The conceptual idea of the proposal as follows :

 

Naturally, the most involved in the car movement is its wheel. For example, to travel 1 km distance standard tire 13 inches makes 483 complete revolutions, and all four tires together – 1932. Here’s a good enough and reliable source of energy, if we can convert it into electricity with high enough efficiency …
Upon contact with the road each tire deforms, whatever the pressure of air in it. This section of the deformation is called “contact patch”. Accordingly, each section of the tire will turn 483 times in one kilometer or in other words, will “vibrate” at a certain frequency per unit time – for example when traveling with 100 km / h an arbitrary point on the tire will change its location radius 14 times per second, or frequency of the vibration is 14 Hz. This means that a well fixed piezo crystal at one point of the tire of this crystal will get alternative current with a frequency of 14 hertz at a speed of 100km / h. It is known that piezo produce electricity when deformed, however its quantities are small and thus not ideally suited to a industrial use. The piezo crystals may have a total face of 1sqm contact area, so that the circumference of the tire can incorporate approx. 207 piezo. Of course they may be located in series, corresponding to the width of the tire, so that the standard tire with 165 mm can take 16 such crystals assembled across the tire width. Conventionally, suggesting that such  number of single-pulses can be obtained with an output power 0,256 W from each piezo crystal. Of course, frequency and voltage are reduced to the standard 12 volts and 50 hertz. Thus, with the sum of the 4 tires under certain conditions we can get significant amount of electricity.
For this purpose piezo are located in an additional ring on the inside of the tire near the tire wall. At one end against the solid crystal base and the other – the inside of the tire (barge). To prevent breakage of the crystals they should be molded (vulcanized) with additional rings (inner tube), which will also be elastic.

1b. Please describe and discuss the testing results
The proposal is at “raw idea” stage. Neither tests are done, nor a prototype manufactured.  The researcher needs to prepare also correct mathematical calculations to ground the idea.

 

SECTION 2: Current Stage of Development

 

2a

To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )
The inventor has an idea for a device, generating electricity from the tire contact with the ground. Additional staff may be needed for clearing the conception and completing all calculations, which can show the industrial potential of the concept. Additional staff and specialized equipment will be needed also for manufacturing of a test prototype.

2b

What are the technical issues that need to be tackled for full deployment, if needed?
The product is at conceptual design stage. The first stage in development of the product is to carefully examine and prepare the necessary calculations which can prove the effectiveness of the idea.

The researcher should strictly calculate the all piezo crystals summary theoretical result of electricity, expected from one tire and yet to prove the idea is sensible and efficient.

The second stage after the mathematical model is the manufacturing of a working prototype. The intensive testing and evaluation of the prototype must confirm the conceptual stage and the idea behind the development.

 

2c

What additional technical resources are needed for the production of this new product?
The inventor is a physical person, as such he lacks any manufacturing equipment. A working model of the conception can be realized relatively easy. This means the preparation of the future prototype can be started with some help from qualified electrician/technician.

A small future company manufacturer of the product must invest in developing producing powers, necessary for manufacturing of small scale production, at the first stage. Basically it will need basic metal processing equipment with the corresponding number of operators and technical staff.

 

 

2d

Overall assessment of the current stage of technical development.
The idea is theoretically possible. The most important point is to prepare the correct mathematical calculations, which can prove the effectiveness of the concept. If this first stage is successful the preparation of a working prototype and its testing will show if the project is of industrial use or not.

 

SECTION 3: Deployment

3a

Define the demands for large scale production in terms of
  • Materials
The materials, needed for manufacturing of the product are conventional, well-known and widely available.

However the main production problem will be the molding of the piezo crystals in the tire. The know-how for such production is a property of certain leading car tire manufacturers.

 

  • technologies, tools, machineries
For starting a small batch production the company will need equipment for tire manufacturing and also some special equipment for rubber molding.

 

  • Staff effort
The inventor has the abilities to provide close monitoring and control during the production process. More specialized staff must be involved in the calculations, as well as preparation of the prototype.

 

 

 

SECTION 4: Overall Assessment

 

1

What is you overall assessment of the technical feasibility of the research result?
The proposed ideal is theoretically and technically possible, however a working prototype must be manufactured. The extensive testing in real conditions must prove the effectiveness and the level of implementation of the concept.
