Super easy to retro fit to be able to pull it out the water when its a light wind too, great for anybody wanting to reduce using their main engine as a battery charger.
Solar is great on sail boats but often the sails block the sun when they are out so its difficult to get full utilisation. Something like a hydro generator works perfectly with a good sized solar install for a sail boat to cover at anchor and under sail.
So I was talking about hydro generators that go in the water rather than a wind turbine that rely on direct wind. I prefer the former as it doesn’t muck up the aero on the boat (sails can rob it of power with their dirty air) nor does it get in the way of the deck space that is often limited on a smaller boat. You could use both but I am not fan of wind turbines except at anchor.
With a normal sail boat its common to have more wind that you can safely handle with the boat, you can use the drag of a hydro generator, which goes in the water only when you need it, to help slow the boat down rather than reefing or reefing as much (intentionally making the sails smaller). As wind is the only thing generating motion for the sail boat, its free energy that you otherwise would not be using.
Motor boats rely on the motor to move them, so any drag means the motor has to work harder, imagine dragging a drogue (water parachute used as an anchor), its the same thing, its no longer free energy and you are actually spending more energy moving the same distance as the hydro generator doesn’t generate as much energy as it costs to use. Its the same problem for a wind turbine, as that increases aero rather than water drag for the motor boat, requiring more effort from the motor for the same speed & distance.
Motor yachts would be better switching their engine over energy generation as a generator for recharging the EV batteries. Indeed there are some bigger motor yachts that do exactly this as a backup to their solar and dock derived power.
Such high winds impacts motor yachts as well, especially high sided ones. Most of the boats I’ve sailed are without bow thrusters require lines to manveur in even moderate winds in tight marinas. Bow thrusters makes it push button in moderate wind.
Super rich all have crewed boats, so its mostly to do with living space per foot of boat length or them as they just pay their way around the skill issue. Those who do like to occasionally pilot or race their own boat tend to have sailing boats as they are much more rewarding to sail.
The bits that are different between a motor and sail yacht is really just the sails, that part is actually pretty simple to learn (mastering is something else). In mast/boom mains, electric furling head sails, hydraulic or electric winches, all make operating the sails push button.
The navigation and marina skills are the same, if you have bow thrusters. As everything else is at a slower pace, sail boats are easier to get to grips with when under way and new to sailing.
I completely get that not everybody wants to tack their way upwind, but its the pleasure in actually sailing in silence rather than a noisy and smelly motor that is the reward here. That, and the cost saving. I can do two weeks sailing covering hundreds of nautical miles for £50 in fuel for a 40 foot sail boat and that’s with having to run the motor as a generator to charge the batteries (charter boats suck for house electrics and solar), vs. £500 ish for a motor yacht.
Big part of this would be that its a foiling boat and that massively reduces drag from the water. Keeping weight and drag down are the secret to improving efficiency for EVs be they boats or cars. Any decent marina its easy to get multiple 22kw shore supply as well, it can be expensive and metered but you aren’t going to be waiting that long to recharge your boat.
Electric makes the most sense on sail boats as they already have a green source of energy, and thanks to hydro they can convert some of that motion generated by the wind into charge for the batteries. Couple with solar and you start to look at a decent amount of energy generation.
Sail boats also tend to have far less powerful ICE than your average motor yacht, so you need less powerful EV motors to achieve the same speed, and in the right conditions you only really need the motor getting in and out of the harbor so your battery bank is smaller and lighter. Plus you could make the batteries do double duty as the house batteries as well.
The trick will be to get the super rich out of their shitty super yachts that burn a couple of thousand dollars of fuel per hour, they could already have sail boats but choose not to for the increased living space that they can get out of the same length of boat due to being able to build much higher due to no masts.
I disagree with that for thumbs, mine tend to be much flatter against the keyboard than my arched fingers, so I can hit the split space and mods easier with my thumbs if that row is at least 1.5u and preferably 2u for at least the split space keys. 1Us on the bottom row forces me to either contort my thumb or even worse, use my fingers for the bottom row.
Worth pointing out that the majority of tourists in Japan are in fact Japanese, at more than 80% of tourists. Next largest group are from Japans closest neighbors in East Asia. Its a minority of a minority that cause all the problems.
I’m only ever logging on because there’s a problem, so i login infrequently, like may be every few months.
So i want want to see the os version as I have some downgraded on purpose, and that’s helpful to see. I also want to see uptime, disk space, ip address, ram, and kernel version. These all help me understand basic issues if the box is rebooting or needs a reboot or it out of disk space very quickly.
Obviously, there are a million and one other ways to get this information, I could even stick them in my .zshrc to auto start on login as I’ve done with fastfetch, but why on earth would I do that when fastfetch works, takes less than a second to run on sign in, and looks pretty?
It’s not like I am not launching a connection to them 100s of times a day.
Ya know that never occurred to me that would work, going to have to try it
I prefer fastfetch, but I have to compile it for my PIs as i couldn’t find a precompile. This is painful for my zeros that I use for my automated watering system, so those have screenfetch. I find fastfetch faster for my options.
Completely get why some people don’t like them, but I just love the ease of seeing all the stats I want when I login to one of my boxes I don’t log into very often.
