January - February I was in Germany. There have been plenty of onshore installations in 2016, probably as a short final. Because the now ruling bidding process forces the offerer into dumping. Only large financially strong companies can affort to offer very low prices at high risk. This accellerates the concentration process in the branch.

24-2-2017 happily back in China and eating with chopsticks.

March - April

Still two lectures and the milestone of the internal training program has been achieved. It will take some time until the fresh European know-how which I delivered will find its way through the documents into the machines.

The climate is not for European loungs, some sickness required some medicine.

Wind power is talked cheap, but there is no reason why it should become cheaper. We live in a phase of again rising oil prices and steadily rising raw material prices. Electro-mobility will raise the demand and prices for copper and magnets. This directly influences wind turbines. The larger series' made by fewer companies will slightly reduce manufacturing cost. But there is no technological breakthrough anywhere for a massive LCOE reduction and suddenly achieved grid parity. Having cooperated over the last 5 years with the highest-reputed experts and visited all relevant scientific fairs, I am sure not to have missed anything.


Wind-Europe loudly celebrates the dumping prices made by some energy giants. They are too big to fail and can be sure of government subsidies when the wind farms come into financial loss. The wrong signal is given to our politicians: "wind power does not need any subsidies". But it is dangerous to generalize such a statement. In most of all projects this is not the case. Any kind of corrective action in clean energy pricing is needed and justified. The wind energy industry should not be so stupid as to dig their own grave.

A business trip brought me to the Chinese district of Inner Mongolia.

Hundreds of kilometers of arid sandy land. Some sheep, a few cows and horses. The wind was so strong that it blew off my hat. The sun was so strong that I could hardly see without sunglasses.

The Mongolian horses do not confuse low-frequency modulation of high-frequency noise with infrasound. Also, they do not write emotion-based horror stories about wind power in the boulevard press.

HERE is the place for a really large-scale use of wind and solar power.

May - June With two more lectures now my educational program has ended. Over 1000 pages have been written in English language. It is now in the responsibility of others to make use of this high-level know-how, collected from 35 years of good and bad experience with hundreds of wind turbines. The biggest milestone is finished.

To my regret I have to state that the general know-how in the wind turbine industry has gone down. A well reputed British consultancy gave wrong rules to dimension the yaw system. Costly defects are the result, based on 3P cyclic hard-hits on the drives due to neglecting their play in the calculations. I have handled this problem already 1993.

And an also well-reputed company for pitch slewing ring bearings calculated FEM without the essential blade ovalisation effects. But these contribute a lot to premature damage of such a bearing. And they based their fatigue on ISO-281, which is irrelevant for the load state.

Evident loss of knowledge among companies and suppliers in the branch is being replaced by empty phrases such as "best practice" and "lean supply chain management" etc. This shall cover the simple fact that wind power has become a large-scale political poker-game of energy giants.

There has been a claim from one company against an other (I cannot tell details openly) in which I was involved by giving a neutral statement. To my surprise I noticed that a well-reputed company had given pure fantasy and lies as their statements.

A Danish "expert group" had vigorously confirmed these lies in a large official statement and proudly presented their "expert experience". Was it bribery or just the normal mud-slinging of the confused wind power branch?

In June I will be busy in Finland and Germany. Some bureaucratic affairs need my attention.

July - August

A 300 to portal crane, reaching out from the workshop hall over the sea, is ideal for the assembly and transport of offshore wind turbines. Quality assurance tasks now often bring me to Zhu Hai.

The ship engine company there assembled and tested an impressive 7-cylinder 2-stroke crosshead-based diesel engine. Scavenging happens with the help of an auxiliary exhaust valve. The engine has 10MW of rated power at 124 rpm, turbocharger and common-rail injection. It will power a container freight ship. It is very interesting to take a small look into other branches from time to time.

September - October http://www.sonnewindwaerme.de/windenergie/nordex-will-00-stellen-abbauen

After SENVION has massively laid off in the last half year, also NORDEX announces reduction of 400-500 work places. " ....as a reaction to reduced buyers interest and due to changes in the market conditions in Germany, Nordex has launched a program for cost reduction program of 45 mio E...." Here you see the reality of the much celebrated hoax of "wind energy becomes cheap". Some laymen still think about technical improvements. The reality: Wind power did not BECOME cheaper but was PRESSED down in price. That is the difference.

In Germany we had Federal Parlament elections. Big winners were the two fanatic anti-windpower parties FDP and AFD. The future of windpower will be now even more uncertain, no matter in which coalition the parties will form a new government.

Three Tai-Féngs caused a lot of damage in Zhu-Hai and Macao, also our workshop was damaged. In Zhong-Shan the storm was still moderate.

October went mostly for administrative matter in Europe.

November - December In December I moved back to Helsinki to support some European activities of Ming Yang. Work is running out slowly.
