Re: [Electric Boats] Re: wave powered

 

Kirk,

Thanks for posting the link.   Motor/propeller driven boats may soon be banned from Glacier Bay, here in Alaska because the noise coming from their engines & propellers is detrimental to the whales.  Something like your post may be a good start on a slow speed, silent boat that "swims" along, while people enjoy the marine life.  

At anchor you could make electric power from the device.

I use a similar device to stabilize an offshore fish processing barge & make all of the hydraulic power we use for the deheaders & lifts.  When I installed the "fins" I got nonstop crap from narrow minded people.  Now, wave pumps: both for water & hydraulic are common.  Wave pumps for electric generation are starting to catch on.  I hope to have them on my barge next year since solar panels do little in an area of the country that receives 200 inches of rain a year.

thanks again,

jonny

 sorry.

 I read where you have to retract it if you encounter weather and that sounded like a lot of force. Prob not much use in the harbor

To the rest of the group, I apologize in advance for the following rant.

Seriously, Kirk? What was the point of this? What practical value do you think that this type of system would provide?

Why would anyone go to this much trouble to "drive" a boat at what appears to be a small percentage of the speed provided by a pair of oars? Where do you normally boat that tosses your vessel around like it was in a washing machine?

Even the "prototype" doesn't generate enough speed to maintain steerage. To me this looks like a novelty, and a fairly ineffectual one at that. I can't believe that this could move a full size boat any faster than a 65 year old Jack Lallane with his feet and hands shackled.

I am sorry if this sounds harsh, but there is already too much noise in the world. I belong to this group to learn and to teach others practical facts about Electric Boating and to help others convert their boats to electric successfully. Many of your posts are only vaguely relevent to this group, but this one goes too far. I'm sure that there are other groups of people that would like to discuss far-fetched theories with little practical application. Please try to stay on topic when you're here.

If this had been the first post that I read here, I doubt that I would have joined the group, and probably would just put a new diesel in my boat. Posts like this imply that electric power is just another crackpot idea by association. Try to think about the unintended consequences of your actions.

RE: [Electric Boats] Re: wave powered

 

Boat propulsion aside, inertial generators such as those in flashlights you power by shaking can be used to produce small amounts of storable electric energy.  There is a field of engineering, http://en.wikipedia.org/wiki/Energy_harvesting, also known as energy scavenging that seeks to glean energy that would be otherwise wasted in a larger process. It's possible there might be some application in electric boats.

Thank you for the reply!
I do not yet have the system set up, in fact I am just in the process of figuring out how to make it all work. And the way I described it seemed reasonable but at the same time like too many chargers involved.
But the system works properly the way you have it set up?
And as for the generator: You run it and just plug your shore power cable into the generator? So basically the effect is the same as if you were alongside and plugged in? Or did I misunderstand something there...

RE: [Electric Boats] Multiple source charge controller?

 

Well - as mentioned before, at least one vendor claims to do just that for off-grid systems:

 

"What is the IPN Network
Blue Sky Energy created the Integrated Power Net™, or IPN Network to provide both a charge controller communication strategy as well as create the next generation of Solar Boost MPPT charge controllers. The advanced high speed digital network, allows up to 8 IPN capable charge controllers to communicate with each other and operate as a single machine rather than separate charge controllers. The IPN Network also allows networked controllers to share an optional battery temperature sensor and remote display. The IPN Network does not require an additional controller, display or other special communication hardware or software to operate."

 

http://www.blueskyenergyinc.com/

 

I've no idea how valid the claim is but fwiw they did win an award from an RV magazine.

Ok, but it at least allows you to pull from multiple devices simultaneously.

 

I would be surprised if anyone had a device that could mix and match multiple sources and get peak efficiency from each - though that would be great!

 

As mentioned, the micro-inverters sound like the closest thing to that - but they don't (yet) exist for DC (that we know of).

Wouldn't  it work to run each power source (except for grid battery chargers) through a diode, and then the parallel of the diode outputs into a single charge controller??

I suppose the proper way to do it is feed each source into a maximum power point tracker  and sum the outputs of those into the battery pack. They all share the same battery algorithms so sharing should not be a problem. If the battery is in danger of overcharging the propulsion motor is a convenient load, unless conditions don't permit it.

Hello - an old lurker here, but have a quest I'm sure a wise person in this group can help with. I'm looking for device that will take inputs from multiple power sources such as wind/water/solar/shore power/on board generator etc and control the the charging of a couple of battery banks. Can anyone give me a lead?

Thanks - Nick
