Connect your mobile phone to the charger with the USB cable and place your wind turbine in a windy spot. Wait for the breeze to pick up.
As you can see in the video, the wind turbine rolls at a slow speed when the wind speed is low. However, the charger appears to be in good working order.
According to the results of the practical experiment, connecting the charger to the wind turbine charges the phone faster than connecting it to a modest solar panel, which is what I did previously.
Is it possible to charge a phone with a wind turbine?
We’ve seen portable charging solutions for personal electronics, vertical axis wind turbines, and now a combination of the two. That’s right, appropriate technology enthusiasts: a portable wind turbine is on the way, and it’ll be ideal for powering your electronic gadgets.
Skajaquoda is a Minnesota-based research organization dedicated to inventing items that help restore the balance between humans and nature. To that purpose, they created Trinity, a portable vertical axis wind turbine, and started a Kickstarter campaign to make it available to the general public.
Trinity is a portable wind turbine, to be precise. Any USB device, such as a smartphone or tablet, can be charged with it. It includes a 15W generator and a built-in battery capable of holding 15,000 mAh and folds up into a 12″ cylinder that can be carried wherever you go (enought to charge a cell phone up to six times). It was created with simplicity in mind, making it very easy to travel and operate.
I’m sure we raised a few eyebrows when we said that personal renewable energy generators would be enough to stop climate change, and yes, we acknowledge that more is required. This type of device raises awareness of the significance of weaning ourselves off of fossil fuels and reminds people of the need to develop renewable clean energy sources if we are to prevent climate change.
We recently covered the pedal-powered Bicycle Generator and its ambitious promises that one hour of riding could power a house for a day, which is simply not true. Small gadgets like the portable wind turbine, pedal-powered washing machine, and pedal-powered bike generators, on the other hand, keep the discussion on course, even if they only offer a chance for myth debunking! And if you live off the grid, technologies like this become second nature.
So pedal-charge your devices, or wind-charge them if you want, and then go out for a beer and charge your phone with the Stirling phone charging coaster, and tell us what you think of these technologies!
Is it possible to charge a battery with a wind turbine?
We frequently receive inquiries regarding why dump loads are required on wind turbines and how to determine the proper dump load(s) for a given system. The first section of this article will discuss why dump loads are utilized on wind turbines, and the second section will go over how to figure out which dump loads will work best for your system.
First and foremost, please notice that the terms “diversion load” and “dump load” are synonymous.
Why is a dump or diversion load necessary?
When running, wind turbines are meant to be loaded. The load on a wind turbine is nearly always an electrical load that draws power from the turbine’s generator. A battery bank and an electrical grid are the two most typical loads for a wind turbine. Although many of you reading this post are probably aware of this, it is critical to realize that an electrical load (such as a battery bank or the electric grid) keeps a wind turbine within its designated operating range.
Let’s use a hand drill on a piece of wood as an example to truly drive this concept home. The hand drill represents a wind turbine, and the wood represents an electrical load in our comparison. If you put the hand drill to its greatest power level and let it spin in the open air, it will probably spin at around 700 rpm. Because the drill isn’t doing any work, this is known as a “no load” condition. What will happen if we use the hand drill’s highest power setting to begin drilling a hole in the wood? When compared to spinning in free air, the hand drill’s rpm will definitely slow down significantly. This is due to the fact that the drill now has to work extra hard to bore a hole in the wood. This is what is referred to as a “laden circumstance.” A drill is now built to run with no load, while a wind turbine isn’t.
In high wind conditions, a wind turbine that is not loaded can self-destruct. Wind turbine blades can spin so fast under strong winds with no load that they can rip off or, at the at least, exert extreme pressures and strains on the wind turbine components, causing them to wear out quickly. In other words, when a wind turbine is loaded, it runs safely and properly.
Wind turbines are typically utilized to charge battery banks or feed an electrical system, as previously indicated. Both of these applications required dump loads, but let’s take a closer look at the battery bank application.
