[填空题]Obtaining Drinking Water from Air Humidity
Not a plant to be seen, the desert ground is too dry. But the air contains water, and research scientists have found a _____ (51) of obtaining drinking water from air humidity. The system is based completely on renewable energy and is therefore autonomous.
Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water. But even here, where there are no lakes, rivers or groundwater, considerable quantities of water are stored in the air. In the Negev desert in Israel, for example, annual average relative air humidity is 64 percent — in every cubic meter of air there are 11.5 milliliters of water.
German research scientists have found a way of converting this air humidity autonomously into drinkable water. “The process we have developed is based exclusively on renewable energy sources _____ (52) thermal solar collectors and photovoltaic cells, _____ (53) makes this method completely energy-autonomous. It w
