Hand cranked induction generator

In the hand cranked induction generator, a coiled wire was attached to a crank that was surrounded my magnets. When a person cranked the generator, they altered the angle of the coiled wire thus inducing a voltage. In an inductor, a change in current (in this case by altering the the current and thus the magnitude of the magnetic field) induces a "back" voltage to halt the change in current. The inductor always wants to be in a state of equilibrium and it does so by creating a "back" voltage. The induced current created by the "back" voltage powers the light bulb.

Solar Panel Exhibit

The solar panel consists of N and P type silicon. In the solar panel exhibit, light from the sun creates holes in silicon. The N form of the silicon possesses extra electrons, and those electrons want to move from the negative side of the silicon to the positive side of the silicon where there are more holes to fill. As the electrons rush to the holes, the positive and negative charges exert a repulsive force on each other thus creating voltage.

Lemon Battery

Today, we dealt with a different theme of physics: electricity. In the lemon battery, a chemical reaction takes place, and the copper penny's valence electrons move to the better conducting zinc screw. This change in electric potential creates a voltage. The current flows from a positive voltage, approximately 0.2 V, to a negative voltage, which is about zero.

Stirling Engine

Day 4:
Our Stirling Engine is starting to take shape. We need to connect the elbow to the base of the engine, and we need to RTV the two pillars as well. The two pillars will hold up the crankshaft.


Day 5:
Richard took the Stirling Engine home and glued the displacer and pressure valve in place. He also RTV'd the pillars and elbow to the base. We've placed a balloon on the elbow and have attached the balloon to the crankshaft. We need to check for leaks and find a way to attach the crankshaft to the pressure vessel.

Day 6:
Richard has leaked test the engine numerous times in his pool. We've applied tons of RTV to the places where bubbles appear during the leak test. Hopefully, all the leaks will be covered in time for the 3.5 floor deadline.

Day: 7
Richard purchased Sterno, so hopefully that large amount of fire power will provide a sufficient amount of energy.

Day 8:
The Stirling engine is not quick working. There is probably a leak. Additionally, things are starting to fall apart. My dad and I reconnected the crankshaft to the pressure vessel and tried patching up even more holes by applying RTV to every possible spot.

Day 9:
Stirling Engine doesn't want to seem to work. Dr. Philhour has told us to stop working on it. Despite the setback, we've have learned valuable collaboration skills for the future.
