It's suggesting that Tesla built a Moray device.

I would like to keep pseudoscience discussion away from this forum.

Just on wikipedia there is a ton of info about such devices, and most articles are just thrown into 'perpetuum mobile' devices in start.

'zero point energy' probably just sounds as a cool name for power source of their PM's but nobody, never gave any explanatio or proof of theiir claims.

- especially read ''free energy'' devices

Regarding tesla's car there is no proof that such a thign ever existed and there are no claims from tesla himself, so it is simply more logical that it is just another BS than concluding that laws of physics have gone nuts overnight.

In car, such way as described, capacitively coupleed energy transfer won't work (good enough at least). multi-100 kilowatt magnifier nearby also probably wouldn't pass unnoticed.

Described box, antenna and lack of grounding have little to do with reality,a dn it all rather sounds like it was interpreted by 10 year old kid..

I don't doubt that Tesla did build an electric car, afterall he invented the induction motor and if that was me I would have been quite tempted to drop one into a car as well.

I think that if this 'magic box' did exist, it's more likely that it was an inverter of some kind to convert a DC battery bank into AC to power the motor, as it mentions that it contains vacuum tubes. That's my theory, anyway. I don't think the 'antenna' is an antenna at all, just a high current switch.

Sounds plausible. Vacuum tubes would make a "switching" power supply feasible, the main problem would be you'd need several in parallel.

However, as vacuum tubes electrically resemble MOSFETs in some operational modes, they can be connected in parallel so it isn't outside the realms of possibility.

Maybe Tesla invented the SMPS 50 years early..

Tesla did invent the SMPS in about 1900. He designed Tesla coils to run off DC mains, that used what was effectively a boost converter (with mechanical switch) to charge the tank cap.

Tubes can be conencted in parallel sure enough. But a compact vacuum tube inverter wouldn't have had the power to drive an induction motor big enough to drive a heavy car at highway speeds. In those days, you'd have needed a mess of ignitrons and chokes that would have been about the size and weight of the car.

To give you an idea of the power-to-weight ratio of tube technology, the tube amp I use for playing guitar and bass through is about the size of Tesla's box, weighs about 40lbs and generates a pavement pounding 50 watts. It takes nearer 50,000 watts to make a car go at 90mph.

No talk of things like Moray devices please, they're pseudoscience

As steve says this with tubes won't work very well.

You would also need very high voltage (lots of lead acid's ) to get tubes working at all.
I think that article is mostly BS. And what I don't think is that such threads really have some sense at all.

It is unbeliveable: perpetuum mobile was declared impossible in middle ages, but still today we have such proposals and discussions. And lot of them are even less imaginative than middle age variants!

And you wonder why there are lots of people that fall for the most ludicrous email scams? There are alot of really ignorant people out there, ALOT.

We do have something close to Tesla's magic box nowadays:

This is what's in the T-Zero and probably the Tesla Roadster too.

Now mind you, I have tried to heed the warning of to "Not drink and post", but tonight I drank a bit much and have to... Why? well, probably because I think I'm on Slashdot and have karma points, but won't realize it until tomorrow, and another reason is that I love pseudoscience... Why? Because it's so damned entertaining to the rest of us.

Man, I remember when I was 15 or 16. Back in what? You younguns can calculate my birthday, about 18 years ago to, what? 1988? 1989? yeah. Back then. When you were just being born. Come on TDU you know... Sorry to mention it but.... :)

The internet? What was that? We had BBS's ... Dialing up to someoneâ€™s computer somewhere cross country to talk to groups of people who MIGHT be online to talk about the conspiracy of modern technology and why zero point energy and the electric rocket was taken by the Mobil company back in the 30's, or whenever... You know. That conspiracy... That and why every good invention has been shelved by big oil since then. why? What? How can you be so sure? Let me tell you why...

My friend Bill and I tried everything. TDU, do you remember the advertisements in the back pages of Popular Science for antigravity devices and free energy secrets from Amazing Science corp in the 70's and 80's? I sure do. I WISH I still had the originals to show you. It was great. It sure got the imagination running. We ordered the catalog. WE ordered the books about how to Tap the Zero Point Energy, and how Tesla was going to Power the World with Wireless Technology. At 16 years old we built the Helical ZP energy devices using Horseshoe magnets from Radio Shack hoping we could finally discover the wonders of free energy. We Built some of the FIRST modern Lifters of our time. Really. I built a lifter from the original plans from Amazing Science back when they had you order a black and White TV Flyback Xformer from them and you ordered all the parts from them to build it. Yeah. A really easy to build lifter 20 years ago. No problem. Was it Pseudoscience? No. Not in the least. Was it marketed well to eager to learn Boy scouts? Hell yes.

They don't exist. Really. If they did people would recreate said experiments and there would be peer review. I USED to believe in the man. The Establishment, but come on. If you came up with a truly new and ingenious way to give energy to the world would you keep it for yourself? Some people would, but for every invention to come to fruitatian in history, someone else around the globe has come up with the same idea and has published it to the public for criticism to see how it stands. The same is to be said for this.

I love Pseudoscience. It gives science fiction something to use, it gives us something to dream about and it gives us an impossible goal and a better aim for to improve our lives as humans, people and the human race, but we should never rely on it until someone proves it as science. And that is a rant of a drunken man on a computer that should never have worked by the account of many a person who thought that this technology was just pseudoscience for the masses. To be honest, I would love to have a pseudoscience thread just to have a good laugh and to give support to those who have wasted their life in pursuit of such endeavors. Thank you and goodnight everyone.

Pete

That said, this applies to audio tubes. The sort of tubes used for RF can be very small indeed but are power limited.

I was reading somewhere about the forerunner of the classical "Farnsworth" multipaction tube being based around a power RF valve modified for high peak powers; its not such a stretch of the imagination to use the same effect to produce a high frequency oscillator tube capable of the power levels required....

I Love psuedoscience.
Not because it makes me laugh, but because in it there exists an adventure of discovery.
I know there is an awful lot of crap out there, but I refuse to close my mind to such stories.
Maybe it's the child in me, maybe it's the scientist, I haven't proved yet that they don't work.
As soon as we close our mind to the future of science, we fail our future generations.
I like to look for the similarities in psuedoscience, find a common denominator, or several.
Science fiction of yesterday is the science fact of today.
Tesla's car stinks of psuedoscience, it does not talk of any huge battery bank, or driving around
a large tesla coil, it talks of a box of valves, an aerial, and some metal rods. This has similarities
to other unmentionable devices that break forum rules, so why we are even allowed to discuss this is beyond me.
Long live psuedoscience!
