There are not many other methods more efficient at transferring power than a chain. Chains are more efficient than gears and shafts.

The reason shafts and gears are employed is to reduce maintenance, not to increase efficiency.

I'd be curious to know what other methods of energy transfer are more efficient than a chain.
