i have not gone through the old hard drive yet and not sure if these photos are a good fit....
this building is now completely restored and is now office space
it was the crematorium of the old hospital in peterborough ontario
it was in an abandoned state for a long time (other than pigeons)
it had leaks in the roof which over time let to stalactites hanging from the ceiling
it even had tunnels which led to the hospital and another building nearby which i explored
the house on the water is abandoned and i have pictures from walking through but they are on the other hard drive
i copied the preview images and it made the file size bigger than necessary so next time i will copy the images themselves as i did not make note of the file names this time
another thing with that is you could make the collector bigger than the grow space in a situation where the sun is obscured so as to have full light in a dimmed world in the case of a large volcanic eruption/impact/explosion
this could maybe be its own topic but related to what Mart Hale brought up...
i remember reading or watching a video on greenhouses in very cold climates and the one person said dont even bother with a greenhouse just grow with lights 20 feet underground
i was thinking it would be cool to have a space 20 feet underground and a parabolic reflector and have fiber optic cables at the focal point which bring the light down to the underground space
the reflector could be set up to track the sun like greenpowerscience had his solar cooker track the sun

the rouge national park has been buying farms to add to the park and so many houses sit empty
i have been taking pics of the stonemasonry on some of them and i have one to share and a drive by pic of a barn falling apart
i have some pics of stonemasonry in structures which are still used which might be better in another thread ?
i also have lots of pics of old delapitated buildings but on another hard drive and would require some digging to find
