Affordable DIY Generators The Power Companies Don’t Want You To Know About…

DIY Generators

It would be impossible to list all the reasons to build a DIY generator.

Regardless of your reason, the goal is always to produce and consume your own electricity.

Now, living off the grid doesn’t require electricity. Human beings have survived worldwide for tens of thousands of years without it.

It’s possible to make camp and sustain yourself without electricity.

  • Instead of light bulbs, use candles.
  • Forget the furnace; use the heat from a fireplace.
  • Instead of an oven, use a wood stove and thick blankets.

You can make it with the right set of survival books and woodsman know-how.

But electricity makes life a lot easier, AND it makes life better.

For example, a refrigerator and freezer are very difficult appliances to live without in our modern society.

But electricity is a survival tool like any other. It’s just intangible and non-material. But extremely useful.

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.

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 an “SHTF” situation.

Even if you don’t make a DIY generator today, just knowing “how” is a valuable skill.

Motor Rotor 1The Principals of Making Electricity

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

Any time you use electricity, you use energy from somewhere else. Whether it’s a coal plant, running water, or wind, power comes from other forms 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 build, these two pieces are essential: The Stator and The Rotor.

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

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

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

Basically, the larger the battery, the more energy you can store.

If you use your generator often, I 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.

Small batteries are perfect if you want off-the-grid electricity to charge a camera and flashlight.

Building your own battery is possible. But I’d rather recondition an old battery back to life. It’s easier and less dangerous.

Building Homemade DIY Generators – 8 Best Solutions

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

The potential for electrical generation is everywhere.

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

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

1. The Bicycle Generator

I put this one first because it’s so simple.

By turning the gears (or wheel) of your bike, you turn it into a Rotor. So you can generate electricity and get a workout at the same time.

Need to boil some water? No problem, put in twenty minutes on the DIY bike generator, and you’re cooking!

Need a reading light? Pedal while you read, and you will have light for as long as you are on the bike!

Obviously, this requires physical labor. You won’t be heating a large household via a bike generator. But a bicycle generator is a healthy way to go if you need electricity for small, quick tasks.

You don’t even need a whole bike for this setup. You can build a DIY bike generator using old bike parts. So there is no need to dismantle your prized bug out bicycle.

2. Hydroelectric Generator

I will go ahead and call hydroelectricity the BEST option on this list. Because it’s reliable, it’s consistent, and it’s extremely effective.

Hydroelectric power has been in use for thousands of years. The ancient Greeks were first attributed to converting moving water into grinding wheat.

They were not using electricity, but they were harnessing energy. They turned running water into the useful task of making flour.

Which is exactly the concept behind generating hydroelectric power?

Water wheels are the most popular way of achieving hydroelectric energy. Positioning the wheel in the moving water transfers the motion of the water to the spinning wheel.

This wheel is then attached to the Rotor. And the energy is collected by Stator before being transferred to a battery.

Many streams and rivers flow at a near-constant rate. So hydroelectric energy is produced day and night, non-stop – effectively and efficiently.

Sadly, building and installing a functional hydroelectric plant yourself is complicated. Not impossible, but it requires a lot of foresight, preparation, and planning.

And, of course, you need a running body of water nearby too. So they’re not location independent, thus making them relatively rare.

3. Wind Energy

The wind is one of your next best DIY Generator options.

The basic idea is the same – large blades capture the wind’s momentum and transfer it to a Rotor/Stator setup.

Unfortunately, wind turbines present a problem for the average Joe. They usually require ongoing upkeep and maintenance.

That’s why most large-scale wind farms have a team of highly trained, highly skilled engineers. They’ve been trained specifically to manage these wind turbines. But it’s becoming easier.

The most important aspect of setting up a wind turbine is investing in an efficient Rotor/Stator setup. A turbine setup that allows you to capture as much of the wind as possible.

However, this only really works in windy regions. Wind doesn’t do you any good if you live in a place where the air is perpetually still.

