my idea is for a government or forward-moving organization to sponsor design competitions to design a better, more spacious, green and futurist “seating” area for both trains and planes that maximizes the concept of how we use that space more than packing us in like sardines for profit. you could use the standard seating quota as the parameters for the competition, perhaps a $100,000 prize and recognition for the winner. a conscientious government (it may not be ours) can give a tax incentives or contract to the airlines & train that start adopting these cabins that work towards the future and design with health, comfort of the passengers and rethinking of a better space. better design is the low hanging fruit of saving energy, health and comfort for all. it just needs attention, publicity and sponsorship. please don’t leave it to these industries; it goes under “luxury” in their book. make it a public cause.
