I think you're an idiot.
"JAXAshby" wrote in message ... ah, NO solar panels. I see. Just an alternator belted to the spinning prop shaft puttin out maybe 6 amps. So, let's add it up. 6 amps at 12 volts for 24 hours = 1,728 watts, which = 2.3 hp-hours. But you need 20 hp for up to 20 hours, or 400 hp-hours, or about 300,000 watts, which will take you approximately 173.611111 days sailing to produce. You would also need battery capacity of 50,000 amps. This is to motor not even 1 day. I dunno, joony. you think it is doable? Jaxass, looks like you can't read. I said, no solar panels. Not sure where you got $40K either. You're proving yourself over and over to be an idiot. "JAXAshby" wrote in message ... let's see if I got this straight. you guys are saying that between solar panals and a generator belted to the prop shaft you will have more than enough amps produced to drive a 20 hp electric motor for up to several hours, and therefore the public is going to stampede the vendor to pay upwards of $40K for a motor, panals, a few thousand pounds of batteries all to avoid paying $8k for a diesel engine, plus fuel. boy, you guys sure do have dreams, don't you.

At least the wretched public hasn't been doing so so far. Did you even visit the website? They are discussing hydrogen fuel cell technology, not lead acid batteries driving an electric motor. I believe you have missed the point they are trying to demonstrate. It's one of the reasons, although "abandoning" is probably a bit strong. Another is the potential ecological savings (although there's still a big issue with disposing of batteries), and there's the added benefit of more electricity available for whatever... washing machines. Who knows. "JAXAshby" wrote in message ... and *this* the reason people have been abandoning their ic engines in favor this great new technology? Actually, they do. The weight is distributed so it's not as big a deal as a hunk of iron sitting in an inconvenient spot. "SAIL LOCO" wrote in message ... Looks like another attempt by that electric motor company to sell some motors. They have been going to boat shows for years trying to get people to toss their diesels. They pitch people on the fact their motor weighs less and requires less maintenence. What they don't tell people is how many batteries they need.

Something you could do to make your argument more credible, stop using units of energy and units of power on opposite sides of an equals sign. Cheers Marty |

and the storage batteries to hold the amps until you can break down water is where? And how are they recharged? It *IS* perpetual motion to suggest that breaking down water into hydrogen and then "burning" the hydrogen to produce power AND amps to break down th hydrogen If you want 400 hp-hours of energy output, you have to have at least 400 hp-hours energy input. While I agree that the scheme is somewhat harebrained, and likely taken as whole comes out on the negative side energy wise; why store the energy in a chemical battery, why not use it to break the bonds in the H2O molecule and store the gasses? I think the energy required by the pumps to accomplish this would probably be sufficient to cause the whole wacky idea to come acropper. Cheers Marty |

So why would you put a "belt driven" alternator on a shaft that already has an
electric motor that can regenerate? And why only 6 amps at 12 volts? The system I saw can charge 22 Amps at 144 Volts. The net efficiency was such that they could power something like 1 hour for every 4 sailing. The battery bank was good for around 4 hours of powering, and a 10kW genset could run it fulltime (actually only running part-time to charge the batteries) with power to spare. This was a 47 foot catamaran. "JAXAshby" wrote in message ... ah, NO solar panels. I see. Just an alternator belted to the spinning prop shaft puttin out maybe 6 amps.

No, Jax. They didn't say anything like that. Really! Read it again..... slowly! Regards Donal -- |

joony, joony,joony. I just took you at your word, and then ran the numbers
out. Is it my fault what those numbers came to be, or your fault for what you said? I think you're an idiot. "JAXAshby" wrote in message ... ah, NO solar panels. I see.

jeff, about it. where does the power to generate hydrogen come from? How much
power is generated by "burning" the hydrogen to produce water? Is this more energy or less energy than it takes to split water into hydrogen? jeffies, remember what they taught you in those alleged classes you took on your way to your alleged arts degree in physics? You know, power in = power out. So why would you put a "belt driven" alternator on a shaft that already has an electric motor that can regenerate? And why only 6 amps at 12 volts? The system I saw can charge 22 Amps at 144 Volts. The net efficiency was such that they could power something like 1 hour for every 4 sailing.

oh, you mean horsepower can not be compared to watts?
Gee, the European engine manufacturers do it all the time. somebody should tell them you can't do that. Humm.... Something you could do to make your argument more credible, stop using units of energy and units of power on opposite sides of an equals sign. Cheers Marty |

storing gaseous hydrogen takes one ENORMOUS amount of space, while storing
liquid hydrogen takes some enormous equipment that takes enormous power to run. someone once was trying to come up with some "honeycomb" material that store gaseous hyrdrogen in high densities, but I haven't heard of them in a while. While I agree that the scheme is somewhat harebrained, and likely taken as whole comes out on the negative side energy wise; why store the energy in a chemical battery, why not use it to break the bonds in the H2O molecule and store the gasses? I think the energy required by the pumps to accomplish this would probably be sufficient to cause the whole wacky idea to come acropper. Cheers Marty |
