Ilan Scheinkman shares his idea about how virus DNA can be used to send covert messages.
Russian construction firm AB Elise has proposed turning one of the world’s largest opencast mines into a futuristic domed city.
Tower blocks needn’t be the only answer; it is possible that as well as expanding our settlements into the sky, we might also expand outward onto the oceans. This could be done by constructing enormous floating cities.
Might future settlements become entirely linear, being shaped to fit the highways rather than highways being shaped to serve the city? Might the city and the highway actually become the same thing?
To teleport Captain Kirk, we need to scan him and find out every detail about his body (a sickening idea, I know). Every particle needs to be put back exactly where it was or Kirk might turn into a pile of goo, a vapour, or worse – an evil version of himself from a parallel universe.
The idea is to have a portal without a definite shape and without definite borders. Most portals in science fiction are circular, but these portals would be more like an endless barrier, ribbon or crack, and they could conceivably stretch across the globe.
The airborne wind turbine (AWT) uses a a helium-filled inflatable shell to rise to high into the air where winds are stronger and more consistent, making it much more reliable than conventional land-based wind turbines.
Engineers and scientists located at NASA or aboard the International Space Station can control the motions of a number of remote controlled vehicles that would work in concert to terraform Mars.
This very simple idea could see spacecraft reaching incredible speeds. The basic Project Orion design could have traveled to Mars and back in just 4 weeks. A trip to Saturn’s moons would be cut down from 9 years to just 7 months.
The space stations of today are little more than tin cans, but the space stations of the future are likely to be much more impressive. For decades, scientists have been predicting what shape future space stations might take. Here are some of their most enduring designs.
The wormhole is the simplest and most elegant mode of transport science fiction has to offer. It’s a tried and tested narrative device – a good old-fashioned “magic doorway” with little scientific explanation required.
Faster-than-light travel is one of the most revolutionary ideas science fiction has ever explored. This simple narrative device has made it possible for writers to explore distant worlds and expand human civilization out into the depths of space. However, it’s worth noting that FTL is just that; a narrative device – a means to an end.
I recently came across this article on space.com and did a fair amount of head scratching. It details a new idea to use a combination of water and solar power to propel spacecraft. The technology is sound and the spaceship design is actually pretty clever.
