Dalhousie research team develops water purification device from used tires
Researchers at Dalhousie University have developed a new device made from old tires that uses solar energy to purify water. The device, a floating solar still, can produce over 3.5 liters of clean drinking water per day at a cost of just 86 cents per liter, while also generating a small amount of electricity. The team made the key component from discarded tires by grinding them into crumbs, heating them to 500°C to create carbon particles (char), and then combining the char with titanium dioxide powder to form titanium carbide nanoparticles.
