Like your typical garden flower, this tulip captures heat from the sun for energy. But unlike most flowers, this one is 115 feet tall and uses a combination of gas and mirrored heliostats to spin a gas turbine that creates electricity.

AORA‘s concentrated solar power (CSP) systems – designed in southern Israel where sunlight is abundant and water is scarce – uses pressurized air, rather than water, to spin a conventional gas turbine. If the air momentarily cools, from cloud cover for example, the tower automatically reroutes the air through a combustion chamber that can use anything from biogas and methane to natural gas and diesel to heat the air and spin the turbine.
