Power-transmission has for so long been associated with the conduction of electrical currents along copper/aluminium wires that few people now question whether there might be a better way. This proposal poses precisely that question and speculates with some reasoning that the answer might be yes . A key fact is that present-day transmission systems do not attempt to take any advantage of frequency-dependent behaviour of the materials used. This proposal is all about trying to develop and use materials or material configurations which have very strong frequency-dependent properties. In particular, it is argued in this proposal that we can construct a material which has a permeability (an ability to conduct magnetic flux) which is very very high at one frequency and very very low at another (with many orders of magnitude of difference between the two extreme values). If one such material had its peak permeability at, say, 10kHz while another had its trough at precisely 10kHz, we could use one as a magnetic conductor and another as a magnetic insulator and the resulting combination might be a cable which could transmit power very effectively compared with electrical transmission. People who study electromagnetic fields talk about the electric field, E, and the magnetic field , H. In the proposed magnetic transmission of power, we are turning both E and H through 90 degrees compared with their usual orientation but still achieving the same product (E x H) which accounts for power transmission.The development of these frequency-dependent materials / configurations transpires to be related to some fundamental mechanical engineering involving torsional resonant frequencies of units not unlike dumbells.

长期以来，电力传输一直与铜/铝导线上的电流传导联系在一起，现在很少有人质疑是否有更好的方式。这一提议恰恰提出了这个问题，并以某种推理推测答案可能是肯定的。一个关键的事实是，目前的传输系统并没有试图利用所用材料的频率依赖特性。这个提议是关于尝试开发和使用具有非常强的频率依赖特性的材料或材料结构。特别是，在这个建议中，我们可以构造一种磁导率（传导磁通量的能力）的材料，它在一个频率上非常非常高，在另一个频率上非常非常低（两个极值之间有许多数量级的差异）。如果一种材料的磁导率峰值在10kHz，而另一种材料的磁导率低谷恰好在10kHz，我们就可以用一种材料作为磁性导体，另一种材料作为磁性绝缘体，这样就可以制成一种电缆，与电力传输相比，它可以非常有效地传输电力。研究电磁场的人谈论电场E和磁场H，在提出的磁传输功率中，我们将E和H与它们通常的方向相比转动了90度，但仍然得到相同的乘积（E x H），这就是功率传输。这些与频率相关的材料/结构的发展与一些基本的机械工程有关，这些工程涉及到与哑铃类似的单元的扭转谐振频率。
