Even his son, Harrison, the 16-year-old test pilot, wasn't allowed to tell his friends that he'd been cruising around the yard back home in Christchurch, New Zealand in a revolutionary flying vehicle.

The only thing better than beer is more beer. And the only thing better than more beer is more beer you make yourself—it saves you a trip to the store. Thus, the NanoBrewMaster—an all-in-one, computer-controlled brewing system that takes your beer from wort boil to frosty pour. It’s the creation of PopSci staff photographer and resident crazy-project-builder John Carnett, who dreamt and built a first iteration of the device that we covered in the magazine last year.
