  2. Several Different Ideas Current Ideas: • Pelton Wheel • Computer Fan Less Current Ideas: • Drill Water Pressure • Multiple Layers of Blades • Last Year(Aquarium Water Pump Wheel)

  3. Pelton Wheel The most difficult and promising idea is to use a Pelton Wheel. Shown here: Click here to see a Pelton Wheel as a micro hydroelectric power generator: http://www.youtube.com/watch?v=sDVQaul_w7Q&feature=related

  4. Pelton Wheel • For the Pelton wheel idea, we will use an old alternator to produce the electricity. • We will take several spoons and weld them onto the pulley of the alternator in order to achieve a higher efficiency.

  5. Computer Fan For this idea we removed a small computer cooling fan, bought and cut lengths of pipe and threaded rod, we are using bearings to minimize friction, and soon we will focus the energy of the water to direct the flow of the water to the fan blades. To view how this device works: http://courseweb.lis.uiuc.edu/~rpeters4/NPRE201/P1060160.MOV

  6. Computer Fan We have had some success with this method. However the speed has not been adequate yet. We are working on optimizing the efficiency of this system by focusing the energy and flow of the water. But to see the progress made so far: http://courseweb.lis.uiuc.edu/~rpeters4/NPRE201/P1060165.MOV

  7. Calculations • To check the efficiency, we will to compare the theoretical and actual power of this system. • To get the actual power output, we will use a DMM as a voltmeter in order to check the voltage out of the alternator. As well as using a resistor and the DMM as an ammeter, using these two measurements and Ohm’s Law we can calculate the power output in Watts. • This can be compared to the weight of the water and the height to calculate the theoretic potential energy and thus the kinetic energy. This gives us the energy in Joules. Then by calculating how long it takes to run out of water. One watt is a joule per second. So this is another easy calculation.
