Uses for concrete

[bpdlr]

I was just looking around for shiny things to steal from the fancy homes (using the pick up tool) and was wondering whether I could pick up a fireplace - probably not, but that got me thinking, there's no use for all those rocks I forage, and concrete powder exists... why not be able to build a fireplace at high levels of Carpentry?

 

Also, while on the subject: you can build a home-made refrigerator using concrete, basically it's a concrete box built outside with a rig setup to drip water onto the exterior. As the water evaporates, it cools the interior of the box. Obviously would work well in the hot summers!

 

That's another thing - garden hose. Would be a great addition.
