Interesting, but probably not with pocketbook reach of the common sailor =

The H2O part, though....If everyone switched to these = engines, not just on their boats but also other vehicles and other = machines (gas stations that pump water instead of gas) then won't we be = creating a different environmental problem? All that free oxygen = roaming around looking for a lonely hydrogen atom to hook up with? If = we went to a water-based energy system, wouldn't that ultimately affect = weather patterns down the road? What about the water shortage we now = face?

I wasn't commenting on the hydrogen fuel cell aspect - frankly the concept of
using an RO system to make pure water to make hydrogen for a fuel cell seems more like buzzword loading than viable technology. However, using electric motors that can regenerate through the propeller is viable and is being done today. If I were building a new boat, or repowering, I'd take a long look at the "Electric Wheel" approach. You talk about "power in = power out", but doesn't that mean that you should generate as much with the wind pushing the boat at 8 knots as you use when the motor is pushing it? That would mean that you could make enough to power the boat half the time. Obviously, there are efficiency issues, but with batteries able to store 4 hours or more of run time it starts making sense. Add in a small genset that can run very efficiently at a fixed load and you have a very viable system.

Do you think a 'special' prop would be needed? I've seen where a belt is
driven off the prop shaft to an alt. for batt. charging. Not sure if that's good for the trans.. But the elect. motor/gen. sounds ideal if the costs could be competitive.

"JAXAshby" wrote in message ... 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. 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. 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.

Well, a folding prop won't do much good! I think most electric conversions use
a large (like a 20 inch) prop. The new systems are set up so that you can set the "throttle" to provide some engine power when the wind dies, and then regenerate when it picks up. The only way to tell which mode you're in is to look at the charge meter. Costs are going to get competitive over time, especially when you figure that maintenance costs are much lower with electric power. Even when you include a small genset for the "diesel-electric" approach there's a big win in the long term "total cost of investment." "Scott Vernon" wrote in message ...

frankly the concept of
using an RO system to make pure water to make hydrogen for a fuel cell seems more like buzzword loading than viable technology. that's because it is. However, using electric motors that can regenerate through the propeller is viable and is being done today. no, it isn't. You talk about "power in = power out", but doesn't that mean that you should generate as much with the wind pushing the boat at 8 knots as you use when the motor is pushing it? it certainly does. otherwise, it is supposed to generate more energy than it consumes. Add in a small genset that can run very efficiently yeah, sure. "very efficiently", as opposed to what they do today and are likely to do for the next several centuries. a fixed load and you have a very viable system. ah, no. you *must* build a WORKING model to take that to the US Patent Office, for they require that in the case of perpetual motion machines. |

But the elect. motor/gen. sounds ideal if the costs
could be competitive. AND if you are willing to sail for 173 days straight just to motor less than a day. (see prior post). |

Costs are going to get competitive over time
sure they are. in the 25th century, or by the 29th century for sure, if not by the year 4,000. Even when you include a small genset for the "diesel-electric" approach there's a big win in the long term "total cost of investment." *if* total cost of investment means total cost of investment the breakeven point may never be reached. but keep hoping and praying. |

They're getting competitive quickly. Another few years and
it'll make sense for most boats to go this way. Fossil fuels are a stupid solution. "JAXAshby" wrote in message ...

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. Excactly, as for 'honeycomb', I believe you're thinking of metal hydride storage, as is used for acetylene bottles, I think it's a well proven technology. Cheers Marty |
