This video of the LifeSynthesis project in Norway (at the Lindum site) shows the testing of the Liquid Solar system which is integral with the SolaRoof technology. A thin liquid film is distributed over the inner film of the transparent building envelope (which has a Bubble Cavity of 1 meter). This liquid film is simply water and the flow forms “rivulets” moving over the plastic sheeting. One side of tunnel greenhouse has a liquid distribution pipe fitted with nozzles and the other has only holes drilled in the pipe. There no advantage to the use of nozzles and the simpler pipe with distribution holes to release the water at low pressure over the inner cover is best.
