You are agreeing that it is possible to get around the inverse square law by using methods other than standard radio transmission. That's great. That is what Tesla was saying. All this nonsense about worldwide power transmission from radio waves is a red herring. Tesla never said that could happen, and neither did he promote the idea. For years, you and others keep throwing this red herring out every time someone tries to replicate Tesla's work and develop his methods for transmitting power using methods other than transverse radio wave propagation. > Are you just assuming that Greg's receiver is receiving pure, unrestrained > > radio waves?

I don't think Tesla ever got the idea that industrial scale power transmission would replace the present wire grid. Tesla's thinking was along the lines of low power lighting, small motors, and self-powered communications devices for the average person. Tesla actually built a working model of remote controlled submarine that was powered and controlled through wireless power. Greg Leyh just built a working model of a motorized bike that is powered by wireless power transmission. There are ways to work around the inverse square law to broadcast power, and Tesla was THE pioneer in this field. Right now, the biggest obstacle to overcoming the limits of wireless power transmission are people who keep throwing out the red herring of the inverse square law. I hope the moderators can see this, and politely remind people who throw out the inverse square law that wireless power transmission is about finding alternative ways to get power to a remote location using non-radiative, non-transverse-wave techniques. As for your comment about plasmas, did you consider the difference between hot plasmas and cold plasmas? A cold plasma exists where the hard matter of protons and neutrons remain at room temperature, but the electrons get up to 10,000 K and higher. However, the electrons can be so spaced out that the high temperature does not affect the environment in an adverse way. Cold plasmas are used in personal hygiene products, food processing, and in many manufacturing processes. There are no laws of physics that prevent plasmas from being useful and efficient means for transmitting power, especially in a closed system. The surface of the Earth, as a whole, is a closed system, and Tesla's intent was to harness this fact for his power and signal distribution system. We must not limit our minds to radiative photon propagation, and instead think about other ways in which energy can be used. I do not know the particulars of Greg's wireless bike. However, from what I know about radio broadcasting, his bike cannot be operating on radio waves. If it was, then people would have wireless powered skateboard parks near radio station broadcast towers; others would be flying battery-less drones in the vicinity of radio towers. Try not to hijack this thread with "Tesla was wrong about wireless power broadcasting due to the inverse square law." Tesla never said it was possible to broadcast power using transverse radiation. He always pointed out that it was impossible, and that Marconi and others would fail where he would succeed (although Tesla clearly underestimated how willing people would be to get power for their radios from a battery or wall outlet). Nobody who is truly researching Nikola Tesla is suggesting that we use transverse radiation to broadcast power. What we are trying to figure out are ways to work around the inverse square law, such as the people who invented fiber optics, those who experiment with cold plasmas, and those who attempt to safely couple a power source with an appliance using primarily the E field. And keep an open mind that if power can be transmitted even a short distance beyond the limits of the inverse square law, then the technology can be improved to transmit the power even further.
