How the Humble Lamp-Post Could Help Power our Cities…
“Cement mixtures made from power station waste could turn buildings in to batteries, for example. These potassium-geopolymetric (KGP) composites are cheaper than ordinary cement and can store electricity. A six-metre tall lamp-post made from KGP and equipped with a small solar panel could hold enough energy to power itself throughout the evening, researchers say.”
“We have shown that KGP cement mixtures can be used to store and deliver electrical energy without the need for expensive or hazardous additives,” says Lancaster University professor Mohamed Saafi, who is heading up the research.”
