Carbon nanotube antennas intensify solar energy

Comment

It seems that it is MUCH cheaper just to use an inexpensive Fresnel Lens to concentrate the light versus carbon nanotubes!! Typically there are optics the direct concentrated light to the solar cell like Sol Focus (www.solfocus.com) or Amonix (www.Amonix.com) or in the case of a Rainbow Concentrator will separate and concentrate the light like Sol Solution (www.sol-solution.net). Using carbon nanotubes in solar energy is so ridiculously expensive that it is laughable.
