What is AirEnergy3D?
- AirEnergy3D is a 3d printed wind turbine that you can setup on your balcony, roof or take it camping
- It can generate up to 300W of electrical power
- It's small, it's durable, it's customizable and it' very cheap compared to existing wind based solutions
- ...and the cool thing is you can fit it in a backpack, move and assemble anywhere without using powertools!
You can use the power you produce as you go, store it in a battery or better yet 'charge' your home so the whole family can use it!
In a nutshell AirEnergy3D is clean and renewable energy that saves you money and saves the enviroment!
For every 2,500£ pledged we will send one fully working AirEnergy3D with preprinted propellers to African villages where energy is most needed. We will work with several organisations to find those places so helping the project means helping those in need!
The goal of this campaign is to gather funds to finish the design and prepare production of preassembled kits, that are easy to setup for everyone around the world.
We want to influence people, how they think about electricity and the enviroment. If we really want a change to happen, we know we can't keep the solutions to ourselves so we decided to make AirEnergy3D open source.
What does it mean?
It means once we develop AirEnergy3D we will upload all technical data for everyone to use free of charge. All the components are fully catalogued, together with assembly instructions.
Anyone who is a DIY fan will be able to modify AirEnergy3D to fit his or hers needs! Support AirEnergy3D NOW!
Backer support starts at 6£!
How does it work?
AirEnergy3D is 3d printable, but not in it's entirety. We provide a Basic kit with parts that cannot be printed on a desktop 3d printer and provide you with downloadable and editable 3d models of each required part, together with asembly instructions.
It's basically like putting a small lego model together. The design will let the whole kit and propellers will fit into a special backpack for comfortable mobility.
Thanks to 3d printing Technology at a very low Cost you can replace almost every part yourself, if neccesary.
Once you have AirEnergy3D setup you can plug-in directly using a USB extension cord and charge your smartphone and power your laptop at the same time.
You can also use AirEnergy3D to charge a battery or plug it directly to your wall socket so that your entire household can use the generated power and save money!
AirEnergy3D Basic Kit is planned to cost around 350$! That`s extremely cheap for a renewable energy source you can even take camping if you want to!
The cost of 3D prints dropping each day, so the final product is still a couple times cheaper than your usual, heavyweight, stationary wind turbines.

Who are we?
We are Omni3d. A 3d printer manufacturer from western Poland.
We know 3d printing is more than just a cool gadget for your desktop. We want to show how it can actually improve our lives TODAY. AirEnergy3D is our way of showing that a 3d printer can actually print something of greater value than the printer itself.
We live the 3d revolution and we realised, that in the era of epic social movements, such as user generated mass entertainment, music, film and so on, we can actually show people how to generate free electricity at home! We knew we had to do it! But ... we can't do it without your help!

Why are we doing this?
Why do we want to make AirEnergy3D a reality?
Because it’s cheap energy, because it makes energy available in places where it wasn`t available before, it`s green, it saves money and because … with your help - we can!
Support our kickstarter campaign!
The work so far
Right now we have built a proof of concept. We went through various wings and shaft designs and eliminated most of the faults and imperfections. We managed to generate enough electricity to light a lightbulb just to see if it works, and it does! We have all the plans and we want to work on them fast in order to generate 300W of power for a single unit. We need your support for that!
So what`s the plan?
We want to develop the basic kit so that it`s super easy to transport and setup. For those using our open source database we want to design it so that it`s possible to assemble the kit with things you can buy at your local store.
Our campaign goal is set to enable our design and developer teams to focus their work on :
- Perfecting a scalable model
- Perfecting a foldable design
- Creating an efficient electrical circuit
- Setting up production
- Kickstarter backers delivery
We are working on a mounting system which will allow AirEnergy3D to be installed on various surfaces, weatherproof and safe. After we have a 100% functional master model we will setup production and shipping of the base kits, and 3d prints in case anyone needs them. We have a couple of aces up our sleeve in case the funding is successful and we can think about stretching the goal.
We want to be able to launch production of fully functional AE3D after 3 months from funding the project. Our backers will have their models delivered first order ofcourse!
Back this project now and inspire others to save the enviroment and their wallets!
Risks and challenges
We know we can do this, but there is always risk that something turns up more difficult than expected.
One obstacle we are thinking of is a method to firmly mount the AE3D on various surfaces. We are looking for a 'fits all' solution but we know, that this may not be possible.
Therefore we are considering preparing instructions for users to resolve their individual needs. Providing each order with a set of information on how you can manage on difficult material.
- up to 25A with 12V output
- 220V (300 WATT) – 1.4 A - post attached inverter
- 120V (300WATT) 2.8A - post attached inverter
- the design is compatible with any 12 VRLA battery
- regulated height 1,2 - 2.5m (3.93 - 6.56 feet)
- diameter 125 cm (4.1 feet)
- 25kg (55 pounds) – whole thing not counting the stand
- can be used with any wall satellite dish mount
- Yes, but not directly. It’s doable using an additional inverter syncing with AC curve. Just as with any other source of renewable energy.
- compatible with DC home systems
Short answer is 10 m/s
Long answer is:
ρ - air density ρ=1.2 kg/m3
v – wind speed m/s
F - cross sectional area (of the wind stream hitting the turbine) m2
k – power factor (efficiency)
Max k for wind turbines is between 0.3 and 0.4, F cross sectional area is equal to rectangle area through which the wind stream goes through to reach our turbine, for our turbine it is:
Substituting all data for wind speed of 10 m/s and power factor of 0.3 (worst option)
With 0.4 power factor and 10 m/s speed
- the printed blades are not subject to heavy loads
- we simulated applying a 100N force on the top of the whole 2.5m structure. The bend does not exceed 1.2mm
- we are currently researching and simulating applying loads.
- in case of exeeding max RPM our safety mechanism kicks in and slows down or even stops the turbine
Min wind speed is 3m/s, what is typical of this type of devices. The wind turbine reaches 300 WATT at 10m/s wind.
Metal elements (bearings, aluminium shaft, steel base, standard fitting), generator, electronics, inverter for 120 or 240V, cables, VRLA battery 18Ah
Central shaft is made of two pipes (rod 21.3mm (0.82 inch) in diameter) and an external rotating pipe 60 mm (2.36 inch) in diameter. Inner one is steel, the external one is aluminium.
Straight DC 12 V directly from battery. Later it is converted using the attached inverter into 120 or 220V. USB socket for 12V and typical power outlets for 120V and 220V.
There are two electronic modules. The first one is responsible for optimal use of wind energy and charging the battery. It is also responsible for not letting the battery overcharge and slowing down the wind turbine in strong wind. It also controls the load in order to reach the optimal speed and maximum power.
- we know how much energy is delivered to the battery (WATT, V, A)
- we know the energy output (WATT, V, A)
- we know when the battery is fully charged
- we know rotations per minute of the turbine
- we estimate the wind speed (m/s)
- we do not let the battery get overcharged
protection from the max rpm of the turbine
- we can connect the turbine using ethernet cable and monitor its status and operation via web browser or phone app.
At what height would the ideal installation be so as to capture 10m/s winds? (Usually called "Hub height" for traditional wind turbines)
The hub height depends on the particular area, where the wind turbine is installed. In the windy places, such as seashores or mountains, elevation of 6 ft is sufficient to capture 10 m/s. In the places, where the lay of the land is especially unfavorable, the demanded height may even several times bigger.
