ENLIL vertical axis wind turbine
Most of the traffic will be powered by the supposedly dreaded fossil fuels, but never mind. Natural wind can also play a part. It’s the impression of trendy modernity and conformity to prevalent climate theories that counts, presumably, as the amount of electricity produced will be limited, to say the least.

Istanbul has installed wind turbines that generate electricity using the air turbulence generated by traffic, reports The Independent.
ENLIL is a vertical turbine developed by Istanbul Technical University and tech firm Devecitech have been placed on roadsides in Turkey’s largest city to harness the wind generated by passing vehicles, and to soak up solar energy at the same time.
ENLIL also uses its built-in sensors to keep track of temperature, humidity, carbon footprint, and earthquake activity to gather information for city authorities.
Thanks to its relatively small size, the device can also be installed in places unsuitable for traditional turbines, such as next to paths and on the roofs of high-rise buildings.
The project was developed by entrepreneur Kerem Deveci, who had a brainwave while travelling on the city’s Metrobüs network.

“Kerem Deveci, who had a brainwave…..” E I E I O oh boy!
Is this a good replacement for rooftop solar?
Vertical axis turbines are not noted for their efficiency but at least this design gets a push on both sides from the traffic, unless there is a strong wind counter-acting the air flow. It is unlikely that the electricity generated would ever be enough to repay the cost.
To get better efficiency from these it may be necessary to redesign trucks and busses to be ‘less streamlined’ to push more air sideways. I am sure there’s a (subsidised) research project in that.
What about the venturi vacuum effect after passing?
Sorry to hear this. I thought Turks were smarter.
More of a publicity stunt this. Including the name Enlil, ancient god of wind.
But. If in a road tunnel the walls moved along with the traffic, thus reducing the flow resistance while converting that friction to electricity instead of heat. Nearer to ‘open channel flow’, plus a reduction in energy spent by the vehicle engine to push through. ?
Like putting fat lampposts in the middle of the road. What could possibly go wrong?

Turks rank climate change as ‘a significant issue’ of country

Maybe, but blaming human activities isn’t going to work.
What happened to engineering? There’s no way the cost of these will ever be recouped either in energy terms or financial terms.
The energy for this has to come from somewhere. In this case it comes from the air which is dragged along by the bus, and ultimately from the bus engines.
This, of course, makes the bus fractionally less efficient as it passes each turbine. Total efficiency, of course, is poor – it would be more efficient to run these pillars with their own motor. Most energy would be saved, of course, by better streamlining of the buses..
The solar panel on top is to charge a battery to spin the blade when nudged by a passing bus.
Performance art.
I don’t see any wires to/from. If it ‘generates electricity,’ it is only to charge its battery. From the article, it appears to be a weather station. Period. Powered by wind and solar.
I don’t think the Independent’s writer asked many questions.
Looks like that wind turbine has a photocell on top. Isn’t that cute?
These, no doubt grant hungry, thing’s couldn’t punch a hole in a wet newspaper.
Passing Wind seems appropriately ironic.
Oily grime will quickly collect on the solar panels and no one will clean them.
Near where I live this happened right away with trendy parking pay-kiosks. These, I am sure, get their needed power from the grid, invisibly, up from the sidewalk. Yet they have the panel on top, with encrusted bird droppings as well as the grime from the traffic.
