Penstock near Tonstad

Selected for Google Maps and Google Earth

A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydraulic turbines. This penstock leads to an Hydro-electric power plant.

Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy.

Norway lies 6th in the table of hydroelectric producers, and approximately 99% of the country's electricity is produced in this way.

As a matter of interest, the amount of rainfall/snowfall affects the price of electricity.

Thank you Per. ;-)

What is a nice lady like you doing up this damp dirty pipe line Amelia? You must drag that poor man of yours into some uncomfortable places :-(, but if he is anything like my good lady, he.ll find some way to be recompensed,L0L All the best, cheers scally. Like.

Amelia Royan on November 14, 2012

Thanks Scally, it's a photo that only an engineer could appreciate! It was dreich. My 'old man' wasn't with me - I was on a trip up to the mountains with my Norwegian guide, Per. I gave him 400 Kroner for petrol. LOL.

Cheers, Amelia

In addition to the joy I had of taking her for this tour. :-))

Amelia Royan on November 14, 2012


Yes the whole day was a joy. Now - aren't you supposed to be entertaining your svigemor?

PerO the Viking G- on November 14, 2012

As I said Amelia: Change in plans. Arriving tomorrow. :-))

Imagine whizzing down the railway track though ~~~ and the splat at the bottom ~~ perhaps that is why there is a red hand held aloft ~~~ xXx

Amelia Royan on November 14, 2012

In fact they are in the process of recreating a white knuckle ride based on this Penstock at Alton Towers dear Nick. One slides down inside the pipe in a toboggan rug, and just before one hits the generator, there is a 50 50 chance of sidestepping into a warm lagoon instead of being churned up by blades. The ride will be called Russian Roulette, and already there is a waiting list. ;-)

Nick Weall on November 14, 2012

Maybe it will really be a red knuckle ride as the blades do their grizzly work ~ so now the red hand warning sign has more significance perhaps ~~~

Hooray for gravity and hydro-energy so wonderful to make use of all that energy that is there just for grabs.

Regards, Erik

The Red hand must be on holiday!

Amelia Royan on November 16, 2012

Muito obrigado para o seu louvor Nivaldo e Maria. Estou muito contente que você visitou esta foto industrial.

Saudações da Noruega, Amelia

Amelia Royan on November 16, 2012

How right you are dear Erik. It rains a lot in the mountains of Norway, and of course that turns to snow in the winter. But when the sun is shining and the sky is blue it is a cross country skiers paradise. It looks so easy - I tried it - it isn't. ;-)

Groetjes, Amelia

Amelia Royan on November 16, 2012

Great minds think alike Bonnie Lad. I too thought straight aways about the Red Hand of Ulster. I had already seen it before on a mountain dam - it almost seemed like a welcome! ;-)

Rodel Teppisch fahrt im Rohr...dann lieber mit dem ZUG auf dem Gleis gegen die Wand-die Lok kann bremsen(;-))))

Sehr interessant für mich. Da ich in einer Firma in der Schweiz Arbeite die alle Komponenten für ein Wasserkraftwerk Herstellt könnten die Druckrohrleitung und die Turbinen von unserer Firma sein. Lk.

Amelia Royan on October 16, 2013

The component parts could certainly have come from your company in Switzerland Luke, It's interesting to know that the price of electricity in Norway varies according to the amount of rainfall.

Sorry to reply so late Pergyth. I think I'd prefer the locomotive ride with available brakes. One would come to a very unconfortable end point on a toboggan. ;-)

Greetings to you both, Amelia
