At present, high-voltage electric lines are used for a power transfer. This method is expensive and required complex devices. As project it is offered a new method of power transfer (mechanical cable transmission) for long distances in the air. This method does not require the electric transmission lines, high voltage equipment, large cost, or very much time for construction. It has high efficiency and is cheaper by hundreds of times.

Introduction At current time, turbo, thermo, hydro, wind stations produce the mechanical energy. This energy is converted to low voltage electricity by electric generators, the low voltage electricity converted in high-voltage electricity, transferred to middle or long distances, converted back to low-voltage electricity and distributed among customers. Many customers' devices convert the electricity back to the mechanical energy (for example, the machines, pumps, locomotive, electric motors, etc.). The short electric lines have the length 20-120 km , voltage 110,000 V, and transfer power 35-50 MW. The middle electric lines have the length 200-300 km, voltage 330,000 V, and transfer power 300-400 MW. The long electric lines have the length 800-1500 km, voltage up 0.75 MV, and transfer up 1.8-2.5 GW. The super large electric lines have length up 2000 km, voltage 1.15 MV, and transfer 4-6 GW. The coefficient efficiency of transferrer is 85-92%. All of the lines are very expensive (tens and hundreds millions of dollars) because the electric lines request many an expensive clean electric cooper (wire), a lot of masts, cost of ground, and long construction time. Terrorists can easy damage the mast and deprive a large region of energy, capability to work.

Advantages of offered method. The offered middle length energy transferrer has big advantages with comparison of the same electric lines: 1) cable transferrer is cheaper then same (equal power) electric line in tens-hundreds times (no masts, expensive cooper wire, ground cost, high-voltage substations, no additional electric generator, transformers, etc.). The artificial fiber is cheap and widely produced by current industry, The current fiber may be used for small and middle (up 300 km) lines; 2) the construction time decreases from some months to some days (install only line); 3) we can transfer a high energy more than current electric lines; 4) we can transfer a huge energy to a very long distance (7000-1000 km), from continent to continent (example, from the USA to Europe and back) with high efficiency (more then electric line efficiency); 5) the cable transferrer can be used for delivery of payload (for example, mail); 6) the cable transferrer can be used as high altitude communication antenna for radio, TV, and telephone; 7) the nanotubes have electric conductivity closed to cooper and offered transferrer can be used for delivering of electricity and communication; 8) terrorists cannot damage the line.

Defect. If no transfer energy, we must spend small energy for cable rotation (if no wind).
