The herein invention is presenting a lift generating method based on a semi-open fluid jet flowing in a closed circuit around a lifting airfoil. A VTOL aircraft with maximized payload room and car-like shape is the preferred embodiment of the invention. The herein aircraft uses no wings, exposed propellers, hot gas jets or other high injury risk means for propulsion and lift, and it can be driven by ordinary skilled people. Furthermore the aircraft has a small footprint and can land, take off and even cruise on water in one of the preferred embodiments.

1. A system for a vehicle comprising: a lifting foil positioned within a containment body, the containment body having a longitudinal axis extending from a first end to a second end;a first flow path having a first fixed height positioned between the lifting foil and an upper surface of the containment body;a second flow path having a second fixed height positioned between the lifting foil and a lower surface of the containment body, the first fixed height being less than the second fixed height;a safety cover forming the upper surface of the containment body, the safety cover including a plurality of vents allowing fluid communication from the first flow path to an outside atmosphere, the vents being positioned in a direction perpendicular to the longitudinal axis of the containment body, the plurality of vents being the only fluid communication from a position within the containment body to the outside atmosphere. 2. The system of claim 1, wherein the first flow path is an active path allowing fluid to flow from the first flow path to the outside atmosphere. 3. The system of claim 1, wherein the second flow path is a passive flow path, wherein fluid flowing through the second flow path remains within the containment body. 4. The system of claim 1, further comprising: a plurality of ducted fans positioned between the first flow path and the second flow path. 5. The system of claim 4, wherein a first end of the plurality of ducted fans is positioned adjacent to the lifting foil and a second end of the plurality of ducted fans is positioned adjacent to an inner sidewall of the containment body. 6. The system of claim 5, wherein the plurality of ducted fans are configured to move fluid from the second flow path to the first flow path. 7. The system of claim 4, wherein the plurality of ducted fans are positioned in a single row between the lifting foil and the inner sidewall. 8. The system of claim 1, wherein fluid flowing throw the first flow path has a different speed than fluid flowing through the second flow path. 9. The system of claim 1, wherein the second flow path is a closed flow path, and the first flow path is an open flow path. 10. A method for moving fluid comprising: positioning a lifting foil within a containment body, the containment body having a longitudinal axis extending from a first end to a second end;flowing fluid through a first flow path, the flow path having a first fixed height positioned between the lifting foil and an upper surface of the containment body;flowing the fluid through a second flow path having a second fixed height positioned between the lifting foil and a lower surface of the containment body, the first fixed height being less than the second fixed height;forming, via a safety cover, the upper surface of the containment body, the safety cover including a plurality of vents allowing fluid communication from the first flow path to an outside atmosphere, the vents being positioned in a direction perpendicular to longitudinal axis of the containment body, the plurality of vents being the only fluid communication from a position within the containment body to the outside atmosphere. 11. The method of claim 10, wherein the first flow path is an active path allowing fluid to flow from the first flow path to the outside atmosphere. 12. The method of claim 10, wherein the second flow path is a passive flow path, wherein fluid flowing through the second flow path remains within the containment body. 13. The method of claim 10, further comprising: positioning a plurality of ducted fans between the first flow path and the second flow path. 14. The method of claim 13, wherein a first end of the plurality of ducted fans is positioned adjacent to the lifting foil and a second end of the plurality of ducted fans is positioned adjacent to an inner sidewall of the containment body. 15. The method of claim 14, further comprising: moving the fluid from the second flow path to the first flow path via the plurality of ducted fans. 16. The method of claim 13, wherein the plurality of ducted fans are positioned in a single row between the lifting foil and the inner sidewall. 17. The method of claim 10, wherein fluid flowing throw the first flow path has a different speed than fluid flowing through the second flow path. 18. The method of claim 10, wherein the second flow path is a closed flow path, and the first flow path is an open flow path.
