This is a 1 day course showing:
1. How to size a wind turbine for your home, farm or
2. How different types of windmills and wind turbines
work, their efficiency and costings.
3. Location of a wind turbine, including wind speed data,
hills, valleys, buildings, trees and turbulence.
4. We look at and explain a full installation here on the
farm and how much energy is produced, how its installed and connected
up, cable sizing, amperage, controllers, safety, inverters and dump
5. We show how the homebuilt wind
turbine is extremely efficient, easy to maintain, storm proof, well
balanced, and visit the working turbine plus see all the parts taken
apart, with plenty to examine and test their outputs.
6. We show how different masts are constructed including,
mono pole, lattice tower and guy wires, and how they compare for price.
7. Blade profile carving and protection, steel
fabrication and alternator sizing.
This machine is highly efficient and the only successful home built
turbine for these large size machines.
We concentrate on a 2.4m turbine on the course and show how this size
machine can be connected into your home for free electricity or hot water. ( This
turbine can be connected easily and gives constant hot water from the
The different-sized machines, up to 5.2m rotor, are all similar to make,
and we have detailed drawings for all machines.
The Wind Turbine’s efficiency is due to:
No Gear Box - speed of propellers is the generator
No Friction - Most wind turbines, including this
design, use permanent magnets. This means brushes are not needed as
magnets travel close to the stator, without touching, so there is no
power lost, due to friction.
Tried and Tested: This design is being built
throughout the world for the past 30 years, due to its simplicity and
Grid vs off grid
Sizing a turbines
Alternator design and building
Assembly and balancing
It is the simplicity of its design, with overspeed
protection & storm resistance, which makes it a very terrific
option for producing your own power.
The turbine can be installed to
batteries, to the grid, or to heat water, and we cover all these aspects
on the course.
