Now that I have it, my next step will be the perfect flying machine." "An airplane driven by your engine?" Iasked. "Not at all," said Dr. Tesla. "The airplane is fatally defective. It is merely a toy--a sporting plaything. Itcan never become commercially practical. It has fatal defects. One is the fact that when it encounters adownward current of air it is helpless. The 'hole in the air' of which aviators speak is simply a downwardcurrent, and unless the airplane is high enough above the earth to move laterally but can do nothing but fall."There is no way of detecting these downward currents, no way of avoiding them, and therefore the airplanemust always be subject to chance and its operator to the risk of fatal accident. Sportsmen will always takethese chances, but as a business proposition the risk is too great."The flying machine of the future--my flying machine--will be heavier than air, but it will not be an airplane. Itwill have no wings. It will be substantial, solid, stable. You cannot have a stable airplane. The gyroscope cannever be successfully applied to the airplane, for it would give a stability that would result in the machinebeing torn to pieces by the wind, just as the unprotected airplane on the ground is torn to pieces by a highwind. "My flying machine will have neither wings nor propellers. You might see it on the ground and youwould never guess that it was a flying machine. Yet it will be able to move at will through the air in anydirection with perfect safety, higher speeds than have yet been reached, regardless of weather and obliviousof 'holes in the air' or downward currents. It will ascend in such currents if desired. It can remain absolutelystationary in the air even in a wind for great length of time. Its lifting power will not depend upon any suchdelicate devices as the bird has to employ, but upon positive mechanical action.""You will get stability through gyroscopes?" I asked. "Through gyroscopic action of my engine, assisted bysome devices I am not yet prepared to talk about," he replied. "Powerful air currents that may be deflected atwill, if produced by engines and compressors sufficiently light and powerful, might lift a heavy body off theground and propel it through the air," I ventured, wondering if I had grasped the inventor's secret.Dr. Tesla smiled an inscrutable smile. "All I have to say on that point is that my airship will have neither gasbag, wings nor propellers," he said. "It is the child of my dreams, the product of years of intense and painfultoil and research. I am not going to talk about it any further. But whatever my airship may be, here at least isan engine that will do things that no other engine ever has done, and that is something tangible."The Tesla PumpLooking out over the city from the windows of his office, on the twentieth floor of the Metropolitan Tower, hisface lit up as he told of his life dream and its approaching realization, and the listener's fancy could almostxem tốc độ đầy đủ của thủ công bay lạ, trong khi lớn quyền hành tại không nghe máy cày cácnước của sông Bắc, xe ô tô leo lên mặt rất của Palisades, đầu máy đáng kinh ngạcđiện gạt bánh cung điện nhiều dặm một phút và tất cả các khó chịu của mùa hè nhiệt biến nhưtuyệt diệu lạnh nhà hàng máy giảm nhiệt độ của toàn thành phố thoải mái tối đa, chođây là chỉ là một vài trong số những đề nghị của các khả năng vô hạn của phát hiện Tesla đặt."Chỉ cần những gì là phát minh mới của bạn?" Tôi yêu cầu. "Tôi đã thực hiện những gì đã kỹ sư cơ khímơ ước về từ bao giờ phát minh ra hơi nước điện,"đã trả lời tiến sĩ Tesla. "Đó là hoàn hảo quayđộng cơ.

Thả sẽ lăn ra, nhưng một số tiền nhất định của các nước sẽ vẫn còn trênCác tấm cho đến khi nó bay hơi hoặc được lấy ra bởi một số phương tiện hấp thụ. Kim loại không hấp thụ bất cứ cácwater, but the water adheres to it. "The drop of water may change its shape, but until its particles areseparated by some external power it remains intact. This tendency of all fluids to resist molecular separationis viscosity. It is especially noticeable in the heavier oils. "It is these properties of adhesion and viscosity thatcause the 'skin friction' that impedes a ship in its progress through the water or an airplane in going throughthe air. All fluids have these qualities--and you must keep in mind that air is a fluid, all gases are fluids, steamis fluid. Every known means of transmitting or developing mechanical power is through a fluid medium."Now, suppose we make this metal plate that I have spoken of circular in shape and mount it at its center ona shaft so that it can be revolved. Apply power to rotate the shaft and what happens? Why, whatever fluid thedisk happens to be revolving in is agitated and dragged along in the direction of rotation, because the fluidtends to adhere to the disk and the viscosity causes the motion given to the adhering particles of the fluid tobe transmitted to the whole mass. Here, I can show you better than tell you." Dr. Tesla led the way into anadjoining room.On a desk was a small electric motor and mounted on the shaft were half a dozen flat disks, separated byperhaps a sixteenth of an inch from one another, each disk being less than that in thickness. He turned aswitch and the motor began to buzz. A wave of cool air was immediately felt. "There we have a disk, orrather a series of disks, revolving in a fluid--the air," said the inventor. "You need no proof to tell you that theair is being agitated and propelled violently. If you will hold your hand over the center of these disks--you seethe centers have been cut away--you will feel the suction as air is drawn in to be expelled from theperipheries of the disks. "Now, suppose these revolving disks were enclosed in an air tight case, soconstructed that the air could enter only at one point and be expelled only at another--what would we have?""You'd have an air pump," I suggested. "Exactly--an air pump or blower," said Dr. Tesla. "There is one now inoperation delivering ten thousand cubic feet of air a minute. "Now, come over here."He stepped across the hall and into another room, where three or four draughts men were at work andvarious mechanical and electrical contrivances were scattered about. At one side of the room was whatappeared to be a zinc or aluminum tank, divided into two sections, one above the other, while a pipe that ranalong the wall above the upper division of the tank was connected with a little aluminum case about the sizeand shape of a small alarm clock. A tiny electric motor was attached to a shaft that protruded from one sideof the aluminum case. The lower division of the tank was filled with water. "Inside of this aluminum case areseveral disks mounted on a shaft and immersed in a fluid, water," said Dr. Tesla. "From this lower tank the
water has free access to the case enclosing the disks. This pipe leads from the periphery of the case. I turn
the current on, the motor turns the disks and as I open this valve in the pipe the water flows."
He turned the valve and the water certainly did flow. Instantly a stream that would have filled a barrel in a
very few minutes began to run out of the pipe into the upper part of the tank and thence into the lower tank.
"This is only a toy," said Dr. Tesla. "There are only half a dozen disks--'runners,' I call them--each less than
three inches in diameter, inside of that case. They are just like the disks you saw on the first motor--no
vanes, blades or attachments of any kind. Just perfectly smooth, flat disks revolving in their own planes and
pumping water because of the viscosity and adhesion of the fluid. One such pump now in operation, with
eight disks, eighteen inches in diameter, pumps four thousand gallons a minute to a height of 360 feet." We
went back into the big, well lighted office. I was beginning to grasp the new Tesla principle...