Always been a bloke in the pub or car boot or whatever that can supply hooky dvds or games or hacked satellite, FAST always talks tough about busting them.
Early eights it was disk and tape trading, mostly tape trading in the UK. Was a way more social activity.
Late 80s and early 90s, it was all disk, and you really needed a connected friend who could get the menu disks (custom pirated compilation disks). These were often super hoarded, only traded for a lot of games, like certain private trackers today.
Very early web stuff was all usenet and ftp servers, often hosted at a university. If you knew where to look, anything was accessible.
Early 2000s was a golden period of easy access. It would be slow, and the quality would often be low if it was a video or mp3. It’s gotten harder to find the obscure stuff as time has gone on. I
t’s like the scene only remembers out and out classics or the latest thing outside of some niche places.
He was also often very shit, Disney land Paris, for example, that was a huge fiscal drag for decades. A lot of the better stuff he is credited with was due to Wells influence or in spite of him.
Modern disney collapse is due to Chapek, and in particular, why the budget was cut for Star Cruise early in its development. Iger is far from perfect but better than Eisner and Chapek combined.
UK desperately needs more pull thru spaces. Having to unhook to charge is painful
In the UK APNR cameras are starting to roll out to some providers to automatically issue parking fines to people icing charging spaces or people hogging spaces after they finished charging. I think this will be needed in the short term, was particularly needed in one very busy car park I’ve used to keep ice cars from parking there as there nowhere else to park.
One of the key reasons traditional manufacturers were reluctant to build EVs is because of the batteries needed and their lack of ability to make these themselves. A battery on a brand new EV can be half or more of the total cost to build the car, who wants to pay somebody else, who is going to expect to make a profit on the batteries they sell, half the cost of the build to a competitor or third party for any true mass market car? You cannot start to compete on price or volume till you make your own batteries and cut out that profit of the third party.
When it became clear that the Traditional Manufacturers could no longer avoid ramping up EV production as Tesla and latter China/Korea were stealing their future market they have shit the bed, begging for subsidies to build their own battery factories and recruiting staff with experience. Its going to take a few years before these factories come on line, but till then you will see them pushing things like PHEVs and halo EVs like the F150 that they do not plan in selling in large volumes in favor of ICE that they make the engine.
There is also an element of the speed of development of EVs, they were clearly caught out how fast the market moved with efficiency and thus range. As an example, the early VW group EVs were awful, at least a generation behind the best from Korea or Tesla. The latest ID7 and A6 etrons show that VW have acknowledged their mistake, the saloons made on that platform (the SUVs on the same platform just cannot compete due to worse drag and weight) seem to be aiming around 4 miles per kwh, which is extremely impressive for such large saloons.
Improving efficiency is the key to reducing battery sizes, which reduces weight, which further improves efficiency, but most importantly reduces the cost of EVs. We need to move away from 100kwh+ batteries, they are a crutch for inefficient, bricks of SUVs that are far too large and heavy. Manufacturers just up the battery size to counter their poor design decisions, which leads to disappointment when you realize you struggling to get 2 miles per kwh from your 2.5 ton EV9 and its only doing low 200s out of a 100kwh battery.
What you are describing, for it to be of actual benefit, is at its minimum a perpetual motion device, as that’s what a zero loss system would be. Only people working on that also sell snake oil.
Anything less than 100% is a loss, which is going to be larger the heavier the car is due to friction (aero, drive train, and rolling) and extra energy to accelerate, that’s basic physics.
Very large batteries, 100kwh or over, solve what should be a medium term problem, they are an expensive dead end as they are often around half the cost of the car’s production cost and add . What I really don’t like is stupidly large bricks of cars that struggle to even do 3 miles per kwh and then use a massive battery to get around their comically small range, which further lowers their efficency.
Yeah, hmm, at some point you have to stop, thats where the momentum or at least some of it is returned to the battety. The return from regen is less than the energy spent to accelerate and overcome friction, in the first place, so you get significant losses of around 20% or more, so not really…
No, hire car, not a taxi. You really don’t need to book months in advance to get one, unless you live somewhere with unusually high demand for them. Most places you van get same day.
PHEV emissions are only lower if you use the battery, majority of phev owners don’t even charge regularly. With the majority of miles on the ice ruins any gains on emissions. Emissions are only one part of the impact to the environment, brand new cars even evs have a higher initial impact that reusing an old car, especially one no-one will want in a few years.
Car weight is also a factor due to brake and tyre wear, and guess what, a phev is carrying around all the components of an ice and all the components of an small ev, way heavier than the old car, even ignoring that modern cars weigh more anyway…
It’s just such an unlikely set of requirements the number of people that actually meet it is pathetically small.
All of these have to be true for your example to make any sense: Commute distance less than the battery range, typically just under 30 miles
Able and prepared to charge every night as that commute has just drained the tiny battery, another poster has already pointed out that the majority of PHEV owners don’t actually charge
Cannot plan any long trips greater than 400 miles
Lives with no reliable hire car service
Lives more than 400 miles from a public ev charger
Somehow can do more miles a year to save money over buying an older, cheaper car that’s about £15k cheaper to buy
It’s just comes across as a bad faith argument, sorry.
