Vindasamur morgunn - A windy morning

Skjˇtt skipast ve­ur Ý lofti.

═ morgun rei­ yfir miki­ hvassvi­ri me­ regnhry­jum og um tÝma var vindstyrkur um og yfir 20 m/sek.

TŠkifŠri­ var nřtt og roki­ hljˇ­rita­.

Nota­ur var Zoom H-6 hljˇ­riti me­ X/Y-hljˇ­nema, sem var varinn me­ svampi og lo­hlÝf.

MŠlt er me­ gˇ­um heyrnartˇlum.

The weather changes rapidly in Iceland. This morrning it was quit windy with showers, about 20 m/sec. The opportunity was used to record the wind and the rain.

Recorder: Zoom H-6 with an X/Y microphone covered with a foamshield and a hairy windprotection.

Good headphones recommended.

ReykjavÝkurhlaup 2014 - Reykjavik Running 2014

Eindregi­ er mŠlt me­ a­ fˇlk hlusti ß me­fylgjandi tv÷ hljˇ­rit Ý heyrnartˇlum.

Laugardaginn 23. ßg˙st var hi­ ßrlega hlaup hß­ Ý ReykjavÝk. R˙mlega 1100 manns tˇku ■ßtt Ý mara■on og hßlfmara■on-hlaupinu og r˙mlega 8.000 Ý 10 km skemmtihlaupi. Ůetta hlaup hefur veri­ hljˇ­rita­ nokkrum sinnum frß ßrinu 1998.

fyrra sřni­ er frß ■vÝ kl. 09:05, en ■ß h÷f­u fyrstu hlaupararnir fari­ framhjß. Hßva­i frß bifrei­um var of mikill til ■ess a­ hljˇ­riti­ nyti sÝn.

Seinna hljˇ­riti­, 10 km hlaup, hˇfst rÚtt fyrir kl. 10:00 ■egar fyrstu hlaupararnir voru Ý nßnd. Taki­ eftir hvernig fˇlk skirr­ist ekki vi­ a­ trufla hlaupi­. BÝlum var eki­ ß mˇti ■vÝ, fˇlk lag­i lei­ sÝna gegn hlaupinu ß hjˇlum og gangandi o.s.frv. En hlaupani­urinn rennur framhjß eins ot vatnsfall.

Hljˇ­rita­ var me­ R°de NT-2A og NT-55 Ý MS-upsetningu. Hljˇ­ritinn eins og oft ß­ur Nagra Ares BB+

Hljˇ­nemarnir voru settir nor­an vi­ Tjarnarbˇl 14 vi­ Nesveg ß Seltjarnarnesi.

This recording is best enjoyed by using headphones.

The annual Reykjavik Run was held on August 23. More than 1100 people participated in Marathon and Half-Marathon and over 8.000 in 10 km running. The event was recorded as has been done since 1998.

The first sample started around 09:05 when the first runners had arrived. Due to the noise from cars the recording before is not worth listening.

The second sample started around 10:00 when the first runners were approaching. Pay attention to how people tried to disturb the runners by driving, biking and walking against the stream.

The runners pass by like a river of people.

Recorded in an MS-Setup with R°de Nt-2A and NT-55. The recorder is as most often Nagra Ares BB+.

Recorded infront of Tjarnarbˇl 14 at Nesvegur, Seltjarnarnes.

Raforkuvindmyllur - Wind Turbines

Hljˇ­i­ Ý einni vindmyllu er notalegt. En hver ver­a ßhrifin er 80 myllur ver­a settar upp? Ljˇsmynd: ElÝn ┴rnadˇttirNor­an vi­ B˙rfellsvirkjun eru tvŠr vindmyllur. Ůegar okkur bar a­ gar­i 26. ■essa mßna­ar var vindur um 5-10 m/sek og raforkuframlei­sla einungis um 75 kW. Nokkru nor­ar er ÷nnur vindmylla, sem ekki var opin, en ■ar sem enginn var vi­ hana var h˙n valin til hljˇ­ritunar.

Um ■a­ leyti sem hljˇ­ritun hˇfst jˇkst vindurinn nokku­. Ůa­ mß heyra ß hljˇ­ritinu hvernig hljˇ­i­ breytist me­ mismunandi vindstyrk.

Eindregi­ er mŠlt me­ gˇ­um heyrnartˇlum.


┴ sÝ­u landsvirkjunar segir m.a.:

Vindmyllurnar eru hvor um sig 900 kW og samanl÷g­ raforkuframlei­sla ■eirra er ߊetlu­ um 5,4 GWst ß ßri. Ůa­ myndi nŠgja til a­ sjß um 1.200 heimilum fyrir rafmagni til daglegra nota.

Loki­ var vi­ uppsetningu vindmyllanna Ý desember 2012 og ß nŠstu misserum safnast upplřsingar um ■a­ hvort m÷gulegt sÚ a­ breyta Ýslenska rokinu Ý ver­mŠta au­lind. Rannsˇknirnar sn˙ast ekki sÝst um rekstur vindmylla vi­ sÚrÝslenskar a­stŠ­ur, Ýsingu, skafrenning, ÷sku- og sandfok. Ef vel gengur er markmi­i­ a­ vindorkuframlei­sla ver­i Ý framtÝ­inni mikilvŠg vi­bˇt vi­ framlei­slu raforku me­ vatnsafli og jar­varma.

Vindmyllurnar tvŠr ß Hafinu eru framleiddar af ■řska fyrirtŠkinu Enercon, sem sÚrhŠfir sig Ý framlei­slu vindmylla til nota ß landi. Um 60% vindmylla Ý Ůřskalandi eru frß Enercon og um 7% vindmylla Ý heiminum.

Turninn er 55 metra hßr og hver spa­i 22 metrar ß lengd. Ůegar spa­arnir eru Ý efstu st÷­u er heildarhŠ­ myllunnar 77 metrar. Frekari upplřsingar eru ß

Will the wind finally do some good?

In December, Landsvirkjun erected two wind turbines, in an area known as Hafi­, within the construction area of B˙rfell Power Station, in the south of Iceland. The turbines have a total of 2 MW of installed power. The project is part of Landsvirkjunĺs research and development project on the advantageous of wind power in Iceland. There are a number of areas in Iceland that show great potential for the successful utilisation of wind energy.

The wind turbines each have a 900 kW capacity and together their generating capacity could be up to 5.4 GWh per year. The masts is 55 metres heigh and each spade measures 22 metres in length. When the spades are at their highest position the unit is 77 metres of height. Wind turbines developed for further energy production will in all likelihood be larger than the most powerful turbines presently operating in Iceland today, reaching 7.5MW.


When we were there on July 26 the wind was only 5-10 mYsec and the average power only about 75kW for each turbine. We went to the turbine further north as there were no tourists. There we captured the sound. It can be heard during the recording that the sound of the spades changes according to the wind.

Good headphones recommended.
