PV outperforms wind, piezoelectric energy in street lighting
Scientists in Thailand have assessed which technology between PV, wind, or piezoelectric energy is better for powering street lighting and have found solar is the winning tech, as it proved both economically and technologically feasible.
UK scientists build PV redox flow battery with 9.54% solar-to-chemical efficiency
The PV-driven redox flow battery can reportedly achieve a maximum solar-to-output electricity efficiency of 3.11% during a 36-hour period. The system incorporates a 25 cm2 heterojunction photovoltaic device and is based on a neutral pH aqueous iodine-bromine redox couple.
PV-driven thermic solar geyser for domestic water heating
Scientists in India have built a solar-powered thermic solar geyser prototype based on a nichrome wire heating rod and a flexible pipe heat exchanger with aluminum fins. The system is designed to generate domestic how water and can reportedly achieve a levelized cost of energy of $0.051 per kWh.
Polar Night Energy to build second sand battery pilot in Finland
