As said earlier, LN2 generators are very real, they are used in labs and whatnot. The size though is what bugs me with this apparent product.

If anyone is interested, I did a post on reddit a while ago about the weird parts of what they are saying as well as a response to their later letter:

What if the images make the device look small but it really is that big?

2800W total...  BFL does 5 GH/s for about 30W, so 1000 GH/s would require 6kW.  That leaves -4.2kW to condense enough nitrogen to cool it.  Checks out!

Everyone knows thats how you cool things, put the energy being saved backwards through a heating element and then the liquid nitrogen, being so low temperature, turns the main ASIC into a superconductor negating loads of power draw. That's how it's really done. Wink

I have to see it to believe it.  I don't really believe in news reports now.

Let's all agree this is a super SCAM, but let's say I have access to unlimited liquid Nitrogen (I do). How much of a performance gain on my Butterfly Single SC could be achieved by cooling the chips down to 100K? What are the concerns for the electronics?
-De-humidified chamber (reduce condensation on the electronics)
-Nitrogen Gas venting (reduce asphyxiation of the operator)
-Do you need to you need stabilize the board from vibrations? (I imagine normal room vibrations might crack the board or chips over sustained time at supercooled temperatures.

Imagining I can actually build a stable super-cooled setup... what are the potential performance gains?

Just look into cpu overclocking. You're still limited by locked clocks and unstable vrm. But I'm guessing 50% gain.
