I wonder if the capturing of wavelengths of light through “stretching” have anything to do with Einstein’s Theory of relativity and how the conceptualization of bending matter/anti-matter fields through a time continuum have any catalysts such as the ability to capture and stretch light?

Well said, but we all need to realise that adding Solar on their house is an purchase which could boost the longer term value of their residence if / when they decide to sell. With the environment the way it is going we simply cannot dismiss any system that presents no cost electricity at no cost to both the customer and more significantly the world!

Interesting, might be yet another path to high (i.e. room) temperature superconductivity, see e.g. http://jpsj.ipap.jp/news/jpsj-nc_91.html

This funnel reminds me of Vortex energy swirling in the universe and also the A field Akashic field that carries all energies known and unknown to man funneling into human brain through the awakening of the Kundalini energy in human body. This is for sure imitation of Nature itself, if we succeed, this is it, to revolutionize energy for all.

Seems to me this would be good if you had multiple layers over the entire “surface” that responded to different wavelengths and thereby could “catch” all the incoming energy. But light of all wavelengths uniformly hits this surface everywhere. It seems from the description that different circular “bands” of different radii simply are “stretched” to respond better to different frequencies. Either that effect would average out over the surface or – if one frequency band was “better” than any other – why not cover the entire surface with a material elastically strained that particular way?

Light is electromagnetic wave with a large spectrum: micor-wave, infrared, visible light, UV, X-ray… Current Si-base solar panel capture only a small portion in that spectrum i.e. visible light, mostly yellow to blue. This limitation is due fixed energy bandgap in silicon (I believed it’s 1.1 ev). By having material with variable energy bandgap we can capture and convert light energy from other spectrum hence will improve the efficiency of the solar pannel.

Capturing more of the solar spectrum means higher efficiency in future solar collectors and lower cost for electricity.

very technical article, who could summarize this? What excactly does this mean in practicality when this is applied to solar panels / solar technology?
How does this work?

sounds like a pulsating electric engine could be developed from this tech.
