If we don't change direction, these blackouts will only multiply

Opinion: The large power outage we experienced at the beginning of the month may be a preview of what is to come for the Israeli electricity sector with the increase in the frequency of heat waves due to the worsening of the climate crisis. The solutions are in our hands, now

spiritual desalination

A new Israeli invention makes it possible to dewater water with the help of a unique wind turbine whose axis of rotation is vertical, which operates without any use of electricity. This is to deal with the problem of the enormous energy consumption of the desalination process,

Without wind and with bells: the drone that will keep bats away from wind turbines

Researchers from Tel Aviv University and Haifa University tested the effectiveness of a dedicated device mounted on a drone, designed to keep bats away from the wind turbines that kill them en masse, and allow the turbines to operate efficiently and continuously

It is not enough to make a spirit

A wind turbine farm established in an arid area in Kenya could have been a success story, promoting the local residents, who are disconnected from the electricity grid. However, the electricity was channeled to the big cities - and the residents were skipped

The green buildings of the future

In the competition organized by the European Union, prizes were awarded to exceptional green construction projects, in the spirit of the principles of the Bauhaus style. When will we see such buildings in Israel as well?
