How will be the WORLD after 100 years

I'm thinking that if we aren't careful with all this pollution and war - the only ones who will have to worry about getting around may be the paramecium.However, if I let my imagination free and assume that we humans survive the current state of affairs and try to conjure up what transportation could be like in 100 years, I suspect we will be using a propulsion system based on pulling the power right out of the atmosphere and the sunlight and will have dropped our primitive system of using fossil fuels as well as the (purely profit motivated) system of having raw electricity forced through wires. Tesla's designs made this unnecessary from the start of the 20th century.The vehicles will then be very different - lighter and mostly using some form of flight for all but very local travel and will not need roads and highways so much as very well organized flight paths. Local urban travel will be only by use of publicly controlled vehicles following carefully organized grids which will be part of the buildings themselves and will not require the type of road systems as at present - so there will be walkways and nature where we now have roads and highways, throughout the towns and cities. Personal (publicly owned and maintained) vehicles will be smaller and lighter and will fit together in such a way as to make them stackable and easy to store and access from vehicle tubes that will be affixed to the buildings. Timeless visual designs will highlight the beauty of the materials used, being kept sleek, simple, uncluttered and efficient and with features that ensure optimum simplicity for implementing advances in technical details. Planned obsolescence will by then have been declared a punishable offence and will have been replaced with production that is rewarded for the longevity and upwards mobility of the design. Advances in the technical details will be frequent (since the creativity will be directed into improvement of functionality rather than extreme competition for sales) and will be inexpensive and easy to implement. Imagine what could already have been done by now if the money funneled during the past 100 years into war and the physical and mental machinery of the subjugation of most by the few - for personal power and material gain - had instead been used to develop and improve life for everyone.Dream along with me...
