I know some of you, well Desirod, make a living through designing lighting, so perhaps you can explain. I came across various buildings which make use of daylight for interior lighting through using tubes, deck prisms and mirrors guiding the light to where required.

Web searches throw up many new buildings, underground stations [Potsdamer Platz, Berlin] and more, already using this technology [since 1986, HSBC Hong Kong] and German companies experimenting on setups to guide sunlight into buildings.

Surely ideal for ships?

I do work with Daylighting, Bruce is correct about solatubes. Today's modular cabin design allows for easy installation. A large side emmiting fibre optic system could work. One tube could cover inside cabins in line over 10 decks.

Solatubes are an end emmiting system which would require one tube for each inside cabin, and with 10 cabin decks the space to install is not there.

Canberra's court cabin setup IMO is a
brilliant design that could be used on land in large footprint buildings

One can be in a room with many large windows along the side, but with the glare & nothing from above, still be in a darkish/dismal room overall. It needs a bit of 'redirection'. Whole glass sides as described in the Radiance Class is much better.

Without direct access to exteriors use can still be made of natural light. I suppose with more research in time this might become the way of doing without artificial light, for part of the day anyway.

Modern passengers will pay a premium for a port hole, window or Balcony, but would they pay extra for just natural light?

Actually on the Oasis Class there is much more natural light in the Royal Promenade. There is a large glass skylight that lets in natural light and also adds a nice design feature to Central Park, which is directly above the Royal Promenade. In addition the Rising Tide Bar lets in natural light as well. The natural light and the fact the Royal Promenade is much wider on the Oasis Class really enhances the venue.

The Solarium is another great use of natural light on the Oasis Class.

Really Doug? I thought that the Royal Prom on the Voyager and Freedom class was purely illuminated by artificial light.

Maybe you are thinking of the glass cone on the pool deck?
There is a "light well" all the way down to Royal Promenade, but there isn't a lot of natural light coming that way if I remember correctly.

Here is the cone with colored glass.

The lower end of the "light well" is in the roof of the Royal Promenade.

I think this design is used only in Voyager of the Seas and not the other Voyager/Freedom class ships.
