We have a good guess. They claim their 3.5 GH/s chip is USB powered. So there you go. 1400 MH/watt (or better), which means if the 1 TH/s Rig is using the same chips in parallel, 714 watts. And thats assuming they are using the exact same components in each product, which makes no sense (why produce special cases when you can just offer bulk discounts).
That's why only an idiot would give them money in advance for a product which has no proof of concept (or even proof of development starting). Their numbers are pulled out of their ass.
An IDIOT like a fox. HAHA
