Flexible Solar Cell Technology Lights Up Bus Shelter

New flexible solar cell technology, developed by engineering researchers at McMaster University of Hamilton, Ontario, has been installed in a campus bus shelter to provide power lighting for night-time transit users. The ability to bend the solar cells to fit the curved roof of the bus shelter is one of the main features of the technology.

Yb14MnSb11 as a High- Efficiency Thermoelectric Material

NASA’s Jet Propulsion Laboratory has found Yb14MnSb11 to be well-suited for use as a p-type thermoelectric material. The figure of merit that characterizes the thermal-to-electric power-conversion efficiency is greater for this material than for SiGe, which, until now, has been regarded as the state-of-the art high-temperature p-type thermoelectric material.

Utilizing Ocean Thermal Energy in a Submarine Robot

A proposed system would exploit the ocean thermal gradient for recharging the batteries in a battery-powered unmanned underwater vehicle (UUV) of a type that has been deployed in large numbers to research global warming. A UUV of this type travels between the ocean surface and depths, measuring temperature and salinity.

Alternative OTEC Scheme for a Submarine Robot

An alternative system for exploiting the ocean thermal gradient to generate power would be based on the thawing-expansion/freezing-contraction behavior of a wax, or perhaps another suitable phase-change material. The power generated by this system would be used to recharge the batteries in a battery-powered unmanned underwater vehicle.
