Abstract: A transportation system for people as well as goods that preserves energy by utilising the zero energy travel principle where energy is recycled instead of being wasted as heat or noise. An air tight and self-contained carriage (400) travels in a low pressure tube (100) that is completely sealed in order to maintain the low pressure. Electrical vacuum pumps (200), each equipped with a release valve, are used to remove air or discharge air that is above the desired low pressure, inside the tube (100), and are operated in such a way that the vacuum pumps help the propulsion of the vehicle. The carriages (400) or vehicles (450) themselves help in creating the vacuum by being fitted with seals (300)(350) that can vary in shape and size so as to allow the vehicles (400)(450) to behave as a vacuum pump or to allow the vehicles (400)(450) to be propelled by excess air pressure at the back due to the switching off of vacuum pumps (200) or leaked air.

Abstract: A vehicle for transporting people as well as goods that moves with minimal aerodynamic drag loss because the energy in the aerodynamic drag is transferred to the propulsive thermal engine. The high dynamic air pressure in front of the vehicle (1) as a result of the vehicle (1) moving faster than the surrounding air is sucked by the air compressor (10) through the air intake (5) and variable sized air intake nozzles (2)(3). The low dynamic air pressure at the back of the vehicle (1) as a result of the vehicle (1) leaving behind the surrounding air, is filled back by the exhaust gas coming out through the exhaust nozzles (6). All the nozzles (2)(3)(6) are optionally adjustable in order to optimise the sucking and filling capacities of the thermal engine. The present invention also applies to flying vehicles, road vehicles as well as but not limited to underwater vehicles.
