In 2015, declared International Year of Light by UNESCO, there is much talk about photonics, that is to say technology connected with light. It is widely believed that photonics will assume the same importance and diffusion in this century as electronics did in the last century. One mainly thinks of lasers and their applications, photonic computers, the use of infrared technology for night vision, optical fibres for communication and such like.
However, little is said about the great energy of red and long waves. The various light waves arriving directly from the sun and stars or bouncing reflected or refracted off things around us are interpreted as colours by our brain and eyes. We also only see a small part of the light spectrum, namely light waves between 400 and 750 nanometers. From 0 to 400 nanometers, outside of the visible spectrum, are the ultraviolets, whilst the various shades of blue, that is to say “cold” light, can be found at between 400 and 500 nanometers.
Solar Pump NS1 uses warm light, long waves in shades of red of between 600 and 750 nanometers, but also the invisible area of infrareds, which goes well beyond 10,000 nanometers. That enormous band of invisible light contains all of the warmth needed by humanity and the other creatures living on the Earth. Even the background radiation generated at the start of the Universe is found in this part of the light spectrum, at the end of which are the radio waves. Red provides us with the energy needed to move our motors and much more could be done by simply collecting the long waves. Great is the power of red!
