Dear God, I just looked up the Project Ember II for the first time after reading this exchange. That thing is so offensive to the eyes that each one sold ought to come with a hand-written apology letter and a coupon for free ice cream. Seriously, it's enough to drive a man into therapy. It looks like a cheese grater and a robot from 1960's sci-fi had an abortion together.
But I guess what disturbs me most about it is that it appears to be a fully open design on all sides, which I'm sure is amazing for heat but terrible for things like dust accumulation and not shocking the ever-loving s**t out of your curious pets and three-year-old daughter. As funny as that might be under the right circumstances and on a really bad day, I'm not sure I could ever justify the apparent risk—unless someone can explain to me how this is somehow a thousand times safer than, say, sticking my hand inside of my PC's tower as I type this.
You'll get more of a shock from the dust in your hoover. The Ember works on 48v DC which is officially considered a safe voltage to touch. Not in the bathroom though.
Of course, sticking your tongue in might be interesting, but if you're into that, try a 12v battery first to give an idea of the danger.
