    I find this video very interesting. The distance the power was transmitted over was a fairly short distance with a little less than 90% of the power being converted to DC current. Over the distance of Geo sync orbit to the ground 22,500 miles I think beam divergence would be a problem. The beam may spread out over a wide area to large for practical collection. Just a thought.

    In 1914 Marconi has succeeded in lighting an electric lamp by electricity through the agency of wireless at a distance of six miles. A bulb was attached to a receiver connected with an aerial receiving wire. The transmitter was linked up with a 100-horsepower apparatus, and as soon as the power was applied the lamp lighted and remained lighted so long as the power was kept on.

      Prince Alex Yonwuren kind of, he didn't use lasers but a giant tesla coil which he believed he could use to direct a beam of energy to a receiver that people keep calling "death ray". He also made a system that could transmit energy through the ground but it wasn't as efficient as he wanted it to be.

    Let it be clear. The 83.5% is the the efficiency of the rectina devices, rather than the precentage of the induced power to that of the microwave transmitter. Notice that the power of the transmitter is 500,000 W, the power of the lamps is 2x300= 600 W. Thus, only about 1/1,000 of the energy was "harnessed."

    Basically the narrator lies at the beginning when he says that "34,000W was safely transmitted 1.54km with an efficiency of greater than 82%." Later he says, "Of the calibrated RF flux density THAT FELL ON the 24 square meter rectenna array on June 5th, 1975, 82.5% was collected and converted to direct current output." This means that ONLY THE RECTENNAs were 82.5% efficient - not the whole system.
    From the facts he presented, you can work out that the overall system had an efficiency of no more than 6.12% - and probably much less. He says that they used 1/3rd of the array's power to light up 17 pairs of 300W lamps (but he doesn't say that the lamps actually received 300W each). So we can estimate the power converted to DC at 17*2*300*3 = 30600W. He said they used a 500000W Transmitter
    . Dividing 30600 by 500000 gives you an overall efficiency of 6.12%. But I doubt that the lamps were really receiving 300W each as they looked kind of dim in the video.
    As far as "safely transmitted" goes, it was probably safe only because security guards were there to make sure that no one was anywhere near the 500,000W transmitter, which was generating a "head exploding" level of RF power output.
    Would anyone care to calculate the likely efficiency using Frii's equation..?

      A 500kW transmitter with a diameter of 26m is just short of 1kW per square metre (530m^2 dish area). A 36l microwave oven outputting 1kW has dimensions of roughly 30cm x 30cm x 40cm, with a cross-section of 0,3m x 0,3m = ~0,09m^2. That's 11kW per square metre. Call the transmitter 10 times weaker than a microwave.
      Also, a microwave typically has concentrated zones, not a nice laminar density of power. I don't quite think the power output would be "head exploding", but I get the concern, and I'd be inclined to dial it back a bit.
      Edit: It does seem like the dish must've focused the RF power at least a little at that distance instead of focusing to infinity, otherwise your transmitted power over the 24m^2 area of the receiver array is only 22,6kW.

    • @ThisRandomUsername
      @ThisRandomUsername 4 роки тому +2

      On the small scale, you'd probably be best off with lasers and a high-efficiency solar panel (tuned for your laser's wavelength).
      If you want better efficiency, you'd be looking at this sort of setup, probably using a single transmit and a single receive antenna with a dish on both sides. The matching circuits are relatively standard, and you'd be looking into low-voltage rectifier diodes for the receive side, and a higher voltage drive side with decent MOSFETs. Why not give it a go?
