If you ask me (even though you didn't), the way to go would be to have a CVT for getting up to speed, and then be able to switch it in to a fixed gear once up to speed.

I also assume the reason belt driven CVTs are only 80% efficient is slippage, which is the main reason friction belts are less efficient than chains, and why a timing belt is not. The other losses come from flexing/compressing/decompressing the rubber.
