alternating eye network as ballast, replacing resistors, but then they are not clamped, but recharged 100 times per second, and the energy stored by the capacitor is used in an external circuit
But if you conjugate an ionisgor - a capacitor with a double electric layer - into the handle of the pan, and place it in the bottom a heating element, then such a “miracle * can become a reality
The fact is that the specific charge of purifiers is tens of thousands of times greater than the charge of conventional condensate-to-energy energizers, and they are increasingly being used as energy storage devices in a wide variety of devices, even playing the role of storage batteries in cars. So with a piece of meat or meatballs can easily cope.

BICYCLE WITH FLYWHEEL
"I'm a lover fast driving on a bicycle, but I don’t want to put a motor on my bike - and appearance por-tit and makes a lot of noise, - writes our regular reader Yegor Masalsky from Orsk. - So I came up with a solution: what if we put a flywheel on the bike? The flywheel engine is silent and easy to hide under a beautiful casing. The flywheel can be spun up at home, before going down the lane, and when traveling, you can recharge it when going down the hill*.
The idea of a flywheel (inertial) engine is known. In England, a prototype troll! i6yca was even built, the flywheel of which was spun at stops from the street power supply. E past
issue of our magazine, in the special issue "Step into the Future" "we described () the work of a schoolboy from Tegut Dmitry Kovalev, who not only suggested the idea of an inertial bus for transporting passengers from Surgut to the village of Fedorovsky, but also calculated the parameters that a flywheel engine should have. iBy the way, we suggest Egor to return to his idea and figure out what numerical parameters - mass, size and speed - a bicycle handwheel should have)
Inertial drives have many attractive features - large stock energy, noiseless operation, cleanliness, but there are also disadvantages transfer shaft. After all, the flywheel rotates at a constant high speed, and a rigid clutch, like a gear, will not work, and friction clutches are often ropw and uneconomical, converting a lot of energy into heat. By the way, the bicycle flywheel is easy to connect to the wheel. It is enough to insert a transfer roller between the wheel and the flywheel, as shown in the figure. This mechanism is also far from perfect, but it is pro - and quite functional, in contrast to the ratchet and stars proposed by Yegor.
This could make Yegor's idea feasible. But, alas, it's not just about mechanics. Assessing Yegor Masalsky's idea as curious, PB experts remembered the so-called gyroscopic effect. Any rotating body, and the flywheel is no exception, must keep its position in space.
Almost all bicycle drive designs have a common drawback that reduces their efficiency. This vice consists in the uneconomical expenditure of muscular energy when changing efforts from one leg to another while the pedals pass through the "dead spots" (the vertical position of the connecting rods). Most of the muscular effort at this moment is directed to the axis of rotation of the pedals and does not so much useful work, how much increases the wear of the carriage bearings.
It is not for nothing that cyclists remove the connecting rods from a vertical position before starting to move. As a result, the working stroke begins with a partial loss of muscle energy, which causes premature fatigue of the cyclist. The proposed improvement of the bicycle drive eliminates this drawback, allowing lovers of long trips to ride in an economical mode, rationally using muscle energy, expending it almost like during normal walking.
To do this, the drive design uses a device to interrupt the interaction of the connecting rods with the drive sprocket, which ensures the free and fast passage of the connecting rods with sector pedals near the “dead spots” due to inertia. General form The design of a bicycle drive with an inertial interrupting device is shown in Figure 1, where the connecting rods 1 (with pedals) mounted on the carriage shaft 2 have a movable (sliding) connection with the drive sprocket 3 due to the interaction of spikes made on the sleeve 4, fixed on the right connecting rod, and diametrical grooves - on the drive sprocket 3.
The grooves allow the cranks to quickly pass through the ineffective zone, and the 5 flex coil spring softens the blow at the end of them. freewheel. As you can see from the drive figure, constructive change only the connection of the drive sprocket with the right crank is exposed, so such a drive can be made on any model of bicycle. To do this, a sleeve with protrusions is made from ZOHGSA steel according to the drawing pos.4, which is welded to the connecting rod removed from the bottom bracket shaft and modified in accordance with the drawing pos.1.
