Hi tsubaki,
I'm always messing around with things started but usually unfinished, too many diy plans that have accumulated for a bunch of years.

The heat and skeeters have pretty much trapped me indoors, but I have a work in progress that involves compressed air/electric and battery storage.
Things look good so far.

there is loss in the gen itself if you feel the gen while running it will be hot and heat is lost energy. there are lots of variables in efficiency. i will try and find an old link that may help. From what i remember there gens were 98% eff. so you would have 2% loss across the generator but most gen are not that eff.

this is not the site i wanted but it may help. if i can find were i saved info from the ossa powerlight sight i will send it there info is easier to understand and in more depth than bentleys. http://www.bentley-marine.com/Technology.htm http://www.bentley-marine.com/AEPS.htm

The Bentley site has some interesting products, I noticed a rating of 98% on the gear box and 96% on at least one of the motors.
The mention of a generator head 10" X 10" X 22" is the same size as mine.

You mentioned heat on the generator, now here is part of my mental blockage, If you consider bearing and air friction, they will produce some of that heat and the loss is not affecting the generator, it is accounted to the power that the prime mover provides.
The iron and copper losses are a product of motion induced by the prime mover, would they not fall into the same category as the bearings and air ?

Now the electric motor taking electric energy from some source is inducing it's own rotation, in this case the four sources of resistance are a loss that is taken out of the power delivered by the motor. This is to me what makes the 96% efficiency claimed by Bentley, a little bit suspect.????
