Effect of % Oil on Freezing Point Experiment 11 Results PCM-Oil Mixtures 10 Freezing Temperature (°C) 9 Thermocouple resolution is only precise to 1°F and readings varied greatly depending on where in the 8 mixture temperature was measured. Luckily, a linear approximation seems to be appropriate as there should be no physical reason for higher order behavior. 7 6 0 2 4 6 8 10 % Oil by Mass

Main Project To design and build an improved demonstration device to more clearly show that a phase change material can accomplish work.

Idea #1: Pinwheel Channel PCM through a tiny peephole and turn a micro-waterwheel

Idea #2: Syringe Drive a rack-and-pinion using a PCM hydraulic piston

Takeaways • Things almost never go right the first time. • Having curiosity and a willingness to ask questions is the quickest way to learn. • Work does not have to be the dull grind it is often made out to be.
