Someone just posted a photo stating that a wind turbine in Norway had its blades pained black and it reduced bird deaths by 70%. It sort of beggars the question why we have things that kill birds (and bats and especially Avian predators) in such high numbers in the first place but progress is progress as we are only killing 30% of those birds now!! Isn't 30% still too high and as I always say 30% of what? It's hundreds and hundreds, the blades look innocuous enough but the speed they actually travel is far higher than you'd think. So I asked Gemini. It gave this response:
"For large, utility-scale turbines, the tips of the blades can reach speeds of 180 to 200 mph (290 to 320 km/h).
Some of the largest offshore turbines, designed for very high wind speeds, can reach speeds of over 250 mph (400 km/h).
For smaller, domestic wind turbines, the tips travel at a much lower speed, typically around 75 to 100 mph (120 to 160 km/h).
To put that into perspective, the tip of a large wind turbine blade can move faster than many high-speed trains."
Whilst I am on the subject I find the whole language of journalists problematic. So two words they use are "Unprecedented" (nothing to do with Donald Trump) and "Exponential"
Again, trusty AI states:
Unprecedented means something that has never happened or existed before.
The word literally breaks down to "un-" (not) and "precedent" (a previous example or model), so it describes a situation, event, or action that is entirely new.
The term is often used to describe things that are shocking, significant, or on a scale never seen before, such as:
Unprecedented levels of rainfall
An unprecedented global health crisis
The company saw unprecedented growth in sales.
So now just think about that in terms of the first example because that is where I read it. Yet, there was nothing unprecedented about it at all. It had happened in the same area some fifty years prior and some seventy odd years before it as well so it was perhaps once in a generation event but not unprecedented at all.
Then there is this:
Exponential describes a process of growth where the rate of increase is proportional to the current amount. In simple terms, it means something is increasing at a rapidly accelerating pace. Think of it this way:
Linear Growth: This is a steady, straight-line increase. If you earn an extra $10 a day, that's linear. You're always adding the same amount.
Exponential Growth: This is a doubling or tripling effect. If something doubles every day, it starts small but quickly becomes massive.
A classic example is a single grain of rice on the first square of a chessboard, with the number of grains doubling on each successive square. You start with 1, then 2, 4, 8, 16, and so on. By the 64th square, the number of grains is larger than what the world could ever produce.
So, when someone says they've seen exponential growth, it means the numbers aren't just getting bigger; the rate at which they're getting bigger is also increasing dramatically.
So now go and look at the news and where they describe something as exponential they generally mean fast not linear and yet describing inflation as exponential when it has gone up a lot or population increases isn't really accurate - perhaps for Locusts breeding out of control they'd probably be exponential but it is a lazy term and is used out of context.
I think that is it really, a lazy catch all phrase overused and abused as it doesn't mean what they use it for.
Watch out for those weasel words and those strange benefit claims which now reduce deaths by 70% when really we shouldn't be advocating machinery that causes any deaths!
