Solar energy: Developing country Italy
Unfortunately, the Solarexpo has pointed only very clearly: What concerns the use of solar energy, Italy is a subnormal developing country. Huge need to catch up.
I searched desperately the remaining fair halls where I expected all the announced exhibit pieces to "renewable mobility in towns". But these were no more than 2 medium sized fair halls.
The most modern domestic hot water technology is a plate heat exchanger on the heating water buffer. I met on the Wels energy savings fair 4 different exhibitors claiming all their system is the best most modern and most secure technology. Help! How to wirte a very objective test report on all 4 suppliers?
I found on the Solarexpo no supplier with flat plate heat exchanger for the immediately fresh hot-water production. Only the solution with many bends through the heating water buffer.
Similar situations like in the fair entrance, pretty female booth staff without knowledge, was found in some exhibition stands. The experts only hidden in the closed part of the booth.
