As I have said before the power estimates are simply unrealistic. FPGA hard copies are far less efficient than pure silicon designs. So imagining that easic will deliver at a lower power consumption than KNC is in the territory of elves and unicorns.
The boards and all of the components involved are really not that expensive. It might add $0.15-$0.25/GH to the total cost. I agree that the power estimates should be higher than KnC, I never said it would be lower. KnC gets between 0.8W/GH - 1.5W/GH We'll probably see 1.2-2W/GH with the FPGA copies.
Regardless, even if the gear was $2/GH cost, gear in hand right now is selling for ~$20/GH (Note I didn't say this would make a profit but it is selling and ActM does sell hardware)
At $2/GH mining will be very profitable for quite a long time at current prices. Arguing against this means you do not have a firm grasp on what will be delivered and when. I call it the sky is falling syndrome.
Wrong. Go price voltage regulators with reasonable power conversion efficiency. Those alone will blow your estimates apart.
Please show us the math, the newbs need saving. Back it up like you are asking everyone else to.
