I was shown a miner designed by a company that designed "custom miners" that supposedly draws 0.100 Watts per 1GH/s and seems to be way more cost/efficient than the S7.  Several people have said it looks to good to be true.  Has anyone every heard of stuff like this or tried it?  A friend ordered one and is going to try it.  If it works I will let you know.

of course it is too good to be true,but there is no doubt that bitmain is making hell of profit on those manufactures...
can you pm me some details of it.

Which company is it?

Probably not valid. There has been at least one scam based on the specs of KnC's "solar" chips.

 .1W/GHs isn't even close to any of the announced but "not seen in public" 14/16nm chips, and is quite a bit better than any of the 28nm chips that have been seen or announced. Odd point for someone to be claiming....

possible but it will have a premium price!
so in the end it's not worth!

Interesting.  I'm glad everyone else here has confirmed what I have heard and that it sounds completely ridiculous.  I can't believe my friend is going to spend the money to see if this thing is real.  If it is, I will tell you what it is called - after I have cleared out their inventory  :).

So you are not going to tell us? :D Is it a preorder or has your friend hands on it?

I will tell you but if I put a link here now I'll never get a chance to buy one.  He is going to let me know if it works and I bet they will get some more orders if it does.  After that,  I will post it here.  Don't want to spoil it for him.

I would personally post before your friend invests a lot.  A "custom miner" with great stats sounds like a scam waiting to happen.

If he does invest make sure he sees the hardware work.  Not just renderings of the miner.

Don't post the link here. The miner is fake, the company is a scam, and your "friend" is most likely trying to con you out of your money.

I have to agree with OgNasty. If the company and it's product must remain "secret" for it to be viable, then it almost certainly is a fraud/scam/fake/whatever. Anybody with a legitimate product will open their product to some kind of scrutiny. Folks that want to operate in the "dark" do so for a reason, almost never a good one.

It's odd he brought it here.  As custom miners are really not something anymore.  During GPU day's is only time I can think of "custom miners".

You could order a GPU machine built to your specifics with X cards.  But in the day's of asics its really all mass produced with a few exceptions.

One possible scenario I can imagine: Just put some old dragon hashboards to one big enclosure,and you can easily have 4.2 TH miner. It sucks 4kW from wall but if buyer doesn't know that,who cares.

It would be kinda a jumble of wires with this.   And the weight of all those heatsinks would make it a hard sale on shipping.   I had the 1.5TH dragon that thing was the most heavy miner I have shipped yet it was around 45 or so pounds I believe.  In the 1.5 they put bigger heatsinks and it showed when I went to ship it to a buyer.

I think long ago there was a 3d printed custom one I had forgot about.  They took a few block erupters and put it in a case with RPI and made it seem like a special custom miner.   So I guess it has been done before, just not many times.   They charged a pretty penny back in the day for that one.

Thanks everyone.  I will make sure it is legit before I recommend it to anyone.  I won't propagate anyone else's scam.  Other people have also told me it sounds like a scam. The guy who ordered it also said it seems impossible.

Continuing my post: it doesn't matter if it is a scam(yes it is!) or not, the price will be to high to be worth investing.
Is like sp50: u have only 5kw available at home and say 10k in the bank......
