Call it “fuel without fossils”: Jonathan Trent is working on a plan to grow new biofuel by farming micro-algae in floating offshore pods that eat wastewater from cities. Hear his team’s bold vision for Project OMEGA (Offshore Membrane Enclosures for Growing Algae) and how it might power the future.

You don’t need to eat fish to set up a backyard aquaponics system! Ducks are a great alternative and produce a huge amount of nutrient for growing veggies (not to mention eggs, meat and snail & slug control!) and they’re generally good friends to have around. At the Farm of Fluff, Chris and James set up this “quaquaponics” system with a few bits and pieces we’d collected from the side of the road and so far it’s doing brilliantly! You need a strong pump and good filtration to cope with the large particles coming through, though! (We found a whole tomato blocking the drain one day, so check and clean regularly!)
