Friends of NELHA, the non-profit arm of the Natural Energy Laboratory of Hawaii demonstrates the DewPoint System wine grape display which uses only seawater to grow wine grapes. This is the only place in the world where such cold seawater agriculture is demonstrated. Wine grapes are growing extremely well considering it receives no water source other than the cold condensate that forms on the seawater pipes. In addition, the vines give 3 full crops of grapes each year because "seasons" are artificially created by turning the seawater on and off to simulate summer and spring.