The drive sprocket is also being finalized - grooves are made in it for the protrusions of the bushing. The spring is made "cold" from carbon wire with a diameter of 4 - 5 mm and contains one incomplete coil. The ends of the spring can be bent at home after heating the bend of the wire over a gas burner. The guide washer 10 is made according to the drawing from any steel. When installing the drive sprocket, the spikes of the bushing 4 are inserted into its grooves, on which the washer 10 is fastened with three M4 screws.
Limiter 6, made of soft wire and fixed on the drive sprocket by bending the ends on its jumper beams, prevents the spring from moving away from the sprocket plane when it is under tension during operation. Next, the right connecting rod 1 with the drive sprocket is fixed in the usual way on the shaft 2 of the bicycle bottom bracket using wedge 9. When installing the spring, one end of it is installed in a suitable hole on the drive sprocket, and the other bent end wraps around the connecting rod near the pedal.
To expand the adjustment of the force of the spring 5 on the drive sprocket, a series of holes is additionally drilled along the diameter of the wire to install the bent end of the spring in them. The drive works as follows. In the initial period, for example, when installing the right foot on the right pedal, which is in the upper position, the connecting rods 1, together with the shaft 2 and the sleeve 4, rotate until the working interaction of the hub spike with the drive sprocket 3, while the spring 5 is compressed and creates a torque on the drive After applying muscular effort to the right pedal, the drive sprocket is set in rotation - and the bike accelerates.
When the right pedal approaches the extreme lower position, the working interaction of the connecting rods (hub spike) with the drive sprocket is interrupted by delaying the rotation of the connecting rods relative to the drive sprocket after the pedal force is reduced due to the reverse action of the spring and the inertial movement of the bicycle. In this case, the spring supports the rotation of the sprocket and removes it from interaction with the connecting rods.
As a result, at the beginning of the next working cycle, the connecting rods pass the vertical position with some reverse angular displacement relative to the drive sprocket, which ensures a free transition of the vertical position and the next accumulation of the spring for the left crank. Then the drive process is repeated. The free transition of extreme upper and lower positions by the pedals eliminates the loss of muscle energy when changing cycles of their work, which increases the efficiency of the drive.
In steady state operation, the connecting rods are delayed in rotation, and then they effectively push the drive sprocket. As a result, pedaling is carried out in an economical "push" mode. This mode of operation allows without undue effort and for a long time to maintain high speed, which is similar to keeping a flywheel spinning with an intermittent tangential force. The delay in the rotation of the connecting rods helps to compensate for the inertial forces acting on the cyclist's legs in the area of "dead spots" during their rapid rotational movement.
The efficiency and stability of the drive is affected by the spring accumulation force, which is selected depending on the weight and physical fitness of the cyclist. If, after the working stroke, the connecting rods do not move away from the drive sprocket, then a more elastic spring must be installed. And vice versa, if for a free transition of the pedal top position a noticeable muscular effort is applied to it and during the working stroke there is no working interaction of the connecting rods with the drive sprocket - then the elasticity of the spring must be reduced.
This can be done by selecting the diameter of the spring wire. For normal operation drive, the amount of reverse movement of the cranks must be less than their initial angular displacement. Under these conditions, the initial torque on the drive sprocket is maintained during transient operation, which further enhances the damping properties of the spring to smooth out peak loads during push rotation of the drive sprocket.
When mastering riding a bicycle with such a drive, the cyclist requires some attention to control the uniformity of rotation of the drive sprocket with free wheeling of the connecting rods. When certain skills are obtained, the uniformity of rotation of the drive sprocket and the amount of reverse movement of the connecting rods are automatically maintained and do not present any difficulties and discomfort.
Experimental sea trials within 3500 km confirmed the efficiency and reliability of the drive. Compared to a conventional bicycle, fatigue is noticeably reduced when long trips, which expands the possibilities of the cyclist. Perhaps the springing of the pedals against the drive sprocket can also have its place in big sports, as well as the springing of the back of the blade against the heel of the shoes of cross-country skates.

Frame 1 welded, tubular section. The drive wheel 2 consists of a rim 3 with tires 4, side discs 5 with flanges 6 and bearings 7 and is installed in the slots 5 of the frame 1.
