The Japanese have installed in there office blocks fiber optic cables running through the entire length of the buildings and branching out into office spaces flooding it with sunlight, I read somewhere they save 40% on energy costs alone but utilizing the sunlight, also they have special flower pots with grass and flowers growing in the rooms each being supplied with its own little fiber optic light source.
That was an interesting video thank you for posting it.
Happy days Anthony.
