Wind Generators and Wind Energy

What's the story with wind generators?

A wind generator is a wonderful thing, producing power 24 hours a day, no nasty pollution, easy to install, very little maintenance, and the joy of getting something for nothing, once your original investment is out of the way. 

There are some important considerations, of course:

• Wind generators like clean airflow, and they hate turbulence. They must be mounted where the air is smooth, not behind trees, not where buildings or natural features will cause rough air or wind flowing outside of the horizontal
• They do need some wind to get going (seems obvious, but is often overlooked). Typically around 7 knots (3.5m/s) to get started, and the power curve is very steep up to around 24 knots so, for example, a wind of 24 knots will produce around 12-15 times the power that you get with a 12 knot wind - double the wind giving 12 times the power
• They need to be safely and firmly installed, at a safe height, and where the blade noise isn't going to intrude (ie don't install it next to your meditation platform)
• Quality is everything - like most things if it is cheap, there's a good reason - so bargain basement wind generators are likley to bring a lot of heartache.

We've got a few things that we look for in a wind turbine, and our preferred model is the Superwind SW350.

Uncompromising Quality:

• High output, low noise
• 350 W at 25 knots (12,5 m/s)
• Maximum safety
• Pitch controlled rotor blades
• Cut in wind speed: 7 knots (3,5 m/s)
• Cut out wind speed: none
• Innovative design
• Compact dimensions
• Saltwater proof materials
• Neodymium magnets
• No vibration, no fuss
• Easy and quick to install
• Zero Maintenance Design
• Durable trouble free energy
• 3 years limited warranty
• Available World Wide
• Made in Germany

The Superwind 350 is a proven stand-alone wind generator
for autonomous and unattended operation. It is designed for a
wide range of rugged applications and can also easily be
integrated into wind & solar PV hybrid systems.

Made entirely from high grade materials - saltwater proof aluminium, stainless chromium steel, carbon fibre reinforced plastics, permanent neodymium magnets and a brushless motor.

Typical Applications:

• Sailing yachts
• Navigational aids
• Traffic information systems
• Measurement and transmitting systems
• Telecommunication
• Cottages
• Mountain lodges
• Rural electrification
