I have a question about SP30. As i read in the product information you will have a chip that can pump 300GH/s. How do you plan to cool it? Looking at your competition KnC has a chip that can do ~170 GH/s and they have a big ass radiator for every chip. HashFast has a chip that can pump 750GH/s and it is water cooled. Bitmine.ch has a chip that does ~25GH/s and they need a big ass radiator too. Your case for SP30 makes me think that you will have the same construction as SP10, but somehow it doesn't feel right. Could you please explain a bit?
The answer there would appear to be that they expect significantly greater power efficiency. Normally I would recommend extreme caution: Getting power estimates vastly off appears to be par for mining hardware companies but in this case they apparently have a first chip in operation.
