I always feel sorry for the donkeys on the beach. They’re probably all well looked-after, but as animals go, they just have a permanent aura of “oh well, here we go again”.

Strandbeest [link] are amazing, whimsical wind-powered walking sculptures.

This one is modified to have a passenger seat, for an entertaining barely-controlled beach-based ride.

Large beach and wind required.

       Fun and slightly dangerous [+]

       // slightly //   

       Oh. How dull ...   

       Can there not be a "hideously dangerous" option ?   

       Powered by air movement - so this is a wind-up, right ?

       What the hell donkeys on what the hell beach? I've lived on the beach, lived by the beach, lived above it, and beside it, and not once have I seen a donkey. (I'd say "or an ass", but that would be a big fat lie.)
blissmiss, Oct 08 2019
  

       It seems to be a uniquely British entertainment. <link>
8th of 7, Oct 09 2019
  

       //Makes me wonder why it hasn't been done.//   

       Sorta been done. Let me see if I can find it again. No guarantees, it's way harder to find stuff quickly than it used to be.   

       <few seconds later>   

       Can't find the first one I saw and this one is pedal powered but if you can figure out how to tack into a wind you're good to go. [link]   

       Wow, 8th, I had no idea. Still not sure why, but I guess it's ok. I've ridden horses on the beach so what's an ass or two? (perinax, I hate to admit it but I find that photo of the camels really beautiful. I mean, REALLY beautiful. Is this wrong, I wonder?)
blissmiss, Oct 10 2019
  

       Yes, it is wrong.   

       It is an idealized image of camels, that entirely fails to convey the full range of vile unpleasantness that camels perpetrate merely by existing.   

       To begin with, there's the Smell. Yes, the capital letter is deserved; the Smell of a camel is absolutely unmistakeable, right up to the point where the olfactory nerves shrivel and cease to function, which is about the same point that the choking and projectile vomiting starts. Then there's the noise (incredibly loud and discordant), the mess (you don't want to know about a camel's eliminatory habits), and the temperament (bad-tempered, antisocial, vicious).   

       Sitting on a camel is an exceedingly unpleasant experience. Sitting on a moving camel is worse.   

       The only redeeming feature of camels is that apparently they can be quite palatable if cooked correctly. We have no direct information in this area.
8th of 7, Oct 10 2019
  

       I like them from a distance and the shadows they throw are beautiful. End of story. I don't like to tally up what is bad about any animal. I much prefer instead to see the good. Just like people. It's my nature, I guess.
blissmiss, Oct 11 2019
  

       // I much prefer instead to see the good. //   

       But what if there isn't any "good" to see ?

       No! [bliss] don't tell him that, this is [8th] you're talking to, quick delete it or he'.. Uh, OK never mind, too late.   

       So what did you find in there [8th]?   

       Anyone for camel kebab?
Skewed, Oct 11 2019
  

       // what did you find in there [8th]? //   

       Quite a lot. There's a bloke in a silvery trouser suit and a funny hairdo singing rock and roll; a racehorse; a big, tall bloke who says his name's Lucan; a bunch of people in victorian clothes who claim they got off a ship called the Mary something; a squad of American pilots in WW2 era flying gear; and the usual crowd of Lizard People playing strip-poker to decide who gets to play Prince Phillip next month.   

       We'll send another report once we get in through the door.
8th of 7, Oct 11 2019
  

       Big camel, we''ll need more people to eat all these kebabs.
Skewed, Oct 11 2019
  

       I've eaten camel. Not a whole one, obviously (although it might not be obvious; I suppose someone stranded on a desert island with only a camel might, over the course of some weeks or months, eat all of it, with the possible exception of the bones and teeth). I believe it was a steak from the hind quarters of the animal, cooked on a barbecue until it was seared and caramelized on the outside but still pink in the middle. I have to say that it was really jolly tasty - robust and yet tender, with a slightly bloody tang to it. It benefitted immensely from having some rock salt rubbed into it before it was cooked, and I wouldn't hesitate to have it again.

       I've eaten horse, kangaroo & something that came out of a tin claiming to be aligator (very fatty & vaguely like pork as I remember, not entirely convinced it wasn't), I wouldn't turn my nose up at camel, or practically anything else that wasn't a personal friend (family pet), or human.

       Strandbeest jousting would be quite an event, though it would require the use of some kind of power supply instead of a one directional wind.
xenzag, Oct 12 2019
  

       My understanding is that Strandebeest can be configured to walk into, with or across the wind.
MaxwellBuchanan, Oct 12 2019
  

       Well we're not delving into the mechanics of strandbeeste until after we've found our way out of this bloody camel ...   

       I suppose if we just beam back to our Cube you'll accuse us if cheating ... ? Don't bother to answer ...   

       <Types/> GO SOUTH   

       Hey ... we can hear music. It's coming from over there ... behind the red velvet curtains ...
8th of 7, Oct 12 2019
  

       //after we've found our way out of this bloody camel// OK, it's worth knowing a few things.
(a) there are only three ways out of a camel, or four if it's a female
(b) one of them is very, very unpleasant
(c) the others are worse
(d) points (b) and (c) apply equally from your and the camel's perspective
(e) when travelling by rail in the Netherlands, if it's a double-decker carriage, the top deck is first class (not of immediate help, but worth bearing in mind for the future).
MaxwellBuchanan, Oct 12 2019
  

       I was assuming that [8th] would make another way by channeling his inner xenomorph (an extraordinarily dangerous process if recursion sets in).

