This is Part 6 of a 15 part Series on how I think life will look like in 100 year assuming Global Warming is in full effect. Some Parts refer back to other Posts in this Series. [Major revision 11/30/2018]
In 100 years cars will be history. They simply use far too much energy, take up far too much space, are too large and heavy, need too many resources to manufacture and maintain, and produce too much heat. So much smaller mobility devices and pods for individuals and small groups of people will be in common use. Since housing in the future will be underground, moderate to long distance travel will be achieved by pods containing up to six passengers traveling in Hyperloop like long vacuum tubes and tunnels that travel up to 1,000 mph for the longer distances. These long tubes may cluster in large bored tunnels then branch out again. They may branch off into another tube, like railroad tracks do when switching to another line. When dropping off passengers the pods switch off the trunk tube to a siding tube and decelerated to a station at normal atmosphere where passengers get off and on then accelerated back to the trunk tube again. For shorter distances they would run at appropriately slower speeds. All pods in the same pod-tube go at exactly the same speed and direction to avoid collisions.
For shorter distances people would use self balancing electric autonomous bicycle like devices or self balancing electric autonomous scooters that one could ordered to self drive to where one lives then take one to wherever they wants to go. They can drive onto magnet levitation tracks to take people further distances, all faster and at the same speed, than the normal roadways which are more like sidewalks. There may be many different levels of these roadways in this underground world.
It is also possible that submarines carrying hundreds of people under the ocean will move more slowly between continents in great comfort. Surface ships will simply be too exposed to the elements for long distance travel due to frequent mega-storms at sea due to Climate Change. Submarines using salt water electric drive engines powered by Fusion Reactors described in Part 3 – Energy will move sea water at very high velocity through powerful electric ram jets for cavitation free, low friction propulsion, at speeds upwards of 300 knots. A frictionless membrane material or some other technology to lower drag under water will cover the surface of these submarines. They will also be geometrically shaped for least resistance through water. Submarines are quite suitable for ocean travel to avoid sever surface storms due to Climate Changes. Freight may also be moved by larger submarines. New technology will chase large sea animals out of the submarine’s path with sound waves and long rang 3D radar like technology will enable visibility for many miles ahead even in murky waters. Submarines will be able to go over twenty thousand feet under oceans to find areas with less sea life to increase speed without concerns of collisions. These will all be autonomously directed and maintained by robots. For short distances smaller mini subs using fuel cell with the same smaller version propulsion system will be used. These can link up with the larger subs for ferrying purpose.
Rocket travel over the stormy atmosphere taking off and landing vertically in underground silos, like in James Bond movies, might be an alternative means of traveling long distances quickly over the weather. Perhaps a new meaning of rocketless propulsion might be developed in the future that produces less exhaust. Space craft like this should be much smaller by then today’s with different types of advanced propulsion systems.
It is highly unlikely that man will have to live on other planets. No matter how bad Climate Change is, Earth will likely be far more habitable than any other planet in our solar system. Mars lacks the water, oxygen, and other resources our planet will still provide for the way our species has evolved.
