Can one laser light be use for intire house and uses less energy by making pipe line system that dont burn?

Answer 1

Lasers are extremely ineffficient sources of light, though (a few percent). I saw a news clip where piping sunlight in plasic rods that function like big fiber optics is being studied. Sunlight is focuses onto the ends of the rods on the roof. The idea is to save electricity during daylight hours wherever windows or skylights are unavailable or inadequate. It's much more efficient than photovoltatic powered conventional lights because you can skip the (inefficient) electrical conversion.

Answer 2

You are on the right track. Check the net for the sulphur or sulfur lamp. This uses light pipes. It is not suitable for domestic installation since it lights a very large area. The advantage of small light bulbs as invented by Swan and Edison is that they are suitable for use in a single room. The most efficient lighting for domestic use presently available is the full size fluorescent lamp, the compact fluoro.is next. In the very near future white LED lamps may become useful, at present they produce a very directed light and are not suitable for use with most available diffusers.

Lasers are not suitable for domestic lighting as they produce monochromatic light, that is, a single wavelength. Domestic lighting requites near-white light, which is a mixture or all colours.

Answer 3

You sound very intelligent, and your question is quite interesting. I cannot for the life of me figure out how you could misspell "entire."
