How These Silent Superyachts Are Powered By The Sun

День тому

Solar-powered electric yachts have hit the superyacht market. Austrian-based Silent Yachts and Polish-based Sunreef Yachts are two companies working on developing this technology. Allied Market Research predicts the solar boat industry will grow 14 percent by 2031 to $2.4 billion. CNBC headed to the Cannes Yachting Festival to get an inside look at the companies building solar-powered electric yachts, and to explore the challenges the technology faces in playing a wider role in the future of maritime transportation.

This tech would actually be decent for house boats. For the most part they arent moving around all that much so over the course of a day you'd supply all your power and be able to charge the batteries so when you want to move the boat around you've got the power to do that.

@aspitola 6 місяців тому

Problem is 3mil$ price

@enargins 6 місяців тому

With a house boat, you could also have wind turbines, for when the house boat isn't moving. Perhaps they collapse when the boat is moving, and then you raise them up when the boat is anchored, so you're generating power from the wind as well.

For boats. 1. The weight of the battery doesn't matter. 2. There's no shade on the ocean. 3. The backup can be sustainable, aka. a wind sail.

@millanferende6723 5 місяців тому

I thought of that too, but a lot of area is lost and even sun area is shaded, when using sail. You are better off (I believe) using more solar panels, and a new "Sharrow" propeller which is 36% more efficient, that I don't see mentioned often on these shows. Imagine that! For the rest, you can have high-concentration solar panels, with external fennel lenses and internal high-concentration solar cells, that move on the inside to capture every angle of the Sun. Cooled by sea water, which can be used in a heat exchanger to heat internal water, or for radian floor heating. Imagine capturing 50% more energy (by maximizing efficiency at different angles of the Sun, having more efficient and cooled panels, and capturing the heat). While also having a new Sharrow Propeller for maximum efficiency. You could literally cross the OCEANS! At no further cost.

@darthkek1953 4 місяці тому

1. The weight of EVERYTHING on this boat matters and that's why SY have been fanatical about weight reduction and friction reduction. I've seen the extended hours-long interviews with the designers. 2. Yes there is. It's called cloud cover. We get it months a year in the Northern Hemisphere. 3. A true wind sail interferes with the solar collection, but they DO come with Kite Sails to help.

But it's obvious that you've memorized all the sales pitch lies. Lol Silent Yachts just filed for bankruptcy because customers are finding out that the performance doesn't match what they were promised. Diesel/electric hybrids are the only reliable option currently available! Which is why Greenline Yachts can't make their hybrids fast enough to meet demand, but Silent is going out of business! If solar was a viable option, they would be selling them faster than they could make them.

Advertising and Reality are different. In the brightest of Sun these can drift around fractional speeds. But the reality is they get charged at dock and then they run generators. Oh, didn't they mention each hull has a generator? When the Silent 55 was the first "solar electric" boat to cross the Atlantic an interview with the captain (an experienced Spaniard) said he kept the generator running 24/7 to get enough energy to cross in time.

@milkman3851 3 місяці тому

In the brightest of Sun you can power at the same cruising speed as most other boats without using the diesel generator, While using all comfort needs. It was the Silent 64 that sailed across the Atlantic and he ran the generators for 3 hours at a time because, he was in a storm that lasted a week, with waves as high as 10 meters. He also stated that the solar was still collecting small amounts of power during that time. It looks like it did what they said it would do. Success Story. @darthkek1953 Why be so afraid of Solar?

Those yachts are definitely NOT "powered by the sun"; that area of solar panels would barely run the AC and icemakers. Boats like these use about 1-2 liters of diesel per km of travel; there's zero chance you could cruise the Med on solar power. For example, on the Silent Yachts website, the fuel capacity is 1000L to 1900L, hardly silent.

