How to start the box fan without electricity? (6 great ways)
Content
In this article, I will give you a bunch of options to run a box fan without electricity.
A box fan can be a lifesaver for those who live in hot climates. But what to do when the electricity is turned off, but there is no electricity? As an electrician and self-proclaimed DIY tinkerer, I'll share how I've done it before and share some of my favorite tips!
In short, these are viable ways to start a fan without electricity:
- Use solar energy
- Use gas - gasoline, propane, kerosene, etc.
- Use battery
- use heat
- use water
- Use gravity
I'll go into more detail below.
Solar Energy Option
Solar energy can be used to spin a fan without electricity. The process is simple. I will show you below:
First, get the following items: solar panel, wiring and fan - everything you need. Then, on a sunny day, take the solar panel outside. Connect the end of the wire to the solar panel (it should conduct electricity). Also connect the fan motor to the opposite end of the wire.
That's all; Do you have a solar-powered fan at home?
How to make a fan run on gas
Step 1 - Items You Need
- Get gasoline, diesel, kerosene, propane or natural gas
- Engine, engine, alternator and electric fan.
- A motor with electronic components (generator) that runs when heat is needed for the gas fan.
Step 2. Connect the fan to the engine or generator.
Connect two cables from the engine or generator to the fan terminals as shown below:
Step 2: Set up the engine or generator.
Now turn the generator switch knob to the "on" position and light it.
How to make the fan run on battery
Here you do not need many specialized tools; you only need the following:
Batteries, cables, latch, soldering iron and electrical tape.
Step 1. Which battery should I use?
Use an AA battery or a 9V battery to power the tiny fan. Even a car battery can be used to power a larger fan.
Step 2 - Wiring
The ends of each wire connected to the latch and fan must be stripped. Twist the red (positive) wires.
Step 3 - Heating up
Then heat them up and join them together with a soldering machine. Use the black (negative) wires in the same way.
Step 4 - Hide the Wire and/or Solder
Insulating tape should be applied over the soldering points so that neither the wire nor the solder is visible.
Step 5 - Attach the Snap Connector
Finally, connect the snap connector to the 9 volt battery. You currently have a battery powered fan that runs until the battery runs out.
How to control a fan with heat
You will need the following supplies:
- Stove or similar heat source
- Fan (or motor blades)
- CPU cooling fans
- cutting blades (scissors, utility knife, etc.)
- superglue pliers
- Peltier steel wire (thermoelectric device)
Step 1: Now arrange the materials in the following sequence.
Peltier > large CPU heatsink > small CPU heatsink > fan motor
Step 2: Connect the wires
The red and black wires must be connected as they are the same color.
You convert the heat from the stove into electricity to run the fan when it gets hotter.
How to use gravity to make a fan work
If you have something heavy, some chains (or ropes) and some gears, use them to create a fan rotation with gravity - a gravity fan.
Using gravity, one of nature's most accessible forces, you can create your own power source with this technique.
Step 1 - Connect the chains
Pass the chain through several interlocking gears. Some weights are held by a hook at one end of the chain.
Step 2 - Mode of action
Consider this a pulley system that uses gravity to create mechanical energy.
The gears are rotated by weights pulling the chain.
The rotating gears drive the fan.
How to use water to run a fan
Water can also be used to power fans. Requires water, turbine and fan. Water is converted into kinetic or mechanical energy by a turbine, essentially an impeller blade.
Running water turns the blades, passing through them and flowing around them. Rotational energy is the term for this movement. A fan connected to a water tank or other energy storage device is placed under or next to this device. The rotating turbine drives the fan. You can also use salt water to make a fan.
How to do it:
- Use a piece of flat wood as a base (about 12 inches is fine for a small fan).
- Glue a small vertical rectangle in the middle of the wooden base.
- Attach two ceramic cups to the base with glue (one on each side of the base)
- Attach the fan motor with glue to the top of the rectangular piece of base wood.
- Attach two copper wires with solder to the back of the fan (opposite side where you will be attaching the blades).
- Remove the frayed ends of the wires to reveal the copper wire underneath.
- Wrap the two ends of the bare wire with aluminum foil.
- Place the ends of the aluminum foil in two cups. Add two tablespoons of salt to each ceramic cup. Add light, thin plastic or metal blades to the fan motor. Then fill all the ceramic cups in the hallway with water.
The fan blades should begin to spin as you fill the cups, creating airflow. Essentially, the salt water becomes a salt water "battery" that stores and releases energy to run the fan.
