Other applications of Helium filled 'half-spherical' balloon
It is complicated and unsafe to lift lighting equipment over a construction site.
Trimming out weight is applied to make the lighting better and easier. It is determined to lift only the 'necessary' lighting equipment (a reflector/balloon) leaving the floodlights on the ground. Site illumination is adjusted by controlling the number of floodlights and the reflector position. This system is more convenient and safer to use.
Other applications of Helium filled 'inverted truncated pyramid'
Concentrated solar system : Patent WO200930037 2013 QUADRA SOLAR)
There is provided a concentrating solar collector in the shape of an inverted truncated pyramid (collector) with light reflective surfaces on the inside.The collector includes a large top opening which is pointed towards the sun
collecting the sun rays.A high-concentration photovoltaic solar cell is placed at the narrow end of the collector.The light is concentrated onto the solar cell, which generates electricity from the concentrated solar light.The collector is
made of, but not limited to, an inflatable light weigh reflective film, balloon filled with helium, glass, plastic or metal.The reflective surface inside the collector is obtained using inexpensive mirror coating which is applied to clear
glass or plastic.A cooling system is used for keeping the concentrated photovoltaic solar cell at or close to a fixed temperature to maintain the cell at its highest operating efficiency of power generation.
