Last time I looked they do NOT publish power consumption. KWH per bitcoin or KWH per GHS will tell you what their product is worth.

That's because when they did publish power consumption numbers they turned out to be off by several hundred percent. Until recently the published power consumption of BFL's entire SC line was 1w/Gh/s. They were allegedly so confident that this impressive level of efficiency would be met that they bet 1000BTCs that it would be achieved on shipping products, though the efficiency of the few products they have shipped has been measured to be approximately 6x 1w/Gh/s.

This means that they owe 1000BTCs to charity which they've thus far failed to pay.

We are so confident in our power consumption that we are offering up 1000 BTC to charity if we miss our power consumption targets by more than 10%. We are offering our devices at 1 watt consumed per gigahash. If our power targets end up consuming more than 1.1w of power per gigahash, we will donate 1000 BTC to charity! How is that for confidence in our power usage?

With the recent focus on power consumption, we want to reiterate that we stand behind our customers and our products. We have designed our mining equipment to be the smallest, fastest, most aesthetically pleasing and most power efficient mining device available on the planet. We guarantee that in the form of 1000 BTC! When you buy a BFL product, you know you're getting the absolute best mining device available, period.

Last month, we gave an extensive interview to Bitcoin Magazine where we shared many of the "secrets" and technical details everyone has been been waiting to see. In anticipation of the magazine's release, they've put out a couple teaser pictures of our Jalapeno and MiniRig boards.

More pictures are on the way!