The inertial propeller consists of a flywheel 8, a shaft 9, a double-lever pendulum 10, a freewheel 11. The flywheel 8 includes a working body 13, made in the form of a thin-walled cylindrical ring, a cross 14 mounted on the shaft 9. The working body 13 is located on the perimeter of the cross 14 of the flywheel 8, inside the driving wheel 2. Double-lever pendulum 10 with one end on bearings 45 is mounted on the axis 16 of the pedals 17, on the other ends of the pendulum 10 shaft 9 with a flywheel 8 is installed on bearings 18. The pendulum 10 can rotate relative to the axis 16 at a small angle and is supported by springs 19 in a suspended position, excluding unauthorized contact of the flywheel 8 with the rim 3, since the axis of the shaft 9 is offset relative to the axis of the wheel 2.
The foot, muscular drive of the flywheel 8, located on one side of the wheel 2, includes a drive sprocket 20 mounted on the axle 16, a double sprocket 21 located on the finger 22 of the pendulum 10, and an asterisk 23 with a freewheel clutch 11 mounted on the shaft 9, sprockets pairs are connected by chains 24.

The front wheel 27 with the steering wheel 28 is controlled, mounted on the rack 29 in the sleeve 30 of the frame 1, or two paired, steering steerable wheels 31, located at the rear of the bicycle on the axle 32, with a common rack 33 installed in the sleeve 34 on the frame 1, on the rack 33 from the bottom, the gear sector 35 is fixed, which is engaged with the gear sector 36 of the steering wheel 37, the steering wheel 37 is installed in the sleeve 38 on the frame 1 .
The drive motor 39 is connected by a chain to the sprocket 26. The seat 41 is rotatable. Brake shoe 42 is mounted on pin 43 on frame 1 near seat 41 and connected to lever 44; when braking, shoe 42 is pressed directly against tires 4 of wheel 2.
The work of a bicycle with an inertial propulsion. When pedaling 17, the force is transmitted through sprockets 20, 21, 23, chain 24 and freewheel 11 to flywheel 8, simultaneously through sprockets 25 and 26, chain and freewheel 12, the force is transmitted to wheel 2, as a result, the bicycle moves and spins flywheel 8, which accumulates the kinetic energy of the moment of inertia of rotation of the working body 13.
When you press the pendulum 10, the latter, together with the rotating flywheel 8, rotates through a small angle (Fig. 5-7), periodically, for a short period of time, presses the perimeter of the working fluid 13 of the flywheel 8 against the inner surface of the rim 3 of the wheel 2 at point A (on line AA ), the contacting surfaces of the working fluid 13 and the rim 3 are covered with a friction composition, part of the kinetic energy is transferred to the rim 3 of the wheel 2, a reaction force P of the rim 3 arises, which causes a force R d forward movement flywheel 8.
In addition, during the period of contact of the flywheel 8 with the rim 3 of the wheel 2 at point A (on the line AA), the speeds of the masses of the points of the working fluid 13 change and an instantaneous center of rotation (MCP) of the working fluid 13 appears on the contact line AA, the MCP speed is zero, in this instant manifests the moment of force M of the mass mcp of the working body 13 on the shoulder of the instantaneous radius R relative to the MCV, this moment of force M also causes the force R m of the translational movement of the flywheel 8. As a result, two forces of translational motion act on the bicycle from the flywheel 8:
a) force R d moment of inertia of rotation of the working fluid 13 of the flywheel 8,
T \u003d J 2 1 / 2, where T is the kinetic energy of rotation of the working fluid 13,
a J=m r 2 , where J is the moment of inertia of the working fluid 13 (kg m 2), m is the mass of the working fluid 13, r is the radius of the working fluid 13, - angular velocity rotation of the working fluid 13;
b) the moment of force M of the mass mcp of the working fluid 13 of the flywheel 8 relative to the MCV,
and M=mcp·R, where M is the moment of force of the mass mcp of the working fluid 13 relative to the MCV; mcp - mass of the part of the working fluid 13, which is located above its horizontal diameter; R is the instantaneous average radius of the working fluid 13 when the working fluid 13 rotates relative to the MCV.
With a mass m of the working fluid of 5 kg and 2000 revolutions per minute (40000 rad per second) of the working fluid 13 and its radius r equal to 0.3 m, the kinetic energy is T=9000 kg·m 2 ·rad·sec 2 .
