I think they have been around for awhile but still quite expensive for the everyday consumer. I cant remember of the top of my head how it
works but i think an electrical charge or field runs through the glass and somehow interacts with crystals or liquid crystals... i might be wrong
It works pretty much the same way in which games that have liquid crystal displays in them work, In the games there are predesignated arias where the
screen changes, or darkens when a charge is added and clears once the charge is removed. The glass works in a similar way, when no electrical supply
is added to the glass it is clear, when the electrical charge is added the glass darkens.
As far as the plane technology goes, I would think that they would need much stronger material to withstand the strains of flight.
As far as the other poster saying that we should be beyond the need for airplanes in 40 years, though we have advanced in the past 40 years, I don't
see us evolving to a point in 40 years where airplanes are a thing of the past.
Air transport is too big an industry, unless private parties with allot big supporters come along, I don't see it changing anytime soon. Just look at
the private companies trying to bring space to the general public, it just costs too much, eventually they may get the cost down, but I think that
would take at least a hundred years, not just a couple decades.
I could be wrong, and would love to be, but the pessimist side of me can't but help to see things this way.
