Hypoid gear I guess is one having issues, 85-90% efficiency I believe?

With belts you would not need that as you can do differential effect by changing ratio of belt pulleys.

Then you have to add up all the gears which makes that 15-25% drivetrain loss, where with belts you probably could get away with less?

Not quite sure about this of course, but it is something that I have been thinking and which might give something, but it would require rather good facilities to actually make such gearing.
