Posts Tagged ‘anemometers’

Following the success of my steampunk flag (and in particular the way the copper-coloured anemometer at the very top worked in the wind), I have been becoming a bit obsessed with these twirling devices!

I now find myself looking out for other anemometers, and in no time at all haveĀ spotted two such devices, both of very different designs and locations. . .

Firstly though, here is the original one from my flag – a four bladed version made from halved ping pong balls, some stout wire and an old electric motor for the freely-rotating spindle. Mine simply turns in the breeze for a bit of fun / decoration – the electric motor is not connected to anything, does not generate a charge or serve to run any instrumentation (although the next version might!?):

I was amazed to find this old photo of one of the earliest anemometers, and how incredibly similar the cups are to mine (even the slight distortion where the wire goes through the cups)

The second example is from the top of a boat mast (moored in Torquay harbour) – I am guessing it serves to measure the wind speed, whilst all the other doodads and doohickeys are for cunning things such as radar etc…

And finally, here is one that sits astride a lamppost on the business park where I work a few days…I’ve no clue why a business park needs to monitor wind speed – any ideas??

I am now obsessed with finding more such devices – if any of you out there spot any, please send me photos / details and I’ll post them up…
