A local team in Thailand have profitably reused thousands of old flip-flops, turning them into new shoes. They call their project “Tlejourn,” a Thai play on words for traveling shoes.
Because flip-flops can’t be melted down and recycled, they devised a low-tech, inexpensive way to upcycle old flip-flops by grinding them into small pieces and then gluing them together into one solid piece. The volunteer group Trash Hero gives them all the flip-flops they find while cleaning up the local beach.
Bringing Electricity to Disaster Zones Zéphyr is a photovoltaic balloon and eco-friendly generator created by Karen Assaraf, Julie Dautel, and Cédric Tomissi. The balloon only requires water in order to inflate and can capture solar energy from as high as 165 feet (50 meters) in the air. The balloon is connected by a cable to a base, where the energy is stored. Its creators hope that it will bring power to areas struck by natural disasters
