not extracting power from atmosphere: I remember Tesla made some experiment with the car that run 90miles... but that was about air (actually space... they would said "aether") as "conductor" of the energy. That is: there was a powerful RF transmitter tower (the kind Tesla loved so much... very-high voltage Tesla coil driven if I remmeber well, kind of a metallic tower at Colorado Springs... I remember an old picture of it... with kind of a "ball" at top of it, above Tesla's lab building) then the car has a "receiver antenna" made in similar way... and a tuned circuit to get maximum efficiency in the receiving process... The RF energy radiated by the tower was then collected at selective rf receiver at car... then converted to DC for the car-engine ...electric motor. Indeed, it was kind of very early energy harvester thing... the radiated power (many kilowatts I guess) were collected at receiver and provide energy to the propulsion system of the car. Due to the slight attenuation in the 90miles range from transmitter and carefully tuned rx the car was able to get enough power to run... This was a demo of how electric energy can be translated in RF and then radiated in the space for remote powering of devices... just that happened in the kilowatts range of power!  No like RFID and the like... that indeed use very small power and get also very few from harvesting that.Also, I think today is not possible replicate such experiments cause all modern countries have severe regulation on emission power/frequencies... A transmitter like Tesla's one could easy swamp any RF communication in a range of 100 and maybe also 1000miles around!  There was also a kind of race for best idea in energy carring methods... like hi voltage dc vs ac etc and Tesla play a role in that along with other brilliant minds of that age. This experiment had no real applications (till today attention to remote micropowering) cause it obviously creates huge problems to radio communications and exposure to very hi EM fields (possibly dangerous for people and environment in the megawatts/gigawatts range). So... not power from air/atmosphere but... just using "air" as channel.  I read of experiments using air for generate power but that are really much more complex than Esteban's posted funny article... they use kind of suspended ballons (by some kevlar wire I think) at relatively high height from soil... there are that include hi-speed turbine inside... to use jetstreams and the like , hi height hi speed airflows... and other that in kind of "farms" collect charges from clouds... but I think there's nothing more than experiments and academic interest to them... not real potential of future applications if not e.g. in aerospace designs.  Kind regards, Max

Free energy is like a free lunch. How free is it?
Perpetum mobile are not possible, what is possible is to find new ways to capture energy sources that are present in nature. If you have ever lived in a place where there are many thunderstorms, you have probably witnessed "St.Elms fire" and such phenomena. I can tell you it is a terrorizing experience to be caught in such a high intensity static electrical field. Maybe that is when my brain got fried. Anyway, here is an idea to capture natures free energy. Take a wheel like from a bicycle, with a diameter of 30cm. Put it into the position where the axle is horizontal. It has spokes. Add lead weights on each spoke so that the weight is evenly distributed and the wheel turns smoothly. the weights are not fixed, but can freely slide on the spokes, but the space to slide is only 0.1mm. Now start cranking this wheel. When the wheel reaches a certain speed, the centrifugal force will push the weights against the rim. There is pressure between the rim and the weight. If you place a piezo electric generator (google that) between the weight and the the rim, the piezo electric generator will produce electricity. The generation of the electricity happens while the pressure on the piezo element is applied and when it is removed again. You get a sine wave output if you apply the pressure in repetitive cycles. How to get the cycles? When the wheel turns a the critical velocity, where the centrifugal force is 1G, then the weights exert 0 force on the piezo element when at the top and 2G when at the bottom.

