Hollywood actor and environmentalist Leonardo DiCaprio uses his instagram account to spotlight environmental challenges facing the world and environmental breakthroughs.

As such, his 13.8 million followers were sent a photo of Megalim Solar Power’s Ashalim power station now being built in the Negev desert.

“The arid landscape of Israel’s Negev Desert will look like a futuristic movie in the near future. The country is building the tallest solar thermal tower in the world above its dusty sands,” writes DiCaprio on his post alongside the photo.

The Ashalim project will comprise 55,000 mirrors which will feed solar heat into a 240-meter-tall solar tower — believed to be the highest in the world.

“The tower should be able to produce enough power for about 5% of Israel’s population when it’s concluded,” writes DiCaprio. “The sunlight will be reflected by the mirrors to a boiler at the top of the tower. The boiler will then be able to convert them and heat water to steam to turn the turbine in a conventional power plant.”

The Ashalim power station, scheduled to be up and running by the end of the year, will combine three types of energy: solar thermal, photovoltaic and natural gas.
