Very interesting. Thank you for compiling this information. Very well done.
great video , interesting well edited fun to watch and learn too!
Props to you for such a good video. It is very informative.
Thank you YT Algo, yet again I'm never bored
👍👍👍Lots of amazing ideas, very cool video!
Thanks for watching!
Thank you for the mention in your channel, we have done many improvements on the jet since then, and testing DeepSpeed technology on different laboratory boats! 😉
Always great stuff keep it up
Thanks!
excellent. Thank you.
Interesting , thank You. happy searching
Great video.
Wow, nice video
Very surprised you didn't put in the Voit Schneider system
That's "Voith" (not "Voit")... but yes, it's an unusual and fascinating design.
Im working on getting a 60ft houseboat and want to convert it to all electric and solar charging system to run the inland rivers (tenn, miss, ohio and so forth)and anchor out with just having to come in for supply's and working on which way would be best to go
The sailing community is getting into these
That awesome propeller i've ever seen.
More like this to come, i hope !
👍🏻🙏🏼🖖🏼
Back in the 1990s or the early 2000s on discovery channel they had a blade less electromagnetic induction engine which is more like a pod with double Venturi’s I have not been able to find it ever since it was being used as a dredge also. It would be interesting to see whatever happened to it thanks for the videos!
I will try to find it, thanks!
@@Tech_Planet great thanks 👍
John mayor, I remember what your talking about. I think I read somewhere that the navy bought the rights to that technology.
It is called a magnethydrodynamic drive. There have been german and US prototypes tested with it. It is likely hideously inefficient. The very strong unshielded magnetic fields and high electric current going trough the water probably make it very easy to spot. Corrosion and fouling of the electrodes will be an issue limiting operation time to a few hours at best before they need replacement.
@@pyalot They tried it on submarines to make them silent.
Motors in air motors in air and now motors in water, good video 👍
Thanks!
I see a return of some very eligent small yatchs with silent propulsion
You should have a look at the Zparq motor.
I've been in the market for a small CPP for years with zero luck. In the end I started designing my own. Thanks for the info!
What is your application? May I ask.
I'm designing a new engine for my steamboat; it's half 'Smart car' engine with a new cylinder block and valve chest. No way to reverse it so a CPP seems a good fit.
@@wanglydiaplt wow. That’s uncommonly interesting.
The strangest is is steam that is designed to shoot out the place where the prop would be. Because of the huge expansion from steam it produces a large thrust.
Hydromea makes an electric motor similar to the RIM 6. The Hydromea motor sells for about $500.
I these sorts of motors are a good fit for small unmanned submarines. Since there's not a center hub, seaweed and other debris just pass through the center without clogging it.
I'll post a link in a separate reply incase direct links get caught by the spam filter.
Thanks for another fun an interesting video. I always like the unusual gadgets you find.
Ok thanks for letting me know! I will double check and make sure the link comes up for ppl to check out.
Nice find! That disc drive looks really interesting - www.hydromea.com/diskdrive-thruster-technology/
@@Tech_Planet That's the one. It's pretty cool but it is also a lot more expensive than other options.
The lack of a central shaft also means that the bearings are around the rim, so both the bearings and the seals are very large and have a very high tangential speed with lots of drag.
@@brianb-p6586 The Hydromea Diskdrive doesn't have any dynamic seals. It has to run while underwater since it uses water to lubricate and cool the motor. I'm pretty sure it not a very efficient drive but the ability to deal with seaweed and other debris makes it a good fit for some applications.
the plural of craft is craft, not crafts.
Get over yourself
what's so unusual about counter rotating props on a single drive? Old tech, been around since the 1970's on outboards and inboard/outboard drives. Been around even longer in the aviation industry; both military and civilian aircaft.
Way before the 1970...When used by Volvo and Mercruiser it was already a mature technology.
It's presumably unusual now in boats. In aviation, it is technology found in museums, not in flight.
Some weeks ago, my dad told me about a strange propeller he had come across. Seems he was referring to a Sharrow one.
You showed a white boat in Amsterdam named Pax as an boat with electric prop. This boat is still floating with batteries but have have prop with a diameter of 47 cm. This boat have a package of 84 batteries what is good for one week floating. I was captain at this company. This boat was build with a Fort Mermaid diesel. In the winter of 2016 this boat get a new Volvo Penta. About one and a half year ago this boat was rebuild to electric.
