1 60% of our energy are not used, let s start to minimize the waste A comment to the members of the Club of Rom June 2008 based on inventions of Prof. Dr.-Ing.,Dr. h.c. Heinrich Reents University Applied Science Südwestfalen, Germany Copyright by Prof. Dr.-Ing. Heinrich Reents

2 Small is beautiful? A new technology to reduce CO² emissions and save energy by using heat power Prof. Dr.-Ing. Heinrich Reents

3 Comparative investments in power plants Micro power plants 1500 Euro/ KW Windmills in the sea 2500 Euro/ KW Solar power plants 4000 Euro/ KW Coal fired power plants 2000 Euro/ KW (CO² problems are not solved, but big energy resources) Natural gas fired power pl Euro/ KW Nuclear power plants 4000 Euro/ KW (nobody knows the real costs of eliminating nuclear waste)

4 Arguments for big power plants We can exploit economies of scale. We need proportionately less energy to bring fuel to big power plants. We can steer, maintain and control the system with only a few specialists. It is easier to increase the efficiency of a single large plant than the efficiency of scattered small plants.

5 Arguments against big power plants High planning costs Popular and political opposition to many kinds of largescale power plant. Costs and loss of energy through the high-, middle- and low -energy distribution networks. Enormous capital requirements ( minimum one billion Euro) Realization only possible on a long timescale

6 Arguments for Micro Power Plants Less capital required for planning Projects can be realized very quickly. ( heating systems get replaced in Germany every year) Technical developments increasing efficiency can be realized in the short term. Electricity is produced where it is needed by the consumer Professional maintenance of the generating system can be integrated with the maintenance of other electrical systems. Low costs per unit A blackout of the energy system is nearly impossible, because each Micro Power Plant can work on its own.

7 Vision of a Virtual Power Plant Nature is teaching us Small is beautiful. A flower takes care of its own energy supply and waste disposal. By using efficient independent information networks we can get high flexibility and safety in energy supply ( using mobile phone systems, for instance, to synchronise the energy supply network) We can switch the energy supply system on and off very quickly Micro Power Plants are elements of the Virtual Power Plant

8 Some Facts and Figures from Germany 1236 power plants with a capacity of GW are generating electricity in Germany. These plants are producing 570 billions KWh every year. The estimated additional demand for electricity up to the year 2020 is in the region of 30 GW. This would mean thirty additional big power plants. At the same time there are 55.5 millions cars in Germany with their own power generators. Those generators have a capacity of nearly 80 GW. There are nearly 40 million heating systems in private households. If we replaced those heating systems with Micro Power Plants with a capacity of 1 KW per system we could get an additional capacity of 40 GW. That is the proof : Small is beautiful will work

9 Wind, Sun and Biofuel In Germany there are wind installations with a capacity of 21.5 GW. Only about 10% of that capacity can be used because the wind is not blowing all the time. There are also solar power plants. These plants operate for less than 900 hours a year because the sun is not shining all the time. So solar power plants meet only 0.3% of electricity demand in Germany. Biofuel power plants and power plants transforming waste into electricity can work 24 hours a day. Micro-Power-Plants can generate electricty 24 hours a day and electricity can be produced where it is needed.

10 Advantages of our technology Our technology can be installed alongside, Micro-Power- Plants in private households and in the transport sector as well as in big power plants. Our heat power system makes less noise than normal gas fired motors. Our technology needs less maintenance than a gas fired motor because our system doesn t need spark plugs and needs fewer changes of oil. Our technology already works with low temperature differences. By using our Heat Power Technology in big power plants a major electricity company could save nearly one billion Euro per year.

11 Additonal advantages Our heat power system can use each kind of energy ( solar energy, gas, heat ) So systems can work on an active (for instance fuel, solar energy) or a passive basis ( for instance waste energy in cars, industrial processes, refineries..) We can use our technology everywhere: heat can be used in the high or low temperature range at any site. So our technology relates to 20% of the world wide energy reserves. The significance of our technology is greater than that of nuclear energy, wind energy, biofuel, photovoltaik, water energy, wave and tide energy, geothermy etc. altogether.

12 Let s talk about markets: everywhere heat is available Cars and Trucks, Cooling systems in trucks and ships Railways and Busses, Ships for civil and military use Conventional power plants, Cooling systems for power plants Nuclear power plants, Solar power plants Small power plants for heat and electricity Micro Power Plants in private households (electricity, heating and cooling) Biofuel power plants, Refineries, Industrial processes etc
