Re:Who was first? (with video)
If you had checked at the end of the page and http://jlnlabs.imars.com/gfsuav/gfsuav.htm you would had seen that the guy is giving credit to Hatton and gives a brief history of machines based on the same physics.

Plans for building your own
There are plans to build your own version of this aircraft here, along with quite a few videos of it in flight. I'm amazed by how stable and under control it looks in the video of it flying outdoors in a wind.

DIY rc coanda effect saucer (with plans)
http://jlnlabs.imars.com/gfsuav/index.htm
Besides, there's a company claiming to have "invented" this type of craft years ago (hp says 2002):
http://www.gfsprojects.co.uk/
so is the business model the following?
1. patent stuff others invented before (and maybe forgot to patent it)
2. profit
3. ???

Building your own radio controlled flying saucer
If an albeit clever amateur can build his own radio controlled flying saucers, then I for one, believe they have been tested for a long time by the military. The flying saucers which are based upon the Coanda-effect could actually have been around since the 30's, with a fuel consumption which is 1/3 of a helicoptre's. Depending on the 'flatness' of the dish, you could create saucers which are more suitable for hovering, like the radio controlled GFSUAV or more suitable for high velocity travel, where the dish works more like a wing, like those who people from time to time tell they have been seeing flying extremely quickly over the sky.
What really freaked me out, was that the GFSUAV's odd shape, (which is not quite like the regular, frisbee shaped flying saucers), I have seen in a book about UFO's when I was a child. Some of the unclear (and many years ago not so convincing) photographs, clearly showed flying saucers with a structure on top of it, just like the GFSUAV, but that long ago, I just dismissed those saucers as being unclear shots of hub caps or something.
More people ought to be surprised when they discover the similarities between some of those odd UFO shapes on older pictures, and the GFSUAV with the 'hat' on the top of the dish.
Inside it you could have either a propeller or a jet engine, but what's most fascinating, is that the GFSUAV is electric, driven by state of the art lithium batteries! -

humm.. what a waste..
They could just build one of these..

with a measured 1500% efficiency..
-or-
one of these
http://jlnlabs.imars.com/vsg/index.htm
which has a measured COP of 3.46% and is acutally fusion..
it already exists.. just need a large scale version of it

Far superior to the Airscooter will be the Liftercraft, composed almost entirely of balsa and aluminum foil! Silent, cheap, and almost sensual in design...

Re:The means of getting there is the best part
as crazy as it sounds, a theory behind this lifter gizmo is found here, my favorite the asymmetrical attraction experiment.
as one friend puts it "it is like pulling your body up into air by your own arms grabing your hair"
another one is putting the wires in a vacuum called the "unlinked" lifer found here.
I'm very excited to replicate it, me and a friend are preparing for a replication maybe a toy today but tomorrow it might be a serious transportation technology. -

Re:The means of getting there is the best partExcellent observation from you, this is a new cutting edge propulsion technique, I have been studying this for the last year, I ran across this site which hosts amateur experiments in this phenomena, the made a crude working anti-gravity device, so far there is no solid physical explanation to why it flies, some have theorized that it is ion wind, I was surprised that NASA patented this propulsion technique, I'm too lazy to dig up the link now.
There's a perfectly solid explanation --- it is electric wind. You can hold your hand underneath one (assuming you're willing to risk being electrocuted by the insane voltages these things run off) and feel it. Space ion drives work just the same way, only they're much more energetic.
They're a neat trick, though. Alas, the largest one I've seen reports of --- the Maximus II --- weighs 190g, can carry a payload of 60g, and needs a power supply that can deliver 300W to make it work. If I've done my sums right, that means that an average 1.5V AA cell could probably run one for about thirty seconds --- provided you could find a cell that would deliver the necessary current. And you'd have to fit all the cell plus the HT converter within that 60 grammes.
Be a neat trick if you could make it work, though.
The other problem is that they tend to accumulate charge. They work by positively ionising the air at the top, attracting it towards the negative electrode at the bottom, and then stripping off the charge as the air goes past the electrode. But you're not going to strip off all the charge, which means that your lifter is going to lose positive electrical charge (because charge is conserved). In other words, it'll become negatively charged... which means it's going to have a tougher job accelerating the air and staying aloft. In the lab this isn't a problem because they're connected to a grounded power supply with a wire, which keeps the amount of charge constant. A free-flying one is going to have problems, though.
But if you could solve that, then some fun things are possible. Theoretically, of course, sunlight provides about one kilowatt per square metre. Modern solar cells are about 20% efficient. So your one square metre of solar cells will provide your 200W of energy... get your cells light enough, and you could build a lifter that would fly indefinitely in sunlight!

