First Prototype

This prototype uses a modified linear Fresnel lens.
The patented lens concentrates and spreads the spectrum with a single lens.

The prototype lens is composed of two lenses facing different directions.

The picture below shows the spectrum being separated and concentrated.
The bands have about 10 times the normal energy from the sun.
The actual implementation will have between 80 to 300 times the energy.



In this picture the concentration is less, but the spectrum spreading is greater.



This shows how a three solar cells could be used.
The InGaP absorbed most of the visible spectrum, but there is still a lot of energy (about 1/2) that is not visible.
