JOHN H. KELLER PHD
I am a Ph.D. Physicist who is internationally known in both the fields of Plasma Physics and Ion Beams. After an early retirement I concentrated mainly on Hydrodynamics and more particularly Sailboard Design.
My 1st paradigm shift was inductive plasmas for plasma processing, which now makes up over half of the field.
My 2nd paradigm shift was extracting and de-accelerating ion beams. This helped give the ion implant company, I invented it for, such an advantage that their main competitor stopped making ion implanters and then bought them for $4.9B.
My 3rd paradigm shift involves the cambered planing surface and rockered/cambered surfaces ending in an upward slope on the bottom of watercraft hulls.
I have a total of over 40 patent inventions see http://patft.uspto.gov . These include:
Three issued sailboard patents
Two patent pending watercraft/sailboard PCT patents
The first to invent Inductive Coupled Plasma, ICP, for plasma processing.
The first to invent and patent electrostatic deflection and scanning of high current ion beams.
Extracting and de-accelerating ion beams
Bright RF Plasma Beam Source
Multipole Implantation-isotope separation ion beam source,
Many Ion Beam Implantation patents
Many RF Plasma Etching patents,
3 Electrostatic Chuck patents,
High frequency plasma for etching oxides,
Ion beam helicon Plasma Source.
Cambered/Rockered High Lift Surfaces reduce drag about 40% and increase Lift to Drag about 100% from transition of the hull displacement mode through planing speeds!
The camber/slopes steps for sailboards function like a step at fast planing speeds but are unlike any other step in both how they look and how they function as steps. This is because they have almost no wave or turbulence drag unlike other vented or un-vented sailboard steps. They have the following demonstrated properties (see the following figs.in Board Data).
1) A board with these camber/slopes planes at the same force as the same board without the camber/slope (see data fig. 6 series 1 vs. 2).
2) At higher planing speeds the board has less drag, 15-30 %, and faster speed (see data figs. 5-7 and sailing data).
3) Because of (1) these camber/slope steps can be placed further forward which allows the board to plane at a more optimum angle at higher speeds and results in (2)
4) The camber/slope steps are designed to prevent ventilation of the fin.
5) Sailboards can now be designed with a wider back yet at high speed will have a narrower back planing surface.
