Intersolar fair 2005 in Freiburg |
Intersolar fair Freiburg 2005 | ![]() | ||
A biaxial tracked photovoltaic is the landmark of the Intersolar, which greets the visitors at the entrance. Indeed, not correctly turned towards the sun. |
Fair tents in Freiburg | ![]() | ||
The intersolar fair 2005 was too big for existing 3 fair halls with 12,000 ms ². Not to have to put up tents again it is extended till 2006 by a hall 4 with 4800 ms ². |
A blimp is no zeppelin | ![]() | ||
Above the exhibition center circles a Blimp. Blimp are holding the form by the inside pressure. At a zeppelin, however, by a stiff scaffolding. |
Blimp airship and solar calculations | ![]() | ||
If one has seen the adaptable photovoltaic foil of Sharp just on a photovoltaic fair and sees all at once a Blimp, one catches of course immediately to calculate. |
WLAN rip of, no thanks! | ![]() | ||
11.60 EUR for 2 hours. What should somebody do with such an offer on a fair? An offer with time limit to be consumed in one block is senseless. |
Photovoltaic world record | ![]() | ||

Electic power failure in spite of own photovoltaic equipment | ![]() | ||
Normally a net-coupled photovoltaic equipment switches off immediately if the net has no tension. Protection for electrical engineers maybe just repairing the grid. |
Apartment airing with heat recovery | ![]() | ||
How does a ventilation system with heat recovery function? In the exhibition stand of Aerex had been a very clear explanation for this. |
Comfort ventilation system with summer bypass | ![]() | ||
