Charging Stations

Public charging stations in San Francisco 2009
Some of these special charging stations provide one or a range of heavy duty or special connectors and/or charging without a physical connection using parking places equipped with inductive charging mats.

Okay you see those extension cords extending into charging units? Well it will not be need with the current technology that is being developed in terms of wireless energy transference. I think most who follow this blog will know why. Perhaps while oscillator that exist in car and oscillators that exists in parking spot  are embedded in pavement, will increase the calculated range if this becomes common? At traffic light along  the corridor, or perhaps in the traffic light itself?

Inductive Charging. The primary coil in the charger induces a current in the secondary coil in the device being charged.
Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.

But how will cities recoup the parking spot meter time and adjust for the cost of electricity? Why not throw in your cells phone too since it too can have a oscillator whose charge will be rejuvenated in the electrical presence of the car?  Oh,  you see how Tesla would have been happy, and it really has nothing to do with communism, but more of what should have already been enviable to people to create a much more productive society with out paying a mortgage for electricity.

Basic transmitter and receiver circuits, Rs and Rr are the resistances and losses in the associated capacitors and inductors. Ls and Lr are coupled by small coupling coefficient, usually below 0.2

Resonant inductive coupling or electrodynamic induction is the near field wireless transmission of electrical energy between two coils that are tuned to resonate at the same frequency. The equipment to do this is sometimes called a resonant or resonance transformer. While many transformers employ resonance, this type has a high Q and is often air cored to avoid 'iron' losses. The two coils may exist as a single piece of equipment or comprise two separate pieces of equipment.

Resonant transfer works by making a coil ring with an oscillating current. This generates an oscillating magnetic field. Because the coil is highly resonant, any energy placed in the coil dies away relatively slowly over very many cycles; but if a second coil is brought near it, the coil can pick up most of the energy before it is lost, even if it is some distance away. The fields used are predominately non-radiative, near field (sometimes called evanescent waves), as all hardware is kept well within the 1/4 wavelength distance they radiate little energy from the transmitter to infinity.

One of the applications of the resonant transformer is for the CCFL inverter. Another application of the resonant transformer is to couple between stages of a superheterodyne receiver, where the selectivity of the receiver is provided by tuned transformers in the intermediate-frequency amplifiers.[1] Resonant transformers such as the Tesla coil can generate very high voltages with or without arcing, and are able to provide much higher current than electrostatic high-voltage generation machines such as the Van de Graaff generator.[2] Resonant energy transfer is the operating principle behind proposed short range wireless electricity systems such as WiTricity and systems that have already been deployed, such as passive RFID tags and contactless smart cards.

See once you know this and understand what has happen with our current governments in terms of capitalized systems of cost then you see where the 180 degree turn could have helped all countries in the world benefit from not only communications but a resurgence of the adaptations of technologies that would provide still manufacturing base in order to produce product and stimulate economies? The world may have seemed a different place then it is today.

What's the reference to 'communism' about ?
