30 years solar energy in Germany Prof.Dr. Siegrid Jennsen speaks at the birthday party for the oldest German magazine about solar energy on the booth of Solarpraxis. Sharp concentrating cell Current under development, more than 40% efficiency of the photovoltaic ceell at 500 times concentrated sunlight is the target. Below each lense, an only 7mm * 7mm cell. Trapeze tin roof: installing a photovoltaic Mounting system for photovoltaic modules on a trapez tin roof.. The mounting system is available for all common sizees of trapez tin roofs. Rabbet roof tiles: mounting a photovoltaic 2 rabbet roof tiles are replaced by this photovoltaic mounting system. A similar system for installing a photovoltaic is also available for 'Frankfurter Pfanne' roof tiles. Transparent photovoltaic moduls Look through a photovoltaic window. The 950mm * 980mm sized elements are available with 1,5,or 10% transparency and 55, 50 or 44 W peak. Photovoltaic window MSK - Making Solar Work shows a photovoltaic window. New possibilities for the building integration of photovoltaic at office buildings and shopping centers. Inside a heat pump Schüco makes a look inside a heat pump possilble. The compressor (right) liquifies the coolant with high pressure into the condenser. Skater course surface In the skater course surface is a solar collector integrated. So it's possible to change the scater course in winter for ice skating or to heat the near by swimming pool in summer. Sport ground surface Sport ground surface with heat exchanger. With this, it's possible to head to swimming pool in summer time. In winter, it's possible to use a tennis court for ice skating. Swimming pool heating A solar collector for swimming pool heating can not only be installed on a roof. Solkav shows integration in sports grounds, footpaths and streets. Fair halls Freiburg Intersolar 2006 In the foreground the parking lot, from left to right fair hall 1 to 4, the outside part of the exhibition and the extension of the exhibition area in tents. Cheap vegetable oil micro CHP cogen Because of the cheap Indian Standmotor, the complete CHP can be offered at an far lower price than usual in Germany. Valve controll by a pestle At an low RPM stationary engine are also pestles good enough for the valve controll. The engine looks like, that a good mechanican can repair everything. Cheap Diesel engine Even the starter battery is in India a luxury. Normal to start with a starting handle. An engine optimized for the rural areas of India. Photovoltaic from India This photovoltaic modul from Central Electronics is complete made in India. Starting with the silicon are all parts “made in India“ Sun watch - landmark of the Indian hall The exhibition area from India on the Hnnoer industry fair 2006 starts with a big sun watch. Shrads bring luck First he lets the photovoltaic module fall down, later he even steps on it. It does not matter, this new CIS module from OderSun withstands the bad treatment. Flexible CIS Photovoltaic Silicon shortage is no problem, photovoltaic can be produced with many better features out of other materials. Here a flexible CIS modul. Flywheel to store electric power Simple iron. Because the equilibration of wind energy fluctuations is an stationary task, expensive super materials do not pay off. Flywheel storage For off grid systems with wind energy, the flywheel storage equilibrates the continual fluctuations of the wind energy. 5 kWh storage capacity and 200kW peak power for 90 seconds. Enercon E82 wind power plant The biggest attraction in hall 13 was the Enercon 82 wind power plant Look at the details of the wind energy technic from close distance. Gas - biogas - fuel cell Many different sorts of gas can be used in the hot high temperature fuel cell to be converted into electric power and 400 degree hot used air. The used air can be used for industrial applications. Hot high temperature fuel cell The fair sensation at stationary electric power production. 49% efficiency at electric power and for many industrial appliciacations suitable 400 degree used air temperature. CHP fuel cell instead of combustion engine CHP had been only economically for large consumers. This fuel cell for Diesel or gas with 1 kW electricity and 4,5 kW heat will make the use in single family houses possible. Hall roofs with photovoltaic 10 years ago, I would have been enthusiatic about the photovoltaic modules on the roofs of the fair halls. Flat escalator from parking lot south to the Hannover fair Spacial compressed tele photo over the several hundred meter lont flat escalator from the parking lot to the entrance of the Hannover fair. Sera wall heating around window How to detour with a copper pipe wall heating around a window shows SERA on his booth. We already wrote about his house of the passive house pioneer from Salzburg. Cotton as liquid tapestry This special cotton is also called liquid tapestry. The material on the demonstration wall is simple made wet. The wet material can be distributed with a spatula. Wall design with cotton How extravagantly is the production of such a wall design? The next page shows, with the appropriate material simple some movements with a spatula. Cotton wall surface On the 3 walls of the booth, a plenitude of different patterns and effects for the wall design. All carried out by cooton.
