It would be a muscle hybrid powertrain sense for a boat?
I am planning to build a muscle-powered passenger boat, using the pedals like a bicycle. Now one of the challenges we face is the transfer of human movement as much as possible to the propeller. Not Sure how much of the friction loss is using gear configurations steel or other, but I just had this idea pop in my head instead: What if the pedals took only an electric motor that generates electricity from direct current, which is then transferred directly to an electric motor driving the prop? The advantage of this would be that I could give solar and wind energy around the issue somehow (which you need a little more brooding, as know). But we must do at least a little sense, or is totally ineffectual?
Tahini: You must concentrate on the muscle "to power generator electrical "interface with which to generate electricity or drive the boat. Reason for warning me" ": 1. Muscle Effciency. One of their problems is the large difference in the efficiency of human muscle based on their speed of contraction (nearly 100% to perhaps 10%). The equivalent of The automotive industry is the famous "Torque vs RPM" plot. Your muscles actually perform like a race car, his plan of being a strong "needle" in compared with a flat torque curve more desirable. By the way, is why so many needs a bicycle "speeds": It is never optimal pedaling RPMs. 2. Physiology: Your heart "operates" in an average of <50W. However, its maximum load can be up to 1000W (1.5 HP). By the way, is why a man pedaling a bike is so "superior" to any gas or electric "motor assist, which provides maximum performance only when the engine weighs several times as much as the bike. ==> 3. What I get is that "constant pedaling RPM" is not the best or even a convenient way power generation / movement. You must study the physiological load cycles, and especially the driver seat of his position before the end of the train drive passenger in his boat. For example, a constant repositioning of the controller can give a much better performance by as much as a factor of two. Please account, there are a lot of information at your university library in the physiology of the Aleutian paddlers Inuit kayak (no kidding). They are the highest efficiency "propellers", known among us humans. In addition, you may want to consult the database on the physiological pedal-powered "Gossamer Human Albatross flight "of the project. I do not know if it's still around, but Dr. Paul MacCready of AeroVironment in Los Angeles has spent years studying the problem. MacCready also was a professor at Caltech in Pasadena. ---------- Finally, please take a look at the first serious attempt at an electric bicycle. To be introduced shortly here in the U.S. Schwinn. The components used on that bike, lithium polymer battery, the drive shaft (ie, no chain) and the 6-speed planetary transmission could also be ideal for your project.
