They run slower than 3600 RPM because they use a belt drive system to
increase the RPM from the Kubota running its favorite speed of 2800 RPM.

Having owned, now, two Honda electronic gensets, I think it's way past
time someone engineered a marine electronic generator set that operates
the same way. The frequency of these Next generators are still
dependent on engine speed, though slower. The electronic generators,
this is not so. The small electronic generators get their power from
tiny packages by running FASTER than the speed of directly coupled
gensets. The larger models in metal cases like my EU3000is run much
slower than those speeds, making them much quieter in operation, the
computer speeding them up only during heavy loads. A marine model would
operate similarly, saving noise and, much more importantly now, fuel.

A very slow turning diesel electronic genset would be very quiet,
indeed. It would also be tiny in comparison to the old 60 Hz monsters
because the actual alternator is a very high frequency, multiphase unit
that looks exactly like the magnets mounted on the flywheel with an
internal stator on an outboard motor. High voltage alternators keep
down the huge coils used to create 60 Hz on huge cores necessary to go
so low in frequency. That's no longer necessary, with the advances in
electronic power generation.

Next generators are nice, but still old tractor technology in a small
package. It's time to move on into the 21st Century, even for
sailboats.


Yanmar now makes a KMG65E generator that fits between the 3 and 4
cylinder engines (J type, I think) and gearbox and output 230 VAC @ 13
amps continuous.

I believe they are the type you describe above as the "generator"
output feeds a Box of some sort that in turn feeds the mains. There is
an external control head that seems to turn things on and off.

I think the 21st century has arrived, at least in Japan.

Hi, again,

And how much do these beauties cost? ...

.... Our hosts ashore are generously offering us the use of one of
their cars. The current vehicle (pardon the expression) is a Ford
Hybrid.

When it's time to repower Flying Pig, I sincerely hope the technology
and the powerplants have caught up to the marine world, because, the
regenerative braking aside, I can see this technology in our boat,
very comfortably.

It's way OT, so I'll not go into it, but research how power is
delivered to the wheels and stored and generated. Seriously cool.
It's a gas (again, pardon the expression) to take an empty SUV to the
pump and *almost* squeeze in 12 gallons...

Meanwhile, the genset we took out was _under 800 hours_ (that's how
serious it was), and we've not missed the AC - or, at least, not
enough to regret regaining the storage and simplicity, even if we
wouldn't have needed the genset - even at the dock in August in
Charleston. At anchor, we sleep under blankets or, if unusually warm,
sheets. Assuming we ever get to somewhere with a reliable breeze,
we'll definitely - instead of nearly always - be just fine. It's the
dock queens that need the AC...

Oh, and, this summer, we'll start in Maine in either late June or
early July. With the 50* water around us, I have no doubt that, even
with the sometimes-blistering sun for 19 or so hours, we'll be under
blankets at night. Then we'll move south, staying in the warm, but
not hot, environment, getting to the Keys by fall (October-ish) before
we make the jump to the EC, likely never to sail back until it's time
to sell.

Back to the genset/hybrid concept, however, I readily accept the
possibilities for a very small powerplant with an accompanying very
large storage system, and a completely 110VAC boat. Simplifies a lot
of stuff, and despite the many systems we have aboard, I'm a big fan
of simple. In the meantime, our power generation and storage system
seems to be doing very well.

Yes, the multiphase, high voltage, high frequency AC is simply rectified to
DC, then fed to a large switching power supply which, in turn, converts the
DC to a rather nice-looking, synthesized sine wave at perfectly 60 Hz and
120VAC so rock solid it is certified for computers. Variations in the load
from no load to full load don't vary the output perceptably at all from the
intense digital regulation.

My 3000is Honda is electric starting, but not intended to be remoteable
because it has a simple manual choke. I found some plans to remote control
it by installing a choke solenoid off an outboard motor into it, replacing
the manual choke knob with a pushbutton for local control. It was a 3 hour
job. I now have a control panel below the air conditioners in the
starboard bulkhead to control the EU3000is from inside the van. Honda got
the message with the new EU6500is 6.5KW, electronic genset. It has a
plugin remote control and computerized enrichment system with no choke just
like my 250cc, 1 cyl Honda Reflex scooter does. It simply starts at a
touch, cold or hot.

I don't know what the current prices of Next Gen's sets are. Ask them.

As to hybrid vehicles, the cost of gas isn't the only consideration.
They have much higher maintenance costs because you MUST go back to the
dealer for service, and even then lots of dealers have no electrical
engineer aboard to fix them, so they start parts swapping and praying on
the prayer rugs installed in each bay of the service department. Any
car part only available from a dealer marked "MODULE" is, of course,
prohibitively expensive as if it were made of Rhodium ($9400/oz today).
Every module, of course, that didn't solve the problem must still be
added to the bill, as usual. A hybrid is fine until it's broken.....out
of warranty. Then, it becomes a terrible burden far outstripping any
gas mileage increase. I want a car any bubba in a service station can
fix. You've been in mine...(c;

Drive by a Ford dealer's parts department and price a new battery pack
after the warranty has run out.....(c; These long battery pack
warranties hybrid manufacturers are eating are the only way to disguise
the replacement cost. (Hint - It's NOT $89.95)

The other note is resale value. The hybrids might as well be disposable
because, once out of warranty, with a battery pack that needs replacing
that's 4 years old, no fool in his right mind wants it. The hybrid
manufacturers keep coming out with "improved" models, rendering your
hybrid "old and obsolete" like no other vehicle ever produced since they
installed gearshift sticks to get the clutch pedals off the floor.

Add up all these costs.....even today, gas is cheaper.

Not to worry, FINALLY the oil company politicians are going to allow the
Smart Cars to come in from Europe.....well, only the least fuel
efficient ones. What America needs is a good 2-cylinder diesel city car
with 2 seats in it like a Smart Car. Don't hold your breath.