When I was traveling in India, I met a guy who owns a putt putt boat factory. Those are the little toy boats that run on a candle flame. The guy said that when he was a kid, they would putt putt around the Ganges River in a boat powered by a putt putt motor made out of a hollow steel walking cane.
This video is awesome
Thanks, I appreciate it!
I'm all for it but I am curious how they deal with electrolytic and galvanic corrosion in the pod motors. I am sure composite materials are used but the actual motors themselves seem like they would be susceptible. Any word from the manufacturers on how they deal with it?
you can add corrosion reducing "targets" into basically anything, they use specialty alloys usually zinc based to cast little bolt on things to be easily replaceable. These objects are preferentially "targeted" by the galvanic effects, and you just swap them out when they wear out. There are many varieties to suit specific applications. (I'm not a manufacturer of these things, but have used them extensively in boating and commercial fishing (refrigeration systems using seawater to chill fish need many of these inside their heat exchange units, for example)
@@adamh1228 Wow! This was from months ago and I actually forgot about commenting. Yes, I am familiar with sacrificial anodes. I have owned boats and had them in my family most of my life. My current boat is fiberglass but I am actually interested in an aluminum catamaran and am cautious but not overly concerned because I know it is manageable with proper care, regular anode replacement and isolation transformers to reduce stray current. However, having an active high power electrical device below the water line opens up an entirely different level of corrosion. I am sure they have considered it and I am definitely not suggesting it is impossible, I was just curious what steps they have taken to mitigate this issue. Cheers!
how soon will it be on mark it ?
What happened to the Voith Schneider Propeller
It is far more unusual and has a commercial history of successful deployment
Very interesting..
Ohh what works of engineering work ! !
I'm a Diesel guy & would like to see an investor group improve Bio-Diesel so it's not so easily contaminated. I'd also like to see eBoats as well as petrol & hybrid because a greater number of alternatives is great for consumers. Not everyone is the same, despite what some ideologs(you could also call them totalitarians) are telling us.
most motor yachts over 60' have onboard fuel polishers that have serviceable filters because getting any uncontaminated fuel can be hard. Most motor yachts over 80' are hybrid diesel electrics, they have notable benefits. they could build diesel electrics for 20' boats but you see, real-estate and weight capacity are at a premium on a 20' boat... I'm waiting for solar cells to develop, a sail on a sailboat could hold a lot of solar power but they're still to delicate and still to heavy. Outboard motors are easy and cheap to convert to electric.
@@dirttdude I don't ever want to see solar cells on the water. The refined lithium & cobalt powders or cakes(doesn't matter), are incredibly poisonous so exposing a damaged cell to water is suicide to fish/plants. Alternative Energy is a hoax & the Green people have shown that when they want something to happen, they don't research the product nor consider the consequences. All Wind/Solar Farms must be decommissioned & dismantled. Their tax subsidies can't go to more worthy goals. Bio-Diesel & an Opposed-Piston Diesel engine would be efficient & far better for the planet & not near as dangerous to recycle. The problem w/ Bio-Diesel is that it's too friendly to microscopic organisms that grow large enough to clog injectors. Gotta fix that.
@@carmiethompson2676 i think you're too late to stop the tree huggers from using solar power to power their boats or whatever you're saying
@@dirttdude Whatever I'm saying? You don't understand English? You need to read my comment again...more slowly. Because you inadvertently made my point.
More underwater footage!
Never think about carbon fiber props. they wear out way too fast!
3:48 is this Kotor Bay, Montenegro ?
Imagine the Sharrow props being made of gold or Argentium?
Unless you are cruising the canals of the UK none of this stuff will be ready for real world use for decades and even then it will be expensive. Boats require real torque for long periods and is why torque monsters like diesel motors are the most used short of a weekend boat which is gas. Even Tesla's have limited range on land. Now have that same tesla drag a dump truck behind it and see how long the power lasts.
Dove si può acquistare? Grazie
How bout the Magneto hydrodynamic drive? Yes, the one Jonesy detected? I understand that it was noisy and inefficient .
absolute silence? Hardly!
great ideas, but what happens when that huge heavy battery goes flat!
Same thing that happens when you run out of gas/diesel.
My company makes the gearbox for the CRVP drive
Looks like the arse end of a Long Lance torpedo 🤔👍
Everybody's getting ready for those new batteries from sila nanotechnologies going to be a big deal
An amoeba ate my brain so I don't think anything
You forgot the Voith-Schneider-Properller(VSP)
It says boats in the title so I guess that’s why no ship propulsion systems are included
Honestly the only situations where I see electric boats being feasible are catamarans given how efficient they are, and the large footprint allows for a lot of solar panels up top to compensate. But small boats like the candela just seem too unrealistic other than for rich people to show off to their friends for 10 minutes then back to the dock to recharge... $330k for a 27 foot boat with 50 miles of range CRUISING, 32mi at 30kts... lol, thats less than 30 minutes of run time, then back to charge for another 13 hours.
