Green Options

Of all places to start a greenhouse, the Sahara Desert would likely rank pretty low for many. But someone is working on a plan to make food growing happen there. The Sahara Forest Project aims to use massive greenhouses to direct the sun’s rays for heat and energy, which is planned to regulate the air, filter water and create an environment for plant growth.

Solar power—is there anything it can’t do? British scientists have found a new use for solar technology with the Sahara Forest Project, a proposed plan to combine greenhouses that use seawater to grow crops with solar power installations.

The greenhouse-solar power combination could potentially provide food, fresh water and energy to deserts.

According to the project’s designers, the technology works by having greenhouses use solar farms to power seawater evaporators. Cool air is pumped through the greenhouses, reducing the temperature by about 15 C compared to outside.
