On my walk I encountered this "Learning Barge"

Mr. Google provided this--
Powered by sun and wind and equipped with live wetlands, an enclosed classroom, composting toilets and a rainwater filtration system, the 120 by 32 foot Learning Barge is designed to both model and teach ecology and sustainability to the next generation of lower Chesapeake Bay stewards.
De la Blip is hopeful that the neglect and pollution of our Elizabeth River will be a thing of the past!
