This document is not intended to be exhaustive, but rather to describe a principle and initiate further discussion.

The path ABCDEFG can be a faster path than the path AG

The curve AB is a parabolic curve equal to the path of free fall at point A at the maximum expected initial velocity and point B is where this curve is tangent to a 45° line.

The line BC makes a 45° angle with the normal and is tangent to the curve AB.

The arc CD is a 45° arc and is tangent to the line BC, and it's a radius is optimized by being as short as possible while respecting the size of the vehicle and tolerances for the g forces during this part of the path.

The arc DE is a 45° arc and is tangent to the arc CD and has the same radius.

The line EF is tangent to the arc DE and makes a 45° angle to the normal.  It's length is a factor of the curve FG.

The curve FG is a parabolic curve and it is equal to the expected path of a projectile at  point F.  It is tangent to the line EF. It is also tangent to a line parallel to the line AG and in this case is drawn tangent to the line AG.

The height AD is determined by factoring in available construction techniques, drag, and available thrust among other factors.

The angle
a is any feasible angle (generally a<45°).

 

A numeric example

For the sake of simplicity, in the following example the curves AB and FG are set to be of zero length.  Also, it is assumed that there is no drag and/or friction.  In this example the path ABCDEFG is more than four times faster than the path AG. The average speed along the path AG is 68.06 km/h while the average speed along the path ABCDEFG and in the direction AG is about and/more than 284.86 km/h.

The angle
a is set at 1°, only for the purpose of describing this principle and not because a height difference at points A and G is required.

 

Considerations for drag and friction

The exact calculations of drag and friction are beyond the scope of this document at the present time.  However, in my opinion the following experiment proves that the principle can be true in the presence of drag and friction.

About the apparatus

The apparatus shown in the video is fabricated according to the following drawing.  It is not designed to optimize the presentation, rather to be easy and fast to fabricate using the materials that I had available.  The design incorporates a marble and a shooter marble, so that it would be clear which marble finishes first even without filming the process.



Conclusion

In conclusion I would like to state the following:

For any two points on the surface of the earth that a straight line going through them makes an angle greater than 45° with the normal, there exists a path faster than a straight line passing through these points for any given thrust greater than zero and drag. This can be achieved by substituting part of the straight path by a profile roughly that of a right-angle angle whose two lines are at 45° to the normal.

In my opinion this principle will inevitably be incorporated in the transportations of the future, simply because the laws of physics make this a faster path.

In addition, the further the distance that is to be traveled, the higher the average speed will get. Drag has the effect of limiting the maximum speed, but this issue can be addressed through the design of the vehicle and thrust and other techniques which can be discussed at a later time.

This demonstrated principle can probably be best utilized in an equivalent  spring operated design as well as it's electronic equivalent.

This principle does not violate the law of conservation of energy and matter.  It merely takes advantage of the fact that every object on the surface of the earth has a potential energy and that its potential energy would be the same anywhere else having the same altitude.
