it is with a heavy heart that I regret to inform you that the tech bros have invented sails
@stavvers itโ€™s a pity no one ever thought of this method before in the history of humanity. ๐Ÿฅบ
@ouinne @stavvers tbf that doesn't mean its a bad idea.
@stavvers always "inventing" something that exists.
@Wildheart_Baby @stavvers
Almost like they might've, I dunno, maybe dropped out of school or something, with declarations of "I don't need an education to get rich - I have my own great ideas!".
@stavvers Thus bypassing the restrictive, innovation-stifling regulations that such โ€œkitesโ€ be firmly attached to masts.
@stavvers But, but maybe it's a HyperSail or a GigaSail?
@stavvers Peter Thiel like "I think this is a fantastic idea, but I think it could be engineered a little more effectively by fixing the kites to the ship itself, a "mast", if you will. Here's a billion dollars"
@chrismerkel @stavvers Good luck retrofitting substantial masts and rigging to existing ships.
@stavvers I wonder how long it will take before they a) realise you can combine kites with sails for even greater efficiency and b) it's quite hard to charge money for using the wind.
@stavvers this actually seems really good? its not practical to use traditional sails for our big cargo ships and you cant just retrofit big sails on something
@stavvers At first I misread this as "Giant kitties".
@eliocamp @stavvers
They tried that first, but the litter boxes were unmanageable.
@eliocamp @stavvers OMG, it wasn't only me ๐Ÿฅฒ
@stavvers whaaaaaaaat, that just sounds ridiculous. It'll never work.
@stavvers business plan: get acquihired by Sailsforce
@stavvers I wonder what happened to the 2008 version? Can't remember what the company was called...

@nebulousmenace @stavvers The article mentions something about SkySails. Never heard of them before, even though they were a German company.

Maybe the idea just didn't fly back then because burning heavy oil still was fucking cheap, YOLO.

@nebulousmenace @stavvers I remember too that I heard about it a long time ago
@stavvers giant kites. Whatever will they think of next.
@CatDragon @stavvers Remember when Uberโ€™s CEO envisioned ride sharing with way more people per vehicle and everyone was likeโ€ฆ โ€œso, a bus?โ€
@dreamwinder @CatDragon @stavvers it's a shame nobody has "thought of" doing a school bus like thing (where it goes to the front of your neighborhood or to your house) but not for school... because city buses use approved stops and routes, all of which are a two hour walk away (and are actually intended for Raleigh residents to get to a Wake Tech campus...)

this is why it's so awful to live in the suburbs, but alas, we can't afford to move...
@stavvers i swear to god i've been seeing this headline every few years for the past like twenty years lol

@stavvers Next up,

My kite is bigger than your kite.

To protect our customers our kites can only be used on approved 'kite readyยฎ' ships.

Certification for operating kite ships will be issued following successful completion of our KiteShipโ„ข course. In Seattle.

Kites are supplied as sealed units any attempt to dismantle or repair a kite will invalidate your warranty.

Kites using, for example, third party string or other non-standard accessories will cease to function.

@stavvers The world may be ready for my next invention... large-animal-driven cars. Thinking horses might work.
@stavvers
I guess it's annoying that anyone could get an inflated valuation from this since any such system would be sold with really narrow margins for the foreseeable future. But to be clear it's not "sails" & it's not stupid, it's just not cost-effective at present.
@stavvers "Pirates Redirect Containership of Apple Devices By Hacking Sail Controls"
@stavvers about time it was finally done amirite
@stavvers I would use Timelord technology and stuff it all in a mini-submarine.

@stavvers Okay, but in fairness they invented sails of massive scope that could catch winds above the sea-level wind and would be tethered via sturdy cable.

โ€ฆ so, you know, way more dangerous sails. ;)

@stavvers they never fail to disappoint.

But will those kites have the ability to self-distruct?๐Ÿค”

@Jiriki @stavvers
There are many options to achieve this , mostly by not looking where one's going.
@SoftwareTheron @stavvers I'm sure they'll excel at this, or invent Google glasses for seeing in the distance.
@stavvers "leveraging wind currents going forward"
@stavvers Let me guess: you have to lease the sails and if you stop paying they disintegrate, but actually it's all due to a cloud service so sometimes you're in a dead zone and they disintegrate anyway?
@stavvers These are more akin to what some catamarans have on board. Their version of it in basic terms is a kite attached to the bow that can be used for free propulsion and fuel efficiency. Not a bad idea.

@stavvers "If only they would loosen up those pesky child labor laws, so that someone could fly those kites..."

(Yeah, I'm aware of the technology that they're talking about, which makes it all the more laughable, because they've been talking about it for fifty years and still haven't gotten the media a picture that doesn't make them look dumb.)

@stavvers Oh my Lord, this is so much funnier than when they invented cellars a few years ago ;)
@stavvers This sounds awesome until you're crossing the North Atlantic and a bankruptcy or a bad update bricks your propulsion system.
@stavvers to be fair, they already reinvented trainsโ€ฆ.

@stavvers TBF this is a GOOD idea purely in engineering terms: kites can take advantage of wind speeds and directions that vary at different altitudes, aerofoils bolted to the deck on rigid masts are limited to surface winds. But it's still only a supplement for engine power: modern supply chains can't cope with VLCSs getting becalmed.

The real answer is marine nuclear propulsion. Or teleportation booths. Or sparkly unicorns. Or something.

@cstross @stavvers and the kites operate at a higher height where the wings should be faster and more reliable.
I love dunking on tech bros as much as the next mastodoon, but if they can make it reliable and cheap, then let's take every weapon against climate change we can get.
@cstross @stavvers I read, somewhere, that it takes an implausible amount of kite to equal the power of a ship engine. My brother's been messing with kites for decades, one crucial piece of equipment is the device that lets go of the kite fast, not sure if there needs to be a ship version of that.

@dr2chase @stavvers Here's the LARGEST diesel engine in the world, per wikipedia, the Wรคrtsilรค-Sulzer RTA96-C. Two-stroke cycle, 14 cylinders, puts out 80MW (or about 107,000 horsepower), weighs over 2,300 tons. Used for powering 170,000 ton (and up) container ships.

It's hard to see how to replace a medium-sized city's power station with any kind of sail (or to abolish this scale of shipping in a century when climate change will cause frequent local crop failures).

@cstross @stavvers The big advantage of kites is that they're completely retractable and don't affect vertical clearance, which is strictly limited at most cargo ports due to their loading cranes (preventing the use of masts).

Also, even if this doesn't replace engines, it's still quite useful. There are some long-distance ferries in the pacific islands currently using a combination of sails, solar, and diesel generators (running scheduled service between high-clearance ports) that saw an over 90% reduction in fuel consumption compared to their predecessors. Kites could possibly expand this to low-clearance ports as well.

@stavvers boats crossing the ocean powered by nothing but wind!?

What a time to be alive.

@stavvers this one is actually legit. Modern container ships canโ€™t use traditional sails because the rigging would interfere with the containers themselves, so folks have been looking into using parasails or rotating cylinder sails instead.
@stavvers They will call it smart sail.
