Sustainable Development: to meet the needs of the present without compromising the ability of the future generations to meet their own needs
Strategy Mix:
• efficiency – enhanced productivity / resource• consistency – enhanced economies embedded in the natural cycles• sufficiency – new concept of prosperity / satisfaction / material wealth
Management rules:
• the use of renewable natural resources must not exceed their regeneration rates
• the use of non-renewable natural resources must not exceed the rate of substituting their respective functions
• the emissions of pollutants must not exceed nature’s capability to adapt
SUSTAINABLE DEVELOPMENT
1. The concept of noosphere (“nous” – mind, “sphere” – the Earth’s cover) V. Vernadsky, Sorbonne, 1922
2. “Noosphere - the modern stage of the biosphere development (environment) connected with the active role of the Homo sapiens” Edward Le Roy, 1927 г.
3. The theory connecting natural sciences (biospherology) with social science. Pierre de Chardin, 1928
4. Transition from One-Dimensional Development to its Harmonization with Respect to Three (Four) constituents:
{Economic; Ecological; Social} The beginning of the process - 1970s.{Economic; Ecological; Social; Institutional} 1996, Commission on Sust. Dev.,United Nations.
THE CONCEPT OF SUSTAINABLE DEVELOPMENT
“System coordination of economic, ecological and human development in such a way that from one generation to the other the quality and safety of life should not decrease, the environmental conditions should not worsen and the social progress should meet the needs of every person”
Vladimir Vernadsky, 1947

MULTI-DIMENSIONAL MODELING
Multi-dimensional models or „multi-scale” as well as the integrated multi-phenomenological models or „multi- physics” have been developed in time, covering today a large number of applications including the materials science, the nano/microelectronics, the ecological reconstruction, the deactivation of the atomic armament and biotechnologies.
The multi-dimensional modeling approaches (MMD) can be grouped in the following generic categories:
- MMD with the transfer of the parameters – which integrates two or more models associated to different dimensional and/or temporal scales and the resulted parameters based on a model are used as input data for the other models;
- MMD with simultaneously solved multi-dimensional models (in the way used in Concurrent Engineering) – which integrates more mutual influenced models which leads to the necessity of simultaneous simulations with mutual data exchange protocols;
- MMD unitary integrated – consisting of the use of a mathematical device that includes terms associated to different dimensional and/or temporal scales in a unitary configuration.

EXERGY ANALYSIS IX
The aim of the project is to develop a demonstration project for de-polluting the Danube River waters by the production of biomass and conversion to hydrogen for fuelling a stationary fuel cells stack of a leisure complex in the Danube Delta, transport bus and leisure boats for tours in the Delta.
The project shall integrate the results of the last 3 decades of experiments developed in Romania for the de-pollution of different lakes and municipal sewage waters by accelerated production of biomass and processing of the obtained yields and the expertise of several European partners in the biomass reforming, stationary fuel cells and leisure boats.
HYRES I
The researches carried out in Romania, have conducted to the development of economically sustainable technologies for cultivation of selected species of aquatic plants for the obtaining biomass through bio-conversion of the pollutants from sewage waters and polluted lakes and processing of biomass for obtaining valuable products.
Among the selected species the highest performance have been demonstrated with the followings:
Eichornia crassipes,Pistia stratiotes,
These species don’t act invasive and because of the temperate climate in Romania the economically relevant yields last about 150 days/year.
HYRES II
The installations for production of seed plants, realized in Romania, are of greenhouse pyramid type installations, with different capacities and with a reduced consumption of energy (40 % reduction of energy consumption relative to the classical systems).
The process of production of seed plants is based on the bio-treatment process of used water under the following conditions:
Temperature range between 15 – 37 ˚C;pH between 6.5 – 8;CCO-Cr in mg/L : 200 – 1000;Total suspensions mg/l: 800 - 1200Concentration of active substances: 50 mg/l;
HYRES III
The pyramid type greenhouse for production of seed plants is a concrete structure with side walls made of glass. It includes a continuous channel fitted on the available surface at each level. The experimental setups have included a channel of 1,300 m long and narrow of 60 cm. The construction of the channel allows a very slow flow of the sewage water to assure the bio-conversion of the pollutants and the treatment of the water. At the basement of the building there are rooms for laboratories, for biomass processing and other purpose.The pyramidal types of bio-technological installations have the following advantages:
Vertical disposure of the process for efficient land use;Reduce the required land area with 40 – 50 % , versus classical systems;Reduce the energy consumption with up to 80 % versus classical
systems.
HYRES IV
The obtained yields are in the range of 5 – 8 tones of biomass/hectare/day, for an average of 150 days/year or 750 – 1200 tones of biomass / hectare / season. Efficient collection systems have been developed.
The conversion of biomass to H2 may be done based on the following processes:
bio-chemically processing of biomass (anaerobic fermentation),thermo-chemically processing of biomass (gasification).
For the case of anaerobic fermentation of biomass for obtaining biogas, the results that have been obtained on experimental tanks are of 105.4 – 254.7 liters of biogas/kg of biomass with a concentration of methane between 14 – 79.2 %.
HYRES V
• The integration of RES is a very complex subject which requires much more sophisticated analysis;
• There are there major aspects that have to be taken into consideration:
• Environment protection;• Economical impact;• Potential for new businesses
• It should be prepared a paradigm shift in energy engineering;
• Reconsidering the education philosophy in the field of energy;
