First public lighting system that runs on solar and wind energy
Scientists have developed the first autonomous industrialized public lighting system that works with solar and wind energy.
Cooling the air with sunlight
A firm has developed an evaporative cooler that has an integrated photovoltaic system isolated from the electrical network, which enables to refresh an area of ??approximately 200 square meters.

Two-stage power management system boosts energy-harvesting efficiency
A two-stage power management and storage system could dramatically improve the efficiency of triboelectric generators that harvest energy from irregular human motion such as walking, running or finger tapping.
Shifting winds: An early warning for reduced energy
Chinook winds can precede large shifts in wind power output from wind farms — a challenge for companies seeking to provide a constant stream of green energy to consumers. By establishing a connection between local meteorological events and power grid output, the researchers hope that they may ultimately help grid operators more accurately predict fluctuations in flow and manage the grid accordingly.
Discovery about new battery overturns decades of false assumptions
New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery — a discovery that could pose a challenge and more sustainable, less costly alternative to the widely used lithium-ion battery.

Smart anti-icing system for rotor blades
In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient heating system frees these turbines from the ice in a matter of seconds. It is only switched on when water freezes.
