Global warming situation in the world, ground transport role in this world-wide problem, decreasing oil supply and not encouraging attempts to find its equivalent all of above-mentioned problems arose great interest to electric transport. Under such conditions our offer is really actual. It lies in the frames of global researches and is the development of two ideas simultaneously: trolley and electro mobile transport.

In the part of trolley transport it is concentrated on the opportunity to connect and disconnect to contact wire without stopping. At the same time it will help trolley transport to possess automobile maneuverability and accessibility by using energy storage devices.

In the part of electro mobile it is concentrated on the opportunity to charge energy storage devices from external source just during moving. It allows to refuse from some extremely capacious, heavy and expensive charges and to get rid of necessity to waste time for their charge.

On the basis of our offered electric transport power supply system (U.S. Provisional Patent Application 60/799.024) lies a principle of one-line section contact wire. It allows connecting and disconnecting from contact net by simple raising and putting down of current collectors. Moreover it could be done without stopping and slowing down.

Principal chart of power supply is given in the picture.


Power supply system contains:

Sectional contact wire 1, receiving power from stationary electric current source. Adjacent a and sections of contact wire are of different polarity and are separated one from another by c insulators, a and sections length is l, a and sections and insulators are placed along the same line.

There are two 2 and 2 current collectors on every vehicle. These current collectors are of wide range (like in a tram) and are installed one behind another at L= l+m distance, where m is insulator length.

In the places of crossroads and in other places as well where contact wires could cause some problems, the contact wires are not installed.

Raising and lowering mechanism of current collectors 3, electro rectifier block 4, energy storage 5, electro transformer 6, traction electric engines 7. Automatic mechanisms and other devices are not shown in the draft.

One-line contact wire construction is designed and its model is done.

System work in trolley supply regime (current collectors are raised).

When during vehicle moving 2 front current collector touches a sections of contact wire, 2 back current collector touches sections of contact wire. And vice versa, when 2 current collector touches sections, 2 current collector touches a sections.

Electric current, moving through electro rectifier block 4, goes to energy storage 5, and, then through electro transformer 6 goes to traction electric engines 7.

The offered power supply system could be fed by continuous and alternating current net as well.

System work in self-contained power supply (current collectors are down).

If its necessary to change traffic lane: to overtake or to drive around, to drive to the lane or road without contact wires, the current collectors put down and vehicle can move due to its own storage device.

Our offered trolley net should not be general and persistent. Its only important to include road sufficient sections with active trolley wire in transport vehicle route. The number of trolley lines over multilane roads and length ratio of electrified and nonelectrified lane parts depends on their functioning capacity and on level of storage device sophistication as well.

Cargo noiseless trolley-electromobiles could be used at night, so that will cause considerable decrease in day traffic intensity as well as number of traffic jams and accidents.

Separate subject is electro cars. High suspended contact wire is unsuitable for them. To charge electro cars exactly at moving either special areas of streets and highways with low suspended contact wire or mobile charger, where electrocars could be charged during moving are necessary (even airplanes are fueled during flight).

Such mobile charger could contain energy source inside or feed from contact wire.
