Huge airships containing apartments and aqua-village floating holiday resorts are among tourist developments that could feature by 2030, according to a report today.
The airships would be vast structures featuring bars and restaurants, the report for Thomson Holidays by trend forecasters the Future Laboratory said.
The aqua-villages would harvest energy from the sun, wind and rain and could be moved from one location to another.
By 2030 the travel world could also see the largest airports transformed into aerovilles – destinations in their own right, featuring cinemas, hotels and restaurants.
In 20 years, second-generation biofuels developed from algae could be mixed with jet fuel to power aircraft with significantly reduced carbon emissions.
The report also looked at the hotel room of the future, which might feature:
A water-efficient bathroom where water from the wash basin and shower is used to flush the toilet;
High-efficiency windows that minimise glare and heat in the room;
Low-energy ceiling lights powered by the resort's own wind turbines and solar panels;
A personalised climate control system that automatically understands the occupant's optimal temperature settings;
A heat-activated touchscreen to communicate information on the occupant's energy use, sustainability and other resort activities.