A wind turbine will keep charging a battery bank until the bank is completely charged. This is around 14 volts for a 12 volt battery bank (The exact fully charged voltage of a 12 volt battery bank depends on the type of batteries being used). Once the battery bank is fully charged, the wind turbine must stop charging it since overcharging batteries is dangerous for a variety of reasons (i.e. battery destruction, risk of explosion, etc.) But wait, there’s a snag! We must maintain an electrical load on the wind turbine! A diversion load charge controller is utilized to perform this purpose.
A diversion load charge controller is essentially a voltage sensor switch. The voltage of the battery bank is constantly monitored by the charge controller. When the voltage level in a 12 volt battery bank hits around 14 volts, the charge controller detects this and disconnects the wind turbine from the battery bank. A voltage sensor switch is a diversion load charge controller, as we previously stated. So, in addition to disconnecting the wind turbine from the battery bank, a diversion load charge controller can also switch the wind turbine’s connection to the diversion load! And the diversion load charge controller performs exactly that, keeping the wind turbine at a steady electrical load.
The charge controller detects a slight reduction in battery bank voltage (about 13.6 volts for a 12 volt battery bank) and turns the wind turbine back to charging the battery bank. This cycle is repeated as needed to prevent the battery bank from overcharging and to keep the wind turbine running.
How do I figure out how many dump loads I need?
Now, in order to determine the proper size of your dump load system, you must first ask yourself the following questions: (1)What is my system’s voltage (12 volt battery bank, 48 volt battery bank, 200 volts?) (2) At full power, how many amps will your wind turbine produce? You can continue on to the next phase after you have this information.
We’ll need to do some math and apply Ohm’s Law in the next few phases. Let’s use a real-life example instead of generalizations. Our Windtura 500 wind turbine will be used to charge a 24 volt battery bank in this demonstration.
26 amps is the answer. (We can see this from the Windtura 500’s reported power curve.)
Step 3: The dump load mechanism must be capable of dumping the wind turbine’s maximum output power. Power equals Volts x Amps, according to Ohm’s law. The voltage of the system is the voltage of the battery bank (We are going to use 29 volts which is roughly the voltage of a fully charged 24 volt battery bank). The current produced by the Windtura 500 at maximum power is measured in amps (26 amps).
Step 4: We’ll need a dump load capable of discharging at least 754 Watts. In this example, we’ll use our 24 volt dump load resistors. The internal resistance of these resistors is 2.9 ohms. We need to determine out how much electricity this resistor will consume, knowing that it is 2.9 ohms.
Step 5: Work out how much power a 2.9 ohm resistor uses:
Using Ohm’s law, Voltage = Current x Resistance, and some basic algebra, we get the following equation:
(Battery bank voltage)/(Resistor’s resistance) = (29 volts)/(2.9 Ohms) = 10 amps Current = (Voltage)/(Resistance) = (Battery bank voltage)/(Resistor’s resistance) = (Battery bank voltage)/(Resistor’s resistance)
Now we know that one of these resistors will draw 10 amps of electricity at 29 volts (battery bank voltage). What is the power consumption of the resistor?
We all know how simple it is:
(Battery bank voltage) x (amps through resistor) = (29 volts) x (10 amps) = 290 Watts Power = Volt x Amps = (Battery bank voltage) x (amps through resistor) = (29 volts) x (10 amps) = 290 Watts
As a result, one of our WindyNation 24 volt dump load resistors will be able to handle 290 Watts. Important: Make sure the dump load you’re using is rated to withstand 290 Watts at continuous duty at this point, or there could be a serious fire hazard. The WindyNation 24 volt dump loads can carry up to 320 Watts of continuous power, thus they’ll be perfect for this job.
Step 6: Connecting a 290-watt dump load resistor to a 754-watt load:
If you read Step 3 again, you’ll see that our dump load system must be capable of dumping at least 754 Watts. What can we do with a 290 Watt dump load resistor to accomplish this? That’s a piece of cake! The dump load Wattage is cumulative if numerous 290 Watt dump load resistors are wired in parallel. As a result, we have the following simple equation:
Total Watts required for our dump load system = (290 Watts) x (number of 2.9 Ohm resistors required in parallel)
Also, solve the following problems using simple algebra:
We can’t utilize 2.6 resistors because our resistors only come in whole units. We must round up because we require AT LEAST 754 Watts. As a result, we’ll need to connect three WindyNation 2.9 Ohm resistors in series. This gives us a dump load capacity of 870 Watts. We’ve now put up a dump load system that’s appropriate for the wind turbine and battery bank we’re using in this scenario. Any wind turbine system can benefit from the same conceptual process (Steps 1-6).
