Dear Dr.Tyagi i asked this question in front of biological view. for example photosynthesis process is one of the high efficient energy transfer processes in nature as i cited the link of article, similar photosystem is observed in animals like hornet. i think this is so inspiring to design photo reactors like what is done in planet or in epicuticle of the oriental hornet because nature tends to select optimum states and it uses the best of valuable energy.
just imagin one day you wear a clothe with ability of using photo system or designing ractors with the best quantum energy transfer with application in quantum computers.
