Here is a fun design.

Expand the air by heating with microwaves. Have a magnetron as the
"spark" plug.

ANd the only question of efficiency over electric moters is the
correct frequency.
A high microwave to air absorption efficiency would have a nice thirty
percent total efficiency!

So how do you calculate the absorption frequency? Go infared! And
use light bulbs.

Quite bad until water was added to cause the expansion. A frequency
for water vapor is slow. So a 2 gHz magnetron would work!

Water injection solves the "coupled"radiative transfer.

And so the only question is absolute total efficiency over electric
motors.

I believe a half a cycle is lost. So noninductive systems would not
loose an automatic half cycle to designer necessity.

A 3% gain means build it:)

1kw would heat to cause three inchs of piston travel in 1/10th
second. So the slow speed torque would have to be geared up.

A metallic coating on a literal injection molded block and head would
be the style to think about. A rubber oring would last the duration.
And slight oiling would ensure the emisison. Water is NOT recyled! It
must spit out the tail pipe.


5 gal is good for the battery power cycle.
