Botanical Gardens ~ Delightfully Engineered Ecosystems

While thinking about the design for a new apartment complex near MIT straddling a cogeneration power-plant, I thought why not use the vented steam & otherwise waste heat to incubate a botanical garden, such as this lovely example in Washington DC... A botanical garden would bring tremendous benefits, most certainly aesthetics and waste recycling, but also it could be a function space or a restaurant area and certainly a natural asset, a repository of exotic flora.
