How to transfer energy?
From the school bench, everyone knows that a lot of energy is lost in the wires of power lines. In addition, the shortcomings of this method can be attributed energy transfer: the need for a large number of copper, the high cost of laying the power line, the need to install huge supports.
Why not transport electricity on the most ordinary truck?.. Take as a container batteries, charge - and the way? What happens if we transfer energy by electromagnetic waves? And if you pass energy through a special channel? They can be a waveguide or a column of ionized air...
So, three projects under one motto: "Down with the wire!" And what if, really... down with the wires?!
First of all, the new must always be better than the old. Otherwise, why is it? Therefore, the electrical conductivity of the "plasma" wires should not be less than that of conventional copper wires. Scientists have decided to get it, it is necessary to heat the air plasma to a temperature of several million degrees and, most importantly, keep it up all the time. It turns out that only to compensate for the energy loss by radiation in one cubic centimeter, one has to allocate tens of millions of joules of energy every second. The figure is considerable, and it becomes incomparably greater, taking into account other losses, in particular, the "explosion" of the ionized column - in fact, within its pressure reaches a million atmospheres! In fact, such a "plasma" wire is an artificial sun, with the only difference that we will not have to receive, but spend a huge amount of energy to "feed" this luminary. The transfer of energy in this case is as meaningless as the transfer of water in the sieve.
And what will happen if we transfer energy in the form of ordinary radio waves, "somehow modulate and radiate through a narrow antenna"? With this method, large scattering losses are obtained even with the use of narrowly directional antennas. In addition, the costs of modulation anergy are significant here. Perhaps someday in space such a method of energy transfer will prove quite acceptable.
But what about the special batteries with which you can transfer energy? While they are too heavy, and their capacity is very small. To replace power lines by them is like giving up water pipes in favor of forgotten water carriers.
So, three projects with the same error. Looking for new ways of transferring energy, you must always take into account the associated losses.
