Excuser Technology

From BNE

Excuser technology works with the air not against it, separating the air before the vehicle enters it.

It's fuel is hydrogen, preferably in combination with oxygen in the 2:1 stoichiometric ratio in order to produce an explosion of pure water vapour.

By reducing air resistance this technology has the potential to enable us to travel anywhere on Earth in two hours; on renewable energy.

Excuser technology was invented by an independent research scientist and engineer, Mr. Sapoty Brook. He has founded Excusertech to provide a focus for the development of this technology.

Why is it called "excuser technology"?

It draws on the analogy of a person running through a crowd shouting "Excuse me, excuse me!" The louder he shouts, the faster he can go. The key feature of excuser technology is the separation of the air in the path of the vehicle thus reducing drag (air resistance).

How does an excuser work?

An excuser creates an explosion followed by an implosion.

First it expels some or most of the air out of the path of the vehicle. There are a few different ways this can be done, but the best way is to explode a two parts hydrogen to one part oxygen mixture in front of the vehicle with the explosion directed perpendicular to the path of the vehicle. The steam resulting from this explosion trails the explosion as a cylindrical plume or bubble.

When this plume reaches the nose of the vehicle it condenses (implodes) because the nose is cooled by a refrigerant, for example. The nose then experiences a reduced gas pressure and density, and the ambient pressure on other parts of the vehicle pushes the vehicle forward into the steam plume. Thus both thrust and reduced drag are generated.

Can lift be generated by an excuser?

An excuser can create a region of reduced pressure on any cooled surface. When a plume of steam makes contact with a cold surface it is drawn towards the surface by the pressure reduction. Newton's laws of motion ensure that an equal and opposite reaction occurs tending to draw the surface towards the plume. Thus lift is generated.

Can an excuser be used on the ground?

People, etc. must be shielded from the explosion and implosion. Given that, surface vehicles are possible.

Can an excuser be used underwater?

If an excuser is designed to operate independently of the oxygen in the air then it can operate underwater. The water can be used as a coolant for the condensing surface.

How fast could an excuser drive an aircraft? The speed of the air molecules striking the rear of the aircraft limits the speed (rms speed of air molecules is about 500 m/s at STP). Some extra source of thrust would be required for speeds to approach or exceed this speed. The reduced drag would then become the key benefit of the excuser.

What research needs to be done?

There are many factors which will influence the efficiency of an excuser system, or example: the delay between the explosion and implosion of a part of the plume; the size, shape, and intensity of the explosion; atmospheric conditions; the speed of the aircraft; the size, shape, and temperature of the condensing surface; etc. The influence of all these factors must be fully understood to build an efficient excuser system.
