Hello. I've been kicking an idea around for a while, and can't decide if it is worth pursuing. The main idea was to simply provide indoor lighting both day and night. The more evolved idea is to combine several current technologies to provide indoor lighting, power, heat, refrigeration and pure water. The basic premise is to have a reflective dish focused up into a small reflective dish that focus back down to a magnifying lens near the base of the first dish. The lens would focus onto a glass coil perpendicularly, so the top coil takes the main heat. The light that passes through the coil would travel fiber optic cables to provide indoor lighting. The coil would be water cooled (or conversely, the lens would focus sunlight onto the coil to vaporize the water) with water flowing upwards through the coil from a source. The steam would be used to power a small turbine for generating power, and then the water would be recaptured in a serparate tank. The excess air pressure could be harnessed to compress a tank. The compressed air could be used to cool a refrigeration box that has metal bands wrapping around the inside, small nozzles hit the bands with compressed air to provide refrigeration. Edge of large dish would have solar cells for trickle charging a battery. The dish would close up at night, and rings of leds around the magnifying lens would light up in an on-demand basis powered by the battery. Is this a feasible idea? I'm not looking for big efficiency in anything but the lighting, as the rest was something I came up with later. It just seems to me the main drawback on fiber optic lighting is strength of emitted light, but I haven't seen any systems that use magnifying lens etc to concentrate the light beam itself as it is collected. Is there a way to try to make the collected light more coherent? I know I'm tossing out several ideas simultaneously, but I thought all might be interesting for discussion.
