Dear MEL
Topic Readers,
Growing
food with seawater and solar power
Tomatoes
grown without soil or fresh water? That’s what exactly a new venture farm is
doing in a desert region in southern Australia.
They are
growing 15,000 tons of tomatoes a year using desalinated sea water in hydroponic
greenhouses. The both desalination and heating-cooling systems are powered by
solar energy. Sounds very green to grow red tomatoes,
doesn’t it?
Though
initial investment for this farming model is substantial, the running cost is
significantly lower than conventional farming. This solar-powered hydroculture
model seems economically and environmentally advantageous in places where there
isn’t enough freshwater to grow vegetables, but not so for staple crops such as
rice or wheat that require open and huge space to grow.
Enjoy reading about this new hydroculture
model and think where to build this solar-powered hydro-greenhouses, what to
grow there and how to finance it.
