June 8, 2007 This has to be one of the most 'futuristic' developments we've seen in some time; a new U.S. patent has been awarded to a company that has plans for a safe, silent personal flight device using electromagnetic ion propulsion as its primary thrust generator and drawing its power wirelessly from earthbound inductive green power broadcast stations. California's Personal Flight Systems are taking a serious look at the future of personal flight, and the technology involved will leave you shaking your head.
It's been seven years now since the dawn of the new millennium, but it just doesn't feel like we're living in the future we were promised in the 1980s. There's no teleportation - fair enough, that still seems a bit far-fetched. No cure for cancer - well, at least they're making progress. There doesn't seem to be any good reason, though, why we can't have cheap, safe, fun commuter jetpacks to fly around with. It's been over 50 years since the first working prototype jetpack was flown by Bell Aerospace, and the few companies that actually have a working jetpack are using a modified version of the same design, and are unable to sustain flight beyond 30 or 40 seconds. C'mon science, where's my jetpack?
Thankfully we occasionally hear of efforts to rectify this gaping omission from the personal mobility sphere, and this latest one is worth a special mention, both because of who's behind it and because of the fascinating technology it leverages. Silicone Valley startup Personal Flight Systems (PFS) has recently been awarded the patent for personal flight using ion electronic air propulsion - a clean technology that has none of the dangerous explosive risks involved with combustion engines.
Ionic Air Propulsion The basic principle behind ion propulsion is to positively charge a fluid and then electromagnetically propel it to create thrust. It's a very efficient technique that NASA have been using to propel long-distance, unmanned space vehicles. While the amount of thrust it produces is quite small, it can be sustained over a long-term trip to provide a very effective cumulative acceleration that eventually far outweighs the much more powerful but fuel-hungry chemical rockets used for take-offs.
Simple ion-propulsion craft, such as those shown in these videos, can be easily built and are thus often a popular science fair project for students.
The PFS patent adds a few key elements to this well-established technology; most importantly a new design for the capacitative thrust plates that emit and receive the electrical charges, and a system that pre-conditions the air between and around the plates to maximize thrust. The company also plan to remove the heavy power pack from the vehicle and "broadcast" pulses of DC power to the vehicle from ground stations based on theories from Nikola Tesla, the famous inventor and physicist responsible for the AC power system in the early 20th century.
PFS claim their ion-propulsion personal flight vehicles will be safer than helicopters or rockets, with their massive moving parts and explosive gases respectively. Ion propulsion, however, carries its own set of risks - particularly an elevated risk of throat and lung cancer if an individual is to breathe in too much ionized air - although this can be mitigated through a number of techniques.
Interestingly, many of the vehicles described in the patent make use of chemical rockets to provide initial and additional thrust, thus re-introducing some of the safety risks the device seems keen to avoid. And the design of the devices, which in their personal flight form seem to look like a strap-in Segway with an umbrella attached, won't make them particularly portable.
Still, the end result appears to offer a safe, silent personal flight system that runs primarily on ground-based green power, and the fact that this new patent overwrote existing NASA patents in the field shows that the PFS solution is viewed as a serious innovation with real-world potential.
The Inventor PFS is a start-up by Scott Redmond, a San Francisco-based tech executive and self-described "venture solutionist." While nobody talks his abilities and achievements up quite like Redmond's own webpage ("superhero-like ability" is quite a statement!), he is unquestionably an overachiever.
His recent projects have been focused on green, sustainable and new energy, including sustainable and self-powered homes like his NowHouse demo home, various electric vehicles and hydrogen power patents. He's also been active in virtual reality and a host of other areas. Clearly a brilliant man, Redmond suffers from a strange form of dyslexia that leaves him unable to aurally process numbers, sequences, times or time spans. to overcome this obstacle he developed a visual system of mathematics he calls "organic math" which has clearly been more than sufficient for him.
We look forward to watching this project materialize.

way cool
Sorry, but I call BS on this one. You can get patents for alot of things that wont work.
One never knows! Keep looking to the skies!!
When I see a working prototype, I will be impressed.
The only perpetual motion machine I’ve seen lately is the Moller Air Car publicity machine.
There WAS news, though of a different company that was building an air car (sky car) for a DARPA contract. I saw it mentioned here on FR quite a few months ago, but I could not find it anywhere on the net a few weeks ago.
Probably, but wireless powered items (e.g., phones and lights), using coil induction, are becoming a reality.
This eliminates the problem with most such vehicles -— weight from carrying ones’ own fuel.
You’d need a heck of an infra-structure, though -— roads would need coils every 10 ft to keep a steady stream of power.
Ion propulsion can not possibly create the thrust required to work within gravity.
NASA does use it in space to propel space probes
Old Hat.
Clutch Cargo had one of these.
He also had the Harrier Jump Jet 25 years before England stole the design from him.
lol....there are some huge hurdles to be jumped before this becomes even practical fantasy.
Best of all, the chicks dig it!
bump ... that’s pretty neat.
I thought ion propulsion only worked in a vacuum. I’m almost positive that that’s the case with the XIPS engines used on DS1 and other spacecraft. Maybe these units are different.
That oughta make those Segway a-holes stop acting like they’re hot sh!ts.
A personal jetpack? Talk about a suicide bomber’s wet dream...
Oh yeah, we’d never spot someone flying through the air
ASTRO BOY!
It works on earth but the thrust is insufficient to do any real work.
I did a dislay of this in like 5th grade using a train transformer for power and a tiny rocket suspended from a thread that used a BB as the ionizing engine.
With the rocket suspended horizontaly, applied power resulted in the rocket swinging in a very slight arc
