Rising fuel
prices are slowly killing airline companies. Can ocean liners save long distance travel and tourism?
Flying has become cheaper than taking a train or
driving a car. Yet, environmental
concerns, dwindling fuel reserves and fast rising kerosene prices are
threatening
to turn airline travel into a privilege for the rich again. This should
not
mean the end of mass travel or tourism, however. Before mass air travel
took off in the 1960s, people crossed the globe in majestic passenger
ships. Reintroducing ocean liners would be more than a nostalgic move:
it could be a much more energy efficient (yet slower) way to travel.

If water,
sewage, gas and oil can be transported through underground pipelines, why not consumer
goods as well?
Some
Western European countries are getting serious about transporting consumer goods
through automated subterranean networks – introducing a fifth transport
mode next to road, rail, air and water. This rare combination of low-tech sense and
high-tech knowledge could lead to a further economic growth without destroying
the environment and the quality of life. Super fast underground cargo transport
is a favourite subject of futurologists. Yet, the key to the feasibility of the proposed systems is their very low but constant speed.

The Museum of RetroTechnology has an amazing collection of
pictures and drawings of motorized monowheels. These one-wheeled vehicles (the
driver was placed inside the wheel)
evolved from pedal-powered monocycles at the end of the 19th
century. They became sort of a wet dream for boffins during the first decennia
of the 20th century.

If racing
cars can drive on solar energy, then why do normal cars still need fossil fuels?
Around 30 cars
race 3,000 kilometres across the Australian continent in the “World Solar
Challenge”. Solar cars are electric vehicles that generate their own
electricity, by means of around 6 m² of solar panels installed on their bodywork,
and a series of linked up batteries that serve as a fuel tank. If we want
the car to survive in the longer term, it should become slower and lighter
again, trimmed to the efficiency of solar panels and batteries. (Picture: Venturi Astrolab)

Considering
the wind as an extra source of power, the fuel use of cargo ships can be reduced
substantially.
Steam power
and diesel engines relegated cargo sailing ships to the history books, since
motorized ships are a lot faster, cheaper and more reliable. But now that the
fuel use of ships and the ecological damage involved passes all bounds, there
is a renewed interest in wind power as an extra source of energy; thanks to an
extreme water sport.

Air freight is the most
ecologically damaging mode of transport. It becomes the most eco-friendly option
if speed is reduced.
An American company, Ohio
Airships, combines the advantages of air cargo while significantly reducing
ecological problems. They achieve this by designing slow cargo airships, called "Dynalifters". These air vessels mix the travel concepts of planes and Zeppelins.
They can carry 3 times more freight than a Boeing 747, but travel at a speed of
only 200 kilometres an hour, consuming considerably less fuel.