You need a lot of consistent, reliable wind if you want your DIY wind-powered electric generator to pay off.

4. Hand Crank GeneratorHand Crank Flashlight

I have a flashlight that requires no charging and no changing batteries. It’s a hand-crank flashlight.

You have to 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 a 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.

5. Compost Heat Generator

How about generating heat from waste?

Now, heat is not electricity; heat is a form of energy and is highly useful.

It’s also exciting to be able to use compost materials (wood chips, grass clippings, mulch, hay, etc.) to generate abundant amounts of heat.

You can use heat to warm a small home, a greenhouse, or even a hot tub.

↓ Compost-Powered Water Heater ↓

The one caveat is you need to run a pump to circulate the water.

So while this setup creates heat, it takes some energy input to run.

6. 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 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.

7. Solar Power

Everyone knows about solar; many homes are either fully or partly powered by solar.

Now the sun’s rays are free, but collecting them and converting them into usable energy is not.

However, you can significantly cut the costs of installing a solar system if you understand how it works and how to build your own DIY Solar Power System.

  • No matter if you have no money to spend on a ridiculous off-the-shelf $20k system.
  • It doesn’t matter if you don’t have the time or patience to go through trials and errors.
  • No matter if you’ve never built anything before (not even an IKEA chair)

It’s simple, easy, and cheap – it’s possibly the best DIY generator solution on the market today!

8. Biogas Generator

The general idea behind a biogas generator is fairly simple. You need a source of organic waste such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, or food waste.

You then put these organic wastes into a large bin or tank called a digester.

In the digester, you fill it with a specific ratio of organic material and water.

As organic waste breaks down, it releases heat and gas.

This biogas can power a generator, which converts the cheap (often free) “waste material” biogas into electricity.

Survival Applications of DIY Electricity

It should be evident that electricity makes life easier. The quality of human life worldwide has skyrocketed once it became a common resource.

But for illustrative purposes, here’s a short list of survival applications of electricity:


First, electricity’s most significant survival use is the ability to generate heat. Especially during the winter months and in cooler regions.

Having a method to quickly and efficiently warm your shelter is an absolute game-changer.


With electricity, you don’t have to go through the trouble of starting a fire whenever you want to cook. Nor do you need to keep a large supply of dry firewood on hand (although I highly recommend it).

But life is easier using hot plates, electric skillets, toasters, or crock pots. All of which make meal preparation a lot easier.

It’s even more important to be able to cook food in a dire emergency scenario.


Emergency candles and gas lanterns have a nostalgic appeal and work in the shorter term. But we all know they’re not the most efficient or effective way to light a room.

Modern LED electric bulbs use very little energy and last a long time. There are also many rechargeable options for solar lanterns, flashlights, and lamps. This is efficient and safe for the environment.


Believe it or not, entertainment can be as valuable a survival supply as fresh food because it preserves your sanity -which is invaluable in a survival situation.

Heck, sanity is a valuable resource in any situation.

Charging a cell phone or a small radio can make miserable circumstances bearable.

Of course, a library of survival books and survival playing cards are also electricity-free forms of entertainment.


Cameras and camera equipment all use electricity and need batteries to run. So if you need to wait for a shot, you may have to use a small DIY energy generator to charge and power your equipment.

Torturing Your Enemies

Have you seen the movie Taken? Well, in it, Liam Neeson uses a car battery to torture and interrogate his daughter’s kidnappers. It’s pretty brutal – but man, it gets the job done.

Anyway, if you need a form of “enhanced interrogation,” electricity offers one.

The Final Word

Electricity is one of the most effective survival tools ever harnessed by man. It makes life on Earth easier.

We leverage it to accomplish an endless number of goals.

And the best part is the energy is everywhere – just waiting for you and your DIY generators.

Extract it from the wind, or the water, use your own physical power, or transfer it from another energy source.

If you understand the concept of collecting energy, you’ll go far. If you commit those principles to memory, you can build a generator from scratch almost anywhere.

Now that’s self-reliance.
