Extraterrestrial liquid water not. Similar indirect evidence, however, supports the existence of liquids below the surface of several moons and dwarf planets elsewhere in the Solar System. Some are speculated to be large extraterrestrial "oceans". Liquid water is thought to be common in other planetary systems, despite the lack of conclusive evidence, and there is a growing list of extrasolar candidates for liquid water. As of December 2015, the confirmed liquid water in the Solar System outside Earth is 25-50 times the volume of Earth's water (1.3 billion cubic kilometers). Water on Mars exists today almost exclusively as ice, with a small amount
Silicor Materials bricks, cut those bricks into wafers using wire saws and convert the wafers into solar cells. These cells are then assembled into conventional aluminum-framed, glass-encapsulated solar modules (also known as solar panels) for use in distributed and centralized solar applications. In contrast to the Siemens Process, which requires a total of four phase changes—solid to liquid, liquid to gas, gas to liquid, liquid to solid—Silicor's silicon only goes through two phase changes- solid to liquid and liquid to solid. This change reduces the manufacturing energy requirements to an estimated total usage of 10 to 25 kWh/kg. Silicor's method does not
