nice email received:
From: Mike Allen
Subject: Re: A Wind Turbine Recipe Book
Date: 12 April 2013 10:53:18 BST
To: jytteI recieved the book yesterday and when it arrived I thought ‘this isn’t worth £12’.
But how wrong I was once I’d opened the envelope and settled down to read the contents with a cup of coffee. 3 hours later the coffee was stone cold and I was still reading the book.
Loads of info to be getting on with.
I’ll email Hugh when my terbine is up and running with some pics.
Thanks a lot.
Michael.

Things that don’t work – Mick Sagrillo on the popular idiocies of modern small wind.
This presentation by Mick Sagrillo is from 2009. It’s a good summary of what is wrong with rooftop wind and is backed up by actual production data. If you are enthusiastic about rooftop windpower then you ought to look at this presentation and then decide whether its such a great idea.

Damage to yaw head in Palestine
This is the tower after a 3 metre diameter (ten foot) turbine jumped off in reported 120 km/h winds in Palestine recently. The 1.5 inch inner pipe of the yaw bearing has clearly bent. COMET-ME will be using a larger pipe size for their yaw bearings in future. However this was the standard size that I specify in my Recipe Book.
Windspeed 120 km/h is only 33 m/s, which is not exceptional for us on Scoraig, but there could be other factors at work including turbulence. A high gyroscopic moment induced by a rapidly yawing rotor could be one. Anyway this is where this turbine failed and failures are useful lessons. That’s why I am sharing it on this blog.

Using the dump load to warm your toes
For many centuries in Central Asia, a traditional home heating method known as a ‘Sandali’ or ‘Korsi’ has provided families with a warm place to retreat into when the temperatures dropped below freezing. The homes and buildings in this region have limited insulation built within their construction and interior room temperatures can often approach the freezing conditions of the outside during prolonged spells of bad weather.

Recipe book translated into Swahili

by Anthony Karomba & Roland Valckenborg
“After giving the master class on Hugh Piggott wind turbines in Tanzania, it was recognized by the participants that not everybody is familiar with the English language. During the master class this was not a very big problem, because participants could help eachother translating English into Kiswahili, which is the national language of Tanzania. However, after the training all participants went back to their homes in very different parts of Tanzania. Although mobile phones are increasingly covering the country, it appears to be difficult for a lot of Tanzanian workshop artisans – also called ‘fundi’ – to help eachother on translating. Therefore it was decided to make an extra manual in the Kiswahili language. ”