Re:"Still gets the cold shoulder"Duplicated?
Wow, those beakers look all glowy and hot. But it's not cold fusion. Taking a look at the recipie they used will show you why. It's a few chemical reactions catalyzed by electricity & heat, and free radicals from the electrolysis of water. The glow is from the electrodes because they are made of platinum and tungsten (you know, the same thing that glows nice and bright in light bulbs when you pass electricity through it).
From the recipie page:
Here is my recommended recipe for an experiment to demonstrate the effect:
This shows that they know full well what's happening in the beaker; they're just looking for suckers to buy into it. The impurities in the water are usually enough as it is to get a heat surplus, let alone with this addition.
1. Take a 250 ml glass beaker, fill to about 200 ml level with 0.5 molar
(0.5 M) K2CO3 -- potassium carbonate solution -
Re:My analysis
If they were dealing with purely chemical reactions, can you explain how Ohmori and Mizuno ended up with "Hg, Os, Kr, Zn, Cu, Ni, Fe, Cr, Si, and Mg -- with anomalous isotopic content" in the reactor ?
Also, the results of Naudin's experiments show an efficiency of the reactor well above 100% (up to 258%). The reactor boils up much more water than it should given the amount of electricity it uses. Where's all this "extra energy" coming from ? It *may* be from some unknown exothermic chemical reaction, but strangely there are no traces left of this reaction.
I've clicked on this /. article out of curiosity, vaguely remembering "cold fusion" as an outright hoax from several years ago, but I followed the links and changed opinion. I know Mr Naudin for his works on Lifters and electroaerodynamics, and I trust him as a "garage researcher". I firmly believe that there's something happening in these glowing pots full of K2CO3 solution, though I cannot say for sure what it is - nuclear fusion, or something even more exotic ? But it is producing energy, and I'll see if one can harness it into something useful. -
Re:Cold Fusion experiments for everyone...My big problem is his calculation of input power.
If you look at the power meter picture, you'll see 0.347 kWh of electricity used.
He converts this to an input power of 347 watts - which is (pardon my French) cuillons (that's 'bollocks' for the non-Francophones).
0.347 kWh used in 30 minutes is 694 watts input power - thus (as someone has pointed out) he has just made a dangerous lightbulb.
It's an elementary mistake, but buried in so much garbage that it's easy to miss.

Re:Cold Fusion experiments for everyone...
Here is where the "magic" really is. You see, the "Cold Fusion Reactor" is plugged into a 220volt socket. If you unplug the 220volt power supply the light goes out.
If he really had a reaction that was actually creating energy, you could unplug the power supply and the reaction would continue. Infact the reaction would continue to grow and a means of throttling the reaction would be necessary.
What he really has here is a rather dangerous light bulb. It's none too efficient either. -
Cold Fusion experiments for everyone...
Hi - I just wanted to tell you that there is a guy - Jean-Louis Naudin - who performed many cold fusion experiments recently, using different setups, with different kinds of electrods.
It seems that he is successful in getting more power produced than power eaten (around 200%).
You'll like all his experiments (full description, RealPlayer videos and full results are publicly available) at:
http://jlnlabs.imars.com/cfr/index.htm
If there are real physicists here, please comment his results, it can be interesting.
Jean-Louis is also the guy who successfully replicated the Lifter (electrostatic propulsion). -
On the Subject of Ion Wind and LiftersMuch criticism has been thrown at "Lifters" simply because it is believed that these devices use Ion Wind to propel themselves and thus they are nothing more than intriguing toys not worthy of serious study by scientists. Well, this is completely false.
What the author of the Wired article failed to mention, unfortunately, was that an experimenter by the name of Jean-Louis Naudin has been experimenting with Lifters for some time now, and has done a number of experiments which prove that Lifters do not use ion wind for their propulsion.
The experiments he conducted include one where the aluminum and copper wire were unlinked from each other and the copper wire is placed in a sealed vacuum tube, then once the power is switched on a propulsive force is seen.
And another experiment has the aluminum portion of the lifter fully enclosed in a cardboard box and the unlinked copper wire is then lowered near the box and an upward motion is still seen when the device is powered up.
Then yet another experiment shows that the lifter device can still generate an upward propulsive force even when fully enclosed in a plastic bag.
I should hope that based on the evidence presented here one can come to the conclusion that this matter is far from settled and that Lifters depend on something else entirely different from Ion Wind for their propulsion.

Maybe Rockets aren't the answer
Maybe your old monitor can take you into space. (Here's About.com's take, a bit popsci.) I thought this was bogus until I saw This mouse flying in a lifter - including RealVideo.
Perhaps we have a workable alternative to rockets available. Rockets are a terrifically inefficient way to get, essentially, a 1 to 8 hour drive straight up. In order to do that we have to spit 100 times our mass out the back. That's a lot of commotion and expense and danger. If the tech shown here actually works, it might make the whole concept of rockets obsolete.
It seems this guy Townsend Brown patented what is now mostly called "ElectroKinetic Drive" back in the late 1950's. It was immediately ignored. But it seems to work quite well, even in a vacuum (I'm still a bit skeptical on this point - IMHO the vacuum test I saw pics of on this site was not sufficient.) Lift capability appears to be on the order of 1 gram per watt, perhaps better than that with good design.
At this point, there are almost 200 successful experimenters worldwide, flying lifters using the 'asymmetrical capacitor'. In Japan they have one over 5 meters wide, flying 15 meters in the air. (one of the photos also shows some cool sci-fi looking high voltage equipment below it.)
All of these devices so far have been powered by external high voltage sources, mostly from old PC monitors. I'm not a HW geek, but I figure if you can build a HV system that generates 15KV to 50KV, and enough continuous power to produce 2.5 or more watts per gram, you could build a completely self-sustained lifter.
Of course, I wanna be the first to do this, so I'm not gonna post it on Slashdot. No, really, I hope that lots of people start experimenting with this, and publish their results using a GPL-type approach to patents, so the major tech is bound up in open hardware licenses. This will prevent those who want to own this tech from patenting every nut and bolt and preventing us from building our own. For example, using attitude sensors and a crossover network to vary lift on different sides and maintain attitude and generate horizontal velocity.
Here and Here are some thrust calculations. The latter has a calculator to design your own. If you build one big enough for me, please give me a ride!
Also, if you follow this up, you'll find lots of interesting and downright spooky connections to UFO's, the Lockheed Stealth Blimp (what was that thing that floated over Phoenix in 1997?) -
