Professor Bob Bradley and his company Matsurf Technology UK Ltd. has recently published in the Journal of Advanced Functional Materials work on a new solar powered desalination unit. The device, which is free-floating, uses a solar-capture layer produced from a biowaste derived mesoporous carbon (BMC) supported on a capillary geopolymer and has one of the highest saline to steam conversion rates ever reported (7.55 kg m−2 h−1).
