Creation of the trademark "sustainable mobility" using new
methods in noise reduction of water turbines, improving
battery performance for transport; providing services for
the feeling of unlimited mobility lifestyle.

The aims of the project are: - To find and establish a market for environmentally- friendly produced renewable energy - This project is intended to prove that ecological local transport is possible by electrical cars, which are powered by renewable energy of local hydro-electric power plants in the most economic form. - Economy is achieved by new fast-charging devices and sophisticated power management. - To find solutions for the producer of renewable energy to market it locally and to make consumers (Public) aware of the benefits fof using all renewable energy locally. Creating a 'Sustainable Mobility' trademark. Methods: To achieve these aims, the project will be executed in three phases: Phase 1: Code name: MICRO-ECOTRANS The first step is to provide and test infrastructure: an existing innovated hydro turbine will be modified, so that the noise level is reduced to a low amount according regulations for house building. This is a pilot project to show that turbines can work in renovated mill houses and generally in living quarters and closely to inhabited areas. Reduced noise level makes the production of electrical energy from hydro-electric power plants more environmentaly acceptable. The first level of power management is intended for loads such as heat pumps and fast charging stations. A fast-charging station will be set up, and a minimum of one electric car will be tested in field tests. Phase 2: Code name: MINI ECOTRANS The second step is mainly scientific work at the Institute of Electrotechnology, TECHNICAL UNIVERSITY OF BRNO with the support of Austrian company NANOLYTICS. Advanced methods and technology of surface analysis will be applied in order to study the surface structure of battery cathodes and anodes undergoing fast charging procedure. Parallel to this scientific work partners for step three will be sought. The results and findings of scientific work will be used to modify and optimize the fast charging procedure. Phase three: Code name: ECOTRANS Preliminary step: set up a local mobility management in Rottenegg, using electric cars. The city is powered by electricity from several local hydro-electric power plants of a local utility company. This infrastructure will be used to develop and test a new design of local transport. The third step is to develop solutions for the transport to the city of LINZ, capital of Upper AUSTRIA and one of the country's industrial centres. Calculation: Time Frame of Phases 1 and 2 is the Definition Phase: Preparatory phase: 3 months Execution Phase: 9 months Implementation Phase: 12 months Costs in ¿: Phase 1 and 2: 1) Austrian participant: 443 000,00 2) Czech Republic particpants: 217 500,00 Total cost for Definition Phase: 660 500,00 Technological Description: 1) Noise level reduction: When building the power station of a hydro-power plant close to a house there is the fact, that vibrations of the fixed mounted turbine will be sensed and heard also in the adjacent flats. According to regulations, the noise level should be below 25dB (A) in living quarters. The easiest solution is to mount the complete turbine block on elastic vibration absorbers. At turbines in area of water level and already installed turbines this complete elastic mounting is impossible. A solution to this problem seems feasible, if the bearing support of the turbine wheel is elastic, and if the housing and cover of the turbine is treated with sound insulation material. The water turbine will be equipped with special bearing supports to eliminate vibrations. 2) Improvement of the existing heat pump: The combination of small hydro-electric power plant, heat pump and low energy consumption building leads, by several synergetic effects, to energy and cost savings, when compared to standard oil or gas heating systems. By driving the heat pump mechanically directly from the water turbine, when compared to standard electricity costs, savings of up to 70% can be achieved compared to standard heat pumps. As a side effect, heating of rooms and warming of water is achived 100% with renewable energy. The elements of a heat pump can also be used for cooling In summer the unit can be used to cool containers. The energy optimizing can only be achieved by power management. The standard control of the turbine will be extended with the newest intelligent software for industrial process management. The software product 'automationX' (from an Austrian company M & R, Graz) will be used. This product, implemented in a paper mill, was part of the success of the high speed world record in 1995 for paper mills in GERMANY. A technological breakthrough will be implemented in fast energy management. 3) Fast charging station: A field test under the guidance of the UNIVERSITY OF BRNO (Prof. Dr. Miroslav Cenek) of an electric car in combination with a fast charging station (Company EPRONA) and the small hydro electric power plant GRIESMUEHLE will be conducted. This pilot project will show the advantages for other hydro-electric power plants, which are in the vicinity of heavy populated cities. According to preliminary studies of Prof CENEK the following benefits exist - less time for charging of electric cars - improved cycle time = greater number of charge and discharge cycles - longer life time of batteries and therefore cheaper leasing rate - economy of time in charging cycle - encreased driving range, and additionally - savings of up to 30% of electric energy in combination with small local energy sources when compared with centralised and distributed energy production. The car will be equiped for first tests with nickel- cadmium accumulators of the French company SAFT. (Approx. 