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.
To achieve these aims, the project will be executed in
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.
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
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
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
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
- longer life time of batteries and therefore cheaper
- 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
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
- Realisation of energy management for other local users
such as for instance fast charging station for electric
- 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
- 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
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

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
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
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.
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.
