Technology: Parabolic Troughs

17

Technology: Fresnel, dishes, towerFresnel Concentrators•BMU sponsered development program•Lower material costs but also lower efficiency

Parabolic Dish with Stirling Engine•Highest efficiencies (close to 30%)•Suitable for decentralized small scale electrification in remote areas

Power Tower•Interesting technology due to high efficienyies and thermal storage•More R&D needed

Solar Chimney

Solar chimneys work on global irradiation and do not need cooling water.However only a small scale pilot plant was built.
