Professor Bo Zhao of the University of Houston has reported on the development of a new form of solar energy collection technology called thermophotovoltaics (STPV) which has achieved record-breaking efficiency levels.
[pdf] Graphene batteries offer high energy density and fast charging capabilities, making them ideal for portable electronics and electric vehicles. Flow batteries provide scalable, long-duration energy storage suitable for grid applications due to their ability to independently scale power and capacity.
