Taku concept of building nuclear space crafts ,nuclear run trains , nuclear airbuses with double halls or story crafts that is to say with up and down floors.
The atoms of uranium and others radioactive elements when split and harnessed, is a magic fuel to banish all sort of jet fuel and it highly polluting tendency but the reactors must well designed so that it will never lead to an atomic explosion and the crafts must be constructed in the form the if the reactors become e pest to the craft it could be automatically separated from the spacecraft or aircraft with harmless endeavors towards the smooth running of our precious crafts.
For the nuclear-space crafts the propelling force must be able to make the crafts run at zero or neutral gravity, for this to happen the nuclear-space crafts should be build in terms of weight and not mass, secondly, the crafts should be lunch through the equator since the gravitational pull on reduces in the equator and the propelling force to lift the nuclear space craft should about thirty times above the weight of the crafts so as to enable the crafts to fly a great negative gravity. Will every be possible to build vehicles that can run for 60km per hour with a quarter or half a litter fuel? I hope this will be the only way to conserve our fast disappearing energy sources
