Hypnotize Heat Engine(Thermoelectric motor)
The left side got colder by approximately 18 Celsius as shown in the picture because it is gathering white surface on the left metal plate. Also, there is a gyroscopic force acting from the spinning force on the whole system of the thermoelectric motor that moves on the table. Furthermore, since the picture is taken.

Teacher used the approximately the about the same amount of water from measuring from beaker to the water heater(first process not shown). Two cups were made of heat insulating material to prevent unnecessary heat transfer to the environment. At, first the boiling water didn't work even after waiting for at least 30 seconds for the motor to start spinning.

Setup for the very beginning of experiment.

Here is the thermoelectric motor that teacher hooked up a thermoelectric generator with a approximately 3V DC toy brushed motor. Along with the card-box on the bottom as the structure for the whole system to stay in place.

Setup for the first part: Cold ice water vs. warm water.

 Setup for Second experiment. Ice water in one and flaming torch ready to heat up other side.

In this picture, the thermoelectric motor is stabilized in the icy water cup and the other side is ready to be heat up.

The Flame torch vs ice water. The heat on the propane flame torch side can reach up to two thousand degree Celsius, and thus we can have a max deltaT in the most ideal situation of Th-Tc=2000-0=2000C for the thermoelectric motor to spin up the hypnotizing disk.

After approximately 5 seconds of waiting, the wheel start to spin, which is shown in the next picture step.

The wheels starts to spin in the counter-clock fashion and keeps on spinning at counter-clock fashion even after the flame torch is moved away. 

 Set up for #3 of the first experiment. We first cooled the hot plate first in warm water.

The hypnotizing's speed did not really change noticeably even when we tried to cool it down in the warm water.

 Then, we cooled it in the ice water.

When we changed the hot side to the cold side, we almost immediately see a slow down of the hypnotizing disk.

After the hypnotizing disk's speed slowed down, we put the the two plates of thermoelectric motor in opposite ways. 

The hypnotizing disk is spinning now in a clockwise fashion. with the now boiling water on the left cup and cold water one the right cup.

 Setup for #4 of first experimental demonstration. This part is similar in  effect similar to that of refrigerator using energy to cool the a system.

After the hooking up the wires to the toy dc motor. We hooked up right to red power wire and left to ground wire with a power of .33 volt and 1.00 amperes. 

The spinning force of the hypnotizing disk gives the gyroscopic force to make the whole system of the thermoelectric move to the right from the picture above. 

 From the setup of the second experiment, we found out

The Pressure Lifter with PV diagram

The first syringe has a leak in the system in the tubing part.

Drawing of setup.

All three pics show the complete overview of setup that has the syringe changed and fixed loss of pressure problem.

Teacher's Automated computer calculation of the integral.

Vector calculation used: vector AB and AC cross product and times by 2 =24.5cc*kpa which was similar to teacher's answer.

 Setup for question finding the area inside the parallelogram using cross product from math 280 of treating AB, AC, DC, DB as vectors and finding their magnitude divided by 2.

 Set up for Carnot cycle, replace pic for max carnot is 33percent realistically.

 Demonstration of the four stroke cycle using half cross-sectioned model
There are four stages in the engine cycle with a spark plug.
First stage is intake.

Here is the general setup of a intake part of the cycle which takes both air and gas into the piston chamber. 

 Second stage: compression of

The finger points to the first stage of the four-stroke setup as the cylinder inside expand and thus more moles and volume will be in the chamber. Then, for second 

 Third step: combustion(sparkplug)

In this picture, the sparkplug is then igniting the compressed mixture of air and fuel from the previous stage where air and sucked into the system.

 Fourth step, exhaust out.

3 variables to know for power of heat engine.