When a rigid body rotates about an axis, the moment of inertia plays the role of mass. During the movement of the bicycle, the energy consumption will be about 3 kgm per second, which will ensure the speed of the bicycle at least 50 km / h for 150 seconds without recharging (unwinding) the working fluid 13. During this time, about 50% will be spent maximum stock its kinetic energy. It will take several seconds to recharge (unwind) the flywheel 8 with the working fluid 13 to the calculated value of the number of revolutions. The period of contact of the working fluid 13 of the flywheel 8 with the rim 3 of the wheel 2 is 4-6 seconds at intervals of 8-10 seconds.

Conceptual version of a futuristic electric inertia bike city bike(City Bike), which was designed by designer Devrai Bhadra, is a traditional bike that, in addition to being environmentally friendly, brings great pleasure while driving through the streets.
The coating of this invention is made of fiberglass, while the bicycle frame itself is made of carbon fiber. This design makes this vehicle quite light. At the same time, bicycle wheels are built small engines, which save it from the weight of the spokes and, accordingly, reduce friction and resistance during movement.
According to the developer's idea, the same mechanism allows the cyclist to increase the control of each of the wheels, because the power is transferred directly from the engines to the wheels, which allows the City Bike to remain stable in conditions of changing speed. The inertia that is generated during the movement is ideally tuned to each of the cyclists. Thus, through the use of the entire system, cyclists different configuration and sizes can handle this bike as comfortably as possible.
The inertia of this vehicle is transmitted from working circuit, main gear and wheels, as a result of which the user during the ride has the illusion of maneuvering even when in a stationary position on the spot. This system works similarly to a pendulum, so the driver has the ability to control the bike on different speeds differently.
Usage: as a cargo bike. Essence: a tricycle with two frames and a flywheel has an additional flywheel drive, made with the possibility of interaction by means of electromagnetic controls with the main drive. 9 ill., 1 tab.
The invention relates to a cargo bicycle, a 2-seater tandem is known, to which a trolley is attached, such a design in urban conditions is not convenient due to its storage and it is very difficult to overcome climbs with a load. The goal is to facilitate the design and possible storage at home and transport 150 kg of cargo at a speed of 30-35 km / h. This is achieved by the fact that the bicycle consists of two frames arranged in parallel, with solid wheels, united by one axis, with inside of the right wheel there is a flywheel mounted on a swing bearing, which is pressed onto the axle of the rear wheels, but having separate drives, consisting of sprockets of different diameters, which increase the rotation speed with respect to the wheel several times, bearings are pressed on the ends of the roller, on which the ends of the frames are attached . The drive sprocket is also pressed onto the flywheel bearing, given that the flywheel develops a circumferential speed of up to 700 m / s, and the wheels are a maximum of 12 m / s when the flywheel assists the bicycle, especially when climbing hills, the flywheel drive sprocket has teeth on the front side. The right and left wheels are pressed on common shaft hic, the drive sprocket of the right wheel is mounted on it with teeth towards the teeth of the flywheel, in order to avoid jerk when the flywheel is turned on, it is carried out due to the difference in the diameters of the clutch sprockets and the common shaft itself, which protects against a sharp jerk and does not allow an increase in the circumferential speed of the wheels. The bicycle is controlled by a cyclist sitting on the right wheel, has a common frame with the front wheel. The cyclist sitting on the saddle of the left wheel rotates the pedals with the driven sprocket, the roller of which is fixed on the platform 28, the same cyclist, in order to increase power by extracting kinetic energy from the flywheel, turns off the current supplying the electromagnet 33 from the dynamo rotating the front wheel, the spring unclenches, pushes the thrust washer, which is attached to the pipe, inside which there is a common shaft 9. The other plastic end of the pipe is screwed into the drive sprocket of the right wheel, which moves along the slot to the right and the teeth of the drive sprockets interlock. To increase the circumferential speed, the flywheel drive has, in addition to the driven sprocket, additionally intermediate sprockets of small diameter and large diameter, mounted on one swing bearing, and the “gala” chain transmits rotation to the flywheel drive sprocket. Note: The intermediate sprocket bearing is mounted on a shaft attached to the frame. The flywheel drive is