Dear gentlemen,

13.11.2017

Electric car can be much cheaper & simpler & lighter, than analogous fueled cars, if being synergy of following:

(1) It is a city taxi fed from city electric grid. Personal cars would be banned in the city.

(2) It is absolutely new kind of car in manufacturing and in markets

(3) It is equipped by foldable flat wings with brush or comb contacts at its end for inserting it in a slot of powering box, when the car is traveling.

All other known alternatives of powering are the false and problematic ideas.

More detailed, but shortly it is disclosed just below.

For the moment I suppose the following presumptions and the following system of the city-car powering.

(1) Ordinary city-cars are not more that for 7-9 passengers. Certainly, some special cars and their special guards are possible too for special cases and special routes, but it isn’t problematic to be realized too by special, but known means including non-standard ones.      

(2) The city-cars and conventional cars of all sorts are not contradict each to others, but the last ones must be substituted as soon as possible by the city-cars, can be pilotless in quite nearest future and used as a taxi, while all personal cars must be banned in the cities in nearest future too.

(3) A speed of the ordinary city-car can be no more than 20 m/s (~70 km/h) for safety, for the system simplicity and for energy economy, so it can be provided by powering of not more than 5 kW-10 kW per a car from “powering blocks” of two poles (one of them is the “earth”). (4). The said blocks are located along the city roads, except of some special cases can be provided by city-car battery or by special powering.

(5) The city car battery, if working alone, can provide 3-5 minutes of route, or up to 30 km range, so a gap between the powering blocks is possible to be up to 30 km too for the battery full recharging. 

(6) the powering block is serving to transform its input voltage in save electrical voltage of about 20-40 Volt as its output, can fed the city-car with a help of its flat current collector fixed to the city-car by one end, while its another end is flexible steel comb or brush. The said current collector is foldable and covered by a dielectric.                           

(7) Ordinary, the said powering block is a box placed at about one meter above the road level and can be about 50 meters long and about 20 cm height  with a narrow slot for powering along it.

(8) One block can serve for one line of a road, but ordinary for two lines by both sides of the block.

(9) The slot of the box of the powering block is protected by a shield from rain and dust and has a sewer for washing.

   

In my golden age, I’m interested to see our world to be more
convenient for living as soon as possible, and have very small
interest to earn big money of it. But as a normal person I would be
regretted, if not being granted by your feedback.