       ... sorry, sorry, we were just getting some popcorn ... yes, his habit of "keeping something for later " combined with his interests in necrophilia and zoophilia have resulted in some particularly vile and disturbing "finds" - and his deteriorating short- and medium-term memory from his prolonged substance abuse has just made things worse ... shhhh the lights are dimming, must be about to start ...
8th of 7, Oct 13 2019
  

       //configured to walk into, with or across the wind//   

       I’ve been pondering that. With and cross-wind, fine.   

       But Into wind...   

       From sailing, (as an analogy), it shouldn’t be possible. But then, I can imagine a thing with a big wind turbine that spins a lot, being able to crawl slowly up-wind. But that doesn’t make sense.   

       You could have a machine with a wind turbine that anchored itself securely while the wind blew, and accumulated energy in a battery. And when the wind stopped, used electric traction to crawl “up wind”   

       The net force on the machine would be in one direction, but it would move (net movement) in the other direction- hence negative work done.   

       I think it’s breaking one of the laws of thermodynamics.
Frankx, Oct 15 2019
  

       Surely you could cut out the electric middleman; just gear your wind turbine to a sort of drive shaft which turns an axle whose wheels dig a little into the sand, like the paddle wheels of a Missisippi gambler. The angle to the wind of the blades of the turbine will then play a role loosely analogous to that played by the angle of the keel in the water when a sailing ship is tacking, but with more moving parts.
pertinax, Oct 16 2019
  

       Yes, true [Pertinax] that sounds rather elegant - but I'm playing with ideas to see what's broken here.   

       I think it shouldn't be possible to have a wind-powered machine that travels up-wind. But we've quickly come up with a couple of ideas that look like they do exactly that.   

       It looks to me like these break some law of conservation. But I'm not sure exactly what.   

       If work done = force x distance moved, and our wind-powered thingamyjig is moving into the wind (against the force) then it's doing work against the wind. And it looks like it can do that indefinitely.   

       I don't like that. It's like a gravity-powered device being able to climb a ladder indefinitely - hints of perpetual motion and all.   

       And yet - when you're sailing, you can tack upwind. You can't point directly into wind, but over two tacks, your net distance moved is upwind, against the net force.
Frankx, Oct 16 2019
  

       It's only perpetual until the wind stops.
pertinax, Oct 16 2019
  

       //I think it shouldn't be possible to have a wind-powered machine that travels up-wind.//   

       You can certainly have a wind-powered machine that travels upwind. As a simple example, consider a wind turbine driving a set of very grippy wheels (or tracks). Such a machine can travel into the wind as long as the gearing is right (ie, it takes many revolutions of the turbine to drive the machine a small distance into the wind).
MaxwellBuchanan, Oct 16 2019
  

       There seems to be an echo in here.
pertinax, Oct 16 2019
  

       Ah - yes, you beat me to it.
MaxwellBuchanan, Oct 16 2019
  

       //certainly have//... I agree, it looks really simple to build one. But I’m struggling to see how the physics works- particularly in terms of work done.
Frankx, Oct 16 2019
  

       Viewed as a problem in statics, it's not obvious. The force exerted on a flat surface by the wind must be opposed by the supporting structure.   

       But in that case, no work us done; nothing moves.   

       Instead,the problem is dynamic; because the wind is moving.   

       A windmill, in opposing the force of the wind, extracts (say) 1000W from that wind - not unreasonable, a 1 kW windmill isn't that big.   

       You therefore have 1000W to do with as you wish. You can raise a mass against gravity, creating potential energy. You can convert it to electricity and light a lamp (dissipating it as heat) or charge a battery. You can compress a gas, giving some potential energy, and some thermal losses. Or you can use it as direct mechanical power.   

       Whatever you do with it, that 1kW is decoupled from the source (the windmill ) and with suitable gearing can be used to move the whole assembly in any direction you choose, even dead upwind.
8th of 7, Oct 16 2019
  

       Thanks 8th. That helps.   

       Reminds me of a joke... punchline was   

       “Well, that’s all very well in practice, but how does it work in theory?”
Frankx, Oct 16 2019
  

       // That helps. //   

       It does ? Sorry, quite unintentional - it's being stuck inside this camel ...   

       Oh, the curtains are opening ... lights coming up ...   

       Now there are two blokes with moustaches dressed like Egyptians and a rather attractive lady dressed as a belly dancer coming onstage ...   

       Just a sec ... <Activates audio stream redirection/>   

       " ...Sand bags, wind bags, camels with a hump,
Fat girls, thin girls, some a little plump,
Slave girls sold here, fifty bob a lump,
In the old bazaar in Cairo.

Brandy, shandy, beer without a froth,
Braces, laces, a candle for the moth.
Bet you'd look a smasher in an old loin cloth,
In the old bazaar in Cairo.

You can buy most anything,
Thin bulls, fat cows, a little bit of string,
You can purchase anything you wish,
A clock, a dish and something for your Auntie Nellie,
  

       Harem, scarem, what d'ya think of that,
Bare knees, striptease, dancing on the mat,
Umpa! Umpa! That's enough of that,
In the old bazaar in Cairo.
  

      
Rice pud, very good, what's it all about,
Made it in a kettle and they couldn't get it out,
Everybody took a turn to suck it through the spout,
In the old bazaar in Cairo.

  

       Mamadan, Ramadan, everything in style,
Genuine, beduine carpet with a pile,
Funny little odds and ends floating down the Nile,
From the old bazaar in Cairo.

You can buy most anything, Sheeps eyes, sand pies, a watch without a spring,
You can buy a pomegranate too, A water-bag, a little bit of hokey pokey,
  

       Yashmaks, pontefracts, what a strange affair,
Dark girls, fair girls, some with ginger hair,
The rest of it is funny but the censor cut it there,
In the old bazaar in Cairo."
