What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

There is a big marked for windmills, if they could be installed on the houses and inside the city limits.

If the windmill also produces more than 2 kwh, on average, we would cut 50% off the coal and oil, making the world a green and more Renewable place.

This Vertical Windmill fills those three criteria, on paper.

I found the part, that makes it generate more energy than the normal version.

When it work, it generates about 3 KWh at a wind of 5 m/s. That is enough energy for a single family household, if you also get a battery like the Tesla Powerwall. (That is not part of the plan.)

I made a small version for about 200 Dkr. From a kids bike, a bucket and my dad's help. That version needs to be on the side of a building. It works, but only when the wind is going along the side of the house.

I want to go bigger to make a Real life-size version.

This version will be place on top of a building. Getting wind from every directing and make more energy and show that my idea is workable in the real world.

Risks and challenges

I have done the patent search, so that part is covered.

The money goes into the parts.
1/3 to the construction. (Parts, labor, smaller electrics.)
1/3 to the generator..(a 10kw cost +3,000 $.)
The last will go to pay somebody to get it on their building, and let it run for 3 months.

The largest steps in the project.
1. Hire a machine shop to make the large version.
2. Make a working version. That will be the machine shops task.
3. Installing it on a house. (I have two sites, but maybe the machine shop, I have seen will be the optimal place.)
4. Get data from the Windmill. There are programs out there that does it for you...

I am talking with a company in my country, that has a lot of experience in making and selling private windmills, and they will help me to make the project work.
