Capturing Wake Energy Without Drag ?

Questor, please dont limit the speed atainable- the energy must be harnessed, focused into a refridgerative process to freeze the water for a low friction interface such as skates, with correct geometry its all down hill & high speed. All the best in your endeavours from Jeff.

 

LMAO..a clever twist on 'I want that 30 minutes of my life back please!"

 

Hidebound traditionalists seem to be all I ever meet whenever I go near boats or even mention them. I'm looking forward to my first sailing adventure with a salvage value expendable sailboat. First thing I'll do is sell the sails to raise money for a case of beer. The beer is an essential catalyst to free the creative mind. The empties can be sealed up with duct tape and taped to my life jacket for extra buoyancy in case I need it.The second thing I'll do is trim one third off the top of the mast. I feel that most masts are too tall in relation to the boat and at almost 60 years of age I don't intend to sail with nothing more than my toes in the boat. Next I'll take some poly tarps I've collected from scrap cars and try to duct tape together both a junk rig and an outrigger canoe type sail. I won't leave the dock without both a tailwind and a paddle just in case the sails don't work. Whether the boat succeeds in leaving the harbor or not is somewhat irrelevant. I'll be in my glory as all those indignant traditionalists scurry about the harbor with petition in hand trying to drive me out of the harbor. In the event that I make it out into the ocean , the sails fail, the original tailwind doesn't reverse and I'm not strong enough to paddle back, I'll bring an extra case of beer for insurance. With enough beer to spur creativity all things are possible.

 

..I suspected all along we were being had.

 

How many times do I need to say TROLL. Please stop feeding the troll!

 

Dennis, do you want to be the one responsible for making trolls extinct?

 

Coming to the realization of the falling pebble acting as a catalyst to release latent potential is probably the first original thought or discovery I've experienced in the past five years. It explains why it was always so hard to generate the perfect wave and also why it could only be done on the sunny side of the pond in mid or late afternoon.Once I realized the impact of latent potential on the formation of the perfect wave I realized that harnessing the energy of the perfect wave for a perpetual power supply was unattainable. It will always take more energy to create the latent potential than the perfect wave will generate.

I've also come to suspect that when professors used to visit me to discuss their theories on subjects like three dimensional time they weren't as interested in exchanging ideas as much as they were interested in learning to dummy down the explanation of their theories so that they could explain them to people outside of their faculty. They probably figured that if someone as dumb and illiterate as me could understand what they were trying to say then anyone would be able to understand. Regardless of their motives we did have some very good times. That's the second original thought I've had in 5 years. At this rate I should expect another one at some point during the next three years if I can somehow slow the progress of Alzhiemers.

I'm a little disappointed in where the thread has gone.A combination of stagnation within the minds of the design community and fear of the trolls has resulted in no one else bringing forward any suggestions. I think it should be pretty easy to come up with something that recovers greater wake energy for propulsion than drag. Another factor of inhibition may be that designers don't want to be associated with a boat that looks like a cross between an airplane and a trimaran. Despite the shortage of innovative suggestions it has been a lot of fun so far.

 

Hey I got sucked in too. However its still entertaining.

This one is a beauty!

I think we all know a boat that fits that bill already. Must not reply!!!

 

A while back someone mentioned that mounting the wave arresting-lifting-power generating wings with springs to prevent the wings from digging in too deeply would result in too much loss of energy.In order to prevent a wing from digging in on one side and overpowering the boat I've come up with a second generation advancement that addresses both safety and efficiency issues. The second generation proposal is to mount a stylish curved single floating wing mounted on a low tension composite bushing. The bushing would have just enough tension to hold the wing level while the boat is at rest. As the boat leans into turns the wing will tilt in relation to the boat so that it can remain stable on the outer edges of the wake on both sides of the boat.

 

where on the boat will these wings be mounted and how much wake will there be that close to the hull that the wings could take advantage of?

- me too! I'm also a bit surprised at your disappointment at what you seem to perceive as lack of innovation in the boat design forum. How far into this forum have you actually got? Have you checked out foiling sailboats, kite sails, concrete submarines, sail-assisted power boats, wing sails, hybrid power boats, boats built from bottles ... ? Take a look around before you take aim!

Ok..I'll bite..


What about piezo effect ??

Stacked amorphous crystals,with the lattice being inboard and being flexed by push rods??

But best to use polyvinylidene fluoride,the long chain polymers interact.
Take that output,get a voltage/frequency converter and you'll have current flowing.

But then you'd need to carry a ton of batteries to store the energy.....or use it to split H2 off to feed into your engine as Brown's gas.

I've looked at quite a few of them. Most of the ones I found interesting contain vocabulary that is unfamiliar to me or involve costs that are out of my league. I'm also looking at everything from the perspective of my age,disabilities ,goals and budget. Given that I'm a scrap dealer I'll have no trouble finding a decent 25 to 30 foot boat I like for somewhere between being paid to remove it and $1,000. Once I choose the boat to develop I want to spend no more than $10,000 turning it into a mix of low power diesel drive and solar-wind-battery drive with a minimal amount of time and labor. Looking through that narrow window there's not much to see. I believe it's possible but there's very little motivation for a professional to expend any energy on that kind of project. Given that is already the subject of another thread there is no point in going further with that here.

 

Given that each boats wake is unique and changes with velocity, that can only be answered one boat at a time. I just realized I failed a dummy test a while back. Force applied to a wing that is spring mounted cannot be lost to spring tension because force on both sides of a spring is equal. That means that the second generation pivoting single wing may be an unnecessary evolution. That's almost as bad as not being able to defend the viability of the fixed and immovable object.
