When I use to travel to Austin, Texas a couple years ago, going north
on I-71, there was a place that I think is some kinda outside lab site
for a local college which has solar panels and a small structure with
grass growing on the roof. I never stopped there but thought it was
interesting what they are trying to do. Do you have to eventually mow
the roof grin ?


in switzerland they grow plants on the roofs, but they let the cows mow
them down.
