Part 1: To start the experiment, we recorded the minimum voltage with no light coming on the solar cell. We exposed a solar cell to a light coming from a flashlight at different distances, first against the solar cell ( … Continue reading →

We used a flashlight with a coil inside as a generator. We connected the flashlight to a voltage probe, then the voltage probe to the computer. We recorded the voltage obtained with 0 shakes while 30 seconds. We have done … Continue reading →

Demand response ( also called load response) programs enable energy consumers to reduce the amount of power these use during moments of high energy demand ( in summer for example). Demand response programs are popular because participants in the program … Continue reading →

The objective of our second experiment with robots was to demonstrate the relationship between mass and accelaration (Newtown’s second Law), accelaration and power level, then power level and power, and finally battery drainage and mass. We program the robot with … Continue reading →

Natural gas hydraulic fracturing consists to make more gas flow for extraction by injecting a mixture of sand, water, and some chemicals into rocks The quantity of gas increases, because the fluid used to fracture rocks is high pressurized, so … Continue reading →

Gas mileage is the number of miles used by a car per a galloon of gas. Burning a lot of gas has a bad impact on the environment; it also contributes to the air pollution. Some policies about boosting gas … Continue reading →

In the last we did, we made a car robot, and programed it with Labview. The goal was to measure by two different methods (ruler method, and LearSmart program on the computer) the distance the car travels, compare those results, … Continue reading →

Germany is the biggest invest the most in the production of wind power after China, India, Spain, and the US; it is also the largest investor in new capacity in photovoltaic (PV) solar and biodiesel production, and the biggest in … Continue reading →
