Prove That's Impossible To Increase Surface Area of Fluorescent

Bret, in actuality (real physics) there is no such thing as a one way mirror.

Partially silvered mirrors simply appear that way as a result of the light attenuation of the images passing though the partially mirrored surface making these images appear to vanish on the side of the mirror while highlighting images on the side more brightly illuminated.

What you appear to need for your purposes is a light rectifier, which in reality doesn't exist, although there are some liquid crystal light switches that can come pretty close.

problem,

What would one use a "light rectifier" for if it did exist ? Lasers , probably (and the optical equivalent of a C/W multiplier) ?

-A

Apparently fiber optics can be used to make all the light in a folded or spiraled fluorescent tube available, although at a price.

This only proves the exact opposite of what I set out to prove.

In any event there is more to the low intensity of fluorescent light problem than large surface area. Large volume is the real problem.

problem,

Nothing so trivial.

Creating free energy. Take a sealed box, make small box out of light rectifier. Place this inside the sealed box. Thermal radiation gets into the sealed box, but not out. It gets hotter, and you can run a heat engine off it, and heat the outside box without external energy input.

Hmmmmm If heat gets into but not out of the little box then where does the heat come from that heats the bigger box?

The energy is the key. Energy is being transported in the form of photons. High or low energy is immaterial. The energy in one photon might be later transported as two lower energy photons. As long as ANY photon can get through a "light rectifier", it will have the capability of providing heat. What a light rectifier implies is that anything with any temperature or energy differential at all can operate an engine for free. However, this violates thermodynamics. Therefore, no light rectifier can exist. QED.
