The target user of this little miner isn't looking for 100W+ miners, they can buy one new from antminer. Furthermore 22Ghs/W is in the (distant) future because there is little to no information on the newer chips making 3rd party miners impossible. As I said in the opening post; these are not meant to be run on a normal pool, but can be used to solo mine (with a chance of ~1:25000 of finding a block per year) giving a better chance of a substantial prize than a lottery ticket. And you will learn a few things running such a small miner, such as what big numbers really mean, how pools work, how to run a miner at peak efficiency, how to cool electronics etc.
