Cleaner air comes with better temperatures and possibly lower fares. The future is almost here -- the ideas have been present for centuries and the means to create them are here to help make things better for everyone, including travelers.

According to the Foundation for Economic Education, the world is seeing software becoming a dominant force in all industries, including the transport industry. Writing for FEE, Niskanen Center Civil Liberties Policy Analyst Ryan Hagemann said that driverless cars -- currently researched by the industry and is aimed to arrive on 2020 -- would drive down costs "associated with human-operated vehicles," including accidents and insurance.

The electric car -- spearheaded by transport tech giant Tesla -- the "Hyperloop" by Tesla, which aims to use electromagnetic propulsion through tubes to accelerate pods containing people, will use the same technology as Japan's "MagLev" train lines but with a cheaper approach. If successful, the Hyperloop could save travel all around the world once implemented.

Solar flight -- or the ability to use solar energy for travel -- will not only create sustainable travel economies. It could also cheapen the need for plane fuel. The only way to guarantee cheaper travel rates is if solar technologies become cheaper. The Matador Network believes it would only cost $1 should solar flight become the main resource for flight fuel.

The travel website also said China's plans to create a London to Beijing rail, the world's first inter-continent train line, would cover the entire distance only in the span of two days -- if successful. The train line might possibly use the same MagLev technology from Japan to guarantee high speed, stability and less maintenance.

As for space tourism, Virgin Galactic and SpaceX's rocket-fueled inventions have fared so far, but the momentum is still swinging and the two organizations set to explore space tourism technologies are likely to find discoveries and developments that would contribute immensely to the industry's development in the coming centuries.
