They are Canada geese, not Canadian. Look it up. Named after a guy named Canada.
Notsomuch. They were named by Carl Linnaeus (below left - ignore the trollop on the right), who has a much more distinguished taxonomical pedigree. He also knew who Branta canadensis belong to. On second thoughts, those things **** everywhere. You can keep 'em!
Young Jim, as a lad
He looked for adventure
Calamity, danger, whatever was free
So when he turned ten, he packed his belongings
And he left home to find his destiny
Jim just a boy, who's
Head full of legends
Of dungeons and dragons
And pirates and stuff
So that summer he snuck on a schooner
To harpoon tuna
And get real buff
The Captain he said
There's danger ahead
We need some brave men
To sail and then
We'll find us those pirates
Stop them with violence,
To make the ocean safe
Once again."
Ahem Now, the pirates the brave captain was looking for, were the fierce midget
pirates of Willygoat. The deadliest in the seven seas, and although they were
wee men, they had big swords and were known for gutting many and leaving few
alive the captain knew they were headed towards the sandwich islands to pillage
the giant ham farm. The captain knew what he must do, and this is his story.
(chorus)
Cleaning up the oceans
Captain Hampton and his crew
Trouble in the seven seas
He'll know what to do
Captain, he hates rubbish
To him pirates are just soot
Scallywags and scurvy dogs
Are crushed under his foot.
Captain Hampton, Captain Hampton
Ahoy, Ahoy
Pillaging the Pillagers
Triumphantly he'll sail away
Now, seven weeks into the trip
And Jim was sick to death
Of being sick
Some kind of action he wanted
As he searched the seas
For everyday was the same old... stuff
The night he felt like jumping ship
But then he heard a crash
Hit the starboard side of the ship
And bumped him out of his bunk
Onto his bottom
Our heroes drew their swords
As the midgets swarmed aboard
The pirates surprise attack
The tiny buccaneers
Caught us by surprise
As we tried to battle back.
It was horrible, they were everywhere, and unlike normal midgets who are
usually bright and clever and fun to be around, these midget pirates with their
beady little eyes, and sharp teeth bore down on us like fierce sharks, in a
feeding frenzy of blood, slashing at us with their swords gutting our bellies,
poking our bums clipping our knees. We knew not what to do, for the captain
was nowhere to be found. WHERE WAS THE CAPTAIN. WHERE WAS THE CAPTAIN. WHERE
WAS THE CAPTAIN.
We don't often think about the fact that missiles, which otherwise seem special and other-worldly, are just products which get manufactured on an assembly line.
Can I suggest the cool wire that shrinks when it is hot again?
Matt, I looked into Nitinol wire.
You are absolutely right, it is a very cool way to actuate heat extraction systems. As a matter of fact, certain Corvettes have a pair of Nitinol wire actuated flaps in the rear hatch to evacuate hot air in order to facilitate easier hatch closure.
Having said that, it has several drawbacks in my case:
Cost - The damn thing costs about 45 Euros a meter, and I need quite a bit of it since no one can guarantee 6% contraction. I need 58 mm of movement.
Routing - Since the wire will be long, I need to route it back and forth over the hot areas with pulleys. Said pulleys will have to metal, and I'm pretty sure contact points will play a role in how the wire heats and cools. Also extensive surgery, fiddling with pulleys and finding proper mounting points.
Possible buzz / weird noises with all that wire looped around on the bottom side of the hood.
Cost - again - 1 Euro used to be around 2 - 2.50 Lira, these days it jumped up to almost 8. Eight. Damn.
Lack of override - there may be times when opening the louvers would be undesirable, or, I may want to close them in a downpour while sitting in traffic. An override could be incorporated, but would be pretty complex.
Difficult / time consuming testing - test cycles would be pretty cumbersome and lengthy, even with a heat gun.
On the positive side, I learned something new, and it's all thanks to you.
So, props!

make a thread for this project... I'm interested in it a lot. I think it'll be really cool (ha!) and would love more details on it...