Apparently, you did not read the article. The car that Tesla built did not receive power transmitted from a tower. The tower near Colorado springs was a test bed Tesla used before he built his larger tower on the Atlantic coast. Its purpose was to transmit power, but not through the air waves. If you read Tesla's history, you will discover he worked for Edison, designing DC motors and generators. He made many improvements, but he could not convince Edison to convert to his better idea of AC generators. After some arguments with Edison, Tesla went to Westinghouse and told him how much better AC would work. So Westinghouse hired him to make an AC system. Edison then started a propaganda campaign against AC in order to help protect his DC power sales. Eventually, Edison lost, and ended up converting his generators to AC like everyone else. After Tesla finished his work converting the world to AC power, he went on with his experiments to transmit wireless power, using large high voltage coils that were designed to resonate with some natural frequency of the earth. If you examine his patents closely, you will see he was transmitting power through the ground. The high voltage coil was mounted above ground because it would short out if it was buried, and because it needed to be above ground in order to get assistance from the upper atmosphere. The coil was only for inputting power and creating the correct voltages and frequencies needed. The power was sent out into the ground. J P Morgan, a banker in New York was financing his final experiments in this power transmitting tower. But when Morgan discovered that anyone could install power receiver equipment to tap into his power source without paying, he cut off his support to Tesla. Within a short time the tower was abandoned when still in the construction stages. Eventually the tower was dismantled before any power was sent from it. Tesla was also the inventor of radio broadcast. In recent years it was discovered that Marconi got his ideas from Tesla's patents, and his long title of inventor of radio broadcasting was rescinded and given to Tesla. But Tesla considered air wave broadcast to be a poor method of transmitting for communications as well as for power. He figured that 95% of the signal is lost when broadcast into the air. But when broadcast into the ground, most of the signal was conserved. Tesla did however use methods to transmit and receive signals and power through the air, for purposes of power and communication on aircraft. The story of the car did not happen until later, when Tesla had no transmitting towers to experiment with. He was living in a modest apartment, and he built the power transducer in his apartment with a hand full of electronic parts and some tubes that were normally used in radio receivers at that time. He ordered the electric motor made specially to his specifications by Westinghouse. "Due to the slight attenuation in the 90miles range from transmitter and carefully tuned rx the car was able to get enough power to run.". There was no 90 miles range from a transmitter. There was no transmitter. There was only an electronic box that Tesla built to be put into the glove box of the car, and an antenna. The 90 miles means he was able to travel up to 90 miles per hour. This same power source was also able to power a house. Nobody knows what the source of power was that he tapped into. This is because he never patented this method, and kept the details secret. Speculations have been made that he tapped into the same ionizing power source in the upper ionosphere that causes the 100V/ meter voltage gradient at the surface. ei: it is ultimately sun power working in the outer ionosphere layers. Tesla began with the idea to generate power and transmit it to all parts of the earth to provide free power for everyone. He later discovered he could use his equipment to send more power than he generated -- power from the outer layers of the ionosphere where the sun adds power to the earth. This is the power source that is speculated was used to run his car. "Free power", in the sense that you don't pay for the power you consume. And it is the same power source that Esteban originally showed an article which was designed to tap into for free. Only, Esteban's example seems like a very crude way that maybe is not capable of charging a battery very well. You can read the story of Tesla's car here: http://www.tfcbooks.com/teslafaq/q&a_016.htm You will see this is NOT an example of using the air for a transmitting medium to receive power transmitted from a tower on the ground.

This is interesting JP.
By creating a ionized conductive "tube" between the upper and lower layers of atmosphere, i can imagine the monstruous amount of current that will flow between them... Ebookee has a great amount of books about Tesla. regards, Fred.

Hi,
I read in different places... websites etc... seems some talk of free-energy device unknown source, other that talks of atmopheric energy harversting device... and also as I remember , that the car was remotely powered by a transmitter made by Tesla just for that... transmitting power using the air as "channel". Now... I stay with my idea... Tesla found a way to remote power the car ...then run it with the electric motor installed... and it worked around 1930 or something. I belive the story is true, just seems much 90mph as speed... really much... but who knows... spending hundreds Kw of radiating energy or finding a low-loss way to transfer it to the car can also explain that... seems the electric motor mounted in place of ICE was around 80HP... so something about 59Kw not small stuff... and a car can run at 90mph with such engine inside up and running! Expecially if the road goes down... Now someone said that the power that supplied the transmitter used by Tesla was derived from e.g. ionosphere/earth circuit... so was the free energy we are talking about... but not the car by itself. Kind regards, Max

hi
This happens because the wire will form a short circuit that connects the ground to the voltage in the air where you are trying to collect a charge. The result is you have moved the ground voltage to a location above where you are trying to collect a charge from. So as the current begins to flow into the top of the charge-collecting antenna, it will quickly pass down the conductor, and the upper voltage will drop to the ground voltage.

I think the device, if exist, cannot be so small or simple to be carried in the car... expecially in the 30's were just some vacuum tubes available... so not small stuff... everything was big... resistors , capacitors etc I think Tesla used a separate transmitter to power the car remotely. But which kind of energy the transmitter used I don't know... maybe he just bought the electric energy from some electric company... maybe he discovered a way to get free energy from ionosphere/earth ... who knows !? I also think there's much speculation about these issues... cause many people talk/write stuff without understand anything of this stuff... so it's a big mess of pseudoscience and hurban-legends around these facts. Kind regards, Max

I read of a wooden box long 24'' he mounted in the car...then connected to the motor ... and also that he bought some maybe 12 vacuum tubes at a local shop when went to the factory to change the ICE with the electric motor... maybe tubes required for some control circuit than for receive the signal. I guess generated TX signal was at least 100Kw power. Now... if so, I guess the tubes at receiver could be just simple e.g. triodes or something like that... That make me think Tesla made a kind of rf receiver, probably very easy receiver cause of dimensions of the box , but maybe enough to get the power from antenna to the motor... in the 50Kw range. Now... for TX some old tubes are rated hi power 100 Kwatts range and more... an example of that is RCA862 (water cooled, 100Kw range triode). The tube patent by RCA is around 1928... so compatible with Tesla experiment of the car. We have also to consider that Tesla probably had ability to use such "advanced" technology well before commercial distribution of them... cause companies trusted him , at least for some time. Now... suppose Tesla used such 100Kw or more transmitter... and realized a receiver capable of getting 58Kw from the air... well... the car could effectively run then , and no special or fictionary explaination required.I think so: he used hi power tubes for generating a gigantic radiated power... in a way he can then receive it at car with simple/small device connected to the motor and run it. Why not ? Is that the essence of that experiments... carring electric power without cables/wires... but simply air. Kind regards, Max

