This comment from one of the original consulting engineers is really interesting:

"Bio-Med Engineer Langhorne PA 13 hours ago I worked in an engineering design consultancy that was contracted early on to help productize the ZPM design, and as such am intimately familiar with their initial concepts. In my opinion, the founders were initially earnest and dedicated but also naive and lacking in engineering judgement. They confused the ability to raise money with the ability to make sound engineering and technical decisions. Falling in love with one's ideas is a trap into which many inventors fall, and ZPM fell hard.

Additionally, I believe that ZPM received a lot of questionable advice from people who did not have their best interests at heart, and were swayed by strong personalities.

But the early backers - particularly the engineers - should have had the sense to realize that open-source firmware that is intended to control a consumer product that delivers scalding hot water is a fundamentally BAD idea, and that using a PID loop to manage the process is totally unnecessary.

What this article highlights is that Mr. Polyakov's talent is in raising money and expectations. It is unfortunate that neither his ethics, nor his engineering abilities can match those talents."
