What class of water wheel do we have to work with?
So this is called an overshot water wheel. There are many types of water wheels, but the one at the museum is called an overshot water wheel - an old-fashioned design known for its inefficiency. The design relies upon the weight of the water and gravity to fall into the buckets of the wheel, and this motion and gravity cause the wheel to turn.
How do you guys calculate the power from the water wheel?
First we have to calculate the rotational kinetic energy generated from the turning of the wheel.
KE = 1/2 I(angular velocity)^2
KEf-KEi=Work
Work=I*alpha*theta
P=Work/Time
Then how much power do you need to light an LED?
Our idea requires three blue LED lights. According to the above chart, a typical blue LED needs about 3.8 volts and a minimum of 3.4 volts.
What mechanical and electrical systems are needed?
Our mechanical and electrical design systems requires the use of a series of belts, a rotating motor, a 12-volt generator, LED light bulbs, and some basic circuitry.
