1. A 24/7 hydro-electricity generation which directs the flow from the sea to the depression all year round;
2. When the sun rises from the east, a widest application of cheap perovskite solar cells is more than sufficient to pump the sea water back to the sea and the process continues 365 days in a year.Source:http://blog.sina.com.cn/s/blog_b96391280102y7ly.html

Death Valley is the location of the lowest land elevation in the United States. It is a north-south trending valley between the Amargosa Range on the east and the Panamint Range on the west. Death Valley is part of the Basin and Range Physiographic Province where north-south trending valleys are bounded on both sides by normal faults. The north and south ends of the valley are formed by the Sylvania Mountains and the Owlshead Mountains. The valley is one of the hottest locations in the United States. The record high temperature for the United States was measured there in 1913 at 134 °F (56.7 °C). Death Valley gets very little rain and the deepest part of the valley is generally dry. However, heavy rains can cause flash floods that produce a large lake in the bottom of the valley.
The Salton Trough is the second lowest depression in the United States. The lowest land in the Salton Trough is along the shoreline of the Salton Sea. The lake level is approximately 69 meters below sea level; however, the lake rises and falls in response to runoff from the New, Whitewater and Alamo Rivers plus some agricultural runoff. The bottom of the Salton Sea is about two meters higher than the bottom of Death Valley.
