I like the potential. I too have a stainless conical and there are ports in the lid that could allow an antenna or maybe allow some signal to escape the Faraday cage that the vessel represents. Considering this is a modestly costly device, you would have to consider that the brewer that is interested in this unit is likely to have this sort of vessel. And almost any brewer strives for a temperature controlled fermenting environment, so a chest freezer or refrigerator is almost a given.
I'm also curious how the unit is sterilized and if there is any need for it to stand up or be oriented in the vessel? A conical obviously does not have a flat bottom. I'd be interested in understanding how it is obtaining the gravity readings.
just like the name suggests, there is a little bug in there with a mic and transmitter. It takes a little sample. tastes it and says 'Too Sweet!' into the mic. similarly for temp readings it sticks a little thermo out the tiny window and says into the mic 'Do you believe this heat?'
