It's Coming, little by little

[CUDA]

All we need is some of that new battery tech, I would only be interested in use on Tender.

The "big" one is 8hp... that's pretty hard to get excited about.

How is you live on a boat plan coming? Is cruiser boat insurance reasonable? Do you move the boat before a hurricane or leave it in place and hope?

[CUDA]

They also sell a 335hp electric motor for inboard applications, I wonder how much juice it takes to run ?

Because I'm looking at a marine 12,500 K generator that uses a 3 cly Yanmar diesel, it sips fuel, just like the Chevy Volt

Mercury has a good idea with the small motors, I'm going to the Miami show next month, and I'm sure new chit will be displayed.


As for dream boat Jimmy, Diesels with large props are the only way,I'm driving to Palatka Fl next week to look at a 55 ft with Yanmar 440hp motors

In the design boat I want Cummins is hard to find, everything is over $200,000. and I want a 50,000 lb lift

I rather spend money on a boat house lift. The St Johns river in the Palatka area is a good place to be during hurricanes,

No Idea about insurance, but I'll take whatever courses I need to reduce, Insurance in the NE of Florida is cheaper than the southern area

I believe the wind code is 110 mph east of the John's River and 120mph west, in South Florida where I live it's 180 mph.

I just officially retired,

I think electric power for high performance boats could really be interesting, but as we all know, the common demonimator here is the battery technology. I think there needs to be major advancements in battery technology for electric marine power to become even close to mainstream. Isn't the solid-state battery tech supposed to have high expectations for that? I know Toyota was really pushing development there.

From my fellow nerd camp the real world on the solid state deal is maybe 10-20% better with some more hurdles yet in the way. Power storage will be kick off for electric to go big some day, it will happen but not for a bit yet.

[pcrussell50]

It’s not the motors that are at issue here. Electric motors have been at or above 90% efficiency for pretty close to a hundred years now. Some are over 95% efficiency now. Big whoop. 90% efficiency would be fine.

It’s the batteries.

We’ve been stuck at lithium ion for coming on 35 years now which is an eternity in the tech world. It’s a BIG problem. We’ve known about solid state batteries since the early 1800’s (not a typo). They’ve been “just two years away” for the past ten or more years. And the same problems remain as existed two hundred years ago when they were invented. (Extreme cost and extreme fragility as you scale up size). Otherwise they would already be mass market items.

That's easy mate. Simple arithmetic problem. 335hp is about 250KW. A 1200 lb Tesla 100KWh battery would give you about four tenths of an hour running time at 250KW (about 24 minutes)... At least while the battery is brand new and hasn't lost any capacity.

I'd say that Cudes analogy of technology creeping along, little by little, is not the apt analogy. I think it's more like one great technological leap at a time, followed by decades of being stuck, then another technological leap.

Makes sense. At the end of the day, the first "solid-state" batteries used in cars/boats/airplanes with be something more semi-solid, and not as able to deliver on the promises of actual solid state.

they are building the plant now, in the USA.

LOL. So full blown solid state batteries for cars/boats/airplanes is already here. We're just waiting for the factory to be built and then we'll be all in on it? LOL.

The only real world way to make those big OB's work would be a hybrid setup, with diesel Genset powering the E motors, like a tug or train. But I'm not sure what the overall benefit would be on that. Certainly not initial cost. Possibly running/ operational costs. But if youre planning to catch Jaws, you may need a bigger boat, but you'll be good on torque in the motor department.

At any rate, it's always fun to spitball concepts. Never know what will come of it.

True, not so much for planing hull recreational boats. But This is already feasible for non-planing hull applications in very large hulls. Think container ships. BUT... It would raise the cost of shipping by quite a bit. And I imagine the shipping business is competitive. Nobody is going to voluntarily raise his own cost of doing business while the others don't. It would require government force. But governments don't want get caught doing things that make it harder/more expensive for their people. So they have to cook up schemes where they don't get blamed at the ballot box, for the cost increases. So here we are.

That's kinda why I gave the application of tugs and trains. Both have been in use for some time. Natgas as well could be used for the Genset fuel. It's a matter of imagination, and calculating the up front cost vs operational.

I can't help that you are

If you do some reading you can solve that PROBLEM

The Chev Volt of boats...

Last week I bought a 55 ft 14 ft wide water home, repowered with twin low hour 440 Yanmar diesels, upper and lower helm.

It has a hardtop so I'll be adding solar a big house battery setup, It has a new 600 gal fuel tank When they replaced the gas motors with diesel.

55 foot X 14 foot is huge. Post a picture or ten, inside and out.

I think diesels is the right call for power.
