobe is connected to directly fire the
magnetron which in turn produces steam which moves the piston.
4. The engine turns the alternator which keeps the battery charged, which
supplies the electrical power for the magnetron.
CAUTION AND TIPS:
WARNING!!! DANGER!!!!
1. Be careful around the magnetron. KEEP IT SHIELDED WITH METAL. IT CAN CAUSE
SEVERE BURNS THAT MAY NOT BE READILY VISIBLE WHEN THEY FIRST OCCUR.
2. The 'strobe' trigger delivers a very high voltage which can jump to ground.
WEAR RUBBER SOLED SHOES AND INSULATE WELL.
3. Be sure to modify the distributor points so they close at the top dead
center. Timing advance depends on the power of the magnetron used and the
amount of water. Try different carb jet sizes -- drill out if needed.
4. Due to variables, don't expect high engine speeds without a little
experimentation due to variables.
5. Start with a fully charged battery or your alternator won't work.
6. The energy produced is in excess of the power required to run the
alternator but until you get the RPM up, and the parts wrking in harmony, it
may be best to use a battery charger instead of an alternator.
7. An easy way to measure net power output after you have the alternator on
line is to run a few 12 volt lights from the battery. You will see that the
battery stays charged even with the lights on and the motor keeps on going.
8. Although I have not tried it, the idea of vaporizing water with microwaves
should also work well in a converted turbine.
