PFS receives patent on jet pack (without the jets) using ion electronic backpack for human flight with silent, vertical takeoff & landing.
SAN FRANCISCO, June 4 – Scott Redmond (http://www.sr1.com/html/scott_redmond.html ) has been awarded one of the most coveted patents in novel science, the patent for human electronic flight. One of Scott's start-ups, PFS (http://www.personalflightsystems.com ) , has developed an improved way to use new electrically charged, polarized, proprietary alloys to create thrust to lift small aircraft without the need for a propeller, jet, balloon or rockets. The recent posting on YouTube of previously secret government experiments with first generation versions of this technology has ignited new interest in the apparatus. The first generation experiments had always failed due to inefficiencies. The PFS technology solves those inefficiencies. In simple terms, the base technology uses the flow of ions from one electrode to another to move air which is pushed when these ions collide in an air medium. Electrons driven across an air-gap create a flow in that media when they collide with particulates in the air, resulting in thrust directionally opposite to the master cathode. Additional aspects of thrust have been measured beyond just air movement but no known tests have fully quantified this additive thrust factor. Several novel methods are used, by our team, to improve the performance and efficiency of the thrust, including: 1) a new design for capacitive thrust plates that emit and receive the electrical charges; 2) the conditioning of air between and around the capacitive plates; 3) the design of attachments to the lifting panel that help translate lift into horizontal thrust for directional control; 4) the removal of the heaviest component, the power supply, to a ground-based broadcast power system; and 5) automated flight navigation. PFS is now seeking partners to increase the understanding of the physics needed to commercialize applications of the technology. PFS has a number of working prototypes but acknowledges that those devices are expected to undergo vast improvement with additional resources. The Redmond patent overcame a NASA patent on related technology.
A good part of early funding for the technology will be used to shed more light on the physical concepts that make it work so new designs achieve better performance and efficiencies. For example, a voltage applied to two electrodes must be high-enough to create the ion process conduction current needed to begin the propulsion process. Normally ion collision begins at around 20,000 volts, a figure that PFS hopes to reduce, In this high voltage region, a gain of 1 watt's worth of thrust can be achieved by doubling the voltage. However, 2 watts of input power are expended to achieve one watt of ion process. The proposed studies will focus further up the efficiency curve to a region where new gains can be achieved. Previous investigations have focused on other areas because air does not typically conduct electricity at low frequencies. New investigations by Scott's Redmond’s (http://www.sr1.com/html/scott_redmond.html ) team, will focus on using a series of dissimilar atmosphere conditioners to assist a flight vehicle to operate in low frequency regions, where far more thrust can be achieved with the same energy input. Redmond says the next step is to source funding and development partners to build increasingly larger prototypes for efficacy studies.
