How to make a flat sheet(like tin foil) into a parabolic shape for solar energy

copyright all rights reserved How to make a parabolic shape from a flat sheet, I discovered that by attaching corners of screen, covering with 50/50 cement, screened sand mix, instead of water, Elmer’s glue, then cover with plastic, weighing it down with sand forms a parabolic shape from the flat sheet of screen when it hardens. I cover with tin foil, attach 4 corners of sheet, then covering with plastic, weighing it down with sand forms a parabolic shape from the flat sheet of tin foil, seal rest of foil , add valve and suck the air out creating the most powerful solar energy lenses ever seen!

First you make cheap solar lenses…the basic idea…

Then you use lenses to light Plasma of a short wave light.
The problem with solar electric is Sun light is mostly Heat, only a small percentage of Sun Light is Ultraviolet(Short wave) that photovoltaic cells make electricity from.
Like a Neon tube that makes white light, that uses a electricity to light plasma, my idea is use light from a focus of many lenses(heat) to light the short wave tube(like tanning bulb, that make mostly Ultraviolet & Short wave) and the light goes to a small cheap photovoltaic panel(By doing this I am changing almost all heat energy of Sun to Short Wave, this is what photovoltaic panel use to make electricity). I expect to go from what we get now 5% efficiently to 50% efficiently.

So this will make electricity cheap for running air conditioners and refrigerators.

Second idea..on lenses…

All that is needed is large, cheap, efficient lenses, this method of turning a flat sheet to a parabolic shape (efficient) and cheap method(cement screen) that can also make large lenses….
the Video above…

One problem left, I am using tinfoil that I solder and takes a lot of labor, if I used 100% reflective window tint I could use heat bonding and quickly manufacture!
