i suspect what they're calling e-paper is something like the Sharp memory LCDs that Pebble smartwatches used, not the E-Ink that Kindles have. still very battery efficient; most of the power consumption from LCDs is in the backlight, not the actual display layer

it also could be totally fake and not look like the videos at all
edit: yeah the hackernews comments from the founder imply it is their own custom implementation of a reflective lcd made to look like e-ink