protected from above by a shield, and the sides on one side are protected by the right wheel, and on the other by a cargo box, which is freely inserted between the wheels, its bottom is made of plastic, and a nylon mesh is attached around the perimeter, fixed at the top to the frame. Wheels, a flywheel and frames are cast from sentall containing 65% polyacene and 35% magnesium powder, such a polymer, in terms of density, elasticity, is able to withstand the full load of a cargo bike with a specific weight of P 1.21 g / cm 3. The approximate weight of the main parts is given in the table. In FIG. 1 shows a cargo 3-wheeled bike, side view; figure 2 is the same, plan view; figure 3 is the same, end view; in Fig.4 the wheel assembly of the drive sprocket with clutch teeth, end view; figure 5 is the same wheel, side view; figure 6 flywheel assembly, side view; figure 7 washer pressed onto the flywheel bearing, side view; in Fig.8 left wheel, side view; in Fig.9 a device for connecting or disconnecting the flywheel from the transmission of energy to the wheels, side view. In Fig.1-9 adopted the following designations: 1 rear right wheel, 2 rear left wheel, 3 front wheel, 4 flywheel, 5 cargo box, 6 rocker bearings, 7 flywheel rocker bearing, 8 flywheel drive sprocket, 9 rear wheel shaft, 10 flywheel drive sprocket, 11 flywheel drive intermediate sprockets, 12 driven sprocket right wheel, 13 driven sprocket of the left wheel, 14 driven sprocket of the right wheel, 15 driven sprocket of the left wheel, 16 Gala chain, 17 right frame, 18 thrust tube screwed into the drive sprocket of the right wheel, 19 feed spring for engaging the sprockets, 20 thrust washer that compresses the spring, 21 left wheel pedal, 22 right wheel pedal, 23 washer mounted on the flywheel bearing, with engagement teeth, 24 teeth of the drive sprocket of the wheel, 25 teeth of engagement of the flywheel assembly, 26 handlebar, 27 holder for the left cyclist, 28 platform for mounting the holder and pedal roller, 29 nylon mesh, 30 bottom of the box, 31 leash from the thrust washer, 32 anchor, 33 electromagnet, freely sitting on the shaft, 34 electromagnet holding washers. A feature of the invention is its lightness, providing a flywheel to assist cyclists in climbing, does not require liquid fuel, as required by mopeds or motorcycles. At the end of transportation, the box is removed, folded and it is easy to find a place for storage for it, the left wheel is also separated from the right wheel, there is no analogue to such a bike yet. The work of a cargo bike. The cyclist sitting on the right frame controls the bike, and the movement is carried out simultaneously by two cyclists by pedaling 21 and 22, thereby rotating the sprockets 12 and 13, and the sprocket 10 rotates the intermediate sprockets 11 and 14, transmitting the rotation of the sprocket 8 to the Gala goal, such the flywheel drive device creates a significant circumferential speed for it, without affecting the speed of the rear wheels. The rotation of the flywheel is free until the cyclist sitting on the left frame turns on the current that generates the dynamo rotated by the front wheel, from which the electromagnet 31 will attract the armature 32, and by this it will compress the spring 19 and at the same time attract the washer 20, which connected to a plastic tube, inside this tube there is a shaft connecting rear wheels, the other end of this tube is screwed into the drive sprocket of the right wheel, in this position the flywheel with the wheel are disconnected and each of them has its peripheral speeds, when the electromagnet is de-energized, the spring straightens, shifts the washer, which moves the air sprocket 16 of the right wheel along the slots with its tube, which has teeth towards the flywheel, while its teeth will go behind the teeth of the flywheel sprocket 8, which is why the flywheel will begin to transfer kinetic energy to the wheels, which, having different clutch diameters of the sprockets and the shaft 9 itself, will produce a sharp jerk, and the circumferential speed of the wheels will increase slightly. The flywheel drive is protected from above by a shield, and the sides on one side are protected by the right wheel, on the other hand by a cargo box, a nylon mesh is stretched around its perimeter, wheels, a flywheel and frames are cast from lightweight materials, including sektyl containing 65% polyacene and 35% magnesium powder, such a polymer in terms of density, elasticity is able to withstand the full load on a cargo bike, the total weight without load will be a maximum of 20 kg. economic result. The specified design of a cargo bike is designed to transport agricultural crops. produce from home gardens and city dwellers or small farmers, saving money on travel commuter train or buses, as well as saving money on the purchase of gasoline. Its peculiarity lies in the fact that it does not require separate warehouse due to the fact that it is easily disassembled and can be stored on a balcony or loggia.
