When attacked for all our big talk about living in harmony with the environment despite obviously lacking any cultivated green space to allow ourselves to be somewhat self-sustaining, we’ve often sworn that we wouldn’t start an urban farm until we could maintain it with robot-mounted lasers–sort of our version of “when pigs fly,” if you will. Well, we are apparently almost there, as FunnyCrave’s listicle of 9 Sci-Fi Gardening Tools features both a laser mower and several robot mowers. Several are promising, but others, like the one below, don’t seem capable of wielding lasers.
