Model elbow engine converts back and forth motion into rotary motion without gears.
POPULAR MECHANICS Jul 1965 (v.124#1) pg. 166

Make a model tesla turbine. Runs on air or steam.
POPULAR MECHANICS Sep 1965 (v.124#3) pg. 188

Sea engine pumps sea water using magnetic fields. Model engine demonstrates the action.
POPULAR SCIENCE Jan 1966 (v.188#1) pg. 114

A law of physics, the Joule effect, is that rubber tends to contract if heated. Two devices are shown to demonstrate this. (1) A simple pointer attached to a rubberband and (2) a Joule-effect engine which is a large disk with many rubberbands which rotates when exposed to heat.
POPULAR SCIENCE Jan 1972 (v.200#1) pg. 94

Spool motors. A wind-up device with just three moving parts.
SCIENCE PROBE! Nov 1992 (v.2#4) pg. 110

Five engines that are driven by the heating of rubber bands (the Joule Effect).
SCIENTIFIC AMERICAN Apr 1971 (v.224#4) pg. 118

How to construct an ultrasimple heat engine that has only one moving part.
SCIENTIFIC AMERICAN Jul 1971 (v.225#1) pg. 114

Mechanochemical turbine, designed by Martin V. Sussman, rotates as smoothly as an electric clock, but energy is provided through a process similar to the contracting and relaxing of muscle fibers. A collagen fiber is passed through brine and fresh water, thus contracting and expanding to produce rotational force.
SCIENTIFIC AMERICAN Apr 1973 (v.228#4) pg. 112

The amateur scientist. Experiments with the external-combustion fluidyne engine which has liquid pistons. A close relative of the solid-piston Stirling engine. Useful as a laboratory or workshop aid in studying aspects of thermodynamics. Might also be suitable as an inexpensive pump for irrigation.
SCIENTIFIC AMERICAN Apr 1985 (v.252#4) pg. 140

Wire that "remembers" its shape is put to work running an engine. Designs for a Nitinol-wire thermoturbine.
SCIENTIFIC AMERICAN May 1986 (v.254#5) pg. 124
