The hydroleaf, from designer Mostafa Bonakdar, collects both solar energy and rain water. The concept behind the design allows it to use the solar energy to power a purification system, making the rainwater drinkable.
The device features a large canopy mounted on top of a pole, which funnels water down into the purification system. But the canopy is also covered in photovoltaic solar panels, providing the power. So it’s a nicely self-contained system. The creator envisions the hydroleaf being used as a public shelter, providing a nice seating area for those waiting for a bus. You can get out of the rain and grab a fresh drink of water as well.