@darthkek1953 4 місяці тому

Yes and no. If you charge at dock you run on battery at very slow to a cove, if you don't run A/C and stay at a cove a day or two then you might get enough charge to return to dock. It's not impossible. But for passage making yeah you really do need the generators on several times a day. HOWEVER thanks to the large batteries MUCH of that journey is Silent if you're going cruising not racing speed the generators fill the batteries much faster than they are drained, so you fill the battery (up to whatever level) and then turn the generator off. If you're doing a high-speed dangerous passage-making (e.g. Atlantic) then that's when you have them on 24/7.

@KevinSmith-qi5yn 7 місяців тому

For a catamaran, solar can make sense. The ship is relatively light weight, it does not have as much drag on the water, and it has prolonged periods of rest while at port. Integrating solar panels doesn't make too much sense if the ship is meant to last more than 25 years. It means the ship will effectively be a waste product in 25 years. Unlike a steel boat, the fiberglass boat will also be more difficult at end of life. The solar panels will also have issues in both hot and cold environments. The batteries don't do well in the cold. The panels don't do well in the heat. For larger vessels, solar won't work. These vessels are constantly at sea, so they don't have those long periods to recharge batteries. It may help with crew conditions while waiting in queue at port. Nuclear is an option for the exceptionally large vessels, but decommissioning will be an issue and I don't think those vessels will be on the sea for over 50 years. One thing that is possible is to use an electric engine that is powered by both solar and diesel. There are periods where the diesel engine works less efficiently to maneuver or change a ship's speed. If it was possible to use electric power here so the diesel engines could be run under optimal efficiency, then the overall efficiency increases. But physically it may not be worth it.

Interesting points, solar wont be sufficient to fully replace combustion engine power but it can certainly improve the running cost by reducing the amount of fuel needed for voyages. Presumably the reduced fuel saved by solar would allow for greater loading capacity also, since cargo ships carry huge fuel loads as well.

Yes, solar panels are impossible to replace. LOL

Yeah because you never spend another dollar on your super yacht after buying it. Fixing solar panels after 20 years is definitely a deal breaker. Before you know it our landfills will be full of super yacht solar panels. 😂

Steel hulls would be a terrible choice, aluminium hulls on the other hand would be smart thinking.

Tipical modern information. You get all ecconomic informations (which you didn't ask for) and none technical informations. Speed, range, autonomy, how doesi t function, what about if there's no sun tc., etc...

@darthkek1953 4 місяці тому

Speed is up to 18 knots, range is dependent on speed but at displacement and in the sun, without A/C, pentially unlimited. After that, balances. If there is no sun or you run low, there is a generator connected to the batteries. So you top it up with diesel.

@gawainethefirst 6 місяців тому

You still probably want a gas/diesel backup engine.

@darthkek1953 4 місяці тому

They don't offer a diesel engine but every SY has a generator connected to the batteries. So it's really hybrid.

Imagine if it could use water or wind to generate power....

@Soldier53flyer 6 місяців тому

What's wrong with hybrids? What would you do if you're stuck in a storm? The onboard generator could not keep up!?

@darthkek1953 4 місяці тому

They are not considered hybrids in yachting because that has its own definition and companies like Greenline are in that niche. But they ARE hybrids in reality. Their generators are connected to the batteries and you can top the batteries up faster than the engines can drain them. In fact the Silent 55 that crossed the Atlantic had the generators on 24/7

Maybe solar yatchs can have a sail or giant kite for cloudy but windy scenarios. Regardless, this is just greenwashing for few rich braggarts with minimal impact.

they can go electric if they install a nuclear power plant inside it. otherwise no way. they consume too much

That amount of panels barley can power the inverters. This is a scam

@darthkek1953 4 місяці тому

Not true. I mean, yes if you're going at speed you'll be using the generators. But if you don't use the A/C then these panels will run both hotel (fridges, etc.) and engines.

@user-fy2uu3fz1p 3 місяці тому

From the pic ，there is not enough PVS to push it go fast. For the inverter it should apply the IP65 in this area. Currently it' a aux part but it's green.
