Let's assume SON came out with a 1.5W hub. With an efficiency of 60% one would need 2.5W. Thats roughly 4W less than the standard SON requires. Any bad lubricated or dirty chain or loose clothing causes much more drag. I personally do not consider this important and i don't think SON will come up with such a hub, i guess they rather make a more powerful one for off-grid use.
