Introduction
The pursuit of free or cheap energy has been a dream of man for
years. One idea that has always interested me is to convert
mechanical energy or kinetic energy to electrical energy. By using
the flow of water to provide the kinetic energy necessary to create
induction in a generator, we can create electrical energy. Many of
these generators already exist, they are called hydro generators. The
Hoover Dam is a well-known generator which provides power to a
large area. I do not have the space and the resources to build a
generator to that scale, so for the purposes of my project I plan to
build a generator on a much smaller scale so that it can be portable.
Having a generator that is portable gives the possibility for campers
or outdoor types, to have energy in remote areas.
Results
My first test was to compare the voltage output to the rotation per
second. Dealing with the problems described earlier I was able to find
at 0.88 revolutions per second I could achieve .2 volts and at 1.66
revolutions per second I could achieve .3 volts. I also tested to see if
I put two magnets per series, how it would affect the voltage output.
Though this provided much more difficulties with the stability of the
brake rotor because of the extra strength in the magnetic field, I was
able to find that at .93 revolutions per second I achieved .4 volts. I
was looking for more voltage output, but from what I learned in this
design I have developed a new design.
Discussion
After I finished my testing I found lots of design flaws that kept my
generator from getting to its highest potential. From this I was able
to come up with a new design, which I began calling my beta
design, which I hope to fix many of the problems. The rotor part of
the generator would be a cylinder that is 4 inches high and 4 inch
circumference. This would reduce the wobbling that the current
generator has. The magnets would attach to the outside of the
cylinder, where the magnetic field would go horizontal. The stator
would sit around the cylinder, where the coils wrap around metal
rods facing the magnets to add eddy currents to the system. With
wrapping the coils around something will help with the how many
turns I can put in each coil. I would also add a lower bearing to
help with stability. I plan on building my new design sometime in
the future. I am very interested in finding out what the maximum
output possible for a generator of this size.
