Minnesota’s frozen turbines raise new doubts about wind power

Minnesota’s frozen turbines raise new doubts about wind power:

In Minnesota, the wind is blowing but turbines aren’t turning. The machines, bought used from California and installed last fall, are completely frozen in place. Even on the windiest days, the blades sit at a standstill, producing no power. Why should anyone care? The problem highlights some of the less intuitive challenges associated with wind power — long considered to be the most feasible and cost effective source of renewable energy.

The likely culprit in Minnesota: frozen hydraulic fluid, unfit for the state’s brutally cold winters. As the temperature continues to drop, these fluids have started to thicken, turning into jelly. This is a big problem, considering how much the Midwest has spent on trying to become the U.S.’s wind power corridor. Wind power is already intermittent — the wind isn’t blowing at gale speeds all the time. But being knocked out of commission for an entire season? That could be a deal breaker.

Helikopter-strålen är nya vapnet mot isen:

En het vattenstråle smälter snabbt bort is från rotorblad. Den nya metoden är en av flera innovationer som ska säkra elproduktionen i vintriga vindkraftsparker.

Nedisade rotorblad är ett gissel för vindkraftsägare i kallt klimat. Alpine Helicopter i Boden har utvecklat ett nytt sätt att snabbt få i gång produktionen när isen tvingar snurror att stanna: en helikopter som sprutar varmvatten.

– Det tar oss ungefär 1,5 timme att behandla ett kraftigt nedisat vindkraftverk, säger vd Mats Widgren.

A Bedtime Story (Or Explaining Our Money System To A 14-Month Old)

A Bedtime Story (Or Explaining Our Money System To A 14-Month Old):

Authored by Bill Bonner via InternationalMan.com,

We are explaining our money system to our grandson, James, now 14 months old…

His mother tries to get him to go to bed at 9 p.m. But the little boy’s internal clock is still on Baltimore time; it tells him it is much too early to go to sleep.


Bill’s living room transformed into a makeshift nursery

Grandpa takes over, drawing out the monetary system like a general spreading a map on a field table. “Here is the enemy,” he says gravely. “They have us completely surrounded. We’re doomed.”

James grumbles. He squirms. He has a sunny, optimistic temperament. But we think our explanations are sinking in.