Proas are a little better than catamarans .
Well, there's always lakes and noise sensitive areas...
The endurance is a valid point, but I don't know why anyone building an expensive vessel with current technology would be limited to a slow 13-hour charge. One hour to charge from 20% to 80% is typical.
Variable pitch props?? Had them in coast guard in 80s and they were made in late 60s. Seen Alot of these " new" props (not as polishes) being tried on drag boats and unlimited hydros in 60s..... all new was old
Nothing strange. The usual old new designs about propellers and propulsion I've seen since 50 years and coming back by fashion cycles.
Really interesting propeller design, while fuel cell ev boating, imo, will be a likely standard for water craft (where green-hydrogen electrolysis, from water, will be the easiest to have access). Battery tech doesn't need to be waited on. Hydrogen infrastructure needs to start being installed.
Hydrogens a fallacy, it's seriously in efficient not to mention storage difficulties such as hydrogen embrittlement
@@Th3_Gael Batteries are so lite & make boating so 'efficient' (lol), not to mention how safe all that immediate stored power + water is... *muting the 'conversationalist'...
@@chadlymath I never mentioned anything other than hydrogen. Address the points, don't change the subject
In my opinion, hydrogen is the future. I have read of much development and improvement in the way hydrogen is made and store and of hydrogen fuel cells. I think this makes more sense than batteries.
👍and 🍻
They probably work with marine gensets too, since batteries are still terrible.
Yeah, batteries have a ways to go in terms of energy density.
Yes, diesel-electric marine drives are very common in large vessels.
The Australian "K" or boomerang propeller was an original, more efficient design
Most Unique!!! Really?
The only thing strange was the nice man's accent tbh.
I'm not the best commentator lol
Battery technology is already here ! They got electric dirt bike out now stomping 2 & 4 cycle dirt bike like a step child ! Better believe it !
This is very good sistam ❤
DID HE SAY RIM JOB?
Its going to be a longgggggggggggg time before we see electric outboards matching the power of 8 Verado;s. Instead of wasting time on electric technology, we should be improving carbon capture and engine efficiency.
I invented all of these 10 years from now
Electric is NOT going to work for general use. Why the push, is the question.
Maybe you feel like someone’s coming to take away your gas outboard but that’s not true. This is all private tech money. It’s part of natural selection in the free market. The market sees a soo pop ace for this technology so it’s doing its thing
It’s not “advancements” but “advances”.
I want to know what I can mount on my yak , that is quite, won’t cost me a mortgage and one kid. Sick of paddling, arms hurt to much.
Here fishy fishy fishy
Catch a fish, let it pull you
@@MrJhchrist I’ve caught a few thousand fishy in my yak, non of them cooperated . Maybe I should fishy with clothes on,,,,,,,,,,,,,,,,,,,,, naa Fhak that ! 😬 🤣🤣🤣🤣🤣
Inches ? Feet ? What decade are you guys living in ?
It's not the decade, it's the country.
It would seem to me that mixing electricity & water is a bad idea. There are just too many ways for Murphy's Law to cause a short circuit that would be detrimental to the health & well being of humans that are too close.
It hasn't been a problem so far... but electric marine propulsion has only been used for about a century.
The plural of RPM is not RPMs.
Jesus man
None of this crap is for the average consumer.
Or reliable enough
Okay, dear marine engineers, please, use electric drives (less service, more reliability) and inexpensive diesel generators mixed with batteries. Thank you. This is the case on larger ships, so why not integrate it into smaller boats.
Alternativy, people can decide between batteries, diesel gens and a hybrid mix. That's all we need. Peace in the World is established
I've seen an hybrid diesel for sailing boat, you could move the boat with the diesel while charging the battery, you could sail and use the propeller to recharge or use the electric motor to move the boat.
you really need to pronounce you words clearer. When you talk fast I can't understand a thing you say.. I have to turn on the CC and stop the vid if I really want to hear what you are saying.. Other wise well done.. some innovating ideas.. Most I had never seen thanks for the vid..
All useless high cost with little pay out
Not really more like first gen tech most of these are just prototypes
