Powerhouses: nanotechnology turns bricks into batteries

Research could pave way for cheap supercapacitor storage of renewable energy The humble house brick has been turned into a battery that can store electricity, raising the possibility that buildings could one day become literal powerhouses. The new technology exploits the porous nature of fired red bricks by filling the pores with tiny nanofibres of a conducting plastic that can store charge. The first bricks store enough electricity to power small lights. But if their capacity can be increased, they may become a low-cost alternative to the lithium-ion batteries currently used.
