Extraterrestrial liquid water extrasolar planetary systems appear to have very different compositions to the Solar System, though there is probably sample bias arising from the detection methods. Liquid water has a distinct absorption spectroscopy signature compared to other states of water due to the state of its hydrogen bonds. Despite the confirmation of extraterrestrial water vapor and ice, however, the spectral signature of liquid water is yet to be confirmed outside of Earth. The signatures of surface water on terrestrial planets may be undetectable through thick atmospheres across the vast distances of space using current technology. Seasonal flows on warm Martian slopes, though
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