We hope that this post has shown why dump loads are required for wind turbines and how to determine how to set one up for your specific system.

What is the definition of a micro wind turbine?
Small wind turbines, also known as micro wind turbines, are utilized for micro-electricity generation rather than big commercial wind turbines like those found in wind farms. Passive yaw systems are more common in small wind turbines than active yaw systems. Larger turbines have geared powertrains that are actively aimed into the wind, whilst smaller turbines employ a direct drive generator and a tail fin to point into the wind.
Small wind turbines normally produce 500 W to 10 kW of power, but they can be as small as a 50 Watt auxiliary power generator for a boat, caravan, or micro refrigeration unit, and the Canadian Wind Energy Association (CanWEA) classifies “small wind” as high as 300 kW. Small wind turbines are defined by the IEC 61400 Standard as wind turbines having a rotor swept area of less than 200 m2 that generate at a voltage less than 1000 V.c. or 1500 Vd.c.
Is it possible to charge an electric car with a wind turbine?
The worldwide automobile industry is working for the creation of cars that generate fewer or no hazardous pollutants, use alternative fuels, or have regenerative technology, and have low operating costs. This is where electric vehicles enter the picture. Solar-powered vehicles and vehicles with regenerative braking have been among the many advancements (generating energy every time brakes are applied). And the most recent breath of fresh air comes from Colombia, a South American country…
Colombia’s only domestic car is the Eolo. It charges its batteries with an innovative and efficient technology that employs wind energy. It gets its name from the fact that it is the world’s first ‘eolic’ car, which means it is powered entirely by wind.
Minuto de Dios Industrial Corporation The first prototype of an electric automobile that recharges with wind energy was constructed by Javier Roldn, the system’s creator, and project Eolo designers. The device works on the simple premise of a spinning wind turbine charging batteries, which then power the wheels.
On the front of Eolo are massive horizontal propellers or wind turbines that spin quickly as the car moves, sucking in wind and converting it into electricity to charge the electric car’s batteries.
The turbines are said to contribute up to 10% to Eolo’s total range, and it can be charged overnight using a conventional plug connection. According to the project’s creators, the car has a range of 100 kilometers and a top speed of 100 kilometers per hour.
In Greek mythology, Eolo, or Aeolus in English, was the keeper of the winds, and his name was used to name Roldn’s electric car with horizontal propellers.
While the technology is rudimentary in its current form and may take a long time to mature into a viable contender, it is an important step forward in the development of electric vehicles.
Is it possible to mount a wind turbine on a car?
The generator can be switched to a wind turbine while the car is moving at a constant speed on the road, reducing fuel usage by around 15%. When the car speed exceeds 50 kilometers per hour, the charge type can be adjusted to wind turbine system, with the higher the speed, the higher the efficiency.
What is the time it takes for a wind turbine to charge a battery?
Using Chargers from Wind Turbines Using a power outlet to fully charge the HYmini battery takes roughly 4 hours. The built-in USB port on the battery allows you to charge your phone, MP3 player, or digital camera (or an adapter connected to the USB port).
How do you charge your phone if you don’t have a charger?
All of these solutions require either a charging cable or a wireless charging pad that is compatible with your iPhone or Android device.
- Charge your phone with a USB port.
- Using a Battery Pack to Charge Your Phone
- Charge your phone using a hand crank charger in an emergency.
- Use a solar-powered charger that is environmentally friendly.
What is a phone charger’s voltage?
All chargers convert your line voltage, which is commonly 120 or 220 volts, to 5 volts. It is this 5-volt side that is subsequently used to charge your gadget. Not only is 5 volts the same on all chargers, but it’s also the USB standard. USB cords deliver 5 volts of power at all times.
