yes i did stuff like that
A generator transforms mechanical energy into electrical energy.
A fuel ran machine uses combustion to obtain power, which therefore creates noise, an electrical machine uses the magnetic fields of electricity to obtain power which in return is silent, and there is the reason for the difference.
A magneto is an electrical power generating device which operates without the need for a battery to energize the coils. A magneto uses permanent magnets to induce an electrical current, which is "pulsed" Direct Current [DC]. These pulses are controlled [by "points" in the "old" days] to "time" the pulses to the coil primary winding coil, which the creates the high voltage ignition pulse which is delivered to the spark plug[s].
It would be possible if you have the proper testing equipment and electrical tools to do the job.
Sharp power pulses.
Electrical motors convert electrical energy into mechanical energy.
Einstein said that mass/energy can neither be created nor destroyed, but we can often convert the form from one into another. So it is possible to use a windmill and generator to convert the power of the moving wind into electrical current. Or, you can use a hydroelectric dam to convert the power of rain falling in the mountains into electrical power.
A power supply does not create power or energy. This would be in violation of the Law of Conservation of Energy. Rather, a power supply changes the form of an available source of power or electrical energy into a form that is acceptable for use by electrical or electronic equipment. The input form is electrical energy defined by voltage or current or power, with a given impedance level, and frequency. The output form from the power supply is a different voltage or current or power, with a different impedance level, and possible a different frequency. Another possible is for the input and output to be of the same form but electrically isolated from each other for safety and performance concerns.
Knots is a measurement of speed. Horsepower is a measurement of power. To obtain that speed on water is probably not possible. To obtain that speed in air takes allot of horsepower. That is over Mach 2 (twice the speed of sound),
Piezoelectric crystals generate electrical energy when bent or squeezed, so yes, it's possible.
Unless you have a background in elecronics or electrical engineering do not attempt to repair the power to your monitor.
they were looking to obtain as much power as possible