55Wh/kg mass-specific energy). In a second test period the lithium-ion battery should be tested (up to 140Wh/kg mass-specific energy). In addition to the tests performed by the UNVERSITY OF BRNO and Company EPRONA the surface of the battery plates, undergoing fast charging, will be scanned with an Atomic Force Microscope (AFM) of the company 'NANOLYTICS in Upper AUSTRIA. Besides the surface topography of microscopic und submicroscopic structures (3D-presentation) the electric (variation of conductivity) and electronic (electron-density-profiles) properties will also be viewed. 4) Renewable energy - local production and distribution Optimization of the control unit of the CINK-turbine will be done by a new hardware and software tool. The basis is the Soft-SPS automationX from company M&R. The following innovations and technological developments will be accomplished: - Two heat pump units, one for room-heating, one for warm water supply, will be driven mechanically direcly from the turbine as well as the generator for production of electricity. The use of heat pump equipment for the production of cooling energy will be studied in production and application. - Realisation of energy management for other local users such as for instance fast charging station for electric cars. - Realisation of an energy management for independant local production of electrical energy from different renewable sources as hydro-electric power plants, wind mills, bio-gas generators, etc. - Realisation of energy management for the local utility company KARL with regulation of maximum available power in the isolated situation. - Suitable compensation units of newest generation for eliminating voltage drops when connecting the local network to the main grid of ENERGIE AG and vice versa. - Controlling the puls charging characteristic of the fast charging unit and studying the effects on behaviour of the local grid. - Development of a measuring system and design for periodic measurement in real-time, rather than in average like currently in use. - Long term measurements of the network parameters for studying the behaviour of the harmonics in the network under pulsed power conditions. 5) Environmental protection-renewable energy - scientific work The Institut of Electrotechnology, Faculty of Electrical Engineering and Computer Science, TECHNICAL UNIVERSITY OF BRNO will have scientific co-ordination of the whole project and complete co-ordination of the parties in THE CZECH REPUBLIC. Prof Cenek has determined the basic contents of the project 'fast charging' and will conduct the scientific work with support of an AFM regarding surface optimization of the battery plate. The scientific work will be: - mathematical modelling of optimal surfaces - evaluation of surfaces of plates inside the battery with the help of nano-technology - preparing tests and evaluation of results of AFM. - Developing scientific theory - Guiding the implementation in practical application. - Guiding post graduate studies related with fast charging - Presentation of the subject at international congresses and to the scientific community. For the monitoring of batteries a microprocessor controlled system will be developed, the tests will be conducted also by students. The improvements will encrease service life of batteries and total efficiency. The fast-charging procedure will improve availability time. 6) Environmental protection-renewable energy - improvement to the turbine Development, design and construction of a mechanical device to absorb vibrations of the turbine shaft. Measurements will be taken at the GRIESMUEHLE site to determine the frequency of vibration and its source as well as location. Two special constructions will be made to fix the vibration absorber one for each bearing. The vibration absorbers will be adjustable to allow the testing of the turbine frequency range. The devices will be mounted and tested mechanically and measurements will be taken to confirm reduction of vibrations and to find and develop additional methods to reduce the noise level. Corrective actions in design and method will be made and a second type of vibration absorber material and principle will be tested. Two or three adjustment cycles with improvements will be necessary. Additionally, the vibrations of the cover will be examined and a proper device and method will be developed to eliminate also this part of vibration source. Measurements have to be taken up to a point, where the requirements are met for the local Upper Austrian law for the noise level in living quarters. Additionally, these findings will be adjusted to other types of turbines and applications. For these new materials and methods will have to be developed. Phase 3: Code name: ECOTRANS Duration: 3.5 years Aims: Urban and suburban traffic by electric cars as rental cars (car sharing), encreased rates of utilization of this rental service. The project will be executed in Rottenegg, a small town with 5,000 inhabitants, situated close to Linz, the capital of Upper AUSTRIA, with 200,000 inhabitants. The daily local transport is now accomplished by individual car traffic to a parking lot (park & ride) at Rottenegg, switching to public transport (local railway) . The aim of this project is to convert this existing transport, which is not sustainable, to a sustainable one. Method: Replacing a considerable percentage of the existing transport with transport by rented electric cars of a new type. The benefits of this new type of e-car are: 1. technical benefits: - the effects of fast charging are: time savings, energy savings, maximum vehicle range, long battery life 2. economic benefits - fast charging increases operating time of the single e-car compared to standard e-cars (charging time reduced down to less than 20% of standard charging time) - the new design of car sharing reduces the costs dramatically for the single user, without compromising availability of the individual transport (car pool). The realisation of the car sharing conception in this suburban area can create the feeling of the users of cheap and all time available mobility. This feeling of benefit has to be created. Methods and marketing have to be developed. - ecological benefits. Complete use of renewable energy sources (hydro-electric power stations etc.) for the transport (zero emissions car), the components of the car will be chosen according to the idea of sustainability.
