00:03you've probably seen something like this before a drone that can fly over a fertile area and drop
00:08seeds from the sky but this project being led by researchers at carnegie mellon university takes
00:13the sky seeding method even further this is what its developers call a self-burying payload carrier
00:19a way to more easily quickly and more cheaply plant in the future they designed the seed carrier
00:24after the erodium plant which has seeds that unfurl and corkscrew into the ground when they get wet
00:29this is professor lining now to explain the r d process behind the new plantable on the material
00:34side we eventually chose wood because it is a abandoned biodegradable material it's also very
00:40stiff in order to have a self-burying carrier to drill into the ground it has to be really stiff
00:47more importantly wood is a hygromorphic material meaning it can respond to the rain and self-morph
00:53you know as they went with a three-tailed design as it creates perfect angles for the drilling to
00:58occur after the material begins to corkscrew but the payload carrier can do more than just help seeds
01:03get into the ground it can also carry organic fertilizers pesticidal nematodes or even sensors
01:08the aerial planting method using their payload carriers resulted in 61 of all seeds dropped entering
01:15germination after just 15 days
