Jim,
We just used Trace Engineering's classroom for Solar Energy
International's Photovoltaic Design and Installation workshop. So
I've been hanging around inverter engineer's for a week, and I start
to get a little bit of what they are doing.
Their sine wave inverters are slightly less efficient than their
modified square wave (marketing calls them modified sine wave)
inverters, but NOT 60%. The efficiency curve on the SW4024 never
goes below 85%.
The modified square wave inverters are somewhat better, as I recall,
but an interesting note is that even the (most) loads that run on
the modified square run more efficiently - cooler, quieter, more
powerfully - on the sine wave. The efficiency curves don't measure
this change in performance.
We've been running a Trace 2024 modified square for about 12 years
now. It's a great machine! We've thrown lots at it and it keeps on
going. The only thing that had trouble with it is our copier.
There's a handful of loads that don't like modified square, but most
can eat it fine.
I wish you could have been there for the full tour of Trace's plant!
You would have understood more than I did. These people make high
quality stuff. They weren't happy with the transformers they could
buy, so they make their own.
Take care,
                        Ian

I agree. We've been running a DC and AC household off-grid for 15
years. If I started again, I might go mostly AC, and I'd certainly
recommend it to non-tinkerers. I still like DC though - no
conversion losses, no EMF, more efficient motors.
But I'd still recommend running major loads like fridge and freezer
directly on DC.
Great advice!

That's not much time!
One of the funnest projects is to get a small solar panel and a
small DC pump. Hook the pump to the panel and put the pump in a
bucket of water. Then play with how much water it pumps in different
light conditions.
Try Edmund Scientific for equipment (800-728-6999), or find a local
renewable energy dealer to help you. Where are you? I'll recommend
someone if I know someone in your area.
Have fun,

Write your reply.

assistant: Most of the recent large ships are diesel-electric.  Works great since
it allows the diesel to run at constent RPM, you derive ships power
from the same engine ( no need for another engine for the genset ),
infinite control over the speed and torque delivered to the props,
when cruising, you can usually shut one engine down and run both props
from the other engine ( makes periodic maintenence a lot easier too )
One added advantage is that since the engine isn't delivering power
directly to the prop, the engine/generator assembly can be floated on
shock absorbers - the vibration and noise is significantly less.
The technology has been in place in locomotives for 20 years - it took
a while to show up on ships but it is proving to save fuel, offer
better control and be easier to run.
Check any of the commercial marine magazines - Professional Mariner is
a good place to start - National Fisherman is another one although it
covers more of the small boats ( too small for these systems to be
economical )
