      So far we have been familiar with different solutions of vehicles that have classic drive unit by fossil fuels, hybrid vehicles and purely electric vehicles.
      Our product is an electric vehicle, which connects to powered vehicle and by its motor power starts composition made of these two types of vehicles.
      To a classic vehicle, it provides abilities such as

      1) drive unit on electricity
      Significantly lower electrical energy price comparing the price of fossil fuels even up to 75%. This price is even lower if the consumer has its own electrical energy producer

      2) Carbon monoxide emission amounts 0%, the vehicle does not produce neither exhaust gases nor any other detrimental products.

      3) Level of noise is lower per 90% comparing vehicles with classic drive units.

      4) Vibrations made due to engine operations are also lower as comparing the piston engine it works with less motion of movable parts and less friction.

      5) Energy utilization of energy consumed is up to 90%. Energy consumed that motor converts into mechanical energy has high degree of utilization comparing the engine with internal combustion, which high percentage of energy made by derivatives combustion – thermal expansive energy, releases without the possibility to use it and that energy efficiency level in fossil fuel vehicles is maximum up to 35%.

      6) Vehicle has two driving axles that can work at the same time or by turning on only one of them at the time getting this way characteristic of vehicle for off-road driving.

      7) Vehicle can easily be connected with mechanical connection with other types of vehicles such as semi-trailer achieving its compatibility - same drive unit for different means of transportation.

      8) Vehicle provides higher vitality in traffic to a consumer as it has two separate drive units.

      9) Vehicle provides additional trunk solving the problem of lack of conveying space in case of vehicles with small trunks.

      10) Greater maneuverability of vehicle when having difficulty with parking and traffic jams, as the wheels are steered by direction

      11) Better distribution of masses as external electromotive drive unit gives the role of stabilizer by its mass and prevents skidding by direction in case of sharp maneuvers.

      12) Greater passive security of passengers in case of blow from the backside of vehicle, as in this case electromotive drive unit has the role of amortization area, which will receive greater part of blow energy.

      13) Vehicle has the ability to produce electric energy and supply external consumers when it is in parking position.

      14) Additional self-charging of batteries by solar photovoltaic cells when it is in parking position that can be blinds like pulled out and cover the roof of the trunk of motor vehicle and upper surface of powered vehicle, making batteries self-charging and giving the vehicle protection from strong sun or other atmosphere changes that can damage the car.

      15) Three working modes:

       Electro mod when the vehicle is moved by power of electromotor, which is supplied by electric energy from battery cells.

       Hybrid mod, when electromotor of motor vehicle and motor of powered vehicle work together, vehicle in this situation has sum of power of these two motors, and also in this mod self-charging of batteries of motor vehicle over the electricity generator is realized.

       Mod when powered vehicle starts its own engine on fossil fuels and the engine of motor vehicle is not active; this the situation battery cells are also self-charging by electricity generator, which is placed in the last vehicle on the picture.

      16) Easy access to the components of vehicle in case of service or repair.

      17) The possibility for vehicle theft is difficult as beside the regular barriers against theft it is necessary to decode control interface from the back motor vehicle.

          Headphones have become ubiquitous within the modern world; and for good reason, people love their music. Understandably, people hate when something comes between them and their music. Unfortunately, headphones often become a vexing obstacle between the user and their music. Anybody who uses headphones will tell you that one of the most aggravating situations is when their all set to listen to their music, they get their media device out only to find the cables in a tangled mess.
          Although untangling the headphones only takes a few minutes this is an inconvenience the user would rather not deal with. Enthusiasts and headphone producers have long recognized the problems associated with tangled cables, spending millions of dollars in research and development. Unfortunately, the result of this research has created subpar products that are either too inconvenient to use or are ineffective at improving the users experience. It has been proven many times that users are unhappy with the current headphones design and their poor tangle resistance. Moreover, there is a proven market for solutions. For example, one of many market proven products includes the Kickstarter Project CordCruncher, the project raised over $66,000 in just 30 days ( There are many other Kickstarter Projects that have raised over $600,000 for cable solutions.
          Our solution has the same functionality as the Cord Cruncher Headphones, and more. The product would be cheaper, more versatile, and convenient to use; solving the annoying problems associated with tangled, damaged, strained, or knotted headphone cables while opening up possibilities for more creative uses of headphones. The solutions functions by using a special wire integrated into the headphone cable, the wire is commonly known as memory metal and has riveting properties. The memory metal allows the user to use the headphones, as they normally would, however in order to conveniently wrap the cables up for storage the user may press a button that causes the memory metal to return to a predefined shape. Useful predefined shapes may be a tidy coil, compact winding that contours to an electronic device, or even an Apple Logo! The possible shapes, sizes, and configurations are endless; any shape that cables can be wound into can be achieved automatically by using integrated memory metal. Custom designs may include the user name, a word, or customer design.

                    Flat cable cord (0.4 mm thick rectangular cable with total cable length 100cm) is rolled up on a button sized cable reel from both sides with different length. 1/3 of the total cable length distance is between device and earphones and 2/3 of the cable length is between device and plug for mobile phones (3.5mm phone jack, for any smartphone). The device is therefore located on the upper chest during use.

                    In the centre-point of the cable reel where the cable is rolled up from both sides a microphone and a button to take/stop phone calls are placed. Thus, the cable is rolled up around the micro and the micro (respectively housing) is placed on the upper chest during use and is therefore in the ideal speaking position (distance earphones - housing/micro (upper chest) = 33 cm; distance phone jack - housing/micro (upper chest) = 67 cm).

                    Cable is rolled up synchronously from both sides with different length and different speed in an elegant way. The whole device has a diameter of 26mm and a height of 10mm and therefore looks like a button (fixed with a steel clip). The mechanism is patented (PCT) and the name Rollset trademark protected.

                    Rollset's main features:
                    - High quality in technique and design
                    - No radiation
                    - Handy and easy to use

                    Target audience:
