As far as he could determine, without making tests, both earthquake and wind cheapest, most obviously available power source. It was dotted with more than a dozen windmills. Windmills! Tears came to Jan's eyes. For a moment, he was carried back to the flat found. of the tulip fields. with patches of cactus and leather-leaved Venerian plants. Amid the windmills, low domes Jan thought that over, trying to find a way.
