Wind Power: Power generation with invisible costs
How Wind Power works
Historically, wind power is older than writing or culture. It was used to power ships from ancient times, or mills for grinding food. Hammurabi’s Codex circa 1750 BC refers to mills doing mechanical work. Netherlands is famous for her Windmills which drained lowlands of water. Nowadays wind turbines may be off shore (very big) or, on shore.
What wind power generates (profit)
A wind turbine has a rating, but that is a maximum output for its’ power, which practically will not be achieved
A turbine cannot safely produce energy in wind speeds below 25 kph and above 88 kph
The local weather gives a rating (%) for effective use of a turbine, typically between 30 and 50% of output
Eg a 1.5 MW operating at 25% efficiency can produce 1500 x 0.25 x 365 x 24 = 3, 285, 000 kWH a year. This assumes 24 hour a day availability which does not happen.
2 million kWH in Victoria averages $560,000 at $0.28 per kWH per year

Jingle bell, jingle bell, jingle bell rock
Jingle bells swing and jingle bells ring
Snowin' and blowin' up bushels of fun
Now the jingle hop has begun
Jingle bell, jingle bell, jingle bell rock
Jingle bells chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell rock
Jingle bell, jingle bell, jingle bell rock
Jingle bell chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell
That's the jingle bell
That's the jingle...

The Good Shepherd Blues
(John’s Song – Ephesus, sometime around AD 95)
(Slow 12-bar blues in A minor – play it like an old man who’s seen too much but still got fire in his eyes)
Verse 1
I am the disciple that Jesus loved, they say

Beethoven’s Last Blues (John’s Gospel in D-minor)
🎹 Turn the lights down low.
Grab your oldest headphones, your darkest room, and the heaviest heart you’ve got.
Play “Beethoven’s Last Blues” once—at the volume you’re scared to use.
Let it crawl inside the silence you carry.
When the final low D fades into nothing, don’t move.
Stay there in the dark until you feel something rise up that has no sound.
That’s the Word becoming flesh in you.
That’s joy breaking through deafness.
Now pass it on.
Send it to the one who’s lost their music.
Tell them: the conversation hasn’t ended.
The Ninth is still coming.
And it’s coming for them.
Play it loud enough for the deaf to hear.
Because joy was made to outrun silence.
#BeethovensLastBlues #TheWordBecameFlesh
Woke up this mornin’, world gone black as coal,
Ears full of silence, Lord, it done swallowed my soul.
Fingers still dancin’ on keys that don’t speak no more,
Hammer and string keep lyin’, like a lover walkin’...
Stand with the Blue: Honor Nicola Cotton, Learn from Redfern
Imagine a young officer, full of promise, gunned down in broad daylight—her only "crime" was stepping up to protect her community. That's the heartbreaking reality of Nicola Cotton, the 24-year-old New Orleans policewoman murdered in 2008 while trying to arrest a suspect. Eight weeks pregnant, she was shot 15 times with her own service weapon by a man with a history of severe mental illness who had been prematurely released from care. Her death wasn't just a loss for Louisiana; it exposed raw cracks in our systems—mental health failures, under-resourced patrols, and the relentless dangers officers face in high-risk neighborhoods.
Now fast-forward to Sydney's Redfern riots of 2004, half a world away. A 17-year-old Indigenous teen, TJ Hickey, dies in a tragic bike accident during what police called a routine patrol—but his community saw it as yet another flashpoint in a cycle of distrust, poverty, and ...
