A portable generator is a convenient way to safely produce your own power when the grid goes down, either due to natural or man-made causes. But how does a generator work? Whether you’re new to using a generator, or well-experienced, there are a few things you need to...

Now's your chance to do a little maintenance. You can carefully clean the grooves of the pulleys with a wire brush to get any old rubber bits and grime out of the grooves where the belt sits. You can also inspect the belt for wear [Source: AutoZone]. Most belts will need to be rep...
The rotor is a series of large electromagnets that spins inside a tightly-wound coil of copper wire, called the stator. The magnetic field between the coil and the magnets creates an electric current. In the Hoover Dam, a current of 16,500 amps moves from the generator to the transformer,...
When attempting to replace the samsung washer drum bearingmachine on their own, “Homemade” repairmen sometimes make mistakes that complicate the repair and result in additional charges. What exactly are these blunders? Severing the wire that connects to the sensor, which prevents the hatch from...
Your backup system should have enough output (in kW) to handle the momentary spike in power that heat pumps pull when they first turn on. You can find it on a heat pump spec sheet, expressed as the locked-rotor amperage (LRA). If the generator or battery can handle that initial jolt,...
I gave it a real test by chucking it up in my drill press and connecting it to a dummy load. It works great as a generator, putting out easily a couple hundred Watts with this setup. I knew then that if I could make a decent set of blades to drive it, it would produce plenty ...
(your utility bill conveniently lets you know how much energy you use every month), there are simple methods you can use to determine just how many PV modules you'll need. You'll also need to decide on a system voltage, which you can control by deciding how many modules to wire in ...
In Michael Faraday's generator, coils of copper wire rotating between the poles of a magnet produce a steady current of electricity. One way to rotate the disk is to crank it by hand, but this isn't a practical way to make electricity. Another option is to attach the shaft of the gene...
