Thermal Towers in Namibia: Energy and Food

Namibia is examining the feasibility of using solar thermal towers.

Thermal towers work by creating an airflow that spins turbines and the bigger they are the more efficient they become. Namibia appears to be a great place for thermal towers due to the amount of sun it gets. The proposed thermal towers in Namibia will also act as greenhouses for growing food.

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each – enough to power Windhoek, the nation’s capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.