Tesla was a genius from Croatia who moved to the USA where he found more industries he was interested in. His Idea was to provide free energy for all people, because he thought this would help to remove the reasons for wars. He discovered that when he built machines for free energy, the governments wanted to take his machines to make more war. In his later years, he was more secretive to protect his ideas and keep them from the govenrments for use in more wars. His power transducer used in the car is not known. There have been many speculations by people who read the stories. The scientists usually decide they cannot determine what was the principle and power source. But Pseudoscientists love this story because they can use it to help them prove their pseudoscience theories, like perpetual motion, and free energy from a vacum, etc. Because the details were secret, a pseudoscientist can say he discovered Tesla's secret, and has modified the machine to find treasures long range, or to make free power. But what makes sense? Tesla's later experiments showed that if he built a large high voltage transformer and caused it to create a path (ionized air tube) that reached from the ionosphere to the ground, and AC was applied at the proper frequency, then he could draw surplus power from the ionsphere into his coil, more power than he used to open the path to the ionosphere. Tesla's method of obtaining power from the ionosphere brought DC pulses similar to 1/2 wave rectified AC. The pulses from the ionosphere helped a resonant circuit in his high voltage transformer to increase in power. This resonant circuit was part of the high voltage primary, which he powered to produce the secondary voltage. The power he received can be sent to any power equipment you want... batteries, motors, capacitor banks, etc. But it should be large power handling equipment if you intend to use a large amount of the ionosphere power. There was no ground transmitter that ran Tesla's car. His last tower was dismantled years before. He was living alone in a modest apartment in New York, and had no access to towers and large power broadcasting equipment. Nobody else was experimenting with these towers at that time. There was no power station sending power to the car. Therefore, the most likely source of power is the ionosphere. Tesla gave details how to connect to the ionosphere on many occasions. He even showed all details in his patents. For this reason, it seems likely that this is the source of power for his car. The removable box for his car did not only contain tubes. It also had capacitors, resistors, connecting wires, etc, in the style of old radio connecting methods. If I am correct in my opinion about Tesla's power source, then this box was the controller that kept the primary side of the high voltage transformer to the correct frequency and power level. There were more parts that were located in the car permanently. The 80 HP motor was installed in place of the ICE engine. I suspect there also must have been some large salt water capacitors used for high voltage in those days. And a battery that was used to create the initial power to energize the primary and establish a conductive tube to the ionosphere. When the power circuit begins to work and receive power, then I would think the power is controlled by the accelerator pedal connected to a rheostat for the controller box. But there also must be an auxiliary power circuit for charging the battery to run the lights and instruments. The motor was 220 VAC, so there must have been some small transformer and rectifier to charge the battery. I think all those parts were permanently installed on the car. But Tesla kept the controller circuit secret in a removable box, so nobody would discover the details of how he made this controller. I think it is probably similar to his large megawatt designs, but scaled down for less power, and it probably has improvements that his larger patented versions did not have. Possibly the high voltage transformer was installed permanently in the car, but it may have been inside the electronic control box if Tesla figured a way to miniaturize it when re-designing for low power. We know the antenna plugged into the box. When you read more of the Tesla papers, remember -- there are many pseudoscientists saying they have machines that work on Tesla's same principles. You will read talk about Auras, time travel, gravity transformations, and other strange science. But these are BS. -- Not the same as what Tesla did. Tesla produced real power that you can use to run motors and lights in your home. Not just a lot of talk with fake breadboard demonstrations and secret experiments that are too dangerous for anyone to know about. Read Tesla's patents and see for yourself. Better yet, look at the AC power plug on your wall. It would not be there if Tesla did not design it and the power generating equipment that makes it feed power to you. Best wishes, J_P

I think nobody knows exactly cause he used secrecy in that years... but even if no large tx tower exist anymore at the time of the car experiment ( I simply don't know ) there is the possibility he made a smaller tramsmitter stuff just for that experiment, with a reasonable small antenna for to power the car remotely. Seems to me about difficault he made everything as stand-alone in the car... including a supposed working ionosphere harvesting device... all in that car. I cannot say anything for sure about... but I think the idea of remote powering of the car is far more realistic than having all stuff onboard, also considering space required at that time for electric/electronic devices... huge stuff... and much weight that sum to the car's own weight. I think he wanna just demonstrate to the world the potential of remote powering with that car... no fuel required, no smoke/exausts produced, no noise, no complex carburetors/supply system etc just the car will tap at the air... getting power from rf. It's like today's low-maintenance remote sensors for alarms... no cables...no batteries required and no pain go there... to change them... just they're powered by the central unit by rf. Kind regards, Max

Secondly, none of Tesla's power transmitters sent power through the air using RF. They sent power through the ground at sub-RF frequencies, and used receiving equipment that received the transmitted power from the ground. If the car had a receiver to collect power from a transmission station, then the car would need to have a grounding rod buried in the ground in order to receive this power. But the car is rolling on rubber wheels, and cannot be connected to a grounding rod. So this circuit could not possibly completed to the car when it was moving. Read his patents and you will see the power cannot be received without at least one grounding rod driven a minimum of a few feet into the ground, preferably at least 20 feet deep. Maybe better to look to the concept of drawing power from the ionosphere as Tesla described. Best wishes, J_P
