Simple But Genius DIY Generators

Electricity is a versatile tool that helps achieve many survival related goals. Heat, light, cooking, entertainment, communication, construction.

The applications are endless.

The best part is, building DIY generators does not require the intellect of Nicola Tesla.

Or even a degree in electrical engineering.

You can buy energy generators and have them installed on your property. Or you can build your own. DIY generators are extremely helpful tools. And they can even serve to increase the sustainability of your off-the-grid outpost.

Building your own generator is a skill that makes a huge difference in a “SHTF” situation. Even if you don’t plan to make a DIY generator today, just knowing “how” is a valuable skill to have at your disposal.

The Principals of Making Electricity

Before we get into the different DIY generators you can build, let’s s cover the general concept. Electric generator all share the same basic principles. So these are the truly important concepts to understand.

Any time you use electricity, you are using energy that came from somewhere else. Whether it’s a coal plant, running water, or wind, power comes from some other form of energy.

You convert one type of energy (wind, water, geothermal, combustion) into another (electricity).

So how do you turn the energy of moving water into electrical power stored in a battery?

No matter the exact DIY generators you intend to build, these two pieces are essential: The Stator and The Rotor.

The Stator is a stationary shell that houses the Rotor, which rotates inside of the Stator. The Rotor is filled with magnets, which, as they spin within the Stator generate electric current.

That current is captured within the Stator’s built-in coils and transferred to the storage unit.

Now, to store electricity generated by the Stator and the Rotor you need a battery.

There are many commercial batteries designed for the sole purpose of storing self-produced energy. Basically, the larger the battery, the more energy you can store.

If you plan on using your generator often, I would recommend getting a large battery. One with a significant amount of energy storage potential. Or even better yet, a bank of batteries connected in series.

If you just want off-the-grid electricity to charge a camera and flashlight, small batteries are perfect.

Building Homemade DIY Generators

There’s more than one way to skin a cat. Right? If you want DIY electricity, you can look to the sky, look to the sea, look in the ground, look in your garage…

The potential for electrical generation is everywhere.

This is good because no matter the situation, the possibility for electricity generation is there. You just need to understand how to harness it.

For this reason, I’ve compiled a very brief, but comprehensive list of DIY generators.

Atmospheric Energy Generator

Our atmosphere is full of this potential electrical energy waiting to be tapped. But that’s the challenge, how can you tap this energy for use and consumption?

It’s possible to generate small amounts of “free” energy but nothing I know of has been invented to do so at great scale. However, it’s a source of energy to keep an eye on because, in our modern world, new inventions are always being created and developed. Tutorial

Hand Crank Generator


I have a flashlight that requires no charging, and no changing batteries.

All you have to do is crank the handle until you have generated enough friction to power the thing. This is a basic type of hand crank generator, and the one that you can build is similar.

This electrical generation is like the bike generator. It converts human energy into electrical energy. In other words, you get out of it what you put into it.

If you need to conserve calories because food is scarce – a hand crank generator is a poor choice. But if you’re lost at sea and need to signal for help, having a hand crank generator for light is very helpful. It’s situational – hand crank generators are not your best option, but they will do in a pinch. Here’s a video on how to turn an old cordless drill into a DIY hand crank generator.
